Specific embodiment

The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.

Before introducing the embodiment of the present invention, first to the deployment scenario of the block chain node local in the embodiment of the present invention into Row explanation, specifically, Fig. 1 is the local structure deployment schematic diagram of block chain node provided in an embodiment of the present invention.Such as Fig. 1 institute Show, the block chain node local disposition of the embodiment of the present invention has message center 10 and at least one functional module 11, wherein message Center 10 can be a treatment progress for being previously deployed at intra-node, which may be implemented registration message subscription Demand and reception simultaneously feed back the functions such as call result 12 to functional module 11.Except special circumstances such as localized nodes equipment closings Outside, message center 10 is usually to be constantly in starting state.Functional module 11 is to be previously deployed at intra-node for realizing certain The module of a little functions, which can be (can be system-Level software, is also possible to apply with hardware and/or software Grade software, or be also possible to realize the subprogram of certain functions) form be deployed in intra-node, functional module 11 can be real Existing function has very much, such as can be and realize function of transferring accounts, authentication function, the write-in of data and deletion function etc., to this Embodiment is without limiting.The functional module 11 of the embodiment of the present invention is after generating remote procedure call request, to block link network One or more nodes in network are sent；Also, the subscription demand registration of remote procedure call request is carried out to message center 10； Message center obtains and handles the feedback message of other nodes offer, call result required for feeding back it to functional module 11 12.Specifically, how the block chain node of deployment of the embodiment of the present invention realizes that the detailed implementation of remote procedure call will be Following embodiments describe in detail.

Embodiment one

Fig. 2 is a kind of flow chart of the implementation method for remote procedure call that the embodiment of the present invention one provides, the present embodiment It is applicable in block chain network, come the case where realizing remote procedure call by the way of decentralization.This method can be with It is executed by block chain node, can preferentially be executed by the message center in block chain node, it should be noted that the present invention is real The block chain node local disposition for applying example has message center and at least one functional module.This method can be by configuring in block chain link The realization device of remote procedure call in point is realized, for example, it may be configuration is in the message center in block chain node The realization device of remote procedure call realize.The device can be realized by the way of software and/or hardware, and can integrate In the electronic equipment of carrying block chain link point, this method specifically comprises the following steps:

S201, the remote procedure call request that message center is initiated according to functional module are ordered for functional module registration message Demand is read, and using functional module as subscriber.

Wherein, the remote procedure call request is that other nodes are sent to one or more of block chain network.

Remote procedure call (RPC) request can be one kind requests service by network from remote computer program, and It is not required to the request it is to be understood that underlying network technology agreement.The remote procedure call request is that have remote process tune in functional module When with demand, the request for being used to request other equipment feedback call result of generation.Optionally.The remote procedure call demand can To be functional module during running its hardware or software corresponding program code, need remotely to call number from other equipment According to when generate.For example, if localized nodes equipment is the lightweight node device of not memory block chain data, if the machine section at this time When money transfer transactions functional module in point device needs to call the balance data of account A, the remaining sum number for calling account A will be generated According to remote procedure call request.

It in embodiments of the present invention, can be into block chain network after functional module initiates a remote procedure call request Other one or more nodes send.Preferably through peer-to-peer network, other node broadcasts into block chain network are sent 's.Alternatively, being also possible in the form of unicast or multicast, sent to other one or more nodes.

Since functional module is the internal processes of node, so working as message of other nodes to the node feeding back call result When, this can not be navigated to by feedback message, which functional module be supplied to.So in embodiments of the present invention, functional module is initiated When remote procedure call request, demand also is subscribed to message center registration message.

Optionally, in the embodiment of the present invention, message center obtains the remote procedure call request that functional module is initiated, then Execute message subscribing.The mode of acquisition has very much, to this embodiment of the present invention without limiting.It such as can be functional module sending out After playing remote procedure call request, the related program code at initiation message center can be triggered, and the remote procedure call of generation The input parameter as the program code is requested, message center will receive the remote procedure call of functional module initiation at this time Request.It can also be that message center is shut off by the remote procedure call request generated to functional module each in localized nodes Mode carry out the remote procedure call request of receiving module initiation, for example, message center is provided with monitor process, the monitoring Process can monitor each functional module disposed in localized nodes in real time, generate remote procedure call when listening to a certain functional module When request, message center will shut off the message request, obtain the remote procedure call request.

Message subscribing demand can refer to that data call corresponding to the remote procedure call request of functional module initiation needs It asks, for example, the message subscribing demand may is that at this time if remote procedure call request is request call current block data Subscribe to the feedback message of current block data；If remote procedure call request is request call money transfer transactions intelligence contract, this When the message subscribing demand may is that subscribe to money transfer transactions intelligence contract feedback message.

It in embodiments of the present invention, can be by the remote process tune after message center receives remote procedure call request It uses request as a message subscribing demand, and registers the message subscribing demand for functional module, in order to which message center is subsequent When getting the feedback message of other each nodes in block chain network, promptly and accurately the corresponding calling of feedback message can be tied Fruit feeds back to each subscriber.For example, after having registered the message subscribing request for subscribing to current block data for the first functional module, when After message center obtains the current block data of each server node feedback, it will be able to, will by the message subscribing demand of registration Current block data feedback is to the first functional module.Optionally, subscribing to demand for functional module registration message can be the function Energy Module registers are subscriber, and register the call result for needing to feed back for the subscriber.Subscriber, which can refer to have, to disappear A side of subscription demand is ceased, subscriber can be the functional module for initiating remote procedure call request in the embodiment of the present invention.Tool Body, message center is that the mode that functional module registration message subscribes to demand has much according to remote procedure call request.For example, It can be the corresponding message team called type of message, be functional module registration is directed to the type of message of analysis far call request The message subscribing demand of column；It can also be and the corresponding readjustment of the remote procedure call request is determined according to remote procedure call request The result that call back function generates is registered as the feedback result of message subscribing demand by function；Other modes can also be used for function Energy Module registers message subscribing demand, to this embodiment of the present invention without limiting.Optionally, how for functional module register needle Message subscribing demand to the message queue of the type of message and how call back function determined according to remote procedure call request, And call back function is registered as to the specific method of the feedback result of message subscribing demand, it will be situated between in detail in subsequent embodiment It continues.

Further, in block chain node different function module there may be simultaneously or whithin a period of time needed for call The identical situation of data.Message center is executed in the remote procedure call request for receiving functional module initiation as functional module When registration message subscribes to demand, it can be message center and identify whether remote procedure call request has existed message subscribing and need It asks；If it is not, then message center is functional module registration message subscription demand, and using functional module as subscriber；If so, disappearing Functional module is added to the subscriber of already existing message subscribing demand by breath center.When other nodes are directed to remotely in network When procedure call request feeds back multiple identical message, message center can be rejected subsequent within the effective time of setting Repetition message.

Specifically, message center obtains the remote procedure call at this and asks if being directed to a certain remote procedure call request Before asking, the corresponding message subscribing demand of the remote procedure call request, and the message are had registered for a certain functional module Subscription demand is not canceled (under normal conditions, for a message subscribing demand, when having fed back call result to subscriber Afterwards, message center can nullify the message subscribing demand), then this remote process tune for receiving of description messages center Message subscribing demand is had existed in the request in the message process of the heart, is no longer needed at this time to send the functional module of the request New message subscribing demand is registered, can be added in the corresponding subscriber of already present message subscribing demand and send this far The functional module of journey procedure call request.If, in the process at description messages center there is no there are this receive it is long-range The corresponding message subscribing demand of procedure call request can execute at this time according to the remote procedure call request received as hair The functional module registration message of the request is given to subscribe to demand, and using the functional module as the operation of subscriber.

S202, when message center receives feedback message of other nodes for the remote procedure call request, according to The corresponding call result of feedback message is fed back to subscriber by corresponding message subscribing demand.

Wherein, feedback message can be other nodes in block chain network according to the remote procedure call request received The message of feedback, for example, the feedback message of other nodes can at this time if long-range call request excessively is to obtain current block data To be the data of current block.If long-range call request excessively is to obtain money transfer transactions intelligence contract, other nodes is anti-at this time Feedback message can be the data for being stored with the block of money transfer transactions intelligence contract, be also possible to money transfer transactions intelligence contract.It adjusts It can be functional module with result and send the data that remote procedure call request wants calling, may be exactly that message center connects The feedback message received, it is also possible to the data obtained after needing to be further processed feedback message.For example, it is assumed that functional module Sending the data called needed for remote procedure call request is money transfer transactions intelligence contract, at this point, if feedback message is to be stored with The data of the block of money transfer transactions intelligence contract, then need that feedback message is further processed, from being stored with money transfer transactions Money transfer transactions intelligence contract is found out in the block data of intelligent contract as the corresponding call result of feedback message；If feedback disappears Breath is exactly money transfer transactions intelligence contract, then feedback message is exactly its corresponding call result at this time.

Optionally, in each node that localized nodes receive the remote procedure call request, it is ready called data When feedback message transmitted by node, message center can listen to feedback message, according to the corresponding message subscribing need of the message It asks, determines each subscriber for registering the message subscribing demand, and the corresponding call result of feedback message fed back to corresponding each Subscriber.It should be noted that message center is being executed according to corresponding message subscribing demand in embodiments of the present invention, it will be anti- When the corresponding call result of feedback message feeds back to subscriber, used mode depends on the mode that registration message subscribes to demand. Specifically, how the mode of demand subscribed to according to different registration message execute the operation of this step will subsequent embodiment into Row is discussed in detail.

Optionally, when multiple nodes into block chain network send remote procedure call request, it is possible to can receive Multiple feedback messages of multiple node feeding backs.When message center receives multiple nodes for the multiple of remote procedure call request When feedback message, multiple feedback messages are formed into message array；Message center is according to corresponding message subscribing demand, by message count Group feeds back to the subscriber, obtains call result so that subscriber screens from the message array.Specifically, when in message When the heart receives multiple feedback messages, Screening Treatment can not be carried out to multiple feedback messages, but it is directly more by what is received A feedback message constitutes message array, and according to the corresponding message subscribing demand of the message array, determination has registered the message subscribing The subscriber of demand, and the message array is fed back to each subscriber for registering with the message subscribing demand, certainly by each subscriber Body carries out Analysis and Screening to the data in message array, determines final call result.Optionally, as the function of subscriber The process that module carries out Analysis and Screening to the data in message array can be, and the highest number of repetitive rate is selected from message array According to as final call result；It can also be the data for selecting its trusted node to feed back from message array as final tune With result；It is also possible to be greater than in message array data that the node of preset ratio (such as 80%) is all fed back as finally Call result.

It should be noted that in embodiments of the present invention, for the message subscribing demand of registration, being fed back when to subscriber After the corresponding call result of message subscribing demand, message center can nullify the message subscribing demand, and release storage is empty Between.Optionally, call result can be quickly found when there are the message subscribing demand for the ease of follow-up function module, The embodiment of the present invention can also be after having fed back the corresponding call result of message subscribing demand to subscriber, and not removing at once should Message subscribing demand (such as can be retain preset time then remove), but the subscriber of call result will be taken from the message It is deleted in the subscriber of subscription demand, guarantees no longer to repeat to send to the subscriber to subscribe to message reading notice.

The technical solution of the embodiment of the present invention, by block chain node local disposition message center, local function mould The remote procedure call request that block generates can carry out the registration of subscription demand by the heart in the message.When other nodes are provided to the node When feedback message, message center finds remote procedure call corresponding to the feedback message and asks according to the registration of the demand of subscription The promoter asked, to be fed back.Thus it solves in p2p network, is communicated between node, but can not be in recognition node Initiate the problem of specific functional modules of remote procedure call request in portion.So as to realize RPC technology in block chain network, Also the multinode advantage of decentralization network has been played, functional module need not fix to some specific node and initiate long-range mistake Journey call request.

Embodiment two

Fig. 3 is a kind of flow chart of the implementation method of remote procedure call provided by Embodiment 2 of the present invention, the present embodiment On the basis of the above embodiments, further optimization has been carried out, has shown in particular and uses the mode of message queue for function mould Block registration message subscribes to demand, and then realizes the concrete condition introduction of remote procedure call, and this method specifically includes:

S301, for message center according to remote procedure call request, whether determination need to call type of message belonging to message Through being at least one there are the quantity of the message queue of corresponding types, the message queue.

Wherein, type of message, which can be, divides the content of the message data of calling required for remote procedure call request It is obtained after class.Type of message may include it is following at least one: block data query messages, Transaction Information query messages, with And intelligent contract calls message.Optionally, since block chain data query message is relative to Transaction Information query messages and intelligence For contract message, granularity of division is thicker, so, fine-grained stroke further can also be carried out to block chain data query message Point, it is divided into current block data query message and history block data query messages etc..It should be noted that the present embodiment is not The type of message of division is defined, the division of type of message can be carried out according to the actual situation.

In embodiments of the present invention, one or more message queues can be registered in the process of message center, for depositing The feedback message of other node feeding backs in the block chain network received is stored up, each type of message in the present embodiment is all disappearing The message queue of storage the type feedback message is provided in the process at breath center.Optionally, in message center process Message queue can be pre-set (as each type of message presets at least one corresponding message queue)；It can also Being created in real time when generating a new type of message.It optionally, can be corresponding by the type of message for calling frequency high Message queue be set as long term message queue；The corresponding message queue of the type of message for calling frequency low is set as disappearing in short term Cease queue.Long term message queue can be in message center process fixed existing message queue, and for short-term message queue, When can not have data in message queue, or subscribe to without subscriber the data of the message queue, which is nullified, Memory space is discharged, in order to which the corresponding message queue of other type of messages is arranged.

Optionally, message center can determine that functional module initiates the request and needs to adjust first according to remote procedure call request Type of message belonging to message data, then judge in the process of message center with the presence or absence of at least one type of message pair The message queue answered.For example, if it is request call current block data that message center, which recognizes remote procedure call request, it can To be first to analyze far call request, determine that functional module initiates the current block data category that the request is wanted to transfer In block data type of query message, then judge again in the process of message center with the presence or absence of block data type of query message Corresponding message queue.Alternatively, it is clear to the specified type of message for needing to subscribe to of message center to be also possible to functional module.

S302, if having existed corresponding message queue, message center is functional module registration for corresponding types The message subscribing demand of message queue, and using functional module as subscriber.

In embodiments of the present invention, if in the presence of the message that need to call type of message belonging to message in the process of message center Queue then can directly initiate the functional module registration of this remote procedure call request needed for obtaining in the message queue The message subscribing demand of data is called, and using the functional module as the subscriber of the message queue.For example, if message center There are the corresponding message queues of block data type of query message in process, then at this time can directly for the functional module registration from The message subscribing demand of current block data is called in the message queue of block data type of query message, and it is remote to initiate this The functional module of journey procedure call request is as subscriber.

Optionally, if the message queue that need to call type of message belonging to message is not present in the process of message center, After at least one new message queue first being created in the message for the type of message in the process of the heart, then execute above-mentioned for function Energy Module registers are directed to the message subscribing demand of the message queue of corresponding types, and using functional module as the operation of subscriber.

It should be noted that in the embodiment of the present invention, for a message queue, more message subscribing demands can be corresponding with With multiple subscribers.

S303, when message center receives feedback message of other nodes for remote procedure call request, Recognition feedback Type of message belonging to message.

Optionally, in embodiments of the present invention, after message center receives the message of other node feeding backs, due to will be anti- Feedback message is added in message queue to be called for subscriber, so wanting the first affiliated type of Recognition feedback message.Specifically, identification is anti- When presenting the affiliated type of message of message, if in feedback message including type of message relevant information (such as message belonging to feedback message Type identification), then it can be identified directly from type of message relevant information and determine type of message belonging to feedback message.If feedback Do not include type of message relevant information in message, then can be and the content of feedback message is analyzed, and then determines that this is anti- Present type of message belonging to message.For example, if the feedback message that message center receives other nodes is current block data, Obtaining the feedback data after analyzing the current block data content in the feedback message is exactly block data, at this time should The affiliated type of feedback message is determined as block data type of query message.

Feedback message is added in the message queue of corresponding types by S304, message center according to affiliated type of message.

Optionally, message center, can be directly each by what is received after type of message belonging to feedback message has been determined The feedback message of node feeding back is all added to the feedback message and corresponds in the message queue of type of message.For example, if having received The current block data of 3 node feeding backs of block chain network then can all add the current block data of this 3 node feeding backs It is added in the message queue of corresponding block data type of query message.

Optionally, the feedback message being added in message queue obeys the principle of first in first out, wherein the data packet stored Include the feedback message of this newly added feedback message and history addition.For the data stored in message queue, due to not true Whether fixed all subscribers have all read required data from message queue, also do not know whether there are also other subscription Side also needs to call the data in message queue；So the data stored in message queue can not be held after subscriber reads Row data-cleaning operation, but only carry out and add feedback message into message queue, when the data in message queue reach storage When the upper limit, the data being added in the message queue at first can be overflowed automatically according to the principle of first in first out, default will overflow at this time Data out are deleted from message queue.Optionally, can previously according to each message queue storing data characteristic (as shared by data The size of memory) it is that different size of queue storage space is arranged in each message queue.

S305, message center notify at least one subscription according at least one corresponding message subscribing demand of message queue Side reads the newly-increased message in message queue, as call result.

Optionally, it is needed for each subscriber for its message subscribing for having registered the message queue of corresponding type of message It asks, so at least one message subscribing demand is all corresponding with for each message queue, and for each message subscribing All there is at least one subscriber in demand, can notify registration should according to the corresponding each message subscribing demand of message queue at this time All subscribers of message demand read newly-increased data from the message queue.

For example, it is assumed that being had registered for subscriber 1 when subscribing to demand for subscriber's registration message and calling current block data Message subscribing demand, for subscriber 2 have registered call the 101st block block data message subscribing demand, be subscriber 3 The message subscribing demand for calling the block data of the 10th -20 block is had registered, the message subscribing demand of three subscribers is all Corresponding block data type of query message.When the feedback message received is added to block data query messages class by message center After in the message queue of type, the corresponding message subscribing demand of the message queue includes that the message subscribing of current block data is called to need It seeks, call the message subscribing demand of the block data of the 101st block and call the block data of the 10th -20 block Message subscribing demand, so calling the corresponding subscriber 1 of demand, subscriber 2 and subscriber 3 to read the message team by these three Newly-increased message in column, as call result.

It should be noted that calling knot corresponding to newly-increased message not necessarily message subscribing demand in message queue Fruit, so in the embodiment of the present invention, it, can when message center notifies at least one subscriber to read the newly-increased message in message queue Can there are some subscribers that call result needed for it is not read in message queue, if such as newly-increased in message queue disappearing Breath is that current block data, at this time subscriber 2 and subscriber 3 can not just find from the newly-increased message of the message queue and need to adjust Block data.But since the process of remote procedure call is usually real-time perfoming, so functional module is initiated remotely The feedback message aiming at the request received under normal conditions after procedure call request, so in actual mechanical process In, occur subscriber do not read in message queue call result required for it probability it is relatively low.

The technical solution of the embodiment of the present invention is adopted as functional module registration when subscribing to demand for functional module registration message The mode of the corresponding message queue of type of message, a message queue can correspond to multiple subscribers, considerably reduce message and order The registration amount for readding demand, improving message center is the efficiency that functional module registration message subscribes to demand, and then is improved long-range The efficiency of the invocation of procedure.

Embodiment three

Fig. 4 is a kind of flow chart of the implementation method for remote procedure call that the embodiment of the present invention three provides, the present embodiment On the basis of the various embodiments described above, further optimization has been carried out, has shown in particular and uses the mode of call back function for function Module registers message subscribing demand, and then realize the concrete condition introduction of remote procedure call, this method specifically includes:

S401, message center are that functional module registration message subscribes to demand, and determines remote according to remote procedure call request Call back function, is registered as the feedback result of message subscribing demand by the corresponding call back function of journey procedure call request, and by function Module is as subscriber.

Wherein, call back function can be the function with certain function, can be used for one from block chain network Or data required for message subscribing demand are determined in the feedback message of multiple node feeding backs.Optionally, call back function has Function can include but is not limited to index function and decryption function etc..For example, can be used for the call back function of index function To inquire transaction data of A account, or a certain intelligent contract of inquiry etc. from a large amount of block data；For returning for decryption function Letter of transfer number can be used to that operation is decrypted to the feedback data of encryption, the feedback data after being decrypted.

Optionally, functional module is when initiating remote procedure call request, contains disappearing of need to calling in the request Call back function needed for ceasing data and calling the message data etc..Message center is being according to remote procedure call request at this time When functional module registration message subscribes to demand, the message data that can be called according to the need for including in request, for the functional module The corresponding message subscribing demand of message data that need to be called is registered, and corresponding call back function will be requested to be determined as remote process tune With requesting corresponding call back function, will by the call back function treated result as the feedback result of message subscribing demand, The call result for feeding back to subscriber will initiate the functional module of the remote procedure call request as the message subscribing demand Subscriber.Call back function generally can be the shared routine that the system level program of block chain node provides.

For example, if the remote procedure call request that functional module is initiated is the transaction note for calling account A from current block Record, required call back function are the call back functions with index transaction record function, at this point, message center can be long-range according to this The subscription demand for calling the transaction record of user A is registered in call request for the functional module, and determines that the remote procedure call is asked Seeking corresponding call back function is the call back function with index transaction record function, will pass through the call back function treated result Be registered as the feedback result of message subscribing demand, and subscription demand of the functional module as the transaction record that calls user A Subscriber.

S402, when message center receives feedback message of other nodes for remote procedure call request, according to correspondence Message subscribing demand determine call back function and subscriber.
