Description
Technical Field
The invention relates to the field of computer networks and computer software, in particular to a method and a device for updating a resource file URL of a downstream system by a file storage system.
Background
With the development of large-scale internet architecture systems, file storage systems are favored by people. In project development, generally, the uploading and downloading work of files is uniformly relied on a common file storage system, and a downstream system only needs to locally store the URL address of a target resource file. Although the method reduces the development of the file storage operation by developers and improves the development efficiency, the coupling degree between the systems is increased, namely when the file storage system changes, the downstream system partially depending on the file storage system can be affected, so that the problems of data inconsistency and the like are caused.
To solve the above problems, there are two technical solutions in the prior art:
1. based on manual mode
And when the URL address of the resource file in the file storage system changes, manually informing a downstream system to clean the data.
2. Publish-subscribe based approach
The downstream system registers to the file storage system at first, and when the URL of the file resource in the file storage system is changed, the URL used by all the registered downstream systems is automatically updated. This way, the timeliness of data updating is improved.
However, the above prior art still has the following technical problems:
1. due to the inefficiency of manual methods, there may be instances of omission that result in dirty data.
2. Based on the publish-subscribe method, when one URL is changed, the update request is sent to all registered downstream systems at the same time, but when the URL or the downstream systems are too many, high concurrency is caused, so that the burden of the file storage system and the downstream systems is increased.
3. The inability to selectively flush data (some dirty data that will not be used will not be affected even if it is not updated) causes unnecessary overhead.

Examples
The present invention will be described in detail with reference to a specific embodiment, but it should be noted that the specific embodiment is only for better describing the present invention and should not be construed as limiting the present invention.
First, a downstream system needs to register in a registry of an upstream file storage system at initialization. The registration content includes an identification of the downstream system and a token stored in the downstream system. The file storage system opens a query interface for changing the URL of the resource file in the downstream system for the downstream system, and the file storage system only allows the downstream system holding the token to call the interface of the file storage system to query that the URL of the resource file in the downstream system corresponds to the URL of the resource file in the file storage system.
In an embodiment of the present invention, the registration content is stored in a registry, and the identifier of the downstream system includes a domain name of the downstream system, and the token of the downstream system is a character string obtained by encrypting the identifier.
When the downstream system needs to use any resource file, the local URL is used to request the corresponding resource file stored in the file storage system. The file storage system receives a request for the resource file from the downstream system, wherein the request includes the URL of the resource file. Then, whether the URL is the current URL for calling the resource file is judged, and if yes, the resource file is returned to the downstream system. In addition, in an embodiment of the present invention, it may also be determined whether the resource file has a new version according to the URL, and if the resource file has the new version, the resource file with the new version is returned to the downstream system.
However, if the URL is not the current URL that called the resource file, the downstream system obtains the token for the downstream system from the registry, after obtaining the token, calls a URL query interface of the file storage system using the token, and determines the current URL according to a predetermined translation relationship.
In an embodiment of the present invention, determining the current URL according to the predetermined conversion relationship includes determining the current URL corresponding to the received URL according to the predetermined mapping relationship.
Specifically, if the new URL and the old URL of the resource file have corresponding mapping relationships, the current URL of the resource file can be determined according to the mapping relationships.
For example, if a resource file (e.g., a picture file) is originally stored on server a and the IP address of server a is a', the URL of the resource file at the downstream system is a/abc.
Currently, if a server a fails, all resource files on the server a need to be transferred to a server B, where the IP address of the server B is B ', the old URL of the downstream system needs to be updated to B'/abc.
In other words, if there is a rule for converting a 'into B' for all the old URLs, the mapping relationship is only established to replace the part a 'of the old URL with B'.
In addition, there is a case where the determining of the current URL according to the predetermined conversion relation includes determining the current URL of the resource file according to a correspondence table of old and new URLs of the resource file, with respect to the preset mapping relation.
In an embodiment of the present invention, in order to improve the query efficiency of the correspondence table, the present invention further searches the correspondence table by using a load balancer in combination with a fragmentation query policy and a performance balancing policy, so as to determine the current URL of the resource file.
Specifically, the correspondence table is firstly fragmented, and then different fragments corresponding to different URL lookup services are searched. Because the fragments of the corresponding relation table are not uniform and the URL lookup services are executed in parallel, the load balancer adopts a performance balancing strategy, not only records the current performance of each lookup service, but also distributes large fragments to services with good current performance and distributes small fragments to services with poor current performance. When a new URL is found, the other services are notified to stop the search and return to this new URL.
And finally, the downstream system updates the locally stored URL to the current URL according to the determined current URL, and the downstream system can acquire the corresponding resource file by using the new URL to request the file storage system.
Fig. 2 is a schematic structural diagram of an apparatus for updating a URL of a calling resource file of a downstream system by a file storage system according to an embodiment of the present invention, where the downstream system registers with a registry of the file storage system at initialization, and registration content includes an identifier and a token of the downstream system, and the apparatus includes:
a request receiving module 21, configured to receive a request for a resource file from the downstream system, where the request includes a URL of the resource file;
an address determining module 22, configured to determine whether the URL is a current URL for calling the resource file, and if so, return the resource file to the downstream system;
an address updating module 23, configured to obtain a token of the downstream system from the registration center if the URL is not the current URL for calling the resource file, and if the token is obtained, call a URL query interface of the file storage system using the token, determine the current URL according to a predetermined conversion relationship, and update the URL recorded by the downstream system to the current URL.
Optionally, the registration content is stored in a registry, the identifier of the downstream system includes a domain name of the downstream system, and the token of the downstream system is a character string obtained by encrypting the identifier.
Optionally, the address updating module 23 is further configured to: and determining the current URL corresponding to the received URL according to the preset mapping relation.
Optionally, the address updating module 23 is further configured to: and determining the current URL of the resource file according to the corresponding relation table of the new URL and the old URL of the resource file.
Optionally, the address updating module 23 is further configured to: and searching the corresponding relation table by utilizing a load balancer and combining a fragment query strategy and a performance balancing strategy to determine the current URL of the resource file.
The device for updating the URL of the calling resource file of the downstream system by the file storage system is a device corresponding to the method, so the description is omitted.
The method and the device for updating the URL of the resource file of the downstream system by the file storage system can effectively improve the hit rate of the downstream system for calling the resource of the file storage system on the basis of ensuring the data cleaning of the dirty data in the downstream system. Meanwhile, the invention effectively reduces the instantaneity of URL updating and avoids the problem of high concurrency caused by updating the URL.
Moreover, while the operations of the method of the invention are depicted in the drawings in a particular order, this does not require or imply that all of the depicted operations must be performed to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions.
