Detailed ways

The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all the structures related to the present application.

Example 1

FIG. 1 is a flowchart of a data downloading method provided in Embodiment 1 of the present application. The data downloading methods provided in the embodiments may be performed by a data downloading system. Wherein, the data download system includes at least a client used by the user, a server for managing the download address, and optionally a CDN for storing data. The client obtains the address of the stored data through the server, and downloads the corresponding data through the address. At this time, referring to FIG. 1 , the data downloading method specifically includes:

Step 110: The client sets a corresponding data download switching identifier according to the current download retry times, and sends the data download switching identifier to the server.

Typically, before the client downloads data, a data download switching identifier is first generated, and the data download switching identifier is sent to the server. The specific type of the data downloaded by the client is not limited in the embodiment. Client download data can also be understood as client download resources.

Further, the data download switching identifier is used to notify the server of the number of retries for the client to download the data in the current downloading process. Optionally, the data download switching identifier is set according to the number of download retries. Each time the client fails to download (such as downloading corrupted data or unable to download data, etc.), it will re-download, and the corresponding download retry times are incremented by 1. For example, when the client performs a download task, it will generate a data download switch identifier. In this download task, when downloading for the first time, the number of download retries is 0, and correspondingly, the data download switching flag is 0. After that, if the client fails to download based on the current download address information, it will retry the download, that is, retry the download. At this time, the number of download retries is 1, and accordingly, the data download switching flag is updated to 1, and so on. If the current number of download retries of the client is 4, the corresponding data download switching identifier is 4.

Optionally, the data download switching identifier can be placed in the request header of the download request, and then the data download switching identifier is sent to the server by sending the download request. Specifically, the server side may include at least one server. When the server side includes multiple servers, the multiple servers can perform different functions. For example, the server side includes a service server that interacts with the client and stores download addresses, and a cloud storage server that manages the download addresses stored in the service server side. It can be understood that when the server side includes a server, a server can integrate multiple functions. Further, the server and the client can communicate with each other. The embodiments of the specific data communication means are not limited.

Step 120: The server obtains the corresponding download address information according to the data download switching identifier.

Specifically, the server side pre-stores the correspondence between the data download switch identifier and the download address information, and at this time, different data download switch identifiers correspond to different download address information. The download address information includes the address where the data is stored in the Internet, and the client can obtain the address of the stored data through the download address information, for example, the download address information may be an IP address. The download address information may also contain the filename of the data. Typically, each item of data may be stored in different devices (eg, different nodes of the CDN or different cloud storages), and at this time, each item of data may have multiple download address data. Further, the server side acquires multiple download address data, and assigns a data download switching identifier to each download address data. That is, the server side stores the corresponding relationship between the data download switching identifier and the download address information of each item of data.

When the server side receives the download request, it acquires the data download switching identifier in the request header, and determines the corresponding download address information according to the pre-stored correspondence. For example, if the data download switch flag is 2, it means that the client is currently retrying the second download, and the previous two downloads (the first download and the first download retry) have failed, that is, the previous two downloads have failed. The download address information cannot download data normally. At this time, the download address information corresponding to the identifier 2 can be obtained. It can be understood that the download address information has not been accessed in this download process. Typically, the server can determine the data that the client needs to download according to the path of the data download switching identifier sent by the client, and then obtain the corresponding relationship between the data download switching identifier and the download address information corresponding to the data.

It should be noted that, in addition to being represented by the number of download retries, the data download switching logo can also be expressed in other ways, such as letter logos or other rule logos. However, no matter how the data download switching logo changes, it can reflect different download cycles. number of trials. And the server side will set a corresponding download address information for each data download switching identifier. It should be noted that the specific generation rule of the data download switching identifier can be formulated by the server and communicated with the client.

Step 130: The server returns the download address information to the client, so that the client downloads data according to the download address information.

Specifically, the server returns the obtained download address information to the client. The client obtains the download address information and accesses and downloads data based on the download address information. It can be understood that, at this time, if the client still fails to download based on the current download address information, it can retry the download, that is, update the data download switching identifier, and send the data download switching identifier to the server, so that the server can feedback new information. download address information. It can be understood that after each download address information stored in the server is fed back to the client, if the client still fails to download successfully, it will continue to generate a data download switching identifier. After that, the server confirms that the data download switching identifier does not correspond. The download address information and notify the client, the client confirms that the data cannot be downloaded. At this point, the client can notify the user that the download failed.

In the above, the corresponding data download switching identifier is set by the client according to the current download retry times, and sent to the server. After that, the server determines the download address information corresponding to the data download switching identifier, and feeds the download address information to the client. The technical means of enabling the client to download data based on the download address information can solve the technical problem in the prior art that the user cannot obtain the required data when the device fails because the user's download process cannot be interfered. When the device fails (that is, the download fails), the client can update the data download switching ID and feed it back to the server, so as to obtain the new download address information through the server and download it, that is, change the download address through the data download switching ID. information, and then realize automatic download retry, so that users can obtain the required data, increase the success rate of data download, and improve the user experience.

Embodiment 2

FIG. 2 is a flowchart of a data downloading method according to Embodiment 2 of the present application. The data downloading method provided in this embodiment is embodied on the basis of the foregoing embodiment. Specifically, referring to FIG. 2 , the data downloading method provided in this embodiment includes:

Step 210: The client sets a corresponding data download switching identifier according to the current download retry times, and sends the data download switching identifier to the server.

Step 220: The server obtains the data download switching identifier sent by the client.

Step 230: The server determines the domain name address information corresponding to the data download switching identifier according to the domain name configuration information, and the domain name configuration information records the correspondence between the domain name address information and the data download switching identifier.

Among them, a domain name, also known as a network domain, is the name of a device or device group on the Internet composed of a string of names separated by dots, and is used to locate and identify the device during data transmission. In this embodiment, each device storing data has a corresponding domain name, which is recorded as domain name address information. Further, the server side pre-records the download address information of the stored data, and configures corresponding domain name address information for each download address information. After that, the server side can set the corresponding relationship between each domain name address information and the data download switching identifier. In the embodiment, the corresponding relationship between the domain name address information and the data download switching identifier is recorded as the domain name configuration information. The embodiment of the setting manner of the corresponding relationship is not limited. After the server side receives the data download switching identifier sent by the client side, it can obtain the corresponding domain name address information according to the domain name configuration information.

Step 240: The server assembles the domain name address information to obtain the download address information.

Specifically, when the client accesses the corresponding device based on the domain name address information, the server that needs to store the domain name address information first translates the domain name address information to obtain the download address information, so that the client can access through the download address information. The embodiment of the translation process is not limited. For example, the server side has the function of a domain name server (Domain Name System, DNS), and the domain name address information can be translated through the DNS. It can be understood that the translation process can also be understood as an assembly process of domain name address information. It should be noted that, during assembly, the domain name address information and the file name of the data are assembled together to obtain the download address information.

Step 250: The server returns the download address information to the client.

Step 260: The client accesses the content distribution network according to the download address information, so that the content distribution network returns data to the client according to the download address information.

In the embodiment, the content distribution network stores data as an example for description, and the client can access the content distribution network according to the download address information. It can be understood that the related operations of the content distribution network mentioned in this embodiment all refer to the operations performed by the edge server accessed by the user. For example, when the client accesses the content distribution network, it means that the client accesses the corresponding edge server in the content distribution network. For another example, when the content distribution network returns data to the client according to the download address, it means that the edge server returns data to the client.

Optionally, after the server feeds back the download address information, the client first determines whether the download address information can be accessed, and if it can be accessed, accesses the content distribution network through the download address information. Otherwise, it is determined that the data cannot be downloaded through the download address information, and it is determined that the download ends.

Further, when the content distribution network returns data to the client, the client receives the data, that is, downloads the data. At this time, the client needs to confirm whether the download is successful, that is, whether the data is normal, if so, confirm that the download is successful, otherwise, determine that the download fails, retry the download, that is, update the number of download retries, and return to step 210.

Further, when the client accesses the content distribution network according to the download address information, the edge server of the content distribution network does not have corresponding data or the edge server is abnormal. For example, the data cache in the edge server of the content distribution network expires, and the server still The message that the data cache expires in the edge server is not obtained, and the server also retains the corresponding domain name address information. At this time, in order to ensure that the client can obtain the required data, it is set that this step specifically includes steps 261-264:

Step 261: The client accesses the content distribution network according to the download address information.

Step 262: The content distribution network confirms whether there is data corresponding to the download address information in its own cache. If there is corresponding data, step 263 is executed. If there is no corresponding data, step 264 is executed.

After the edge server of the content distribution network determines that it is running normally, it determines the cache location of the stored data in its own cache according to the download address information, and determines whether the cache location is accurate, that is, whether accurate data can be found based on the cache location. If yes, it means that the data is stored in the current edge server's own cache, and step 263 is executed. Otherwise, it means that the data is not stored in the current edge server's own cache, and step 264 is executed. It can be understood that if the edge server runs abnormally, the client can be prompted that the data cannot be downloaded, so that the client can retry the download again.

Step 263: The content distribution network returns the data to the client.

Specifically, the edge server of the content distribution network obtains the data in the cache location, and returns the data to the client, so that the client can confirm whether the data is downloaded successfully.

Step 264: The content distribution network returns the source to the corresponding source server.

Typically, the content distribution network has been configured with a corresponding back-to-source address when the service is activated, that is, when data is stored, where the back-to-source address can be understood as the address of the source server. The source server side can be considered as the source device that stores the data, such as a server with cloud storage function. Further, the content distribution network can access the source server according to the back-to-source address, so that the source server feeds back data to the client.

Specifically, when there is no corresponding data in the content distribution network, back-to-source can be performed according to the pre-configured back-to-source address, that is, the source site (in this embodiment, the source server side) that stores the data is found according to the back-to-source address. Generally speaking, when the data stored on the origin server is updated, the data will be pushed to the edge server of the content distribution network. At this time, the content distribution network can be back to the source, that is, when the client accesses the edge server based on the download address information, if the edge server does not cache the corresponding data, it will go back to the source, that is, access the source server to obtain the data. It is understandable that if the client does not access the edge server, the edge server will not take the initiative to fetch data from the source server.

Step 265: The origin server returns the data to the content distribution network, so that the content distribution network returns the data to the client.

Among them, the source server can obtain data by accessing its own storage or pulling the mirror file, and then returning the data to the client through the content distribution network. At this time, setting the source server to return data to the content distribution network includes steps 2651-2653:

Step 2651: The source server confirms whether there is data corresponding to the download address information. If there is corresponding data, step 2652 is executed. If there is no corresponding data, step 2653 is executed.

It can be understood that the data in the source server will be updated regularly. At this time, there may be a situation where the data is not stored in the source server. Therefore, when the origin server determines that the content distribution network returns to the origin, it can determine the location of data storage according to the path back to the origin of the content distribution network, and perform a search to determine whether it still stores the data. If the data is stored, go to step 2652; otherwise, go to step 2653.

Step 2652: The origin server returns the data to the content distribution network.

Specifically, after the source server determines that it stores the data, it returns the data to the content distribution network, that is, the content distribution network obtains the data, and then the client can download the data through the content distribution network. It can be understood that the acquisition of data by the content distribution network is specifically that the content distribution network acquires data from the source server and stores it in the corresponding edge server, and then returns the data to the client through the edge server.

Step 2653: The source server pulls the corresponding data through the mirror file, and returns the data to the content distribution network.

Typically, when the data is not stored in the source server, the data can be pulled by means of an image file. Among them, mirroring (Mirroring) is a type of redundancy. In this embodiment, data on one server side has an identical copy on another server side, that is, mirroring. In other words, mirroring is a form of file storage that can make a lot of data into a mirrored file. Specifically, the source server is configured with data stored in other servers. When the source server confirms that it does not store the data corresponding to the download address information, it can pull the data in the image file by accessing the image file, and feed it back to the content distribution network, so that the content distribution network can download it. The content delivery network can return data to the client.

Above, the client determines the corresponding data download switching identification according to the current download retry times, so that the server determines the corresponding domain name address information according to the data download switching identification, and then the server assembles the domain name address information to obtain the download address. The information is fed back to the client, and the client accesses the corresponding content distribution network according to the download address information, so as to download the corresponding data through the content distribution network. The technical problem that the user cannot get the required data in the event of a failure. When there is a device failure (that is, the download fails), the client can update the data download switching identifier, and feed it back to the server, so as to obtain the new download address information through the server, and download it, and then realize automatic download retry, so that the user can The required data can be obtained, which increases the success rate of data download. At the same time, when there is no such data in the cache of the content distribution network, the source server can obtain the data stored by itself or pull the data through the mirror file by returning the source to the source server, and then return the data to the content distribution. The technical means of enabling the client to download through the content distribution network can further improve the success rate of data download and improve the user experience.

On the basis of the above embodiment, the server side can update the domain name configuration information in real time to ensure the validity of the domain name configuration information. Specifically, the data downloading method of this embodiment is set to further include:

Step 270: The server periodically updates the domain name configuration information according to the weight sequence of the domain name address information.

In this embodiment, the weight sequence of the domain name address information is used as the basis for updating the domain name configuration information. Different domain name address information corresponds to different weighting order. The higher the weighting order is, the higher the ordering of the domain name address information in updating the domain name configuration information is, the smaller the corresponding data download switching identifier is, and the earlier it is accessed by the client. The number of download retries for the client can be shortened.

Further, the manner of determining the weight order is not limited in the embodiment, and the manner of manual setting and/or self-setting by the server side may be adopted. At this time, based on different weight order determination methods, it is set that this step specifically includes at least one of the following schemes:

Solution 1: The server periodically obtains the weight order of the domain name address information, and updates the domain name configuration information according to the weight order.

Specifically, the weight order of each domain name address information can be manually set by the technical personnel on the server side, wherein the corresponding authority can be set, and only the technical personnel who satisfy the authority can set the weight order. After that, the data download switching identifier corresponding to the domain name address information is updated according to the weight sequence, that is, the updated domain name configuration information is obtained.

Scheme 2: The server determines the weight order of the domain name address information through the fault notification information corresponding to the domain name address information, and updates the domain name configuration information according to the weight order.

Exemplarily, when an edge server, a source server, or other devices storing the data in the content distribution network that stores the data fails, failure notification information is generated and sent to the server. The fault notification information may include content such as identity information of the faulty device. Afterwards, the server side shifts the weight order of the domain name address information corresponding to the faulty device backward according to the fault notification information, so that the weight order corresponds to a larger data download switching identifier. Alternatively, the server side collects statistics on fault notification information within a set period of time, so as to update the weight order according to the number of faults of each device, and place the domain name address information corresponding to the device with a smaller number of faults in the front in the weight order. After that, the data download switching identifier corresponding to the domain name address information is updated according to the weight sequence, that is, the updated domain name configuration information is obtained. Understandably, the minimum number of failures can be 0

Solution 3: The server determines the weight order of the corresponding domain name address information through the download failure information returned by the client, and updates the domain name configuration information according to the weight order.

Specifically, after the client fails to download according to the download address information, it will generate download failure information and return it to the server, or return it to the corresponding storage (such as big data), and then the server periodically reads the download in the storage. failure message. Wherein, the download failure information includes at least download address information. Afterwards, the server side may determine the corresponding domain name address information according to the download address information in the download failure information. Further, the server side counts the domain name address information that fails to download within a certain period of time, and then updates the weight order according to the number of download failures corresponding to each domain name address information. After that, the data download switching identifier corresponding to the domain name address information is updated according to the weight sequence, that is, the updated domain name configuration information is obtained. The number of download failures can be at least 0. It can be understood that when the number of download failures is counted, the download failure information fed back by all clients corresponding to multiple clients or servers can be used to ensure the accuracy of the number of download failures.

Typically, the server side may include multiple servers to reduce the data processing pressure of each server. For example, the server side includes a cloud storage server and a service server, wherein the cloud storage server is used to configure the download address information of the stored data, and configure the corresponding domain name address information for the download address information. The service server is used to periodically obtain the domain name address information in the cloud storage server, update the domain name configuration information, and receive the data download switching identifier sent by the client, so as to determine the domain name address information corresponding to the data download switching identifier according to the domain name configuration information, and then, The domain name address information is assembled into download address information and fed back to the client, so that the client can download.

By regularly updating the domain name configuration information, the validity of the domain name configuration information can be ensured, so that the download address information with a high download success rate is preferentially returned to the client, thereby reducing the number of download retry attempts by the client.

The data downloading method provided by this embodiment is exemplarily described below. In this embodiment, the data downloading system for executing the data downloading method includes a server end, a client end, a content distribution network, and a source server end. The source server side can be considered as a type of server included in the server side, and the source server side is cloud storage. At the same time, the server side also includes cloud storage server and business server. FIG. 3 is a block diagram of a data flow provided by Embodiment 2 of the present application, which is a data processing flow of this example, with reference to FIG. 3 :

Specifically, when the Client (client) determines that it starts to download data, it sets the downloadPollingNo (data download switching identifier) to an initial value of 0. After that, it is determined whether the current download is a download retry, and if it is not a download retry, downloadPollingNo is placed in the request header of the download request. If the download is retried, downloadPollingNo+1 will be added and a new downloadPollingNo will be obtained. After that, place downloadPollingNo in the request header of the download request. The client sends the download request to the Business Server (business server). After that, Business Server obtains downloadPollingNo in the request header, and determines the domain name address information corresponding to downloadPollingNo based on the domain name configuration information, then assembles the domain name address information to obtain the download address information, and returns the download address information to the client. Typically, the Cloud Storage Server (cloud storage server) can be configured with domain name address information corresponding to the download address information. The Business Server can periodically synchronize the domain name address information in the Cloud Storage Server and generate domain name configuration information.

The client determines whether the download address information can be accessed. If not, it is determined that the download process ends. If yes, download the data through the download address information. At this point, the client accesses the CDN through the download address information to obtain the corresponding data. The CDN determines whether the corresponding data exists in its own cache, and if so, returns the data to the Client. After that, the Client determines whether the download is successful. If the download is successful, the download process is ended. If the download is unsuccessful, the download is retried, and the process of judging whether the current download is a download retry is executed.

If the CDN determines that there is no corresponding data in its own cache, it will go back to the corresponding Cloud Storage (origin server) to pull the data, and then Cloud Storage will determine whether it has stored the corresponding data. If the corresponding data is stored, the data is returned to the CDN, and the CDN returns the data to the Client. After that, the Client determines whether the download is successful. If the download is successful, the download process is ended. If the download is unsuccessful, the download is retried, and the process of judging whether the current download is a download retry is executed.

If Cloud Storage determines that it does not store the corresponding data, it pulls the data through the image file and returns it to the CDN, so that the CDN can return the data to the Client. After that, the Client determines whether the download is successful. If the download is successful, the download process is ended. If the download is unsuccessful, the download is retried, and the process of judging whether the current download is a download retry is executed. Through the above process, the success rate of data download can be improved.

Embodiment 3

FIG. 4 is a schematic structural diagram of a data downloading apparatus according to Embodiment 3 of the present application. Referring to FIG. 4 , the data downloading apparatus provided in this embodiment includes: an identification setting module 301 , an address obtaining module 302 and an address returning module 303 .
