[0041] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0043] The acquisition, storage, use, and processing of data in this application's technical solution comply with relevant national laws and regulations.

[0044] The current object storage service authentication method involves querying user permissions when downloading files, either by saving user information or through a callback interface. However, this authentication method, which saves user information in the object storage service, makes the object storage service dependent on applications, making it unsuitable for other applications as a public service. This also increases application development complexity and costs. The callback interface method, which queries user download permissions, requires the object storage service to request the application and wait for a response. This results in lengthy service response times, which degrades the performance of the object storage service.

[0045] In order to solve the problems of the prior art, the embodiments of the present application provide a file downloading method, device, equipment, medium and product.

[0046] The file downloading method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0047] Figure 1 This is a flowchart of the file download process in the file download method provided in the embodiment of the present application.

[0048] like Figure 1 As shown, the application terminal device involved in the embodiment of the present application may include an application client, and the application client may be an application service page. The object storage cloud service system may be a public service system that provides file transfer for applications, and a cache database is provided in the object storage cloud service system. The application server may be a server corresponding to the application terminal device. The object storage cloud service system receives a cache request for a user downloadable file list sent by the application server, and in response to the cache request, associates the user identifier and the user downloadable file list in the cache request and stores it in the cache database. The object storage cloud service system receives a first file download request for a target file sent by the application terminal device, and in response to the first file download request, obtains the user downloadable file list from the cache database according to the user identifier, and in the case where the user downloadable file list includes the target file identifier, obtains the target file, and sends the target file to the application terminal device.

[0049] Figure 2 This is a flowchart of a file download method provided by an embodiment of the first aspect of the present application. The file download method can be applied to an object storage cloud service system, in which a cache database is provided.

[0050] like Figure 2 As shown, the file downloading method may specifically include the following steps:

[0051] S210: Receive a cache request for a user downloadable file list sent by an application server, where the cache request includes a user identifier and the user downloadable file list, wherein the user downloadable file list includes a file identifier of at least one downloadable file corresponding to the user identifier;

[0052] S220 , in response to the cache request, associating the user identifier with the user's downloadable file list and storing it in the cache database;

[0053] S230: Receive a first file download request for a target file sent by an application terminal device, where the first file download request includes a user identifier and a target file identifier corresponding to the target file;

[0054] S240: In response to the first file download request, obtain a list of user downloadable files from a cache database according to the user identifier;

[0055] S250: When the user downloadable file list includes the target file identifier, the target file is acquired and sent to the application terminal device.

[0056] Therefore, the user identifier and the user's downloadable file list are associated and stored in a cache database set up in the object storage cloud service system. When the user downloads the target file, the object storage cloud service system queries the user's downloadable file list cached in the cache database based on the user identifier. If the user's downloadable file list contains the target file identifier, the obtained target file is sent to the application terminal device. When the user downloads a file, the cache database is used to cache the user's downloadable file list, which is simple to transform and has low application development complexity, greatly saving costs. In addition, the cache database is used to authenticate file downloads based on the user identifier. After determining that the user has download permission, the target file is provided to the user. File download authentication is separated from file downloading, reducing calls to the application backend, reducing service response time, and improving service performance.

[0057] The specific implementation methods of the above steps are introduced below.

[0058] In some embodiments, in S210, the user identifier included in the cache request may be, for example, a number identifier corresponding to the user assigned by the application server. The user downloadable list may include a file identifier corresponding to at least one file that the user has permission to download, wherein the file identifier corresponds to the user identifier and may be an identifiable identifier corresponding to the file, such as a file name.

[0059] In some embodiments, in S220, the cache database involved in the embodiments of the present application may be a storage system, for example, a redis storage system.

[0060] In some embodiments, the above S220 may specifically include:

[0061] Get the downloadable file according to the file identifier;

[0062] The user ID, the user downloadable file list and the downloadable files are associated and stored in a cache database.

[0063] In some embodiments, the object storage cloud service system caches the downloadable file corresponding to the file identifier of at least one downloadable file in the user's downloadable file list based on the file identifier of the file, and then associates the cached downloadable file with the user identifier and the user's downloadable file list and stores it in the cache database.

[0064] As an example, after the object storage cloud service system receives a cache request for a user's downloadable file list sent by an application server, it caches and downloads the user's downloadable files based on the user ID in the cache request and the file ID of the downloadable file in the user's downloadable file list. After the user's downloadable files are cached, a collection interface can be set in the cache database, and the user ID, the user's downloadable file list and the user's downloadable files can be associated and stored according to the set collection interface.

[0065] Thus, the user identification, the user's downloadable file list, and the downloadable files are associated through the cache database, and the user can be authenticated based on the user identification when the user downloads the file.

[0066] In some embodiments, to increase the security of user file downloads, the cache request also includes a validity period corresponding to the user identifier. Based on this, the method may further include:

[0067] According to the validity period corresponding to the user ID, the validity period corresponding to the user's downloadable file list is set in the cache database;

[0068] When the system time reaches the valid time, the list of user downloadable files is deleted from the cache database.

[0069] In some embodiments, the validity period corresponding to the user identifier may be, for example, the validity period set by the application server for the user identifier.

[0070] As an example, in the cache data, the user downloadable file list can be set according to the valid time of the user identifier. After the system time reaches the set valid time, the cache database will delete the cached user downloadable file list.

[0071] Therefore, the cache database sets an effective time for the user's downloadable file list, and after the set effective time is reached, the user's downloadable file list is deleted from the cache database, thereby increasing the security of the user's downloading of files.

[0072] Based on this, in some embodiments, after the above S220, the method may further include:

[0073] Send feedback information to the application server, where the feedback information includes a cache success flag or a cache failure flag.

[0074] In some embodiments, the feedback information involved in the embodiments of the present application may be, for example, feedback on cache status information of a cache database in response to a cache request, and the cache status of the cache database may be success or failure.

[0075] As an example, after the object storage cloud service system caches data in response to a cache request based on the cache database, it will send feedback information to the application server based on the cache database's cache status. If the cache database's cache status is successful, the system will send feedback information including a cache success flag to the application server; if the cache database's cache status is failed, the system will send feedback information including a cache failure flag to the application server.

[0076] Therefore, by sending feedback information to the application server, the application server can feed back the cache status to the application terminal device according to the cache status information in the feedback information.

[0077] In some embodiments, in S230, the first file download request involved in the embodiments of the present application may be a file download request for a target file sent by the application terminal device to the object storage cloud service system after receiving feedback information including a cache success flag. The target file may, for example, be a file corresponding to a file identifier of a downloadable file in the user's downloadable file list. The target file identifier corresponding to the target file may, for example, be an identifiable identifier corresponding to the target file, such as the file name of the target file.

[0078] In some embodiments, in S240, the object storage cloud service system responds to the first file download request, queries the cache database according to the user identifier, obtains the user downloadable file list from the cache database, and checks whether the file identifier corresponding to the target file is in the user downloadable file list.

[0079] In some embodiments, in S250, the object storage cloud service system queries the cache database according to the user identifier, checks that the user's downloadable file list includes the target file identifier, obtains the target file, and sends the target file to the application terminal device.

[0080] In order to improve the service performance of the object storage cloud service system, the embodiment of the present application also provides another embodiment of the file download method. Figure 3 As shown, the method may further include:

[0081] S310: Receive a cache request for a user downloadable file list sent by an application server, wherein the cache request includes a user identifier and the user downloadable file list, wherein the user downloadable file list includes a file identifier of at least one downloadable file corresponding to the user identifier;

[0082] S320: In response to the cache request, associate the user identifier with the user downloadable file list and store them in the cache database;

[0083] S330: Receive a first file download request for a target file sent by an application terminal device, where the first file download request includes the user identifier and a target file identifier corresponding to the target file;

[0084] S340: In response to the first file download request, obtain the user downloadable file list from the cache database according to the user identifier;

[0085] S350: If the target file identifier is not included in the user downloadable file list, reject the first file download request;

[0086] S360: Record the cumulative number of download failures corresponding to the user ID.

[0087] The above S310 - S330 are the same as the above S210 - S230 and will not be described in detail here for the sake of brevity.

[0088] In some embodiments, in S350, the object storage cloud service system queries the cache database according to the user identifier and checks that the user's downloadable file list does not include the target file identifier, and then rejects the user's download request.

[0089] In some embodiments, in S360, a cumulative download failure coefficient corresponding to the user identifier is set in the object storage cloud service system. After the user requests to download and is denied downloading a file, the object storage cloud service system will record the number of download failures corresponding to the user identifier plus 1 to obtain the cumulative number of download failures.

[0090] Based on this, in some embodiments, the above S340 may specifically include:

[0091] Get the cumulative number of download failures corresponding to the user ID;

[0092] When the cumulative number of download failures does not exceed a preset threshold, a list of downloadable files for the user is obtained from the cache database according to the user ID;

[0093] When the cumulative number of download failures exceeds a preset threshold, the file download request corresponding to the user identifier is rejected within a preset time period.

[0094] In some embodiments, the preset threshold involved in the embodiments of the present application can be, for example, a preset maximum number of cumulative download failures, and the preset duration can be, for example, the duration during which the user is no longer allowed to download files after the user's cumulative download failures exceed the preset threshold.

[0095] As an example, in response to a first file download request sent by an application terminal device, the object storage cloud service system first obtains the cumulative number of download failures corresponding to the user ID based on the user ID. If the cumulative number of download failures does not exceed a preset threshold, the system obtains a list of downloadable files for the user from a cache database and queries the user for download permissions. If the cumulative number of download failures exceeds the preset threshold, the system rejects the file download request corresponding to the user ID for a certain period of time based on a preset duration.

[0096] Therefore, the list of downloadable files in the cache database is queried through the user ID. If the target file ID is not included in the user's downloadable file list, the file download request is rejected, and the cumulative number of download failures corresponding to the user ID is recorded. The user's download request is restricted based on whether the cumulative number of download failures exceeds the preset threshold, providing security for user downloads and effectively reducing users' malicious downloading of files.

[0097] Figure 4 This is a flowchart of a file download method provided in the second embodiment of the present application. The file download method can be applied to an application server.

[0098] like Figure 4 As shown, the file downloading method may specifically include the following steps:

[0099] S410: Receive a second file download request sent by an application terminal device, where the second file download request includes a user identifier of a target user and a file identifier corresponding to at least one file, where the target user is a user logged in to the application terminal device;

[0100] S420: In response to the second file download request, query the target user's download authority for at least one file according to the user identifier to obtain a query result;

[0101] S430: If the query result indicates that the target user has download permission, generate a list of user-downloadable files based on the file identifier corresponding to at least one file;

[0102] S440: Send a cache request for the user's downloadable file list to the object storage cloud service system.

[0103] Thus, by receiving a second file download request sent by an application terminal, the target user logged in at the application terminal is queried for file download permissions based on the user identifier in the second file download request and the file identifier corresponding to at least one file. If the query result indicates that the target user has download permissions, a user downloadable file list is generated based on the file identifier, and a cache request for the user downloadable file list is sent to the object storage cloud service system. Thus, when a user downloads a file, the file download permissions are queried for the user based on the user identifier, and if the user has permissions, a user downloadable file list is generated for the user. By caching the user downloadable file list in a cache database in the object storage cloud service system, the cache database is used to perform authentication when the user downloads files. This simplifies the transformation, reduces the complexity of application development, and significantly saves costs.

[0104] In some embodiments, in S410, the second file download request involved in the embodiments of the present application may be used to instruct the application server to query whether the target user has the permission to download the file based on the user identifier and the file identifier corresponding to at least one file. The target user may be a user logged in to the application terminal device.

[0105] In some embodiments, in S420, the application server responds to the second file download request and queries the target user's download permission for at least one file based on the user identifier to obtain a query result, where the query result may be that the target user has download permission or that the target user does not have download permission.

[0106] In some embodiments, in S430, if the application server finds that the user has download permission, the application server generates a list of user downloadable files based on the file identifier corresponding to at least one file. If the application server finds that the user does not have download permission, the application server fails to generate the list of user downloadable files.

[0107] In some embodiments, in S440 , after generating the user downloadable file list, the application server sends a cache request for the user downloadable file list to the object storage cloud service system.

[0108] In some embodiments, after the above S440, the method may further include:

[0109] Receive feedback information sent by the object storage cloud service system;

[0110] Send feedback information to the application terminal device.

[0111] As an example, after receiving a second file download request from an application terminal device, the application server queries the target user's download permissions based on the user identifier and the file identifier corresponding to at least one file in the second download request, and generates a user-downloadable file list based on the file download query result. Based on the generated user-downloadable file list and the user identifier, the application server sends a cache request to the object storage cloud service system. After receiving feedback information including the cache status from the object storage cloud service system, the application server sends the feedback information to the application terminal device.

[0112] When the cache status is successful, feedback information including a cache success flag is sent to the application terminal device; when the cache status is failed, feedback information including a cache failure flag is sent to the application terminal device. When the application terminal device receives the cache success flag, it sends a file download request to the object storage cloud service system; when the application terminal device receives the cache failure flag, it does not initiate a file download request.

[0113] Therefore, by sending feedback information to the application terminal device, when the application terminal device receives a cache failure flag, it does not initiate a file download request, which can reduce the call of the object storage cloud service system and improve service performance.

[0114] In order to facilitate the authentication of user file downloads, the present application embodiment also provides another embodiment of the file download method. Figure 5 As shown, before the above S410, the method may further include:

[0115] S510: Assign a user ID to the target user when the target user logs in.

[0116] Based on this, after the above S510, the method may further include:

[0117] Set the valid time corresponding to the user ID.

[0118] As an example, after the target user logs in to the application terminal, the application server allocates a user ID to the target user and sets a valid time corresponding to the user ID. During the valid time, the user downloads files based on the allocated user ID.

[0119] Therefore, by allocating a user ID to the target user when the target user logs in and setting a valid time for the user ID, it is convenient to authenticate the target user's file download based on the user ID when the target user downloads the file.

[0120] It should be noted that the application scenarios described in the above-mentioned embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Ordinary technicians in this field can know that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0141] A setting module, configured to set the valid time corresponding to the user's downloadable file list in the cache database according to the valid time corresponding to the user identifier;

[0142] The deletion module is used to delete the user's downloadable file list from the cache database when the system time reaches the valid time.

[0143] In some embodiments, the file downloading device 600 may further include:

[0144] The second sending module is configured to send feedback information to the application server after associating the user identifier with the user downloadable file list and storing it in the cache database in response to the cache request, wherein the feedback information includes a cache success flag or a cache failure flag.

[0145] Figure 7 This is a schematic diagram of the structure of a file downloading device provided in the second embodiment of the present application. The file downloading device can be applied to an application server.

[0146] like Figure 7 As shown, the file downloading device 700 may include:

[0147] The third receiving module 701 is configured to receive a second file download request sent by an application terminal device, the second file download request including a user identifier of a target user and a file identifier corresponding to at least one file, where the target user is a user logged in to the application terminal device;

[0148] The third response module 702 is configured to query the target user's download authority for at least one file according to the user identifier in response to the second file download request, and obtain a query result;

[0149] A generating module 703 is configured to generate a list of user-downloadable files based on a file identifier corresponding to at least one file when the query result indicates that the target user has download permission;

[0150] The first sending module 704 is configured to send a cache request for a list of user downloadable files to the object storage cloud service system.

[0151] In some embodiments, the file downloading device 700 may further include:

[0152] The allocation module is used to allocate a user identification to the target user when the target user logs in before receiving the second file download request sent by the application terminal device.

[0153] In some embodiments, the file downloading device 700 may further include:

[0154] The second setting module is used to set the validity period corresponding to the user identification after the user identification is allocated to the target user when the target user logs in.

[0155] In some embodiments, the file downloading device 700 may further include:

[0156] a fourth receiving module, configured to receive feedback information sent by the object storage cloud service system after sending a cache request for a list of user downloadable files to the object storage cloud service;

[0157] The third sending module is used to send feedback information to the application terminal device.

[0158] Therefore, the user identifier and the user's downloadable file list are associated and stored in a cache database set up in the object storage cloud service system. When the user downloads the target file, the object storage cloud service system queries the user's downloadable file list cached in the cache database based on the user identifier. If the user's downloadable file list contains the target file identifier, the obtained target file is sent to the application terminal device. When the user downloads a file, the cache database is used to cache the user's downloadable file list, which is simple to transform and has low application development complexity, greatly saving costs. In addition, the cache database is used to authenticate file downloads based on the user identifier. After determining that the user has download permission, the target file is provided to the user. File download authentication is separated from file downloading, reducing calls to the application backend, reducing service response time, and improving service performance.
