[0029] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. For the purpose of clarity, the description is divided into the following sections: technical scheme, advantages, and specific embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present application, and are not intended to limit the present application. The present application can be implemented without some of the specific details described below. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0030] It should be noted that, in this document, the terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between such entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0031] In order to improve the operation efficiency of housing accumulation fund management, the housing accumulation fund management operation system is optimized by using digital technology, the accurate and efficient business audit and the rapid and safe fund settlement are realized, and the front-end application of supervision is initiated by the Housing and Construction Department. The front-end application of supervision has functions such as instant messaging, data report, operation and maintenance work order and message push. However, with the expansion of the scale of the supervision mobile terminal users, the number of installed supervision front-end applications also increases. When users use the instant messaging and operation and maintenance work order functions of the front-end application of supervision, if a large file (such as a file exceeding 30M) is sent, the application in the back-end server needs to process a large number of request concurrent file downloads, which causes the application memory usage rate to be high, and even causes memory overflow, application downtime and other situations.

[0032] In the technical scheme of the present application, the acquisition, storage, use, processing and other aspects of data comply with the relevant provisions of national laws and regulations. It should be noted that in the embodiments of the present application, some industry existing schemes of software, components, models and the like may be mentioned, which should be considered as exemplary, and the purpose is only to illustrate the feasibility of the implementation of the technical scheme of the present application, but it does not mean that the applicant has or will necessarily use the scheme.

[0033] To solve the problems in the prior art, the embodiments of the present application provide a file downloading method, device, equipment, storage medium and program product. First, the file downloading system provided by the embodiments of the present application is introduced.

[0034] Figure 1 An architecture diagram of a file downloading system to which the embodiments of the present application are applicable is shown. As shown in the figure, the file downloading system 100 can include a mobile terminal 101 and a backend server 102. Figure 1

[0035] The mobile terminal 101 can be a front-end device used by a user to achieve accurate and efficient business auditing and fund settlement, such as a personal computer, a mobile phone, a tablet and the like. The mobile terminal can include a construction supervision front-end application, which has functions of instant messaging, data report, operation and maintenance work order and message pushing, and can send a download request for downloading a large file to the backend server.

[0036] The backend server 102 can be a backend device used to achieve accurate and efficient business auditing and fund settlement, such as a cloud server. The backend server can process a download request generated when the instant messaging and operation and maintenance work order functions of the construction supervision front-end application in the mobile terminal are processed, and send a download file to the mobile terminal.

[0037] The backend server 102 can specifically include an application object 1021 and a file sub-server 1022, and the application object 1021 and the file sub-server 1022 are connected through a communication channel. The application object, i.e. a software application program, is a kind of program in a computer system, which is designed to help users perform specific tasks or meet specific needs. In the embodiments of the present application, the application object can refer to a software application program written in Java language. The file sub-server is a simple file server built in the backend server by using the nginx application, and a communication channel is built between the Java application and the file sub-server, so that the application object and the file sub-server can use the communication channel for file downloading. In the embodiments of the present application, since the nginx application is convenient and fast to build, occupies few resources, and is suitable for building a simple file server with low cost, the operation cost can be reduced.

[0038] The mobile terminal 101 and the backend server 102 are connected in communication. Specifically, Ethernet or wireless network connection mode can be used for communication. Of course, the communication mode is not limited to this, but can also be other network connection communication modes, which are not limited here.

[0039] The file downloading method provided by the embodiments of the present application is introduced as follows.

[0040] Figure 2 ​A flowchart of a file downloading method provided by an embodiment of the present application is shown. Optionally, the method of the embodiment of the present application can be applied to the mobile terminal and the backend server shown above. Figure 1 As shown in FIG. 2, a file downloading method 200 can include the following steps S201-S205. Figure 2 As shown in FIG. 2, a file downloading method 200 can include the following steps S201-S205.

[0041] S201, the mobile terminal sends a download request to an application object in the backend server, the download request being used to request downloading a target file, the target file being stored in a file sub-server,

[0042] S202, the application object receives the download request sent by the mobile terminal.

[0043] S203, the application object sends the download request to the file sub-server through a communication channel.

[0044] S204, the file sub-server sends the target file to the mobile terminal in response to the download request.

[0045] S205, the mobile terminal receives the target file sent by the file sub-server.

[0046] The file downloading method of the embodiment of the present application can be used to send a download request to an application object in a backend server by a mobile terminal, and then the application object sends the download request to a file sub-server in the backend server through a communication channel. In this way, the file sub-server can send a target file to the mobile terminal in response to the download request. Thus, in the embodiment of the present application, a file sub-server is arranged in the backend server, and the file sub-server is used to send files to the mobile terminal, so that part of the processing request of the application object during file downloading can be shared, thereby reducing the memory usage of the application object.

[0047] In S201, the download request can be used to request downloading a target file. The target file is stored in the file sub-server. For example, the target file is a file whose size exceeds 30 megabytes in the file sub-server.

[0048] The mobile terminal sends the download request to the application object in the backend server, for example, the mobile terminal can send the download request to the application object in the backend server through wireless communication.

[0049] In S202, the application object receives the download request sent by the mobile terminal, for example, the application object can receive the download request sent by the mobile terminal through wireless communication.

[0050] In S203, the communication channel, for example, can be a file downloading channel constructed between the application object and the file sub-server by using nginx application.

[0051] In S204, the sending of the target file to the mobile terminal can be exemplarily direct sending of the target file to the mobile terminal, or sending of the target file to the mobile terminal at a preset download speed.

[0052] In S205, the mobile terminal receives the target file sent by the file sub-server, which can be exemplarily direct receiving of the target file sent by the file sub-server, or receiving of the target file sent by the file sub-server at a preset download speed.

[0053] As an implementation manner of the present application, to ensure that the target file is downloadable, before S201, the method can further include:

[0054] The mobile terminal receives a target operation of clicking to download the target file in a display operation interface of the mobile terminal by a user;

[0055] The mobile terminal sends a query request to the application object in response to the target operation, the query request being used to query whether the target file is downloadable;

[0056] The application object queries queue state information of a download queue in the application object in response to the query request, the queue state information being used to indicate whether the download queue is full;

[0057] The application object generates a download flag according to the queue state information, the download flag being used to represent whether the target file is downloadable;

[0058] The application object sends the download flag to the mobile terminal;

[0059] S201 can specifically include:

[0060] The mobile terminal sends a download request to the application object in the backend server in a case where the download flag represents that the target file is downloadable.

[0061] The target operation can be an operation of clicking to download the target file in a display operation interface of the mobile terminal by a user.

[0062] The query request can be used to query whether the target file is downloadable.

[0063] The queue state information can be used to indicate whether the download queue is full.

[0064] The download flag can be used to represent whether the target file is downloadable. For example, the download flag includes a first flag and a second flag, wherein the first flag is used to represent that the target file is downloadable, and the second flag is used to represent that the target file is not downloadable.

[0065] The generating of the download flag according to the queue state information can specifically include: in a case where the queue state information indicates that the download queue is not full, adding the download request to the download queue and generating a first flag, the first flag being used to represent that the target file is downloadable; in a case where the queue state information indicates that the download queue is full, not adding the download request to the download queue and generating a second flag, the second flag being used to represent that the target file is not downloadable; and the download flag including the first flag and the second flag.

[0066] In some embodiments, the mobile terminal polls for a new download flag in a case where the download flag represents that the target file is not downloadable, until the new download flag represents that the target file is downloadable.

[0067] In the embodiments of the present application, the mobile terminal queries the queue state information of the download queue in the application object by sending a query request to the application object, and sends the download flag representing whether the target file is downloadable to the mobile terminal, so that the mobile terminal sends a download request to the application object in the backend server only in a case where the download flag represents that the target file is downloadable, thereby ensuring that the target file is downloadable.

[0068] As another implementation method of the present application, in order to enhance the reliability of the download flag, the query request can include user authentication information, and before the application object sends the download flag to the mobile terminal, the method can further include:

[0069] The application object responds to the query request, authenticates the user authentication information, and generates an authentication result, the authentication result being used to indicate whether the user authentication information is authenticated.

[0070] The application object sends the download flag to the mobile terminal, specifically including:

[0071] The application object sends the download flag to the mobile terminal in a case where the authentication result indicates that the user authentication information is authenticated.

[0072] The user authentication information can be data and credentials for verifying the identity of a user, for example, a username, a password, biometric information, etc.

[0073] The authentication of the user authentication information and the generation of the authentication result can be, for example, comparing and authenticating a username and a password input by the user with a password stored in a database to generate the authentication result.

[0074] The authentication result can be used to indicate whether the user authentication information is authenticated.

[0075] In the embodiments of the present application, the user authentication information is authenticated to generate an authentication result, and the application object sends the download flag to the mobile terminal only when the authentication result indicates that the user authentication information is authenticated, so as to enhance the reliability of the download flag.

[0076] In some embodiments, the application object sends the download flag to the mobile terminal when the authentication result indicates that the user authentication information is authenticated, and specifically can include:

[0077] The application object generates a first download token when the authentication result indicates that the user authentication information is authenticated.

[0078] The application object sends the first download token and the download flag to the mobile terminal.

[0079] The S202 can specifically include:

[0080] The application object receives a download request sent by the mobile terminal, and the download request includes a second download token.

[0081] The application object verifies the second download token according to the first download token to generate a verification result, and the verification result is used to indicate whether the second download token is consistent with the first download token.

[0082] The S203 can specifically include:

[0083] The application object sends the download request to the file sub-server through the communication channel when the verification result indicates that the second download token is consistent with the first download token.

[0084] The first download token can be an authorization credential with a validity period, which allows the user to access a specific system or service within a certain time.

[0085] The download request can include the second download token, and theoretically, the second download token is consistent with the first download token.

[0086] The verification result can be used to indicate whether the second download token is consistent with the first download token.

[0087] In the embodiments of the present application, the application object verifies whether the second download token in the download request is consistent with the first download token generated when the authentication result indicates that the user authentication information is authenticated, so as to enhance the security and reliability of the file download.

[0088] In some embodiments, the S204 can specifically include:

[0089] The file sub-server sends the target file to the mobile terminal according to a preset download speed in response to the download request.

[0090] The S205 can specifically include:

[0091] The mobile terminal receives the target file sent by the file sub-server at a preset download speed.

[0092] The preset download speed may, for example, be a parameter value configured by the nginx application to limit the user download speed.

[0093] In the embodiments of the present application, the target file is sent to the mobile terminal at a preset download speed to limit the user download speed, which can effectively reduce the bandwidth proportion occupied during downloading, thereby further reducing the memory usage of the application object and improving the availability of non-download services.

[0094] To facilitate the understanding of the file download method in the embodiments of the present application, the actual application process of the file download method is described as follows:

[0095] In the present application, a simple file server (i.e. the above-mentioned file sub-server) can be constructed by using the nginx application, and a file download channel (i.e. the above-mentioned communication channel) can be constructed between the Java application (i.e. the above-mentioned application object) and the file server, to solve the problem of high memory occupation of the java virtual machine when downloading large files (i.e. the above-mentioned target file) concurrently. At the same time, since the nginx application is easy and fast to build and occupies less resources, it is suitable for building a simple file server with low cost.

[0096] As shown in Figure 3 The embodiments of the present application can include the following steps:

[0097] 1. The user clicks the download button on the front-end (i.e. the above-mentioned mobile terminal) interface to request to send the user authentication information to the gateway (equivalent to the above-mentioned application object), and query whether the current request can download the file (equivalent to the above-mentioned query request).

[0098] 2. After the gateway authenticates the user identity, a temporary download token (i.e. the above-mentioned first download token) is generated. It is judged whether the download queue is full. If not, the request is added to the download queue, and a downloadable flag and a download token are returned. If it is full, it is not added to the download queue, and a non-downloadable flag and a download token are returned.

[0099] 3. The front end judges according to the return of the downloadable flag. If it is downloadable, the download request is sent to the gateway with the download token.

[0100] 4. The gateway checks and verifies the validity of the download token. If valid, it will request the nginx file server (equivalent to the file sub-server mentioned above) through the established channel to download the file (equivalent to the target file mentioned above).

[0101] 5. The nginx file server will provide a speed-limited download service based on the configured download speed and return the file to the front end.

[0102] 6. If the gateway verifies that the download token is invalid, it returns an invalid error message to the front end. The front end does not prompt the user and will re-initiate the download request, returning to step 1.

[0103] 7. The front-end determines whether the download is possible based on the returned download flag. If the download is not possible, the front-end will put the download task in the background and periodically poll step 1.

[0104] In this embodiment, by configuring nginx rate limiting and speed control strategies, user download speeds are restricted, Java application memory usage is reduced, and system reliability is improved. Simultaneously, since nginx consumes few resources, operating costs are lowered. Rate limiting and speed control can effectively reduce the proportion of bandwidth used during downloads, improving the availability of non-download services.
