In the related art, the provided data is downloaded in the following manner: the host provides the participant with the website (or link) of the data, and the participant downloads the corresponding data on the terminal through the website.

Based on the research, the present disclosure provides a file downloading method, where a first terminal may generate unique identity information for a downloading task and display a corresponding information code in a process of loading a file downloading page based on a website provided by an event host, a second terminal may obtain the unique identity information through the information code and send the unique identity information to a server, and the server may establish a correspondence between the unique identity information and a downloading address of a target file, so that the first terminal may determine the corresponding downloading address at the server based on the unique identity information and obtain the target file through the downloading address. In the process of acquiring the target file, the first terminal, the second terminal and the server do not need to display the download address of the target file in a plaintext form, so that the difficulty of acquiring the download address in an unconventional way is improved, the risk of leakage of the download website is reduced, the enthusiasm of people for participating in online activities for acquiring the target file is promoted, and the online activities are ensured to achieve the expected effect to a greater extent.

To facilitate understanding of the present embodiment, a detailed description will be first given of a file downloading method disclosed in the embodiments of the present disclosure. The execution main body of the file downloading method provided by the embodiment of the disclosure is a file downloading system. Referring to fig. 1, an architecture diagram of a file downloading system provided in an embodiment of the present disclosure is shown, where the file downloading system includes a first terminal, a second terminal, and a server, and the first terminal and the second terminal are respectively in communication connection with the server.

The first terminal and the second terminal are typically computer terminals with certain computing capabilities, the computer terminals for example comprising: a terminal device, which may be a User Equipment (UE), a mobile terminal, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld terminal, a computing terminal, a vehicle-mounted terminal, a wearable terminal, or a server or other processing terminal. In some possible implementations, the file download method may be implemented by a processor calling computer readable instructions stored in a memory.

Referring to fig. 2, a flowchart of a file downloading method provided in the embodiment of the present disclosure is shown, where the method includes steps S210 to S270, where:

s210: and the first terminal generates unique identity information aiming at the downloading task in the process of loading the file downloading page.

The unique identity information may be a random sequence, such as a random number sequence, a random letter sequence, or a mixture of both, and the random sequence is unique. Of course, the unique identity information may be other information having uniqueness. When the first terminal loads the file and executes the download page, the first terminal can call an authentication information generation function and generate unique identity information based on the authentication information generation function.

It is understood that the first terminal may load the file download page based on a website, and taking a scene that the user participates in the online activity as an example, the host of the online activity may provide the user with a website, the user inputs the website into the browser of the first terminal, and the first terminal loads the file download page based on the website.

In an alternative embodiment, a first website for loading the file download page may be acquired at the server by the second terminal, the first terminal loads the file download page based on the first website acquired at the server by the second terminal, calls the authentication information generation function in the process of loading the file download page, and generates unique identity information for the download task based on the authentication information generation function.

Taking the unique identity information as a digital sequence as an example, the first terminal may call a random number generation function in the process of loading the file download page, generate a random number sequence based on the random number generation function, and use the random number sequence as the unique identity information.

S220: and the first terminal acquires the information code of the unique identity information and displays the information code.

The information code may be a bar code, a two-dimensional code, a three-dimensional code, or the like, and it can be understood that the other device may acquire the unique identity information corresponding to the information code by scanning the information code displayed by the first terminal.

Alternatively, the first terminal may call an information code generating function, and generate an information code of the unique identity information based on the information code generating function.

Optionally, the first terminal may send the unique identity information to the server, the server generates an information code of the unique identity information, and returns the information code to the first terminal, and the first terminal receives and displays the information code generated according to the unique identity information and returned by the server. It is to be understood that the server may generate the information code of the unique identity information based on the information code generating function.

S230: and the second terminal obtains the unique identity information aiming at the downloading task through the information code displayed by the first terminal.

As described above, the information code may be a barcode, a two-dimensional code, a three-dimensional code, or the like, and it can be understood that the second terminal may acquire the unique identity information corresponding to the information code by scanning the information code displayed by the first terminal.

Under the condition that the first terminal and the second terminal do not need communication connection, the second terminal can obtain the unique identity information in a mode of scanning the information code, so that the requirement on the first terminal is reduced, and an application program capable of communicating with the second terminal does not need to be installed on the first terminal, so that a user can select one first terminal to download the target file according to the requirement.

The second terminal can respond to the code scanning operation of the user, and the code scanning function of the second terminal is triggered to scan the information code displayed by the first terminal. For example, the second terminal may run an application for participating in an online activity, a code scanning control may be displayed on a page of the application, and when it is detected that the user clicks the code scanning control, a code scanning function of the second terminal may be triggered. The application of the online activity can be an independently developed application, and can also be an application developed based on other instant messaging applications, such as a public program and an applet developed based on WeChat; a program or applet based on a baccarat pay treasure or the like.

Taking a public number program developed based on the WeChat as an example, the public number program may include a plurality of pages, a code scanning control is displayed on one page, when it is detected that a user clicks the code scanning control, a code scanning function of the WeChat is called to display a code scanning frame, and the user may align a camera of the second terminal with an information code displayed by the first terminal at the moment, so that an image of the information code is located in the code scanning frame, and the second terminal scans the information code to acquire unique identity information corresponding to the information code.

In an optional implementation manner, before the second terminal obtains the unique identity information for the downloading task through the information code displayed by the first terminal, the second terminal may obtain a first website for loading the file downloading page at the server, so that the first terminal loads the file downloading page based on the first website. Specifically, after determining that the user completes the preset task, the second terminal may send a first request for obtaining the first website to the server in response to an operation of downloading the target file by the user, and then receive the first website returned by the server in response to the first request.

Taking a scene that the user participates in the online activity as an example, the user downloads and runs the application for participating in the online activity through the first terminal, and the preset task is completed based on the application. These tasks may be at least one of: completing registration on the application, recommending a link to the friend to download the application, joining a specified chat group based on an interface provided by the application, purchasing a specified item based on the application, and the like. For example, the application for participating in the online activity is a public program developed based on WeChat, and the preset task may specifically be: paying attention to the public number, joining a specified WeChat chat group based on an interface provided by the public number interface, posting a link to the public number to a circle of friends, purchasing a specified item based on a shopping page of the public number, and the like.

As described above, the second terminal may run an application for participating in an online activity, and the public program may include a plurality of pages, taking the application as a public program developed based on the WeChat as an example. The second terminal may send a first request for acquiring a first website to the server when detecting that the user clicks a download control corresponding to the file displayed on the page after determining that the user completes a preset task, and then receive the first website returned by the server in response to the first request.

S240: the second terminal sends the unique identity information to the server.

The unique identity information sent by the second terminal may be used to establish a corresponding relationship with the target file, where the target file is a file that the user desires to download. And after the corresponding relation between the unique identity information and the target file is established, the first terminal acquires the target file at the server according to the unique identity information.

After the second terminal obtains the unique identity information through the information code, the unique identity information can be immediately sent to the server, other information can be continuously obtained, and the unique identity information and the other information are sent to the server together.

In an optional implementation manner, after obtaining the unique identity information through the information code, the second terminal obtains the identification information of the target file at the preset server, and sends the identification information of the target file and the unique identity information to the server.

The preset server may be the server shown in fig. 1, or may be another server other than the server shown in fig. 1. Taking a scene in which the user participates in the online activity as an example, the user downloads and runs the application for participating in the online activity through the first terminal. In one scenario, the server shown in fig. 1 may be used for both maintaining applications and providing a download service of the target file, where the server stores identification information of the target file, and the second terminal may obtain the identification information of the target file at the server. In one scenario, the server shown in fig. 1 is used to provide a download service of the target file, and other servers than the server shown in fig. 1 are used to maintain the application, and the other servers store identification information of the target file, and the second terminal may obtain the identification information of the target file at the other servers.

Here, the identification information of the target file may be a name or a number of the target file, or may be other information capable of representing the target file, the identification information of the target file has a corresponding relationship with the download address of the target file, and in the subsequent step, the server may determine the download address of the target file according to the identification information of the target file.

In an optional implementation manner, after obtaining the unique identity information through the information code, the second terminal obtains the identity information of the user at a preset server, and sends the identity information of the user and the unique identity information to the server.

The preset server may be the server shown in fig. 1, or may be another server other than the server shown in fig. 1.

Taking a scene in which the user participates in the online activity as an example, the user downloads and runs the application for participating in the online activity through the first terminal. In one scenario, the server shown in fig. 1 may be used for both maintaining an application and providing a download service of a target file, where the server stores the identity information of a user, and the second terminal may obtain the identity information of the user at the server. In one scenario, the server shown in fig. 1 is used to provide a download service of the target file, and other servers than the server shown in fig. 1 are used to maintain the application, and the other servers store the identity information of the user, and the second terminal may obtain the identity information of the user at the other servers.

Here, the identity information of the user may be an account number or a user name registered in the application, or may be other information that can represent the identity of the user. In the subsequent step, the server can determine whether the user has the downloading authority according to the identity information of the user.

In an optional implementation manner, after obtaining the unique identity information through the information code, the second terminal obtains the identification information of the target file and the identity information of the user at the preset server, and sends the identification information of the target file, the identity information of the user and the unique identity information to the server. Here, the description of the identification information of the target file and the identity information of the user may refer to the foregoing contents, and will not be described herein again.

S250: and the server receives the unique identity information aiming at the downloading task sent by the second terminal.

The server can receive other information sent by the second terminal besides the unique identity information sent by the second terminal.

In an alternative embodiment, the server may receive the identification information of the target file and the unique identity information for the download task, which are sent by the second terminal.

The identification information of the target file may be the name or number of the target file, or may be other information capable of characterizing the target file. The identification information of the target file has a corresponding relation with the download address of the target file, and in the subsequent steps, the server can determine the download address of the target file according to the identification information of the target file.

In an alternative embodiment, the server receives the identity information of the user and the unique identity information for the download task, which can be sent by the second terminal.

The identity information of the user may be an account number or a user name registered in an application for participating in an online activity, or may be other information capable of characterizing the identity of the user. In the subsequent step, the server can determine whether the user has the downloading authority according to the identity information of the user.

In an alternative embodiment, the server receives the identification information of the target file, the identity information of the user and the unique identity information, which can be sent by the second terminal. Here, the description of the identification information of the target file and the identity information of the user may refer to the foregoing contents, and will not be described herein again.

S260: the server establishes a corresponding relation between the unique identity information and the download address of the target file.

In this step, the server may store the unique identity information and the download address of the target file in a preset database in an associated manner, thereby establishing a correspondence between the unique identity information and the download address of the target file.

Taking the preset database as Redis as an example, it should be noted herein that Redis provided in the embodiment of the present disclosure is a key-value storage system. In Redis, the unique identity information is used as a key value, and the download address of the target file is used as a value corresponding to the key value, so that the corresponding relation between the unique identity information and the download address of the target file is established.

As described above, the server receives the identification information of the target file that can be transmitted by the second terminal and the unique identification information for the download task. In an optional implementation manner, the server may determine a download address of the target file according to the identification information of the target file, and then establish a corresponding relationship between the unique identity information and the download address of the target file.

It should be noted that the server may store download addresses of one or more files. It can be understood that, when the server only stores the download address of one file, the download address of one file can be used as the download address of the target file; when the server only stores the download addresses of the multiple files, the download addresses of the multiple files can all be used as the download addresses of the target file, of course, only a part of the download addresses of the multiple files are the download addresses of the target file, and in this case, the server needs to determine the download addresses of the target file at the download addresses of the multiple files according to the identification information of the target file.

As described above, the server may receive the user's identity information and the unique identity information for the download task, which may be transmitted by the second terminal. In an optional implementation manner, after determining that the user has the download authority according to the identity information of the user, the server needs to establish a corresponding relationship between the unique identity information and the download address of the target file.

Optionally, the server may record authority information of each user, and the server may query the authority information of the user according to the identity information of the user, and determine whether the user has the download authority based on the authority information. Specifically, the permission information may include a completion condition of the user for the preset task, and when the user is not completing the preset task, it is determined that the user does not have the download permission; and when the user finishes the preset task, determining that the user has the downloading authority.

In the subsequent steps, after the first terminal determines that the corresponding relationship is established, the target file can be obtained at the server according to the unique identity information. In order to ensure that the first terminal can acquire the target file in time, the server may set indication information or actively send an indication message to the first terminal, where the indication information and the indication message are used to indicate the first terminal to start acquiring the target file.
