Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

A possible system architecture applicable to the embodiments of the present application is first introduced below with reference to FIG. 1 .

Please refer to FIG. 1 , which exemplarily shows a schematic structural diagram of a system to which the embodiments of the present application are applied. The system 100 may include mobile terminals (eg, mobile terminal 1011 and mobile terminal 1012 shown in FIG. 1 ), clients (eg, client 1021 and client 1022 shown in FIG. 1 ), background server 103 , database 104 , and Third-party server 105 . Wherein, the mobile terminal 1011 (or the mobile terminal 1012) establishes a communication connection with the third-party server 105 through the network; the third-party server 105 establishes a communication connection with the background server 103 through the network; on the one hand, the background server 103 can establish a communication connection with the database 104 through the network. , on the other hand, a communication connection can also be established with the client 1021 (or the client 1022 ) through the network.

A third-party application program (APP) is installed in the mobile terminal 1011 (or the mobile terminal 1022 ), and the mobile terminal 1011 communicates with the third-party server 105 through the third-party application program. For example, the third-party application program can be WeChat, and correspondingly, the third-party server 105 can be a WeChat server. In this way, the mobile terminal 1011 can send a request message to the WeChat server through WeChat, and receive a response message returned by the WeChat server.

The client 1021 (or the client 1022) can access the webpage through a browser, and can communicate with the background server 103 corresponding to the webpage through the network. For example, the client 1021 can send a request message to the background server 103, and receive the background server 103 The returned response message; the client 1022 can send a request message to the background server 103 and receive the response message returned by the background server 103 . For example, the client 1021 accesses the webpage of 58.com through a browser. During the access process, the client 1021 can send a request message to the background server 103 of 58.com, and can also receive a response message returned by the background server 103 of 58.com.

The background server 103 may submit the received data to the database 104 .

In this embodiment of the present application, the mobile terminal 1011 (or the mobile terminal 1012 ) may be a mobile phone, a tablet computer, a smart wearable device, or the like. Client 1021 (or client 1022) may be a desktop computer or a laptop computer, or the like.

Based on the system architecture shown in FIG. 1 , FIG. 2 exemplarily shows a schematic flowchart corresponding to a file transmission method provided by an embodiment of the present application. As shown in Figure 2, it specifically includes the following steps:

Step 201, the background server generates an identification code, and sends the identification code to the client.

Step 202, the client receives the identification code generated by the background server, and displays the identification code on the webpage.

Step 203, the client sends a file echo request to the background server in a polling manner.

Step 204, the mobile terminal obtains the identification code from the web page of the client through a third-party application.

Step 205, after the mobile terminal establishes a network connection with the background server using the identification code, sends a file transfer request to the background server through a third-party application.

Step 206: After the background server establishes a network connection with the mobile terminal, it receives a file transfer request sent by the mobile terminal through a third-party application.

Step 207, the background server uploads the target file to the database, and obtains the address of the target file in the database.

Step 208, the background server receives the file echo request sent by the client, and returns a response message of the file echo request to the client.

Step 209, the client receives the response message of the file echo request returned by the background server.

Step 210, the client queries the target file from the database according to the address of the target file in the database, and echoes the target file on the web page.

Using the above method, the background server generates an identification code for the client to display the identification code on the web page. In this way, the mobile terminal can obtain the identification code from the web page and use the identification code to establish a network connection with the background server, so as to use the third-party application to establish a network connection. The program sends a file transfer request to the server; accordingly, after receiving the file transfer request, the background server can upload the target file included in the file transfer request to the database, and return the address of the target file in the database as a response message to the client , so that the client can query the target file from the database and echo the target file on the web page. It can be seen that in the embodiment of the present application, the mobile terminal can be connected to the background server only according to the identification code, and the file transmission can be realized without using a USB cable or a memory card. The entire file transmission process is simple to operate and easy to use, thereby improving the Efficiency of file transfer.

Before performing step 201, the background server may generate an identification code after receiving an identification code generation request from the client.

That is to say, when the client has a file transfer requirement, it can send an identification code generation request to the background server. Correspondingly, after receiving the identification code generation request sent by the client, the background server can generate the identification code. Wherein, the identification code generation request may include a first device identification, which is a unique identification of the client, for example, may be the media access control (Media Access Control, MAC) address of the client, or may also be the device sequence of the client No., there is no specific limitation.

Specifically, the process of generating the identification code can be triggered on the web page, that is, the client sends a request message for generating the identification code to the background server through the web page.

For example, a webpage needs to upload a file, and the file to be uploaded is stored in the user's mobile terminal. In this case, the file stored in the mobile terminal needs to be transferred to the webpage and displayed on the webpage. The user can trigger the identification code generation process on the web page (for example, click the "generate identification code" component on the web page), and the client can send an identification code generation request to the background server through the web page.

In step 201, after receiving the identification code generation request, the background server may generate an identification code by using an identification code generation tool.

The identification code may include the first device identification and connection information. The first device identifier may be the unique identifier of the client, such as the MAC address of the client, or the device serial number of the client, which is not specifically limited; the connection information may be the address of the background server, which is used to provide the mobile terminal, so that the mobile terminal uses the connection information to establish a network connection with the background server.

The connection information included in the identification code can be used for the mobile terminal to generate and send a connection request to the background server, where the connection request is used to request to use the connection information to establish a network connection between the mobile terminal and the background server.

The first device identification included in the identification code can be used to provide the mobile terminal, so that the mobile terminal generates a file transfer request according to the first device identification and the target file.

Further, the identification code may be a two-dimensional code, a barcode or encrypted information, etc., which is not specifically limited.

In step 202, the client can display the identification code on the webpage. If the identification code is a two-dimensional code, the client can display the picture of the two-dimensional code on the webpage; if the identification code is a barcode, the client can display the picture of the barcode on the webpage; if the identification code is encrypted information, the client can display the picture of the barcode on the webpage The encrypted information is displayed on the .

For the client, the identification code can be used to provide the mobile terminal, so that the mobile terminal uses the identification code to establish a network connection with the background server, and sends a file transfer request to the background server through a third-party application program.

In step 203, while (or after) displaying the identification code on the web page, the client can send a file echo request to the background server in a polling manner, that is, request the background server to return the address information of the target file in the database.

Polling, as the name suggests, means to issue a query periodically. Polling can be used to solve the problem of excessive server pressure. If multiple long connections are maintained, the server pressure will be too high. Therefore, a polling request interface can be specially established, which only retains the identification number of one task (Identity Document, ID ), the client only needs to send the ID of the task to get the status of the current task. If the result is returned, the polling is over. If no result is returned, wait for a period of time before continuing to send the request.

For example, the client can send a file echo request to the background server at time T1. If the client does not receive a response message for the file echo request, it can send the request again at time T2 (that is, a certain time after time T1). The background server sends a file echo request. If the client still does not receive a response message for the file echo request, it can send a file echo request to the background server again at time T3 (that is, a certain time after time T2) until it receives the request. The polling ends when the response message to the file echo request is reached.

In this embodiment of the present application, the file echo request may include a first device identifier, which is a unique identifier of the client, such as the client's MAC address, the client's device serial number, etc., which is not specifically limited.

The file echo request may be used to request the background server to return a response message to the file echo request corresponding to the first device identifier.

In step 204, according to different types of identification codes, the mobile terminal acquires the identification codes in different ways.

If the identification code is a QR code or a barcode, the mobile terminal can scan the QR code or barcode through a third-party application.

If the identification code is encrypted information, such as cipher text numbers, then the mobile terminal can receive the encrypted information input by the user through a third-party application program.

Before performing step 205, the mobile terminal may parse the identification code to obtain the connection information and the first device identification included in the identification code.

In step 205, after the mobile terminal parses the identification code to obtain the connection information, it can send a connection request to the background server through a third-party application. The connection request may be used to request to establish a network connection between the mobile terminal and the background server by using the connection information.

Further, the connection request may also include the user's identity information, that is, the user's identity information logged on the mobile terminal. The user's identity information may include the user's login name or the user's ID, etc., which is not specifically limited.

Before the mobile terminal sends a file transfer request to the background server through a third-party application, after the mobile terminal parses the identification code to obtain the first device identifier, the file transfer request can be generated according to the first device identifier and the target file to be transferred.

Furthermore, the mobile terminal can send a file transfer request to the background server through a third-party application. Wherein, the file transfer request may include the target file to be transferred and the first device identification; the target file is used to provide the background server, so that the background server uploads the target file to the database, and obtains the address of the target file in the database; the target file The address in the database is provided to the client, so that the client can query the target file from the database according to the address of the target file in the database, and echo the target file on the web page.

In the embodiment of the present application, the third-party application program plays a relay function, connecting the mobile terminal and the background server with the help of the third-party application program. The third-party application may be a variety of different applications, for example, the third-party application may be WeChat, or it may be Alipay, or it may also be another application with a transfer function.

It should be noted that the specific process for the mobile terminal to send a connection request to the background server through a third-party application is as follows. Forward the connection request to the background server. Similarly, in the subsequent step 206, the specific process of the mobile terminal sending the file transfer request to the background server through the third-party application is as follows, the mobile terminal sends the file transfer request to the third-party server through the third-party application, and the third-party server sends the file transfer request. Forward to the backend server.

In this embodiment of the present application, the target file may be a document file, a picture file, or a data table file, which is not specifically limited.

In step 206, after receiving the connection request sent by the mobile terminal through the third-party application, the background server can establish a network connection with the mobile terminal if it is determined that the connection information included in the connection request is correct. Furthermore, the background server may receive a file transfer request sent by the mobile terminal through a third-party application.

Specifically, after the background server receives the connection request, it parses and obtains the connection information and user identity information included in the connection request. Since the connection information is generated by the background server in the process of generating the identification code, the background server determines the connection request After the included connection information is correct, the connection information and the user identity information can be bound together. At this point, the background server establishes a network connection with the mobile terminal.

In step 207, after uploading the target file to the database, the background server can obtain the address of the target file in the database. The address of the target file in the database may be a Uniform Resource Locator (URL) address of the target file in the database.

Before performing step 208, the background server needs to determine that the second device identifier included in the file echo request matches the first device identifier included in the file transfer request. Wherein, the second device identifier is the unique identifier of the client that sends the file echo request.

For example, both client A and client B send a file echo request to the background server, where the file echo request sent by client A includes the device ID of client A, and the file echo request sent by client B includes Device ID of client B. When the background server receives the file transfer request sent by the mobile terminal, if the file transfer request includes the device ID of client A, the background server can determine that the device ID included in the file echo request sent by client A is the same as the device ID included in the file echo request sent by client A. The device identifier included in the file transfer request sent by the mobile terminal matches, and further, the background server can return a response message to the client A for the file echo request.

In step 208, the response message of the file echo request may include the address of the target file in the database. The address of the target file in the database can be provided to the client, so that the client can query the target file from the database according to the address of the target file in the database, and echo the target file on the web page.

Further, the address of the target file in the database may be the URL address of the target file in the database.

In steps 209 and 210, the client can query the target file from the database according to the address of the target file in the database, and echo the target file on the web page.

If the target file is an image file, the client can echo the image on the web page after querying the image file from the database.

If the target file is a document file, the client can echo the file (eg, echo the document name, etc.) on the web page after querying the file from the database.

In order to more clearly describe the file transfer method provided by the embodiments of the present application, the following takes the third-party application as WeChat as an example, and an overall process of file transfer is exemplified in conjunction with FIG. 3 . As shown in Figure 3, it specifically includes the following steps:

Step 301, the client sends a two-dimensional code generation request to the background server.

Step 302: After receiving the request for generating a two-dimensional code, the background server generates a two-dimensional code.

Step 303, the background server sends the two-dimensional code to the client.

Step 304, the client receives the two-dimensional code generated by the background server, and displays the two-dimensional code on the webpage.

Step 305, the client sends a file echo request to the background server in a polling manner.

Step 306, the mobile terminal opens WeChat, and obtains the two-dimensional code by scanning.

Step 307, the mobile terminal sends a connection request to the WeChat server, requesting to establish a network connection with the background server.

Step 308, the WeChat server forwards the connection request to the background server.

Step 309, after receiving the connection request, the background server establishes a network connection with the mobile terminal, and returns a response message that the connection is successful.

In step 310, the WeChat server returns a response message of successful connection to the mobile terminal, and the mobile terminal displays an indication message of successful connection on WeChat.

Step 311, the mobile terminal sends a file transfer request to the WeChat server through WeChat.

Step 312, the WeChat server forwards the file transfer request to the background server.

Step 313, after receiving the file transfer request, the background server uploads the target file to the database, and obtains the address of the target file in the database.

Step 314, if the background server determines that the device identifier included in the file echo request sent by the client matches the device identifier included in the file transfer request sent by the mobile terminal, then the backend server receives the file echo request sent by the client, and sends the request to the client. The client returns a response message for the file echo request.

Step 315, the client receives the response message of the file echo request returned by the background server.

Step 316, the client queries the target file from the database according to the address of the target file in the database, and echoes the target file on the web page.

It should be noted that the above steps 301 to 316 are only an example, and in other possible examples, the mobile terminal can also communicate with the background server through other existing applications, or can also use a new independently developed application. The application program communicates with the background server, which is not limited.

Considering that with the increase of access volume, one background server 105 shown in FIG. 1 may not be able to meet the increasing access demand, in this embodiment of the present application, a background server cluster can be set to relieve the pressure on the background server 105 .

The background server cluster 403 may include multiple background servers. For example, the background server cluster 403 shown in FIG. 4 may include a background server 4031 , a background server 4032 and a background server 4033 . A communication connection can be established between any two background servers through the network. For example, a communication connection can be established between the background server 4031 and the background server 4032 through the network, and a communication connection can be established between the background server 4032 and the background server 4033 through the network. A communication connection can be established between 4031 and the background server 4033 through the network.

The client device 4021 (or the client 4022) can send a request message to any one of the background servers in the background server cluster 403, and receive a response message returned by any one of the background servers. For example, the client 4021 accesses the webpage of 58.com through a browser. During the access process, the client 4021 can send a request message to the background server 4031 of 58.com, and can also receive a response message returned by the background server 4032 of 58.com.

The background server 4031 (or the background server 4032 , or the background server 4033 ) can submit the received data to the database 404 .

In this embodiment of the present application, the mobile terminal 4011 (or the mobile terminal 4012 ) may be a mobile phone, a tablet computer, a smart wearable device, or the like. The client 4021 (or the client 4022) may be a desktop computer or a laptop computer, or the like.

Step 502, after receiving the identification code generation request, the first background server generates an identification code, and sends the identification code to the client.

Step 503, the client receives the identification code and displays the identification code on the webpage.

Step 504, the client sends a file echo request to the first background server in a polling manner.

Step 505, the mobile terminal obtains the identification code from the web page of the client through a third-party application.

Step 506, the mobile terminal parses the identification code to obtain the connection information and the first device identification included in the identification code.

Step 507, the mobile terminal sends a connection request to the second background server through a third-party application.

Step 508: After receiving the connection request sent by the mobile terminal, the second background server establishes a network connection with the mobile terminal.

Step 509, after establishing a network connection with the background server, the mobile terminal sends a file transfer request to the second background server through a third-party application.

Step 510, after receiving the file transfer request, the second background server uploads the target file to the database, and obtains the storage address of the target file in the database.

Step 511, the second background server determines the target client corresponding to the second device identification that matches the first device identification, and determines the first background server that receives the file echo request sent by the target client, and stores the target file in the database. The address in is sent to the first background server.

Step 512, the first background server returns a response message of the file echo request to the target client.

Step 513: The client receives the response information of the file echo request returned by the first background server, queries the target file from the database according to the address of the target file in the database, and echoes the target file on the web page.

It should be noted that, in the above steps 501 to 513, the first backend server and the second backend server may be the same backend server, or may be different backend servers. When the first backend server and the second backend server are different backend servers, the first backend server may be any backend server in the backend server cluster, and the second backend server may be a backend server other than the first backend server in the backend server cluster any of the backend servers.

By adopting the above method, on the one hand, the mobile terminal can be connected with the background server only according to the identification code, and then the file transfer can be realized without using a USB cable or a memory card. The entire file transfer process is simple and easy to use, thereby improving the The efficiency of file transfer; on the other hand, using a background server cluster to serve the client's web page can effectively improve the processing efficiency of the background server.
