Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

A possible system architecture to which the embodiments of the present application are applicable will be first described with reference to fig. 1.

Referring to fig. 1, a schematic structural diagram of a system to which an embodiment of the present application is applicable is exemplarily shown. The system 100 may include mobile terminals (e.g., mobile terminal 1011 and mobile terminal 1012 shown in fig. 1), clients (e.g., client 1021 and client 1022 shown in fig. 1), backend 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 a network; the third-party server 105 and the background server 103 establish a through connection through a network; background server 103 may establish a communication connection with database 104 via a network, on the one hand, and may also establish a communication connection with client 1021 (or client 1022) via a network, on the other hand.

A third party Application (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. For example, the third-party application may be a WeChat, and accordingly, the third-party server 105 may be a WeChat server, such that the mobile terminal 1011 may send a request message to the WeChat server via the WeChat and receive a response message returned by the WeChat server.

The client 1021 (or the client 1022) can access the web page through the browser, and can communicate with the background server 103 corresponding to the web page through the network, for example, the client 1021 can send a request message to the background server 103 and receive a response message returned by the background server 103; client 1022 may send a request message to backend server 103 and receive a response message returned by backend server 103. For example, the client 1021 accesses 58 a web page in the same city through a browser, and during the access, the client 1021 may send a request message to 58 the backend server 103 in the same city, or may receive a response message returned by 58 the backend server 103 in the same city.

Backend server 103 may submit the received data to database 104.

In this embodiment, the mobile terminal 1011 (or the mobile terminal 1012) may be a mobile phone, a tablet computer, an intelligent wearable device, or the like. The client 1021 (or the client 1022) may be a desktop computer or a notebook computer, etc.

Based on the system architecture shown in fig. 1, fig. 2 exemplarily shows a flowchart corresponding to a file transmission method provided in the embodiment of the present application. As shown in fig. 2, the method 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 display back request to the background server in a polling mode.

And step 204, the mobile terminal acquires the identification code from the webpage of the client through the third-party application program.

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

And step 206, after the background server establishes network connection with the mobile terminal, receiving a file transmission request sent by the mobile terminal through a third-party application program.

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

And step 208, the background server receives the file playback request sent by the client and returns a response message of the file playback request to the client.

And step 209, the client receives a response message of the file echoing 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 displays the target file on the webpage.

Before performing step 201, the backend server may generate the identification code after receiving the identification code generation request of the client.

That is, when the client has a file transfer request, an identification code generation request may be sent to the background server. Accordingly, after receiving the identification code generation request sent by the client, the background server can generate the identification code. The identifier generation request may include a first device identifier, where the first device identifier is a unique identifier of the client, and may be, for example, a Media Access Control (MAC) address of the client, or may also be a device serial number of the client, which is not limited specifically.

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

For example, a certain web page has a file uploading requirement, and a file to be uploaded is stored in a mobile terminal of a user, and at this time, the file stored in the mobile terminal needs to be transmitted to the web page and displayed on the web page. The user may trigger the process of generating the identification code on the web page (e.g., click on a "generate identification code" component on the web page), and the client may 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 the identification code by using an identification code generation tool.

The identification code may include a first device identification and connection information. The first device identifier may be a unique identifier of the client, for example, a MAC address of the client, or may also be a device serial number of the client, which is not limited specifically; the connection information may be an address of the background server, which is provided to the mobile terminal, so that the mobile terminal can establish a network connection with the background server using the connection information.

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

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

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

In step 202, the client may present the identification code on the web page. If the identification code is a two-dimensional code, the client can display a picture of the two-dimensional code on a webpage; if the identification code is a bar code, the client can display a picture of the bar code on the webpage; if the identification code is encrypted information, the client may present the encrypted information on the web page.

For the client, the identification code may be used to provide to the mobile terminal, so that the mobile terminal establishes a network connection with the backend server using the identification code, and sends a file transfer request to the backend server through the third-party application.

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

Polling, as the name implies, means issuing queries at regular times. The polling can be used for solving the problem of overlarge server pressure, if a plurality of long connections are kept, the server pressure is overlarge, so that a polling request interface can be specially established, only an Identity Document (ID) of a task is reserved in the polling request interface, and the client can acquire the condition of the current task only by sending the ID of the task. If the result is returned, the polling is finished, and if the result is not returned, the request is continuously sent after waiting for a period of time.

For example, the client may send the file playback request to the background server at time T1, may send the file playback request to the background server again at time T2 (i.e., at a time after time T1) if the client does not receive the response message of the file playback request, and may send the file playback request to the background server again at time T3 (i.e., at a time after time T2) until the polling is finished after receiving the response message of the file playback request.

In this embodiment of the application, the file playback request may include a first device identifier, where the device identifier is a unique identifier of the client, and may be, for example, a MAC address of the client, a device serial number of the client, and the like, which is not limited specifically.

The file echo request can be used for requesting the background server to return a response message of the file echo request corresponding to the first device identification.

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

If the identification code is a two-dimensional code or a bar code, the mobile terminal can scan the two-dimensional code or the bar code through a third-party application program.

If the identification code is encrypted information, such as a ciphertext digit, the mobile terminal may receive the encrypted information input by the user via the third party application.

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

In step 205, after the mobile terminal analyzes the identification code to obtain the connection information, a connection request may be sent to the backend server through the third-party application program. The connection request may be used to request that the network connection between the mobile terminal and the background server is established using the connection information.

Further, the connection request may also include identity information of the user, i.e. the identity information that the user is logged in on the mobile terminal. The identity information of the user may include a login name of the user or an ID of the user, and is not limited specifically.

Before the mobile terminal sends a file transmission request to the background server through the third-party application program, the mobile terminal analyzes the identification code to obtain a first equipment identifier, and then the file transmission request can be generated according to the first equipment identifier and the target file to be transmitted.

Furthermore, the mobile terminal can send a file transmission request to the background server through the third-party application program. The file transmission request can comprise a target file to be transmitted and a first device identifier; the target file is used for being provided for 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 address of the target file in the database is used for providing the client, so that the client can inquire the target file from the database according to the address of the target file in the database and can display the target file back on the webpage.

In the embodiment of the application, the third-party application program has a transfer function, and the mobile terminal and the background server are connected through the third-party application program. The third party application may be a variety of different applications, for example, the third party application may be a WeChat application, or may also be a Payment application, or may also be another application with a transfer function.

It should be noted that, a specific process of the mobile terminal sending the connection request to the backend server through the third-party application program is as follows, the mobile terminal sends the connection request to the third-party server (that is, the server of the third-party application program) through the third-party application program, and the third-party server forwards the connection request to the backend 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 program is as follows, where the mobile terminal sends the file transfer request to the third-party server through the third-party application program, and the third-party server forwards the file transfer request to the background server.

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

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

Specifically, after receiving the connection request, the background server analyzes the connection information and the user identity information included in the connection request, and the connection information is generated by the background server in the process of generating the identification code, so that the background server can bind the connection information and the user identity information together after determining that the connection information included in the connection request is correct, and the background server and the mobile terminal establish network connection.

In step 207, after the background server uploads the target file to the database, the address of the target file in the database may be obtained. 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 identification included in the file echo request matches the first device identification included in the file transfer request. And the second equipment identification is the unique identification of the client side which sends the file display back request.

For example, both the client a and the client B send file playback requests to the background server, where the file playback request sent by the client a includes the device identifier of the client a, and the file playback request sent by the client B includes the device identifier of the client B. When the background server receives a file transmission request sent by the mobile terminal, if the file transmission request includes the device identifier of the client a, the background server may determine that the device identifier included in the file playback request sent by the client a matches the device identifier included in the file transmission request sent by the mobile terminal, and further, the background server may return a response message of the file playback request to the client a.

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 used for providing the client, so that the client can inquire the target file from the database according to the address of the target file in the database and can display the target file back on the webpage.

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 may query the database for the target file according to the address of the target file in the database, and display the target file back on the web page.

If the target file is a picture file, the client can display the picture back on the webpage after inquiring the picture file from the database.

If the target file is a document file, the client may display the file (e.g., display the document name) on the web page after querying the file from the database.

In order to more clearly describe the file transmission method provided in the embodiment of the present application, taking the third-party application as an example, and referring to fig. 3, an overall process of file transmission is exemplarily described below. As shown in fig. 3, the method 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 two-dimension code generation request, the background server generates a two-dimension code.

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

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

Step 305, the client sends a file display back request to the background server in a polling mode.

And step 306, the mobile terminal opens the WeChat and acquires the two-dimensional code in a scanning mode.

And 307, the mobile terminal sends a connection request to the WeChat server to request to establish 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 of successful connection.

And 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 the WeChat.

Step 311, the mobile terminal sends a file transmission request to the wechat server through the wechat.

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

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

In step 314, if it is determined that the device identifier included in the file playback request sent by the client matches the device identifier included in the file transmission request sent by the mobile terminal, the background server receives the file playback request sent by the client, and returns a response message of the file playback request to the client.

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

In step 316, the client queries the target file from the database according to the address of the target file in the database, and displays the target file back 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 may also communicate with the backend server through other existing applications, or may also communicate with the backend server through a new application developed independently, which is not limited specifically.

Considering that one backend server 105 shown in fig. 1 may not be able to meet the increasing access demand as the access amount increases, in the embodiment of the present application, the pressure of the backend server 105 may be relieved by setting up a backend server cluster.

Fig. 4 is a schematic diagram illustrating another system architecture provided in the embodiment of the present application. The system 400 may include mobile terminals (e.g., mobile terminal 4011 and mobile terminal 4012 shown in fig. 4), clients (e.g., client 4021 and client 4022 shown in fig. 4), a cluster of backend servers 403, a database 404, and a third party server 405. Wherein, the mobile terminal 4011 (or the mobile terminal 4012) establishes communication connection with the third-party server 405 through a network; the third-party server 405 and the background server cluster 403 establish a through connection through a network; background server cluster 403 may establish a communication connection with database 404 through a network on the one hand, and may also establish a communication connection with client 4021 (or client 4022) through a network on the other hand.

Third-party application programs (APP) are installed in the mobile terminal 4011 (or the mobile terminal 4022), and the mobile terminal 3011 communicates with the third-party server 405 through the third-party application programs. For example, the third-party application may be a WeChat, and accordingly, the third-party server 405 may be a WeChat server, so that the mobile terminal 4011 may send a request message to the WeChat server through the WeChat and receive a response message returned by the WeChat server.

The client 4021 (or the client 4022) may access a web page through a browser, and may communicate with the background server cluster 403 corresponding to the web page through a network.

Background server cluster 403 may include multiple background servers, for example, background server cluster 403 shown in fig. 4 may include background server 4031, background server 4032, and background server 4033. Any two background servers can establish communication connection through a network, for example, the background server 4031 and the background server 4032 can establish communication connection through a network, the background server 4032 and the background server 4033 can establish communication connection through a network, and the background server 4031 and the background server 4033 can establish communication connection through a network.

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

Backend server 4031 (or backend server 4032 or 4033) may submit the received data to database 404.

In this embodiment, the mobile terminal 4011 (or the mobile terminal 4012) may be a mobile phone, a tablet computer, an intelligent wearable device, or the like. The client 4021 (or the client 4022) may be a desktop computer, a notebook computer, or the like.

Based on the system architecture shown in fig. 4, fig. 5 exemplarily shows a flowchart corresponding to a file transmission method provided in the embodiment of the present application. As shown in fig. 5, the method specifically includes the following steps:

step 501, a client sends an identification code generation request to a first background server.

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 playback request to the first background server in a polling manner.

Step 505, the mobile terminal obtains the identification code from the webpage of the client through the third-party application program.

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

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

And step 508, after receiving the connection request sent by the mobile terminal, the second background server establishes network connection with the mobile terminal.

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

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

And 511, the second background server determines a target client corresponding to the second equipment identifier matched with the first equipment identifier, determines the first background server receiving a file playback request sent by the target client, and sends the address of the target file in the database to the first background server.

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

Step 513, the client receives the response information of the file playback 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 plays back the target file on the webpage.

In steps 501 to 513, the first backend server and the second backend server may be the same backend server or different backend servers. When the first background server and the second background server are different background servers, the first background server may be any one background server in the background server cluster, and the second background server may be any one background server in the background server cluster except the first background server.

By adopting the method, on one hand, the mobile terminal and the background server can be connected only according to the identification code, so that the file transmission can be realized without using a USB (universal serial bus) wire or a memory card, the whole file transmission process is simple to operate and convenient to use, and the file transmission efficiency can be improved; on the other hand, the background server cluster is adopted to serve the web page of the client, so that the processing efficiency of the background server can be effectively improved.
