In order to enable those skilled in the art to more clearly understand the technical solution provided by the embodiment of the present invention, a data transmission method provided by the embodiment of the present invention is described in detail below by using a third specific embodiment. The embodiment of the invention is applied to a network system, as shown in fig. 3, the network system comprises a target server, a proxy server and a client, the client can be a mobile phone or a tablet computer, wherein the target server and the proxy server form a network side, and before file transmission between the network side and the client is interrupted, the client transmits a target file with the target server by transmitting a target file request, as shown in fig. 4, the method comprises the following steps:
401. and the client side transmits a target file transmission request to the target server, and starts to transmit the target file with the target server.
The transfer target file request may include URL (Uniform resource locator) information of the target file. The target server may obtain a target file according to the URL information, and send the target file to the client after obtaining the target file, where the URL information may include a server identifier, and the server identifier is used to record whether the target server supports a breakpoint resume function.
402. After sending the transmission target file request, the client sends an automatic download setting request instruction to the proxy server, so that the proxy server generates the automatic download setting instruction according to the automatic download setting request instruction.
For example, the automatic download setting request instruction may include URL information and a client identification.
Wherein the client identity is assigned by the proxy server. The client identifier may be randomly generated by the proxy server and used for uniquely identifying the client, or may be generated by the proxy server according to the registration information of the client on the proxy server. The registration information may be a registered account and a registered password, or may be other parameters such as a device name, which is not limited herein.
The way in which the proxy server generates the client identity from the registration information of the client on the proxy server may include the following steps 402a-402b, as shown in fig. 5:
402a, the proxy server acquires the registration information of the client.
For example, the registration information may be a registration account and a registration password, such as an instant messaging account and password, a mailbox account and mailbox password, and the like.
Specifically, a client actively sends a login request to a proxy server, the login request carries registration information, the proxy server verifies the registration information in the login request after receiving the login request of the client, and acquires the registration information after the verification is successful; if the proxy server is successfully verified, the client may log in to the proxy server and perform 402b accordingly. If the proxy server fails in verification, the client cannot log in the proxy server and sends prompt information to the client to inform the client of the failure in logging in.
The proxy server may also verify the client by using other verification algorithms and then acquire the registration information, and a specific acquisition manner is not limited herein.
402b, the proxy server generates a client identification according to the registration information of the client.
Specifically, the proxy server generates a client Identifier according to the registration information of the client, where the client Identifier may also be a GUID (global Unique Identifier).
403. And the proxy server sends an automatic download setting instruction to the client so that the client can generate an automatic download setting interface according to the automatic download setting instruction.
It should be noted that the proxy server may also actively send the automatic download setting instruction to the client when the target server receives a target file transmission request from the client, may also send the automatic download setting request instruction to the proxy server when the client starts to transmit the target file with the target server, and may also send the automatic download setting request instruction to the proxy server by the client during the transmission of the target file with the target server, which is not limited here.
404. And the client displays an automatic download setting interface according to the automatic download setting instruction sent by the proxy server.
Illustratively, as shown in fig. 6, the automatic download setting interface may include: the automatic download setting method comprises the steps that automatic download setting request information can be set to be whether automatic download is set or not, the automatic download interface further comprises a user selection icon, the user selection icon can be an icon corresponding to the character 'yes' and an icon corresponding to the character 'no', if the user selects the icon corresponding to the character 'yes' in the automatic download setting interface, the client judges that the user selects automatic download, and an automatic download setting response instruction is correspondingly generated; and if the user selects the icon corresponding to the character 'no' in the automatic download setting interface, the client judges that the user does not select automatic download.
Optionally, the automatic download setting interface may further include: the icon for the user to perform other setting operations such as saving the catalog setting and the network use environment setting can be an icon corresponding to the character "other setting", and the user obtains other setting interfaces such as a saving catalog setting interface and an automatically downloaded network environment setting interface by selecting the icon corresponding to the character "other setting".
405. The client generates an automatic downloading request according to an automatic downloading setting response instruction triggered on an automatic downloading setting interface by a user, and sends the automatic downloading request to the proxy server.
Notably, the automatic download request can include URL information and a client identification of the target file.
The steps 401 to 405 are automatic download setting processes, and the automatic download setting processes may be in other forms besides the modes listed in the embodiments of the present invention, for example, setting is performed in a system setting menu of the client, and file transmission of all clients is set as automatic download.
406. And when the transmission of the target file is interrupted, the client acquires the transmission progress information of the target file.
The transmission progress information is used for determining the initial position of a part of files which are not transmitted by the client in the target file when the file transmission is interrupted and the URL information of the target file, and according to the transmission progress information, the client can continuously transmit the target file from the initial position in the subsequent process.
Specifically, when the transmission of the target file is determined to be interrupted, the client saves the URL information of the target file and the starting position of the part of the file which is not transmitted by the client when the file transmission is interrupted in the target file. And generating transmission progress information according to the URL information of the target file and the initial position of the part of the file which is not transmitted by the client in the target file.
407. And when the transmission of the target file is interrupted, the proxy server acquires transmission interruption information.
Specifically, when it is determined that the transmission of the target file is interrupted, the proxy server generates transmission interruption information by using the URL information in the monitoring information and the start position of the part of the file in the target file that is not transmitted by the client when the transmission of the target file is interrupted, so that the proxy server can determine the target server where the target file is located by using the transmission interruption information in the subsequent process, and download at least the part of the file in the target file that is not transmitted by the client from the target server.
The monitoring information is generated by monitoring the transmission between the client and the target server by the proxy server after the proxy server receives the automatic downloading request sent by the client.
The proxy server monitors the transmission of the target file between the client and the target server, so that the proxy server can acquire the URL information, the position of the part of the file in the target file transmitted by the client during file transmission and the network environment by using the monitoring information in the monitoring process, and when the proxy server knows the transmission interruption of the target file according to the monitoring information, the proxy server can acquire the initial position of the part of the file in the target file not transmitted by the client during the transmission interruption of the target file and the URL information of the target file by using the monitoring information.
Meanwhile, when the transmission of the target file is interrupted, 406 is a step of acquiring transmission progress information for the client, 407 is a step of acquiring transmission interruption information for the proxy server, and 406 and 407 may be executed according to the sequence listed in this embodiment, may be executed simultaneously, or may be executed according to other sequences, which is not limited herein.
Optionally, after the transmission of the target file is interrupted, the proxy server may further determine whether the target server supports the breakpoint resuming function according to the server identifier included in the URL information.
If the target server does not support the breakpoint resume function, execution is performed 408.
If the target server supports the breakpoint resume function, after the network environment reaches a preset condition, sending a prompt message to the client to inform the client that the target server supports the breakpoint resume function, so that the client sends a transmission request to the target server after the network environment reaches the preset condition.
Optionally, the client may also determine whether the target server supports the breakpoint resuming function according to the server identifier.
At this time, if the target server does not support the breakpoint resume function, 408 is executed.
If the target server supports the breakpoint continuous transmission function, the client actively sends a transmission request to the target server after detecting that the network environment reaches a preset condition. When the transmission of the client is interrupted, the transmission progress information is recorded and the network environment is continuously detected, so that once the network environment is detected to reach the preset condition, the user does not need to continuously download the interrupted transmission at the client and the like, but the background of the client actively sends a transmission request to obtain a part of files which are not transmitted by the target file.
408. And the proxy server downloads at least part of the files which are not transmitted by the client in the target files from the target server according to the transmission interruption information.
Illustratively, the proxy server obtains a target server where the target file is located according to the transmission interruption information, then establishes a file transmission path with the target server, and finally downloads a part of the file which is not transmitted by the client in the target file from the target server according to the transmission interruption information. Alternatively, the first and second electrodes may be,
after a file transmission path is established with the target server, the target file is downloaded from the target server, and the file loss is avoided by downloading the target file completely and acquiring the part of the file which is not transmitted from the target file in the subsequent process.
In the embodiment of the present invention, the proxy server has the breakpoint resume function, that is, even if the target server does not provide the breakpoint resume service, the proxy server may replace the client to download the file in a manner of downloading the target file entirely or only partially in the case of network interruption of the client, so as to provide the breakpoint resume service for the client in the subsequent process.
409. And when the network environment reaches a preset condition, the client sends a transmission request to the proxy server, wherein the transmission request comprises transmission progress information.
Optionally, the client determines whether the network environment meets a preset condition.
Wherein, because cause the reason that the transmission of target file was interrupted can include that the network signal is poor, the customer end leaves WIFI network etc. so, the mode that the customer end judges whether network environment reaches preset condition can include judging whether the customer end can receive the network signal and whether the customer end is reconnected with the WIFI network etc. to judge whether the customer end can receive the network signal as an example, this judgement process can specifically be:
and the client judges whether the client can receive the network signal according to whether the received signal strength of the network side reaches a preset threshold value. If the received signal strength of the network side reaches a preset threshold value, judging that the client can receive the network signal; and if the received signal strength of the network side does not reach the preset threshold value, judging that the client cannot receive the network signal.
Specifically, it may also be determined whether the transmission speed of the transmission channel between the client and the network side reaches a preset threshold, and whether the client can receive the network signal, or whether the client can receive the network signal according to other parameters, and a specific execution mode is not limited here.
And after judging that the network environment reaches the preset condition, the client sends a transmission request to the proxy server, wherein the transmission request comprises URL information, a client identifier and transmission progress information.
410. And the proxy server receives the transmission request sent by the client and sends part of the file to the client according to the transmission progress information in the transmission request.
Optionally, the proxy server performs authentication operation on the client according to the client identifier in the transmission request, after the authentication is successful, the proxy server searches for a part of the file of the target file according to the transmission request, and after obtaining the part of the file, sends the part of the file to the client. Alternatively, the first and second electrodes may be,
the proxy server searches the target file according to the transmission request, acquires a part of file according to the initial position of the part of file which is not transmitted by the file end in the target file, and then sends the part of file to the client.
411. The client receives the partial file and generates a target file according to the file saved by the client and the partial file.
Specifically, the file saved by the client and the partial file form a complete file according to the initial position of the partial file which is not transmitted in the transmission progress information in the target file.
Optionally, after the client generates the target file, the client may display a file download completion prompt interface to prompt the user that the target file has been downloaded.
