Embodiment 1

[0071] The embodiment of the present invention provides a file download method, please refer to figure 1 , which is a schematic flowchart of Embodiment 1 of the file downloading method provided by the embodiment of the present invention. This embodiment is a method for realizing file downloading at the client side. As shown, the method includes the following steps:

[0072] S101. Send an identifier of the compressed file to a server, so that the server obtains information of candidate files included in the compressed file according to the identifier of the compressed file.

[0073] Specifically, the client determines the compressed file where the required target file is located, and then sends the identifier of the compressed file to the server, so that the server obtains the candidate files contained in the compressed file according to the identifier of the compressed file Information.

[0074] The server may send a full file list to the client, and the full file list inclu...

Embodiment 2

[0086] The embodiment of the present invention provides a file download method, please refer to figure 2 , which is a schematic flowchart of Embodiment 2 of the file downloading method provided by the embodiment of the present invention. This embodiment is a method for realizing file downloading on the server side. As shown, the method includes the following steps:

[0087] S201. Receive the identifier of the compressed file sent by the client.

[0088] Specifically, the server may receive the identifier of the compressed file sent by the client.

[0089] Preferably, the server may send a full file list to the client in advance, and the full file list includes information of at least one compressed file. Then, the client can present the full file list to the user, so that the user can select the compressed file where the desired target file is located in the full file list, and the client determines the compressed file according to the user's selection, and then sends the c...

Abstract

An embodiment of the invention provides a file download method, device and system. According to the invention, a mark of a compressed file is sent to a server, so that the server can acquire information of a candidate file contained in the compressed file according to the mark of the compressed file. Therefore, the information of the candidate file can be received by the server and then a target file in the candidate file can be downloaded according to the information of the candidate file. By adopting the technical scheme provided by the invention, an aim of downloading the determined target file only can be realized and file downloading efficiency and file downloading flexibility are improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of Internet applications, in particular to a file downloading method, device and system. [0003] 【Background technique】 [0004] At present, the client installed in the terminal can first download the file from the server through the network, and then can view the file at any time in the client. [0005] In the prior art, when the client needs to view a certain file in the compressed file, it needs to download the compressed file from the server first, and then the client uses a decompression tool to decompress the compressed file, so as to view all the files contained in the compressed file. The client cannot select the specified file in the compressed file to download the required target file. For example, the size of the compressed file is 1G, even if the client only needs 1kb of the file, the entire 1G file must be downloaded. Therefore, when the client downloads the specified target file, the...
