Abstract

The embodiment of the invention provides a file transmission method based on an abstract value, a terminal, and a file server. The method comprises the steps that a source terminal calculates the abstract value of a file after receiving a file transmission instruction, and enables the abstract value disposed in a file uploading request to be transmitted to the file server; the file server searches a file serial number corresponding to the abstract value in the file uploading request, and then enables the file serial number in a first message to be returned; the source terminal enables the file serial number in the first message to be carried in a file downloading instruction and to be transmitted to a target terminal according to the identification of the target terminal in a transmission instruction; and the target terminal downloads a corresponding file from the file server according to the received file serial number. The method can saves the network bandwidth and server resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, the present invention relates to a method for transferring files based on abstract values, a terminal and a file server. Background technique [0002] With the advancement of science and technology and the development of society, networks such as the Internet and mobile Internet have been widely popularized. Users usually access the network through terminals such as desktop computers, smart phones, and tablet computers to obtain information, online shopping, and information interaction. [0003] In the process of information exchange, files usually need to be transferred between terminals. For example, files are transferred between terminals during instant messaging. [0004] At present, a file transmission method includes: a source terminal uploads a file to a server; the server receives and stores files sent by multiple source terminals for downloading by multipl...
