Embodiment Construction

[0027] The application will be described in further detail below in conjunction with the accompanying drawings.

[0028] In a typical configuration of the present application, the terminal and the equipment serving the network include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0029] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0030] Computer-readable media includes both volatile and non-volatile, removable and non-removable media, and can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dy...

Abstract

The invention aims at providing a method and device for acquiring a transmitted file. The method particularly comprises the steps that multiple fragment information of a transmitted target file is acquired; a fragment sequence of the fragment information is generated; an union set of all content fragments is acquired; and when the content size of the union set is equal to the target file size, content corresponding to the union set is taken as a transmission result of the target file. Compared with the prior art, the method has the advantages that the multiple fragment information of the transmitted target file is acquired, the fragment sequence of the fragment information is generated according to the order relation of the content fragments, included by the fragment information, of the target file, then the union set of all the content fragments in the fragment sequence is acquired, and when the content size of the union set is equal to the target file size, the content correspondingto the union set is taken as the transmission result of the target file; and accordingly, the complete content of the transmitted target file is obtained on the condition that the target file is transmitted unsuccessfully multiple times to complete transmission.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a technology for acquiring transmission files. Background technique [0002] With the advent of the big data era, storage and transmission technologies have developed accordingly, and more and more users use online storage or transmission to process files. However, due to network, system, hardware and other factors, the file may be interrupted during the transfer and the complete file transfer cannot be completed. In the prior art, a simple transmission retry is often adopted, so that the file transmission can be completed when the network and system environment are good for a certain time. However, under the influence of factors such as poor network conditions, there will be multiple retry transmission interruptions, resulting in problems such as occupying the storage space of the network server, occupying network bandwidth, and taking a long time. Contents of the inven...
