File transmission method and device, computer equipment and storage medium

Abstract

The invention relates to a file transmission method and device, computer equipment and a storage medium. The method comprises the steps of obtaining byte data corresponding to the size of a target file; comparing the byte data with a preset threshold value; when the byte data is greater than a preset threshold value, starting double threads to transmit the target file until the residual transmission byte data of the target file is less than or equal to the preset threshold value; when the remaining transmission byte data of the target file is smaller than or equal to the preset threshold value, starting a single thread to transmit the target file; and combining the data transmitted by each thread to obtain data corresponding to the target file. By the adoption of the method, the transmission mode of the target file can be dynamically adjusted according to the size of the target file, an inverted file does not need to be created at a server side for transmission, the tedious operation process and a large amount of time are prevented from being consumed, the file transmission efficiency is effectively improved, and the downloading speed of large files is increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a file transmission method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology and the advent of the 5G era, the emergence of the Internet has brought great convenience to modern life. More and more users can use mobile terminal devices to transmit data with different Internet platforms. With the development of the Internet, FTP has become one of the most widely used protocols for file transfer on the network. The application layer protocol for transport. [0003] However, in the current FTP dual-thread download method, when users use dual-thread to download different files, they first need to create a reverse file on the server side, and copy the original file byte by byte to another file to generate a corresponding file. If the reverse file contains a large amount of byte data, it will take a lo...

Problems solved by technology

[0003] However, in the current FTP dual-thread download method, when users use dual-thread to download different files, they first need to create a reverse file on the server side, and copy the original file byte by byte to another file to generate a corresponding file. If the reverse file contains a large amount of byte data, it will take a lot of time to create the reverse file. Once the server or client has a network exception and the download is interrupted, the reverse file can only be created again. After the reverse file is generated, the two-thread Start to read the data in the original file and the reverse file respectively for transmission, which will easily lead to low file transmission efficiency
