Download management method, download management unit and download system

Abstract

The invention discloses a download management method, a download management unit and a download system, wherein the download management method includes the following steps: the download management unit receives a file download request assigned by a file application program, the file download request carries a Uniform Resource Locator corresponding to a file requested to download by the file application program and the Uniform Resource Locator includes a Protocol ID; according to the Protocol ID included in the Uniform Resource Locator, a protocol processing unit corresponding to the Protocol ID is called to download the file; and after the file downloaded by the protocol processing unit is received, the file is forwarded to the file application program. The technical proposal provided by the embodiment is conducive to simplifying the structure of the file application program, improves the system expandability, and relatively lowers the complexity of code maintenance.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a download management method, a download management unit and a download system. Background technique [0002] In a TV system, a device can access resources stored on multiple storage media, and accessing storage media using different protocols requires calling different protocol access functions. For example, accessing a server using the Hypertext Transfer Protocol (HTTP, Hypertext Transfer Protocol) requires calling an HTTP protocol access function, accessing a server using the File Transfer Protocol (FTP, File Transfer Protocol) requires calling an FTP protocol access function, and so on. [0003] In the existing file access mode, a file application program (for example, a browser, etc.) in the device is provided with multiple function call interfaces, and each function call interface corresponds to calling a protocol access function. If a file application program needs to us...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that in the existing file access mode, file application programs such as browsers need to set multiple function call interfaces, resulting in a relatively complicated program structure; if new protocols need to be supported, then The source code of the file application needs to be modified, which may affect its operational reliability and also increase the complexity of code maintenance
