Embodiment Construction

[0023] A method for downloading Internet audio and video programs provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation examples.

[0024] At present, there are two major problems in the process of downloading audio and video programs on the Internet, mainly in the aspect of address resolution. javascript scripts, the script content is also different, javascript scripts encrypt audio and video information (such as network addresses), and audio and video websites also obfuscate javascript scripts, it is difficult to obtain audio and video network addresses by parsing javascript scripts. The other is the problem of not being able to obtain the internal information of the player in the webpage. Because browsers usually support plug-ins, most video sites use videos in FLV format. The server client uses a FLASH player to play, these video URLs cannot be obtained from the page content, and the in...

Abstract

A method for downloading videos and audios of the internet belongs to the field of the internet and overcomes the problem that the videos and the audios cannot be downloaded due to the fact that complicated scripts and network addresses of videos in FLV (flash video) formats cannot be processed in analysis of the network audio and video programs during downloading of the videos and the audios of the internet. Access characteristics of browsing video and audio pages by users and HTTP (hypertext transport protocol) network characteristics of addresses of the audios and the video programs are utilized sufficiently, universal judgment on the analysis of the addresses of the network audios and videos is realized by analyzing the intercepted HTTP header information, and finally the audio and the video programs are downloaded successfully. The method for downloading videos and audios of the internet solves the problem about high-efficiency address analysis and downloading of the audio and video files for the supervision department.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically, the present invention relates to a method for downloading audio and video from the Internet. Background technique [0002] Regulatory departments need to effectively discover and download online audio and video programs for monitoring and management. Downloading of Internet audio and video programs develops along with the growth of network audio and video programs in recent years, especially the growth of videos in FLV format. The key to Internet audio and video downloading lies in the discovery of network audio and video program addresses. The difficulties faced by this problem are mainly that complex scripts containing audio and video programs are difficult to handle, and the address of FLV videos is difficult to obtain from page analysis. In the process of watching videos, users cannot download them, and they have to face continuous buffering when ...
