Abstract

The multi-task processing system based on the crawler technology comprises: a crawler engine, wherein the crawler engine is used for controlling the processing flow of the system; the scheduler whichis used for receiving a command of the crawler engine and feeding back an execution result to the crawler engine; the downloader which is used for receiving a command of the scheduler and capturing page data; the pipeline assembly which is used for receiving the page data captured by the downloader and processing the page data. The scheduler is in communication connection with the crawler engine,the downloader and the pipeline, and the downloader is in communication connection with the pipeline assembly. Compared with a traditional crawler technology, the crawler speed is increased through the mechanism, downloading failure caused by the fact that access is never forbidden by the crawler technology discovered by a website can be prevented, and the crawler effect is improved by 300%.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and specifically relates to a multi-task processing system and method based on crawler technology. Background technique [0002] With the development of the Internet, the way people obtain information is gradually replaced by the Internet. In the early days of Internet development, people mainly obtained the information they needed by browsing portal websites, but with the rapid development of the Web, it became more and more difficult to find the information they needed in this way. At present, most people obtain useful information through search engines. Therefore, the development of search engine technology will directly affect the speed and quality of people's access to the information they need. [0003] In 1994, the world's first web search tool, Web Crawler, came out. At present, the more popular search engines include Baidu, Google, Yahoo, Info seek, Inktomi, Teoma, Live Search...
