Abstract

The invention relates to a webpage search engine technology, and aims at providing a web crawler system based on a browser kernel. The web crawler system based on the browser kernel comprises a browser engine module, a network communication module and a strategy module and is used for conducting page analyzing and finding URLs of other pages. According to the web crawler system based on the browser kernel, resources relied by a page are dynamically loaded through the built-in browser kernel by using a dynamic analysis technology, Javascript is executed, dynamic operations such as events of simulating mouse clicks, double clicks and carriage return are conducted on a DOM node to find a new page, and the defects of a traditional crawler are overcome.

Description

technical field [0001] The invention relates to the technical field of webpage search engines, in particular to a browser kernel-based web crawler system. Background technique [0002] Web crawlers have a wide range of application scenarios. They are an important part of web search engines and are also used to obtain specific information on the Internet. The core function of a web crawler is to discover the URLs of other pages from a page. [0003] At present, common web crawlers are all based on static analysis of pages - when analyzing pages, they will not dynamically execute Javascript scripts in the pages, nor will they load resources such as pictures and scripts in the pages. When statically analyzing a page, it mainly extracts the Label, <form> Tags, etc. may contain content pointing to other page URLs. [0004] With the rapid development of Internet technology, the implementation methods of web pages are becoming more and more diverse, and various front-en...
