The basic principle of reptiles Crawlers are automated procedures for acquiring and retrieving Web pages and storing information . Get Web page:Access to the Web page is to obtain the source code, as long as the source to get down, you can extract the desired message Crawler process: Want the site's server to send a request, the return of the response body is the source code of the Web page. ? ==>1, the construction request is sent to the server ===>2. Accept Response and resolve
