operation result:

Note: If you repeatedly crawling with a cookie and a ip, will be Taobao anti-climb limit, let slip verification, this time you do not want a solution to this slide verified, the case will be empty crawling data to appear, because you get to the page is sliding to verify web page. My approach is to take the time to climb down the page stored in a text file which, when debugging code and then read that file directly from the web page code on the line, so you do not need to repeatedly crawling up. It posted the above code is the final code after I debugging.
