It is recommended that you use the Shen Archer Cloud Crawler. The crawler is completely written and executed on the cloud. There is no need to configure any development environment, and rapid development and implementation are possible.
A complex crawler can be implemented with just a few lines of javascript, and it also provides many functional functions: anti-anti-crawler, js rendering, data publishing, chart analysis, anti-leeching, etc. These problems that are often encountered in the process of developing crawlers are all solved by Archer will help you solve it.

The python crawler is used to "copy" the resources of a website, which is to download a website and the hyperlinks on the website. How to use it. . . It depends on how you made it up. . Generally, it is just a matter of setting the URL to be crawled and the download location. . There are many principles, the most common one is deep search and wide search Deep search means to go to the end of the first chain first, and then backtrack to take the branch Guang search means to traverse the first layer first, and then traverse the second layer ...
Python has little to do with crawlers One is a language and the other is a data crawling tool that uses Internet hyperlink technology The premise for everyone to mention python crawlers is 1) python is relatively simple 2) There are mature python-based implementations crawler framework But the two themselves have nothing to do with each other

You can implement crawlers in any language, python has a more convenient framework
