This article mainly introduces the relevant knowledge of Python to implement asynchronous proxy crawlers and proxy pools. It has a very good reference value. Let’s take a look at it with the editor. Using python asyncio to implement an asynchronous proxy pool, crawl the proxy according to the rules. Free proxies on the website are stored in redis after verifying their validity. The number of proxies is regularly expanded, the validity of proxies in the pool is checked, and invalid proxies are removed. At the same time, a server is implemented using aiohttp, and other programs can obtain the proxy from the proxy pool by accessing the corresponding URL. Source code Github environment Python 3.5 + RedisPhantomJS (optional) Supervisord (optional) Because the code uses a lot of asyncio's async and await syntax, which are only provided in Python 3.5, so it is best to use Python 3.5 and above. Version, I am using Python3.6. Dependence on redisaiohttpbs4lxmlrequestsseleniumselenium package is mainly used to operate PhantomJS. Below

##Introduction: Preface A proxy pool project is maintained on GitHub. The source of the proxy is to crawl some free proxy publishing websites. In the morning, a guy told me that one of the proxy capture interfaces was unavailable and returned status 521. I ran through the code with the mentality of helping people solve problems. Found this to be the case. Through Fiddler packet capture comparison, it can be basically determined that JavaScript generates encrypted cookies that cause the original request to return 521.
