Recommended 7 articles for Agent pool

This paper mainly introduces the Python implementation of asynchronous agent crawler and the relevant knowledge of the agent pool, with a good reference value, followed by a small series to see it? Using Python Asyncio to implement an asynchronous agent pool, according to the Rules crawl Agent website free agent, After verifying that it is valid, in Redis, periodically expand the number of agents and verify the validity of the agents in the pool, removing the failed agents. At the same time, a server is implemented with Aiohttp, and other programs can obtain proxies from the agent pool by accessing the appropriate URLs. SOURCE GitHub Environment Python 3.5+REDISPHANTOMJS (optional) Supervisord (optional) because Asyncio's async and await syntax is heavily used in the code, They are provided in Python3.5, so it's best to use Python3.5 and above, and I'm using Python3.6. The dependency Redisaiohttpbs4lxmlrequestsseleniumselenium package is primarily used to manipulate PHANTOMJS. Below

2. Graphic details python crawler crack JS encrypted cookie step

Introduction: The preface maintains a proxy pool project on GitHub, and the proxy source is to crawl some free agent publishing sites. I had a little brother in the morning telling me that there was a proxy fetch interface is not available, return status 521. With the help of people to solve the problem of the mentality to run over the code. 　　Found it to be so. By comparing the Fiddler capture package, it is basically possible to determine that JavaScript generates an encrypted cookie that causes the original request to return 521.
