This article mainly introduces "what is the crawler agent ip anti-crawling procedure flow". In the daily operation, I believe that many people have doubts about what the crawler agent ip avoids the anti-crawling program flow is. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "what is the crawler agent ip avoidance anti-crawling program flow?" Next, please follow the editor to study!

How can a crawler safely avoid the anti-crawling process? With the rapid development of Internet technology, people have already entered the Internet era, the embodiment of this period has already penetrated into various manufacturing industries, and continue to form new business circles.

During big data's time, whether or not Internet companies began to collect and analyze big data, created their own large database queries, and then spawned thousands of data collection companies, namely Internet crawlers and web spiders.

1. Crawler staff seems to have become a key position in big data, an Internet technology company.

They should not only be proficient in web crawlers and analysis, but also understand Baidu search engine and related search optimization algorithms, and must master operating memory, characteristics and distributed system optimization algorithms. The working system process edits effective and reasonable layout.

2. Now for the crawler, how to safely avoid the crawler process is a very wide range of requirements.

To put it simply, the application proxy server is like a road bridge in the middle, which allows customers to choose only ip classes according to their own requirements. It must be simple and practical, and can maintain the continuous conversion of their own network ip to achieve the purpose of all normal crawling information content.

But generally speaking, the crawler manufacturing industry has encountered the following two problems in Guangzhou: the crawler customers themselves do not have the ability to maintain the server or win the ip agent. First, the content of science and technology is high, and second, the cost is high. The cost of self-driving travel server is too high, dozens of servers calculate tens of thousands of yuan per month. In addition, the management method server must be a technical professional operation and maintenance personnel. In addition, according to each dial-up server, the crawling efficiency is too low, c # multi-thread can not actually operate, dial-up ip in some areas can not be collected.

Web crawlers must use a large number of proxy IP when collecting data. Without an IP agent, it is certainly impossible to raise the IP limit and collect a large amount of data information. Only the initial data information collection is not only time-consuming and laborious, but also the actual effect is not very good. High-quality distributed system agent ip has also become a rigid requirement of crawler manufacturing industry.

At this point, the study on "what is the crawler agent ip avoidance anti-crawling procedure" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
