This article mainly introduces "why the domestic free proxy server ip is competent for the crawler work". In the daily operation, I believe that many people have doubts about why the domestic free proxy server ip is competent for the crawler work. The editor consulted all kinds of information and sorted out the simple and easy-to-use operation methods, hoping to help you answer the question "Why the domestic free proxy server ip is competent for the crawler work"! Next, please follow the editor to study!

In order to ensure the normal operation of the server, site maintenance personnel often restrict some abnormal users. What is an exception user? There are also some anti-human access behaviors, such as visiting dozens of pages a second. Crawlers usually make more effort, usually visit dozens of pages a second, and need the help of a proxy server.

1. In order to save costs, many people first use crawlers to climb a bunch of free proxy servers on the Internet.

And then use this bunch of free proxy servers to do crawler work. At the end of the day, they found that they had accomplished very little, 18000 miles short of their goal. What happened? That is because the quality of the free proxy server is very poor, which is mainly reflected in three aspects: card, instability and low concealment.

2. Due to the limited resources of the proxy server.

The users who use the free proxy server are not restricted, which makes the free proxy server very stuck and unable to improve work efficiency. Similarly, due to the large number of users using free proxy servers, there are often users who preempt a lot of resources, which also leads to the instability of free proxy servers, often unable to connect and unable to continue crawlers.

3. Most of the free proxy servers are transparent and have the characteristics of ordinary agents, so they are easy to be identified by crawlers and the transaction success rate is low.

In short, free proxy servers are not suitable for crawlers. If you are just debugging your code, you can give it a try. If there is crawler work, it is recommended to buy a paid proxy server, high speed and stability, high success rate, greatly improve the work efficiency.

At this point, the study on "why the domestic free proxy server ip is competent for crawler work" is over. I hope to be able to solve everyone's doubts.
