Explain some anti-climbing mechanism! Few people will use big data technology and will not come into contact with crawlers, so be sure to use proxy ip to solve this problem. When obtaining web page data information from the target website, we will encounter the anti-crawling mechanism of the other server.

What do we encounter when collecting the agent ip crawler?

1. When visits are too frequent, ip is suddenly unable to access.

In this example, the target site has a reverse crawling mechanism, and when the access frequency touchscreen reaches the set threshold ip, access is prohibited. Therefore, when we use proxy ip, we should slow down as much as possible and don't wait until it is blocked by the other party.

2. When the proxy ip starts to be used, it is disabled and cannot be accessed, in which case the user usually gets the ip and the same ip, and forbids the threshold value of the target server.

Most users will choose to share ip pools with a large number and reasonable price, so they can switch ip directly in this case.

Some users will think that you can simply use the proxy ip without being disabled or disabled, which is wrong. The proxy ip, like the native ip, needs to be used with care.
