This article mainly explains "how to solve the problem of limited crawling of crawler programs". The content of the explanation in this article is simple and clear, and it is easy to learn and understand. let's study and learn "how to solve the problem of limited crawling of crawlers".

1. Slow down the grasping speed. Try to simulate the behavior of actual users, the pressure of the target website is relatively reduced, but the efficiency of data capture is also reduced accordingly.

2. Set proxy IP.

The crawler requires multiple stable proxy IP, and each time the proxy IP is used to replace the IP address, the target site is treated as a new user, so there is no danger of blocking.

The above are the most commonly used solutions for crawler IP restrictions, and I hope they will be helpful to you.

Web crawler is the mainstream way to get Internet big data, but when getting information, the information captured is different from the information displayed by the target site, or blank information is captured, so it is likely that your IP address is limited by the target site.

In most cases, the IP address is the basis of the website anti-crawling mechanism. When we visit the website, our IP address will be recorded. If the crawling frequency is higher than the limit threshold of the target site, the server you treat as a crawler, restricting your access.
