This article mainly introduces the reptiles to avoid ip blocked methods, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor with you to understand.

One of the most direct factors is that the access speed is too fast, not to mention crawling, even if users click too fast, they will be prompted to visit too often. If the access speed of web crawlers is always very fast, and they all use the same IP address, then IP will be blocked soon. Ways to prevent ip from being blocked:

1. Slow down the crawling speed.

Reduce the pressure on the target site, but reduce the number of crawls per unit time.

2. Camouflage cookies.

If you can access a page normally from the browser, you can copy the cookies in the browser.

3. Camouflage User-Agent.

Set User-Agent to User-Agent in the browser to fake browser access.

4. Use a highly anonymous agent.

To break through the anti-crawler mechanism of the website, you need to use the proxy IP and access it multiple times by changing the IP. To use multithreading, you also need a lot of IP and use highly anonymous proxies, otherwise you will be detected by the target site that you are using proxy IP and reveal your real IP, which will definitely block IP. If you use a highly anonymous agent, it's different, and the other party doesn't notice.

5. Multi-thread acquisition.

When collecting data, we all want to collect more data as soon as possible, otherwise it will be too time-consuming to collect a large amount of work one by one. For example, it can be collected once in a few seconds, about 10 times a minute, and more than 10,000 pages a day. What if it is a small website, but a large website has tens of millions of pages? It takes a lot of time to collect at this rate. It is recommended to collect a large amount of data, multi-threads can be used, and multiple tasks can be completed synchronously. Each thread collects different tasks and increases the collection quantity.

Therefore, if you do not use proxy ip, you can only extend the interval and frequency of requests during crawling, so as to better avoid being banned by the server. Of course, if you have a large number of proxy ip resources, you can easily crawl.
