This article mainly shows you "Why Python crawler data collection must use proxy technology", the content is easy to understand, clear, hope to help you solve your doubts, the following let Xiaobian lead you to study and learn "Why Python crawler data collection must use proxy technology" this article.

1. It can help individuals and businesses make plans for the future and provide users with a better experience. So data collection is a very important task.

This is a lot of complex data. When distributed on different sites, relying on people to collect crawling is not practical, too slow, not in line with the current work efficiency.

2. The Python crawler needs to crawl data on the network 24 hours a day. In this way, high-frequency access to the data of the target website will trigger the protection of the server and limit the crawler's network IP address, also known as IP packet processing.

The proxy IP is like a mask to hide the real IP address. But this does not mean that the proxy IP is fake and does not exist. In fact, the IP address of the agent is a real online IP address. Therefore, there may be problems with real IP, and proxy IP may also occur, such as network delay, disconnection, etc.; therefore, we need an alternate IP address to replace it, because crawlers usually have a lot of data to crawl and need a lot of alternate IP addresses.

The above is all the content of the article "Why Python crawler data collection must use proxy technology". Thank you for reading!
