This article mainly introduces "how to make the IP address unrestricted". In the daily operation, I believe many people have doubts about how to make the IP address unrestricted. The editor consulted all kinds of materials and sorted out a simple and useful method of operation. I hope it will be helpful to answer the doubt of "how to do it so that the IP address is not restricted". Next, please follow the editor to study!

1. Reduce the number of visits to the website. The main time of a single crawler is spent waiting for a response to the web request, which can reduce the number of page visits, reduce the workload, reduce the pressure on the website, and reduce the title risk. The first thing to do is to optimize the process, simplify the process as much as possible, and prevent repeated acquisition of multiple pages. Then repetition is also a very important method, usually based on url or id, so that those who have climbed no longer climb.

2. Even if distributed crawlers use various methods, the number of web pages that can be crawled per unit time is still limited. In the face of a large number of web page queues, it takes a long time to calculate. In this case, the machine must be replaced with time, which is the distributed crawler.

Distribution is not the essence of a crawler, nor is it necessary. For tasks that are independent of each other and have no communication, you can assign tasks manually and then execute them on multiple machines, reducing the workload of each machine. However, if there is a need for communication, such as a crawl that needs to be changed, this column changes each time, even if the split task is cross-repeated, because each machine has a different crawl column while the program is running-in this case, only distributed can be used.

3. Proxy IP can also improve access speed. Each proxy server generally sets up a large hard disk buffer, which can save information in the cache area, which is convenient for users to extract directly from the cache area. If you use high-hiding proxy IP, you can better disguise IP addresses and have high security, which can not only prevent IP from being blocked, but also protect personal privacy.

At this point, the study of "how to make the IP address unrestricted" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
