This article mainly introduces "does the crawler program have to use the proxy IP?". In the daily operation, I believe that many people have doubts on the question that the crawler program must use the proxy IP. The editor consulted all kinds of materials and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "must the crawler program use the proxy IP?" Next, please follow the editor to study!
First, when crawling, the crawled website has an anti-crawler mechanism.
If you use an IP to visit a web page repeatedly, it is easy to have IP restrictions, and you can no longer visit the site, so you need to use a proxy IP.
Second, crawlers are likely to be blocked when grabbing website data.
Replace different IP with proxy IP, and each other's website is considered to be a new user, of course, there is no risk of hackers.
Third, if the amount of work is large and the crawling speed is fast, the target server is easy to find, so it is necessary to use proxy IP instead of IP before crawling.
The proxy IP replaces the real IP. Web crawler is a program for grabbing data, proxy IP is not a necessity for web crawler work, but proxy IP is a tool for crawler work to improve efficiency and facilitate work. Network work is very fastidious about speed, under the premise of high efficiency, tools can improve their work quality and efficiency, which is the significance of the existence of agent IP.
Therefore, in order to effectively break through those anti-crawler mechanisms and continue to crawl at high frequency, a high-quality proxy IP is still needed.
Do web crawlers have to use proxy IP? The answer is actually no, but a proxy IP must be used in the above cases.
At this point, the study on "does the crawler have to use proxy IP" is over. I hope to be able to solve everyone's doubts.
