This article introduces the relevant knowledge of "Does crawler need to use proxy IP?" In the operation process of actual cases, many people will encounter such difficulties. Next, let the editor lead you to learn how to deal with these situations! I hope everyone will read it carefully and learn something!
Many people think that the work of crawlers and proxy IP are inseparable, and crawlers must use proxies. This is not the case. Crawlers do not need proxies. In essence, crawlers just imitate users who visit websites. For servers, such special users often do not follow the rules, increasing the pressure on the server, so websites are always discovered and banned in various ways.
1. The business volume is very small.
Sometimes small crawling work can be completed without the use of proxy IP. For example, crawling hundreds of articles can be easily solved by using a locomotive. Or if the work efficiency is not high, you can simulate the normal manual access speed and crawl slowly.
2. The anti-climbing strategy is weak.
Some websites do not have anti-crawler strategies, and the crawler can work normally without proxy IP, but it is recommended not to be too reckless to avoid crashing the website server; some websites have weak anti-crawler strategies, and the crawler can work normally without proxy IP.
3. Low access frequency. The most common anti-crawler strategy is to determine the access frequency of a single IP, because ordinary users do not visit web pages very frequently.
You can choose to avoid being discovered by the server by reducing the access frequency, but if the crawler is similar to the access frequency and logic of ordinary users, then there is no point in crawling.
