1. Limit the access frequency of IP, crawler websites will increasingly use anti-crawler technology, of which the most commonly used is to limit the number of visits to ip.

If the local ip address is blocked by the site, maybe you can try to use the proxy IP to continue crawling.

2. Improve the efficiency of crawling.

It is also possible that when crawling with a single crawler, the crawling speed will be very slow, and the efficiency of a single crawler has no advantage compared with the efficiency of individual manual crawling. To improve the efficiency of crawling, use multiple crawlers, which requires configuring ip for each crawler and rotating IP. At this point, you need to use the proxy IP.
