- Use Python to crawl the entire video information of station B
- I think everyone is familiar with Station B. In fact, there are a lot of crawlers on Station B. However, what I read on paper is ultimately shallow, and I definitely know that I have to do it in detail, so I am here. In the end, the total amount of data crawled was 7.6 million. To prepare, first open Station B, find a video on the homepage and click on it. For normal operation, open the developer tools. This time, the goal is to obtain video information by crawling the API provided by station B without parsing the web page. The speed of parsing the web page is too slow and the IP address is easily blocked. Check the JS option, refresh with F5 and copy the address of the api found, remove unnecessary content, and get https://api.bilibili.com/x/web-interface/archive/stat?aid
