More and more websites are integrating Cloudflare, standardizing anti-scraping mechanisms and enhancing reusability. Cloudflare's anti-scraping approach can generally be divided into two categories: browser environment validation via JavaScript execution and TLS/HTTP/2 fingerprint verification.

越来越多网站接入Cloudflare，反爬终于实现了标准化，并得到很好的复用。根据Cloudflare反爬思路，大概分为两种：一是检测浏览器环境，要求执行JS验证环境后放行，另一类是验证TLS指纹和HTTP/2指纹。
