我如果在同源网页浏览器上 fetch 是可以正常返回结果的，但是我放到 jetbrains 客户端的 http 请求上执行就返回 403forbidden 了
下面是我的请求内容：
GET https://www.nodeseek.com/api/attendance/board?page=30

下面是返回的网页内容：

很多特征可以检测，例如浏览器指纹

CF 防守的判断原理基本就同 @jinliming2 所言检查 TLS 指纹以区别浏览器和其他库。
解决方法比如 curl 则用特供版 https://github.com/lwthiker/curl-impersonate 🔗 测试直接执行： ```bash curl_chrome116 https://www.nodeseek.com/api/attendance/board?page=30 ``` 可以得到 JSON 结果，因而确为前述原理，没有常规请求头检查。 |

cf 判断没那么简单的，比如可以根据你这个网站常用的用户行为来判断，行为异常就直接弹质询框，反正正常用户也不会受影响
