为什么.cf、.tk 的域名，在 cloudflare 不能套 cdn

This topic created in 927 days ago, the information mentioned may be changed or developed.

同样的 .com 域名，套 cloudflare 一切正常。但是 .cf 或 .tk 域名，就不行了。用 curl 后，发现总是收到 301 。
response 信息如下：

解决问题了，cloudflare 的配置问题：

SSL/TLS --> Overview --> 由 “Flexible” 改为 “Full ( strict )”，解决问题。

这是 nginx 配置问题吧，nginx 返回了 301 啊，location 是不是你旧网址

直接 curl 我的 ip 没问题。套 cf 就完蛋。

@paranoiagu 不要只 curl ip ，要带上域名

@Conantv2 带上了，不知道这样带上对不对。

这么看，直接访问倒不会 301 ，你看下日志吧，可能是日志带了某个参数触发的 301

@Conantv2 我也感觉是 nginx 的问题了。我再研究一下，谢谢。

为什么我托管的网页由 full strict 改为 flexible 才能正常打开

kingwrcy

Nov 22, 2023

full strict 是 cf 到你的源站也是 https,要求你的源站支持 https.
flexible 是 cf 到你的源站是 http

你源站域名没有 https 的话,需要改成 flexible. 不然就是无限 301
