关于Nginx-Cloudflare配置参数求解

[despire1119]

对文档中“跳转域名”和“直连域名”的定义以及cloudflare归属有点疑问：

1. cf_redirect_host 是否就是我cloudflare内的域名？
2. cf_direct_host 是否就是我本机局域网IP+端口？
3. 我的域名归属于万网，DNS解析挂的Cloudflare，是否可以直接使用？还是需要把域名归属转移到Cloudflare？（好贵...）

谢谢

这两个都填写为您域名下的子域名，按照示例文件操作即可。
不需要转移注册商。

另外，非 bug 问题不在 issue 板块下讨论，已转移至discussion 板块。

Sorry，再自罚一杯。

另外，我的配置几乎全部生效了，Cloudflare也看到了感人的解析记录。最后一个小问题:
Setting [ nas.letscoding.fun ] redirecting to [ nas.letscoding.fun:18681 ], https=False...
这个输出看起来没问题，但未生效。
访问nas.letscoding.fun:18681秒开，不带端口直接访问nas.letscoding.fun则提示“响应时间过长”。

以下是详细log：

两个域名不能是相同的。
比如 cf_redirect_host 填 hello.letscoding.fun （这个域名指会向CloudFlare的IP，由它提供跳转）
比如 cf_direct_host 填 nas.letscoding.fun（这个域名会指向自家IP）

访问 http://hello.letscoding.fun（不带端口号），会跳转到 http://nas.letscoding.fun:18681。
