http - nginx 将所有 http 重定向到 https

Question

我正在尝试将所有网站流量重定向到 https://example.com。 我要:

https://example.com
https://www.example.com
http://example.com
http://www.example.com
example.com
www.example.com

to all redirect to `https://example.com`

现在，如果我直接输入 https://example.com，就可以了。

但是，如果我输入非 SSL example.com 或 www.example.com 或 http://example.com或 http://www.example.com ，我得到这个错误:

This site can’t be reached
vinnect.com refused to connect.
Search Google for vinnect
ERR_CONNECTION_REFUSED

我认为我需要修复我的 nginx，如下所示。

Answer 1

在您的代码中，您必须将两个服务器分开。将端口 80 或 http 放在服务器子句中，将 https 放在另一个服务器子句中。 由于 return 301 https://$host$request_uri; 行，将发生重定向。它应该在 http 部分而不是 https。 查看您的配置，我注意到最后三行正在检查非 https 请求并使用相同的方法将用户重定向回 https。我从未尝试过，但它可能会奏效，因为 Cerbot 的人知道他们在做什么。
