NGINX 支持子域名和普通域名

虽然不是 NGINX 专家，但我已做出我认为有效的更改。这是 PROD 服务器，因此不要只是将其推送到它并希望获得最佳效果。

我想要做的是让子域名和域名都重定向到各自的页面。例如，当有人输入https://example.com我需要它来做https://example.com当有人进入时https://learning.example.com我需要它去https://learning.example.com最后当有人进入https://www.learning.example.com我需要服务器重定向到https://learning.example.com.如果这一切都有道理的话。

我相信下面的代码（但可能是错的）应该可以工作，但如果有人能审查它并修复可能导致的潜在问题，我将不胜感激。

你的第二个区块有错误server。

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name www.example.com;
    ...
    return 301 https://$host$request_uri;
}

$host在这种情况下将解析为server_name，这意味着这将导致重定向循环。

要从www.前缀重定向到没有前缀的主机，您需要使用正则表达式server_name：

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name ~^www\.(?<domain>.+)$;

    ...
    return 301 https://$domain$request_uri;
}

正则表达式用于捕获裸域名，然后发出到实际域的重定向。
