Nginx 将 certbot www 重定向到非 www

Question

我正在尝试将 HTTPS www 请求重定向到非 www，但无法正常工作。我需要更改哪一行代码才能实现重定向？

server {
    root /var/www/mydomain.com/html;
    index index.html index.htm index.nginx-debian.html;

    server_name mydomain.com www.mydomain.com;

    #gZip stuff here...
    #Certbot stuff here...
}

server {
    if ($host = www.mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    if ($host = mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80;
    listen [::]:80;

    server_name mydomain.com www.mydomain.com;
    return 404; # managed by Certbot
}

我建议使用下面提到的管理方式。根据 Nginx 文档，这也是他们处理域级重定向的推荐方式。

server {

        listen 443; 
        server_name www.example.com;
        return 301 $scheme://example.com$request_uri;
    }

    server {

        listen 443;
        server_name example.com;

         root /var/www/mydomain.com/html;
         index index.html index.htm index.nginx-debian.html;

        # Others Configuration...

    }

如果需要，您还可以添加一个服务器块以将 HTTP 重定向到 https。

server {

        listen 80;
        server_name www.example.com example.com;
        return 301 https://example.com$request_uri;
    }
