如何在 nginx 中将 www 重定向到非 www

Question

这是我当前的 nginx 配置：

server {
        server_name mydomain.com www.mydomain.com;

        listen 443 ssl;
        ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem;
        include /etc/letsencrypt/options-ssl-nginx.conf;
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}

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

        if ($host = mydomain.com) {
            return 301 https://$host$return_uri;
        }

        server_name mydomain.com www.mydomain.com
        listen 80;
        return 404;
}

这很好用，但我也需要将 www 重定向到 non-www。怎么做？

试试这个：

location / {
  if ($http_host ~* "^www.example.com"){
    rewrite ^(.*)$ https://example.com/ redirect;
  }
}
