我试图将www请愿重定向到非www域，我尝试了每个人都说的建议，但对我不起作用，这是我的nginx配置文件：

server {
    listen 80;
    server_name www.site.com;
    return 301 $scheme://site.com$request_uri;
}
server {
            listen 80;
            server_name _;
            return 301 https://$host$request_uri;
}
server {
        listen 443 ssl;

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

        server_name site.com;
        ssl_certificate /etc/nginx/ssl/site.com/site.>
        ssl_certificate_key /etc/nginx/ssl/site.com/myserver.key;
        ssl_prefer_server_ciphers on;

        location / {
                try_files $uri $uri/ =404;
        }
}
