ngix重定向到ubuntu服务器中的非www

Question

我看到了许多解决方案，但对我来说却无济于事。我正在尝试将用户从www重定向到非www url。这是我正在使用的服务器代码

 server {
    if ($host = https://www.example.com.com) {
        return 301 https://example.com.com$request_uri; // IT DOESN'T WORK
    } # managed by Certbot



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


    if ($host = example.com.com) {
        return 301 https://example.com.com$request_uri;
    } # managed by Certbot
        listen 80;
        server_name example.com.com www.example.com.com;
    return 404; # managed by Certbot
}
