NGINX 反向代理无法使用 www url

Question

我在 Cent OS 7 上设置了反向代理，它运行良好，但我刚刚注意到的问题是，如果你访问www.foo.foo.com但可以访问 foo.foo.com。

我的配置如下：

foo.foo.com.conf

     server {
    server_name foo.foo.com;
    set $upstream 10.10.1.12:8012;

    location / {
    proxy_pass_header Authorization;
    proxy_pass https://$upstream;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_http_version 1.1;
    proxy_set_header Connection "";
    proxy_buffering off;
    client_max_body_size 0;
    proxy_read_timeout 36000s;
    proxy_redirect off;
    }


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/foo.foo.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/foo.foo.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


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


    server_name foo.foo.com;

    return 404; # managed by Certbot


}

www.foo.foo.com.conf

     server {
    server_name www.foo.foo.com;
    set $upstream 10.10.1.12:8012;

    location / {
    proxy_pass_header Authorization;
    proxy_pass https://$upstream;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_http_version 1.1;
    proxy_set_header Connection "";
    proxy_buffering off;
    client_max_body_size 0;
    proxy_read_timeout 36000s;
    proxy_redirect off;
    }


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/foo.foo.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/foo.foo.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


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


    server_name www.foo.foo.com;

    return 404; # managed by Certbot


}

}

我的问题是如何使用 www. 而不是使用 www. 来解析反向代理？我尝试为每个域创建 2 个 .conf 文件，例如一个 foo.foo.com.conf 和一个www.foo.foo.com.conf但这似乎不是解决问题的正确方法，因为问题并没有得到解决。
