Nginx：通配符server_name

Question

我无法忽略自己网址中的 www 。

我有一个* .example.com通配符SSL证书
我的服务器应仅响应https://randomSubDomain.example.com
并忽略https://www.randomSubDomain.example.com。

我的SSL证书仅对https://randomSubDomain.example.com有效
不是https://www.randomSubDomain.example.com

这是我的Nginx服务器文件

server {
    listen 80;
    listen [::]:80;
    server_name *.example.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name *.example.com;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    root /var/www/example;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ \.php$ {

        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /\.(?!well-known).* {
        deny all;
    }
}
