启用了https证书访问，都是443的ssl端口，如果默认的80端口，需要跳转重定向到安全连接

方式一：301永久重定向

server {
    listen 80;
    server_name *.xxxxxxxxxxx.com;
    if ($host ~* "^(admin|wx)\..*$") {
        return 301 https://$1.xxxxxxxxxxx.com$request_uri;
    }
}

方式二：重写

server {
    listen 80;
    server_name  a..xxxxxxxxxxx.com b.xxxxxxxxxxx.com;
    rewrite ^/(.*)$ https://www.xxxxxxxxxxx.com/ last;
}
