如果想要301你可以跟我 一样设置两个server段即可
server{
      listen 80;
      server_name znsj8.com www.znsj8.com;
      return 301 https://www.znsj8.com$request_uri;
   }
server
{
    listen 443 ssl http2;
  server_name mrhee.com www.znsj8.com;
    add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
