允许全部把域名改*

server {  listen       22222;  server_name  localhost;  location  / {  if ($request_method = 'OPTIONS') {  add_header Access-Control-Allow-Origin 'http://localhost:8080';  add_header Access-Control-Allow-Headers '*';  add_header Access-Control-Allow-Methods '*';  add_header Access-Control-Allow-Credentials 'true';  return 204;  }  if ($request_method != 'OPTIONS') {  add_header Access-Control-Allow-Origin 'http://localhost:8080' always;  add_header Access-Control-Allow-Credentials 'true';  }  proxy_pass  http://localhost:59200;   }  
}

或者

server {  listen       22222;  server_name  localhost;  location  / {  add_header Access-Control-Allow-Origin 'http://localhost:8080' always;  add_header Access-Control-Allow-Headers '*';  add_header Access-Control-Allow-Methods '*';  add_header Access-Control-Allow-Credentials 'true';  if ($request_method = 'OPTIONS') {  return 204;  }  proxy_pass  http://localhost:59200;   }  
}

完整配置，有lua
