NGINX跨域配置

在nginx.conf中配置

http {
  ......
  add_header Access-Control-Allow-Origin *;
  add_header Access-Control-Allow-Headers X-Requested-With;
  add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
  ......
}

这样就可以实现GET,POST,OPTIONS的跨域请求的支持
也可以 add_header Access-Control-Allow-Origin http://test.51testing.com; --指定允许的url;

http {
  ......
  add_header Access-Control-Allow-Origin *;
  add_header Access-Control-Allow-Headers X-Requested-With;
  add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
  ......
}
