XMLHttpRequest cannot load http://xx.xx.net/user/m. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://localhost:8081' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.
这个是因为你调用的CGI的回包没有加允许跨域的头吧
附上不同版本的图，新版的发送了options请求之后就不再发送post请求了，而且这个功能在线上是没问题的，所以应该是最新微信web开发者工具的bug
最新版（0.15.152900）的有跨域BUG
怎么回事呢，如何解决的，害的我一直用的老版本的工具

在0.7版本的微信开发工具 中是可以的，在0.15版本中不正常。
