自己使用jekyll搭建的博客，评论系统使用的多说，可它今天出问题了：
XMLHttpRequest cannot load http://andyliwr.duoshuo.com/api/threads/listPosts.json?thread_key=%2F2016%2…site_ims=××××810542&referer=http%3A%2F%2Fwww.andylistudio.com%2F&v=16.6.16. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://www.andylistudio.com' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.
