我正在使用facebook登录我的一个网络项目，我使用以下设置创建了我的应用程序：
app domain - dev.aval-api.appspot.com
Site URL - http://dev.aval-api.appspot.com/
Client OAuth Login - yes
Valid OAuth redirect URIs -http://dev.aval-api.appspot.com/
用facebook登录后点击它打开浏览器新窗口，该窗口中没有显示内容或错误。该浏览器新标签的网址如下：
https://www.facebook.com/dialog/oauth?app_id=<app_id>&client_id=<app_id>&display=popup&domain=dev.aval-api.appspot.com&e2e=%7B%7D&locale=en_US&origin=1&redirect_uri=http%3A%2F%2Fstatic.ak.facebook.com%2Fconnect%2Fxd_arbiter%2FFX-Xf5fQjUk.js%3Fversion%3D41%23cb%3Dfd02cbb44%26domain%3Ddev.aval-api.appspot.com%26origin%3Dhttp%253A%252F%252Fdev.aval-api.appspot.com%252Ff13c5337a8%26relation%3Dopener%26frame%3Df11297078&response_type=token%2Csigned_request&scope=basic_info%2Cemail%2Cuser_birthday%2Cuser_likes%2Cuser_relationships%2Cuser_photos%2Cpublish_stream&sdk=joey
