Django Python社交身份验证，身份验证被Facebook应用程序取消

Question

我正在尝试使用Facebook凭据实现网站登录。当我在Facebook小部件上按“取消”或“确定”时，我会看到不同的反应。当我按Cancel时，我看到以下内容

    Environment:

这是可预测的。但是当我按OK时，我看到另一个错误。

我在本地运行的网站Ubuntu 14.04 apache Web服务器与80端口。我怀疑错误的Facebook应用程序设置，但不知道调试什么。

此外，我可以提到推特登录也在相同的设置下工作。

请指教！

Answer 1

检查重定向URL。在发出post请求时，我错误地指定了重定向URL和客户端ID。对于Facebook，重定向URI是可选的。试着去掉它，它会很好的工作。

Answer 2

我做了错误的Facebook应用程序设置。在安全/服务器IP白名单中，我127.0.0.1地址。删除此地址后，问题就消失了（空格可以）。
