DotNetOpenAuth和Facebook [英] DotNetOpenAuth and Facebook

问题描述

我试图用DotNetOpenAuth对一些功能的Web单点登录。

I'm attempting to use DotNetOpenAuth for some web single sign on functionality.

我拿到样品工作了谷歌和雅虎，但我与Facebook挣扎。

I got the samples working for Google and Yahoo but am struggling with Facebook.

我使用的CTP（4.0.0.11165），并在随后的这太问题

I am using the CTP (4.0.0.11165) and have followed the example in this SO question.

不过，我得到上线运行时错误：

However, I get a runtime error on the line:

IAuthorizationState authorization = client.ProcessUserAuthorization();

该错误是：

The error is:

无法获得访问令牌。授权服务器报告原因：（未知）

Failed to obtain access token. Authorization Server reports reason: (unknown)

任何想法

推荐答案

由于Facebook正在使用OAuth 2.0的旧规格您正在使用的版本是与Facebook兼容。你必须使用较早的CTP（一个具有V3.5版本）与Facebook合作。抱歉。太臭使用OAuth 2.0时，每个人都在未格式化的规范不同的草案有什么。

The build you're using is incompatible with Facebook because Facebook is using an older spec of OAuth 2.0. You have to use an earlier CTP (one with a v3.5 version) to work with Facebook. Sorry. It stinks to be using OAuth 2.0 when everyone is on a different draft of the unfinalized spec.
