交易谷歌的oauth2代码的OAuth2令牌中的ASP.NET

我已经检查计算器和尝试了几种解决方案，但我仍然得到400试图使一个POST请求谷歌令牌服务器，交易代码为的oauth2令牌时。该代码正在从查询字符串中正确检索。我已尝试使用URL编码秘密，重定向URL并将请求上的编码更改为ASCII。我知道，谷歌是用挑剔的头，但JSON响应是故意含糊不清，仅返回“错误：错误的请求”我不能调试什么是错的请求。我也尝试在Chrome REST客户端中测试发布请求并收到相同的错误。我认为在头文件中有一个错误或者其他一些格式问题，但是Google没有返回有用的错误代码。交易谷歌的oauth2代码的OAuth2令牌中的ASP.NET
