我正在将dotnetopenauth与WCF服务结合使用来请求访问令牌。以下步骤没有问题：
当我尝试代表用户执行请求（获取用户的收藏夹）时，会出现问题。收到401回复，收到“错误签名”消息。
显然签名是问题，但我不知道为什么它是一个不正确的签名，因为它是由dotnetopenauth库生成的。我甚至检查了基线，看起来很好。所以有些参数必定是错误的。
可能是问题是请求完成的域。我目前在代理后面（但是将代理的ip添加到我的应用程序中允许的域列表中）？
编辑：添加了LOGS：
用户将应用程序从应用程序重定向到Twitter Auth页面，然后使用请求令牌和验证程序将其重定向到我的应用程序。然后我交换那些anaccesToken和Secret。但是当使用thos执行请求时，我得到错误'错误签名'。
