从android发送oauth令牌会导致KeyNotFoundException

我们目前正在删除一个应用程序，该应用程序使用DotNetOpenAuth库通过OAuth保护WCFSOAPWeb服务。整件事都在IIS7上运行。web服务和DotNetOpenAuth库运行平稳，至少在PC上运行时是如此。但是，从android平台调用该服务会导致一些问题。有时它运行得很好，有时它会导致异常，说“序列不包含元素”

不幸的是，我没有所有的细节，因为我自己实际上没有安卓系统。然而，在阅读同事创建的日志文件时，有几件事很突出

Windows事件日志表明这是一个KeyNotFoundException，发生这种情况是因为令牌被识别（事实上，令牌存在于数据库中，所以不应该发生这种情况-我已经检查过了）

此外，真正有趣的是，只有当oauth_令牌参数中存在+或/符号时，才会发生此异常。我倾向于认为这是一个编码问题，两个字符没有正确编码。检查Windows事件日志时，只要oauth_令牌参数包含+或/，它就会被空格替换。然而，我不知道这是在哪里编码的，为什么这两个字符被替换为一个空格，最重要的是，现在，如何修复它

我还启用了log4net日志记录，这表明oauth_令牌变量与数据库中的内容相同。但是，它确实显示构造的签名基字符串以包含oauth_标记，只有/字符被替换为%252F。然而，在下面几行中，oauth_标记变量单独显示（即不是作为基本字符串的一部分，而是在变量摘要中），并且在那里/实际显示为/

在此问题上的任何帮助都将不胜感激
