从android发送oauth令牌原因KeyNotFoundException

2012-05-18 47 views

我们目前正在使用DotNetOpenAuth库通过OAuth来保护wcf SOAP web服务的应用程序正在删除。整个事情在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。然而，从android平台调用服务会导致一些hickup。有时它会运行得很好，有时它会引起异常，说“序列不包含任何元素”。从android发送oauth令牌原因KeyNotFoundException

不幸的是我没有所有的细节，因为我自己实际上并没有可用的android。但是，在阅读由我的同事创建的日志文件时，有几件事情脱颖而出。

Windows事件日志表明这是一个KeyNotFoundException，这是因为令牌被识别而发生的（令牌，实际上，是存在于数据库中，所以这不应该发生 - 我已经检查过）。

此外，真正有趣的是，只有在oauth_token参数中存在+或/符号时才会发生此异常。我有点倾向于认为这是一个编码问题，其中两个字符编码不正确。在检查Windows事件日志时，只要oauth_token参数包含+或/，它将被空格替换。然而，我不知道这是在哪里编码，为什么这两个字符被替换为一个空间，最重要的是现在，如何解决它。

我也启用了log4net logging，它显示oauth_token变量与数据库中的内容相同。但是，它显示构建的签名基本字符串以包含oauth_token，只有/字符被替换为％252F。然而，稍低几行，oauth_token变量单独显示（即不是作为基本字符串的一部分，而是变量的摘要），并且其中的/实际上显示为/。

任何有关这个问题的帮助将不胜感激。

检索我们会需要对异常的调用堆栈肯定知道。可能这个异常只是一个内部异常（ASP.NET有习惯报告内部异常而不是外部异常），并且外部异常可能会添加我们需要的上下文。既然你已经enabled logging，我希望你应该能够从那里获得所有的异常细节。

如果/和+字符未在HTTP URL中进行编码，那么应该修复客户端中的错误。

我已经添加了log4net文件 - 或者至少，大部分。不幸的是，整个事情太大而无法发布（超过30000个字符）。希望这可以揭示一些事情。 – Nico

啊，看来我们已经找到了解决办法。你是对的，这是客户端的一种编码。基本上，通过使用java.net.URLEncoder，问题就解决了 - 即使在oauth_token包含'+'或'/'时，从android平台发送调用时也不会出现更多异常。 – Nico
