Android C2DM使用基于java的Web服务，但如果我尝试使用基于WS-dotNet的Web服务，就会出现401错误

我用Java做了一个简单的Web服务，并在JBoss5.1中部署了它。 此WS处理向Android手机发送通知消息的C2DM服务。我在谷歌c2dm api中设置了所有类似于红色的内容，首先，我注册了c2dm服务。在这种情况下，一切都很好

现在我必须在IIS7上的.NET中执行同样的操作。有关.Net代码的一些说明：

• WebService提供setRegId（）和pushMessage（）方法

• 在设置字符串“reg_id”和“device_id”后，setRegId（）只需调用handShakeRegId（）

• 所有注释的代码都是我试图解决的问题，但都是无用的

这就是代码：

• 握手法效果很好！我可以毫无问题地获得身份验证令牌
• setRegId方法由Android设备调用（在我的例子中是Android+GoogleApi 2.2模拟器）

pushMessage getResponse（）中出现的错误总是相同的（这很奇怪，因为我实现的连接与握手方法中的连接完全相同：-/）：

System.dll中发生了类型为“System.Net.WebException”的第一次意外异常 （pushMessageMsgIN）错误：System.Net.WebException:远程服务器错误（401）在System.Net.HttpWebRequest.GetResponse（）中未经授权

搜索有用的东西需要2天，但是。。。。没有什么！！ 这很有压力

我希望有人能帮助我

---

我对IIS中的身份验证有所了解，所以我启用了匿名用户和其他未知的东西，只是为了尝试。没什么

解决：我的愚蠢！！！我在私有字符串源代码中犯了一个错误！！我指定了一个错误的包名！--

Heeeelpppp！！！！！！！！！！！！没有人能帮我。uffffi假设您将您的身份验证令牌存储在某处。你不能就这样引用。当您调用pushMessage（）时，我假设您的身份验证令牌为空。已解决：我的愚蠢！！！我在私有字符串源代码中犯了一个错误！！我指定了一个错误的应用程序包名称！哈亚：）
