Android C2DM 可与基于 java 的 Web 服务配合使用，但如果我尝试使用基于 WS dotNet 的 Web 服务，则会出现 401 错误

Question

我用 Java 做了一个简单的 Web 服务，并将其部署在 JBOSS 5.1 中。 该 WS 处理 C2DM 服务，用于向 Android 手机发送通知消息。我在 google c2dm api 中将所有内容设置为红色，首先，我注册访问 c2dm 服务。在这种情况下，一切正常。

现在我必须在 IIS7 上的 .NET 中执行相同的操作。关于 .Net 代码的一些说明：

• setRegId() 和 PushMessage() 方法可通过 WebService 获得。

• 在设置字符串“reg_id”和“device_id”后，setRegId() 会简单地调用

• < p>所有注释的代码都是我解决问题的尝试，但都没有用

这就是代码：

• 握手方法有效 出色地！我毫无问题地获得了身份验证令牌。
• setRegId方法由Android设备调用（在我的例子中是Android+GoogleApi 2.2模拟器）

在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“System.Net.WebException”类型的第一次机会异常 (pushMessageMsgIN) 错误：System.Net.WebException：远程服务器错误 (401) 在 System.Net.HttpWebRequest.GetResponse() 中未经授权

2 天搜索有用的内容，但是......没有！ 压力很大...

我希望有人能帮助我。

我在 IIS 中红色了有关身份验证的内容，因此我启用了匿名用户和其他未知的内容只是为了尝试。没有什么！
