已解决-感谢@MusiGenesis的坚持,我通过注册一个新的Google Mail帐户和一个新的C2DM帐户解决了这个问题.在更新了Web服务器和android应用中的相关凭据后,所有 *** 作都开始像魔术一样工作.

更新结束

我正在寻找有关发送推送通知时401未经授权错误的原因的明确列表,因此我可以尝试消除问题.

我有一个在C2DM中注册的Google电子邮件
我可以使用curl获得授权码

我的Android应用程序上有注册用户的身份验证令牌

使用2个身份验证令牌(刷新),从Web服务器发送推送通知请求时,我从Web服务器收到401未经授权的错误.

据我所知,我正在做我需要做的所有事情,因此我正在寻找自己可能缺少的东西.我搜寻了互联网,很多人似乎都遇到了同样的问题,但没有明确的答案.
任何帮助,不胜感激

更新

如下面的答案中所述,似乎需要第二阶段才能获得注册ID,该注册ID似乎与注册用户在androID应用上接收到的身份验证令牌不同.看过Jumpnote代码和这两个资源

和

除了auth令牌外,我看不到任何有关第二次注册电话以获取注册ID的信息.我显然缺少了一些东西,如果有人可以帮我说清楚,我将不胜感激.

我的C2DM接收器看起来像这样

public class C2DMReceiver extends C2DMBaseReceiver {    public C2DMReceiver() {        super(REGISTERED_Google_MAIL_ADDRESS);    }    @OverrIDe    public voID onRegistered(Context context, String registrationID)            throws java.io.IOException {        // The registrationID should be sent to your application server.        Log.e("C2DM", "Registration ID arrived!");        Log.e("C2DM", registrationID);        Intent webSeverReg = new Intent(this, RegService.class);        startService(webServerReg);         };    @OverrIDe    protected voID onMessage(Context context, Intent intent) {        Log.e("C2DM", "Message: Fantastic!!!");        // Extract the payload from the message        Bundle extras = intent.getExtras();        if (extras != null) {            System.out.println(extras.get("payload"));            // Now do something smart based on the information        }    }    @OverrIDe    public voID one rror(Context context, String errorID) {        Log.e("C2DM", "Error occured!!!");    }}

从Jumpnote应用中获取的C2DMBaseReceiver看起来像这样

解决方法:

您说您“在我的androID应用中拥有来自注册用户的auth令牌”.您可能写错了,但是从字面上看,您的意思是您使用的是注册用户的auth令牌,而不是用户从C2DM服务器获得的注册ID.

编辑：您的客户端应用程序(在设备上运行)对C2DM使用3个步骤：1)调用C2DM服务器,传递客户端的gmail帐户ID和密码,取回auth令牌； 2)使用步骤1中的auth令牌再次调用C2DM服务器,获取注册ID(ASCII溢出的96-120个字符)； 3)调用您的服务器应用,并传递在步骤2中获得的注册ID(而不是在步骤1中获得的auth令牌).

然后,当服务器应用程序想要向客户端推送内容时,它将调用C2DM服务器以获取身份验证令牌(传递用于注册C2DM服务器的电子邮件和密码,而不是客户端用户的电子邮件和密码) ,然后使用该auth令牌以及客户端的注册ID来执行推送.

编辑2：我在此处对客户端发生的情况的描述是错误的-客户端代码在任何时候均不涉及获取oauth令牌.所有这些东西都由AndroID OS本身处理.本教程：

http://www.vogella.de/articles/AndroidCloudToDeviceMessaging/article.html

很好地展示了C2DM的所有工作原理.

编辑3：我在C2DM上看到的最常见的错误来自文档中对“发件人的电子邮件”的使用.该术语指的是已“注册”用于C2DM的gmail帐户,而不是指AndroID用户的gmail帐户.您的网络服务器应用程序使用此gmail帐户(以及匹配的密码)从C2DM获取oauth令牌. AndroID客户端应用程序需要使用相同的帐户(没有匹配的密码,它不知道),以进行调用,该调用返回一个registrationID,然后将其发送到您的Web服务器.
