更新

已解决 - 感谢@MusiGenesis 的坚持,我通过注册一个新的 Google 邮件帐户和一个新的 C2DM 帐户解决了这个问题。在网络服务器和 Android 应用程序中更新相关凭据后,所有这些都开始像魔术一样工作。

更新结束

我正在寻找发送推送通知时 401 未经授权错误原因的明确列表,以便我可以尝试消除我的问题。

我有一个用 C2DM 注册的谷歌邮箱我可以使用 curl 获取授权码

我的 android 应用程序上有注册用户的授权 token

使用 2 个身份验证 token (已刷新),当从我的网络服务器发送推送通知请求时,我从我的网络服务器收到 401 未经授权的错误。

据我所知,我正在做我需要做的一切,所以我正在寻找我可能遗漏的东西。我已经搜索了互联网,很多人似乎都遇到了同样的问题,但没有明确的答案。非常感谢任何帮助

更新

正如下面的答案中提到的,似乎需要第二个阶段才能获得注册 ID,该 ID 似乎与注册用户在 Android 应用程序上收到的授权 token 不同。看了jumpnote代码和这两个资源

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

http://marakana.com/forums/android/general/272.html

除了授权 token 之外,我没有看到有关获取注册 ID 的第二次注册调用的信息。我显然遗漏了一些东西,如果有人能为我解释清楚,我将不胜感激。

** 更新 2 **

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 onError(Context context, String errorId) {
Log.e("C2DM", "Error occured!!!");
}
}

从 jumpnote 应用程序中获取的 C2DMBaseReceiver 看起来像这样

/**
* Base class for C2D message receiver. Includes constants for the
* strings used in the protocol.

public abstract class C2DMBaseReceiver extends IntentService {

最佳答案

您说您“拥有来 self 的 Android 应用程序注册用户的授权 token ”。您可能刚刚写错了,但如果您的意思是您使用的是注册用户的 auth token 而不是用户从 C2DM 服务器返回的 registration id ,那么你的问题就在那里。

编辑:您的客户端应用程序(在设备上运行)使用 C2DM 的 3 步过程:1) 调用 C2DM 服务器传递客户端的 gmail 帐户 ID 和密码,取回身份验证 token ; 2) 使用步骤 1 中的 auth token 再次调用 C2DM 服务器,取回注册 ID(96-120 个字符的 ASCII spooge); 3) 调用您的服务器应用程序并传递在第 2 步中获得的注册 ID(而不是在第 1 步中获得的auth token)。

当您的服务器应用程序想要向客户端推送内容时,它会调用 C2DM 服务器以获取身份验证 token (传递您用于注册 C2DM 服务器的电子邮件和密码,不是 客户端用户的电子邮件和密码),然后使用该身份验证 token 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都不涉及获取 oauth token 。所有这些东西都由 Android 操作系统本身处理。本教程:

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

很好地展示了 C2DM 的一切运作方式。

编辑 3:我见过的 C2DM 最常见的错误是文档中使用了短语“发件人的电子邮件”。该术语是指“注册”用于 C2DM 的 gmail 帐户,而不是指 Android 用户的 gmail 帐户。您的 Web 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 token 。 Android 客户端应用程序需要使用相同的帐户(没有匹配的密码,它不知道该密码)进行调用以返回一个 registrationId,然后将其发送到您的网络服务器。
