C2DM 推送通知 导致 401 未授权错误的原因是什么?

更新

已解决 - 感谢@MusiGenesis 的坚持,我通过注册新的 Google 邮件帐户和新的 C2DM 帐户解决了问题。更新网络服务器中的相关凭据后,Android 应用程序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出现 401 未经授权错误的原因的明确列表,以便我可以尝试消除我的问题。

我有一个在 C2DM 上注册的 google 电子邮件 我可以使用curl来获取授权码

我从我的android应用程序上的注册用户那里获得了身份验证令牌

使用2个身份验证令牌(刷新)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缺少的东西。我在网上查了一下,似乎很多人都有同样的问题,但没有明确的答案。 任何帮助都非常感谢

更新

正如下面的答案中提到的,似乎需要第二阶段来获取注册ID,该ID似乎与Android应用程序上注册用户收到的身份验证令牌不同。查看了 Jumpnote 代码和这两个资源

我明白了没有关于第二次注册调用以获取除身份验证令牌之外的注册 ID 的信息。我显然错过了一些东西,如果有人能为我拼写出来,我将不胜感激。

我的 C2DM 接收器看起来像

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

UPDATE

SOLVED - Thank's to @MusiGenesis persistence with this I solved the problem by registering a new Google mail account and a new C2DM account. After updating the relevant credentials in the web server and the android app all started working like magic.

END OF UPDATE

I'm looking for a definitive list for causes of 401 unauthorised errors when sending a push notification so I can try to eliminate my problem.

I have a google email registered with C2DM
I can use curl to get an authorisation code

I have the auth token from the registered user on my android app

Using the 2 auth tokens (refreshed) I get 401 unauthorised errors from my web server when sending a push notification request from my web server.

As far as I can tell I am doing everything I need to do so I'm looking for what I may be missing. I have scoured the internet and lots of people seem to be having the same problem with no definite answer.
Any help greatly appreciated

UPDATE

As mentioned in the answer below it seems there is a second stage required to get a registration ID which appears to be different from the auth token received by the registered user on the android app. Having looked at the jumpnote code and these two resources

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

and

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

I see no info regarding a second registration call to get a regisration ID in addition to the auth token. I'm obviously missing something and would be gratefull if someone could spell this out for me.

** UPDATE 2 **

My C2DM Receiver looks like this

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!!!");
    }
}

你说你“拥有我的 Android 应用程序上注册用户的身份验证令牌”。您可能刚刚写错了,但如果您的字面意思是您正在使用注册用户的身份验证令牌,而不是用户从 C2DM 服务器返回的注册 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 步流程:1) 调用 C2DM 服务器传递客户端的 Gmail 帐户 ID 和密码,获取身份验证令牌; 2) 使用步骤 1 中的身份验证令牌再次调用 C2DM 服务器,获取注册 ID(这是 ASCII splooge 的 96-120 个字符); 3) 调用您的服务器应用程序并传递在步骤 2 中获取的注册 ID(而不是在步骤 1 中获取的身份验证令牌)。

当您的服务器应用程序想要将某些内容推送到客户端时,它会调用 C2DM 服务器以获取身份验证令牌(传递您用于注册 C2DM 服务器的电子邮件和密码,而不客户端用户的电子邮件和密码),然后使用该身份验证令牌以及客户端的注册 ID 来执行推送。

编辑2:我在这里对客户端上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令牌。所有这些事情都是由 Android 操作系统本身处理的。本教程:

http://www.vogella.de/articles/AndroidCloudToDeviceMessaging/article.html< /a>

很好地展示了 C2DM 的一切工作原理。

编辑 3: 我在 C2DM 中看到的最常见错误来自于文档中使用短语“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 令牌。 Android 客户端应用程序需要使用同一个帐户(没有匹配的密码,它不知道该密码)来进行调用,以返回注册 ID,然后将其发送到您的 Web 服务器。

You say you "have the auth token from the registered user on my android app". You may have just written that incorrectly, but if you mean literally that you're using the registered user's auth token and not the registration id the user got back from the C2DM server, then there's your problem right there.

Edit: Your client app (running on the device) uses a 3-step process for C2DM: 1) call the C2DM server passing the client's gmail account id and password, get back an auth token; 2) call the C2DM server again using the auth token from step 1, get back a registration id (which is 96-120 characters of ASCII splooge); 3) call your server app and pass the registration id obtained in step 2 (not the auth token obtained in step 1).

When your server app then wants to push something to the client, it makes a call to the C2DM server to get an auth token (passing the email and password you used to sign up for the C2DM server, not the client user's email and password), then uses that auth token along with the client's registration id to execute the push.

Edit 2: my description here of what happens on the client is wrong - the client code does not involve getting an oauth token at any point. All of that stuff is handled by the Android OS itself. This tutorial:

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

shows nicely how everything works for C2DM.

Edit 3: The most common mistake I've seen with C2DM comes from the documentation's use of the phrase "sender's email". This term refers to the gmail account that was "registered" for use with C2DM, and does not refer to the gmail account of the Android user. This gmail account is used by your web server app (along with the matching password) to get an oauth token from C2DM. This same account needs to be used by the Android client app (without the matching password, which it doesn't know) to make the call that gets back a registrationId that it then sends to your web server.
