如何解决c2dm：如何在设备中接收消息？ 使用PHP
| 我有c2dm的注册ID和身份验证令牌。然后我将这些值存储在db中。并使用PHP，我可以向c2dm服务器发送一条消息。但是我的问题是我不知道如何在应用程序中接收消息。我不确定我收到消息的方式是否正确。无论如何，我将在下面给出。 我有一个使用注册意图向c2dm注册的活动。一个接收器，接收reg_id和通知消息。它正在向c2dm注册并且不接收消息。 表现 <intent-filter>
<action android:name=\"com.google.android.c2dm.intent.REGISTRATION\"></action>
<category android:name=\"my.android.c2dm\"></category>
</intent-filter>
<intent-filter>
<action android:name=\"com.google.android.c2dm.intent.RECEIVE\"></action>
<category android:name=\"my.android.c2dm\"></category>
</intent-filter>
</receiver>
</application>
Intent objRegIntnet=new Intent(\"com.google.android.c2dm.intent.REGISTER\");
objRegIntnet.putExtra(\"app\",PendingIntent.getbroadcast(this,new Intent(),0));
objRegIntnet.putExtra(\"sender\",\"mymail@gmail.com\");
startService(objRegIntnet);
public class c2dmReceiver extends broadcastReceiver
{
private static String KEY = \"c2dmPref\";
private static String REGISTRATION_KEY = \"registrationKey\";
private Context context;
@Override
public void onReceive(Context context,Intent intent)
{
this.context = context;
if (intent.getAction().equals(\"com.google.android.c2dm.intent.REGISTRATION\"))
{
handleRegistration(context,intent);
}
else if (intent.getAction().equals(\"com.google.android.c2dm.intent.RECEIVE\"))
{
handleMessage(context,intent);
}
}
private void handleRegistration(Context context,Intent intent)
{
//handles registeration
}
private void handleMessage(Context context,Intent intent)
{
String title= intent.getStringExtra(\"title\");
String message= intent.getStringExtra(\"msg\");
Toast.makeText(context,\"title : \"+title+\"\\n message : \"+message,1).show();
//Do whatever you want with the message
}
function sendMessagetoPhone($authCode,$deviceRegistrationId,$msgType,$messageText)
{
//$messageText=\"have a nice day\";
//$msgtype=\"important\";
$headers = array(\'Authorization: GoogleLogin auth=\' . $authCode);
$data = array(
\'registration_id\' => $deviceRegistrationId,\'collapse_key\' => $msgType,\'data.message\' => $messageText
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,\"https://android.apis.google.com/c2dm/send\");
if ($headers)
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,CURLOPT_POSTFIELDS,$data);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
解决方法
最终，我找到了提供crash_key和and数据的方法。
crash_key应该是一个字符串，它是一组消息的名称或特定类型的消息。如果我们使用相同的crash_key发送多个消息，则最新消息将从c2dm服务器发送到设备。
例如：$ collapse_key = \“ important \”;
和数据。是重要的这将包含我们要发送的消息。
例如：如果我们要发送消息“祝您有愉快的一天”，那么我应该给它起一个关键的名字。
数据。= \“祝您有美好的一天\”；
这里的“愿望”是关键。在接收器中，我应该检索具有相同键名的消息。

String mywish= intent.getStringExtra(\"wishes\");
