Question

我可以成功存储registration_id。但是当我从我的示例页面发送消息时，我什么都没得到。

我从php得到的回应是。

done{"multicast_id":5441272458021564268,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1454957764463721%e104448af9fd7ecd"}]}

如您所见， canonical_ids 对象的值为零。我认为这应该有一些价值，表明我的消息已发送给GCM。

请检查我的 php代码

<?php
   include("init.php");
   $url = 'https://gcm-http.googleapis.com/gcm/send';
    $apikey = 'AIzaSyDpdrSDJriqAsqCzB7gGURmjrZIm6q0KZM';
   $message="";
$registration_ids = array();
if(isset($_POST['email'])){
    $name = $_POST['email'];
    $message = $_POST['message'];

    $sql = "SELECT * FROM user_info where email = '".$name."'";

    $result = mysqli_query($con,$sql);

    while($row = mysqli_fetch_array($result)){
        array_push($registration_ids,$row['token_id']);

    }
}

$message_send = array("Notice"=>$message);
$fields = array(
    'registration_ids' => $registration_ids,
    'data' => $message_send
);

$headers = array('Authorization: key='.$apikey,
                'Content-Type: application/json'
                );


$ch = curl_init();

curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);

curl_setopt($ch,CURLOPT_POSTFIELDS,json_encode($fields));


$result = curl_exec($ch);
if($result === FALSE){
    die('Curl failed: ' . curl_error($ch));
}

curl_close($ch);
echo "done".$result;

 ?>

我知道推送通知是使用广播接收器和意图服务运行的。

所以

public class MyGcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    ComponentName comp = new ComponentName(context.getPackageName(),GcmIntentService.class.getName());


    startWakefulService(context,(intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);

}

}

和意向服务。

public class GcmIntentService extends IntentService{
public static final int NOTIFICATION_ID = 1;
private static final String TAG="GcmIntentService";
private NotificationManager mNotificationManager;
NotificationCompat.Builder mBuilder;

public GcmIntentService() {
    super("GcmIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);

    String messageType = gcm.getMessageType(intent);

    if(!extras.isEmpty()){
        if(GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)){
            sendNotification("Send error: " + extras.toString());
        }
    }else if(GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)){

        sendNotification("Deleted messages on server: " + extras.toString());

    }else if(GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)){

        sendNotification(extras.getString("Notice"));

        Log.v(TAG,"Received " + extras.toString());
    }

    MyGcmBroadcastReceiver.completeWakefulIntent(intent);
}

private void sendNotification(String s) {
    Log.v(TAG,s);

    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);


    PendingIntent contentIntent = PendingIntent.getActivity(this,0,
            new Intent(this,MainActivity.class),0);


    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                .setContentTitle("GCMDemo")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(s))
                .setContentText(s);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID,mBuilder.build());

}

}

我不确定到底发生了什么。广播接收器是自定义生成和动作并运行IntentService。此服务将消息作为额外的字符串获取。

最后这是我的 manifest.xml 。

<?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="testing.theo.testpushnotifications">

<uses-permission android:name="android.permission.INTERNET" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <receiver android:name=".MyGcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <category android:name="testing.theo.testpushnotifications"/>
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService"/>

    <activity android:name=".Register"></activity>

</application>

感谢。
