使用GCM，沒有錯誤，但沒有收到消息

我正在嘗試使用GCM。我想從服務器（PHP文件）發送消息到我的設備（Android手機）使用GCM，沒有錯誤，但沒有收到消息

這個想法是啓動應用程序，加載任何導航器上的test.php（鉻，火狐......），然後應在我的手機上顯示通知。其實，我的手機沒有任何事情發生。在Android Studio的日誌中，我可以看到GCM註冊令牌，所以對此可以。但之後......我有點失落。我如何檢查發送到服務器的消息？我如何知道該服務正在收聽應用程序？

這裏是我的實際文件，我沒有錯誤，當我發送消息時，我開始應用：

test.php的

<?php 

ini_set('display_errors', 1); 
ini_set('display_startup_errors', 1); 
error_reporting(E_ALL); 

require_once __DIR__ . '/gcm.php'; 

$gcm = new GCM(); 

$data = array(); 
$data['message'] = "Un message de test"; 

// the topic you want to send notification 
$topic = 'global'; 

// sending push message to a topic 
$gcm->sendToTopic($topic, $data); 

?>

gcm.php（我已刪除從API密鑰這裏）

<?php 
class GCM { 

    // constructor 
    function __construct() { 

    } 

    // sending push message to single user by gcm registration id 
    public function send($to, $message) { 
     $fields = array(
      'to' => $to, 
      'data' => $message, 
     ); 
     return $this->sendPushNotification($fields); 
    } 

    // Sending message to a topic by topic id 
    public function sendToTopic($to, $message) { 
     $fields = array(
      'to' => '/topics/' . $to, 
      'data' => $message, 
     ); 
     return $this->sendPushNotification($fields); 
    } 

    // sending push message to multiple users by gcm registration ids 
    public function sendMultiple($registration_ids, $message) { 
     $fields = array(
      'registration_ids' => $registration_ids, 
      'data' => $message, 
     ); 

     return $this->sendPushNotification($fields); 
    } 

    // function makes curl request to gcm servers 
    private function sendPushNotification($fields) { 

     // include config 

     // Set POST variables 
     $url = 'https://gcm-http.googleapis.com/gcm/send'; 

     $headers = array(
      'Authorization: key=AIz...', 
      'Content-Type: application/json' 
     ); 
     // Open connection 
     $ch = curl_init(); 

    // Set the url, number of POST vars, POST data 
    curl_setopt($ch, CURLOPT_URL, $url); 

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

    // Disabling SSL Certificate support temporarly 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 

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

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

    // Close connection 
    curl_close($ch); 

    return $result; 
}}?>

而對於應用程序：

MainActivity.java

protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     // Registering BroadcastReceiver 
     //registerReceiver(); 

     if (checkPlayServices()) { 
      // Start IntentService to register this application with GCM. 
      Intent intent = new Intent(this, RegistrationIntentService.class); 
      startService(intent); 

     } 
... 
private boolean checkPlayServices() { 
     GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance(); 
     int resultCode = apiAvailability.isGooglePlayServicesAvailable(this); 
     if (resultCode != ConnectionResult.SUCCESS) { 
      if (apiAvailability.isUserResolvableError(resultCode)) { 
       apiAvailability.getErrorDialog(this, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST) 
         .show(); 
      } else { 
       Log.i(TAG, "This device is not supported."); 
       finish(); 
      } 
      return false; 
     } 
     return true; 
    }

RegistrationIntentService.java

public class RegistrationIntentService extends IntentService { 

    private static final String TAG = "RegIntentService"; 
    private static final String[] TOPICS = {"global"}; 

    public RegistrationIntentService() { 
     super(TAG); 
    } 

    @Override 
    protected void onHandleIntent(Intent intent) { 
     SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this); 

     try { 
      InstanceID instanceID = InstanceID.getInstance(this); 
      String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId), 
        GoogleCloudMessaging.INSTANCE_ID_SCOPE, null); 
      Log.i(TAG, "GCM Registration Token: " + token); 


      sendRegistrationToServer(token); 

      subscribeTopics(token); 
     sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, true).apply(); 

     } catch (Exception e) { 
      Log.d(TAG, "Failed to complete token refresh", e); 

      sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false).apply(); 
     } 
    } 

    /**

    private void sendRegistrationToServer(String token) { 
     // Add custom implementation, as needed. 
    } 

    /**

    */ 
    // [START subscribe_topics] 
    private void subscribeTopics(String token) throws IOException { 
     GcmPubSub pubSub = GcmPubSub.getInstance(this); 
     for (String topic : TOPICS) { 
      pubSub.subscribe(token, "/topics/" + topic, null); 
     } 
    } 
    // [END subscribe_topics] 

}
