firebaseクラウドメッセージングを使用してmysqlデータベースにトークンを登録できません

Question

私はこれまでのところ、Firebase Cloud Messaging Apiでプッシュ通知を行いました。データベースは、チュートリアルに従っていて、トークンは登録されていないようです。

MainActivity.java http://prntscr.com/bgadg6

MyFirebaseInstanceIDService.java http://prntscr.com/bgadxd

MyFirebaseMessagingService延びFirebaseメッセージングサービス{

private static final String TAG = "MyFirebaseMsgService"; 

@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
    //Displaying data in log 
    //It is optional 
    Log.d(TAG, "From: " + remoteMessage.getFrom()); 
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 

    //Calling method to generate notification 
    sendNotification(remoteMessage.getNotification().getBody()); 
} 

//This method is only generating push notification 
//It is same as we did in earlier posts 
private void sendNotification(String messageBody) { 
    Intent intent = new Intent(this, MainActivity.class); 
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 
      PendingIntent.FLAG_ONE_SHOT); 

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
      .setSmallIcon(R.mipmap.ic_launcher) 
      .setContentTitle("Firebase Push Notification") 
      .setContentText(messageBody) 
      .setAutoCancel(true) 
      .setSound(defaultSoundUri) 
      .setContentIntent(pendingIntent); 

    NotificationManager notificationManager = 
      (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

    notificationManager.notify(0, notificationBuilder.build()); 
} 

}

AndroidManifest.xmlを

ボレーライブラリ& asyntaskで、これを試してみてください：

//Creating a string request 
     StringRequest req = new StringRequest(Request.Method.POST, Constants.REGISTER_URL, 
       new Response.Listener<String>() { 
        @Override 
        public void onResponse(String response) { 
         //dismissing the progress dialog 
         progressDialog.dismiss(); 

         //if the server returned the string success 
         if (response.trim().equalsIgnoreCase("success")) { 
          //Displaying a success toast 
          Toast.makeText(MainActivity.this, "Registered successfully", Toast.LENGTH_SHORT).show(); 


         } else { 
          Toast.makeText(MainActivity.this, "Choose a different email", Toast.LENGTH_SHORT).show(); 
         } 
        } 
       }, 
       new Response.ErrorListener() { 
        @Override 
        public void onErrorResponse(VolleyError error) { 

        } 
       }) { 
      @Override 
      protected Map<String, String> getParams() throws AuthFailureError { 
       Map<String, String> params = new HashMap<>(); 
       //adding parameters to post request as we need to send firebase id and email 
       params.put("firebaseid", uniqueId); 
       params.put("email", email); 
       return params; 
      } 

とregister.php

<?php 

if($_SERVER['REQUEST_METHOD']=='POST'){ 

    //getting the request values 
    $firebaseid = $_POST['firebaseid']; 
    $email = $_POST['email']; 

    //connecting to database 
    $con = mysqli_connect('localhost','root','','pushnotification'); 

    //creating an sql query 
    $sql = "INSERT INTO register (firebaseid, email) VALUES ('$firebaseid','$email')"; 

    //executing the query to the database 
    if(mysqli_query($con,$sql)){ 
     echo 'success'; 
    }else{ 
     echo 'failure'; 
    } 
}
