Firebase云消息传递，接收通知中的问题

标签： php google-cloud-messaging android-notifications firebase-cloud-messaging

我正在尝试编写一个应用程序，以通过Firebase云消息接收通知。当我尝试通过Firebase控制台发送消息时它最初工作但是当我尝试使用php webservice做同样的事情时，作为回应，它显示成功但我既没有收到消息也没有我能通过firebase控制台获得更多通知。请帮忙

我的服务器端代码：

MainActivity.java 

package com.example.mojojojo.firebasenotifications;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.EditText;

import com.google.firebase.iid.FirebaseInstanceId;

public class MainActivity extends AppCompatActivity {

    private EditText etToken;
    private SharedPreferences sp;
    private SharedPreferences.Editor edit;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        etToken=(EditText)findViewById(R.id.etToken);

        sp=getSharedPreferences("pref",MODE_PRIVATE);
        edit=sp.edit();

        etToken.setText(FirebaseInstanceId.getInstance().getToken());
        BroadcastReceiver tokenReceiver=new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String token=intent.getExtras().getString("token");
                if(token!=null){
                    etToken.setText(token);
                }
            }
        };
        registerReceiver(tokenReceiver,new IntentFilter("TOKEN_GENERATED"));
    }
}

消息传递服务 

package com.example.mojojojo.firebasenotifications;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        String msg=remoteMessage.getNotification().getBody();
        sendNotification(msg);
        Log.i("/>/>",msg);
    }
    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("FCM Message")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

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

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

令牌服务 

package com.example.mojojojo.firebasenotifications;

import android.app.Service;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.IBinder;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class TokenService extends FirebaseInstanceIdService {
    private SharedPreferences sp;
    private SharedPreferences.Editor edit;

    @Override
    public void onTokenRefresh() {
        super.onTokenRefresh();

        sp=getSharedPreferences("pref",MODE_PRIVATE);
        edit=sp.edit();

        String token= FirebaseInstanceId.getInstance().getToken();
        edit.putString("token",token);

        Intent tokenIntent=new Intent("TOKEN_GENERATED");
        tokenIntent.putExtra("token",token);
        sendBroadcast(tokenIntent);
    }
}

这个PHP代码终于为我工作了。

<?php 
function send_notification ($tokens)
{

    $url = 'https://fcm.googleapis.com/fcm/send';
    $priority="high";
    $notification= array('title' => 'Some title','body' => 'hi' );

    $fields = array(
         'registration_ids' => $tokens,
         'notification' => $notification

        );


    $headers = array(
        'Authorization:key=xxxxxxxxxxxxx',
        '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 ($ch, CURLOPT_SSL_VERIFYHOST, 0);  
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
   curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
    // echo json_encode($fields);
   $result = curl_exec($ch);           
   echo curl_error($ch);
   if ($result === FALSE) {
       die('Curl failed: ' . curl_error($ch));
   }
   curl_close($ch);
   return $result;
}
$tokens = array('RECEIVER-TOKEN-1'
    ,'RECEIVER_TOKEN-2');

  $message_status = send_notification($tokens);
  echo $message_status;
?>

P.S：我现在已经硬编码了接收器令牌（用于测试目的）

答案 1 :(得分：1)

在echo $result之后，您尚未发布结果消息。因此，在查看完代码后，我发现：

  

String msg=remoteMessage.getNotification().getBody();

此行导致问题。您应该像这样使用它：

remoteMessage.getData().get("message")
remoteMessage.getData().get("title")
remoteMessage.getData().get("subtitle")

依旧......

为了进一步清除，我们使用：

当我们发送到fcm服务器的JSON中有remoteMessage.getNotification().getBody()个对象时，

notification。在你的情况下不存在，而是你有data个对象，为此我们使用：

remoteMessage.getData().get("key_name")

试试这个：

<?php 

function send_notification ($tokens, $message)
{
    $url = 'https://fcm.googleapis.com/fcm/send';
    $fields = array(
         'registration_ids' => $tokens,
         'data' => $message
        );

    $headers = array(
        'Authorization:key = YOUR_KEY ',
        '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 ($ch, CURLOPT_SSL_VERIFYHOST, 0);  
   curl_setopt($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);
   return $result;
}


$conn = mysqli_connect("localhost","root","","fcm");

$sql = " Select Token From users";

$result = mysqli_query($conn,$sql);
$tokens = array();

if(mysqli_num_rows($result) > 0 ){

    while ($row = mysqli_fetch_assoc($result)) {
        $tokens[] = $row["Token"];
    }
}

mysqli_close($conn);

   $message = array("message" => " FCM PUSH NOTIFICATION TEST MESSAGE");
   $message_status = send_notification($tokens, $message);
   echo $message_status;

?>

这对我有用...... FCM端点可能不那么可靠。试试这个

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

这不要改变别的。此端点也将继续存在，谷歌没有计划弃用GCM，如其开发者视频中所述。

还有一件事......是否有延迟或者你根本没有得到消息。如果有延迟可能是由于TCP超时问题。试试这个让我知道。祝你好运!!
