android - Firebase 推送通知发送两次

Question

我正在开发一个具有 firebase 通知的应用程序，我按照 firebase 教程指南了解如何发送和接收通知，但我在其他设备上收到 2 个通知，而不是收到 1 个通知并从发送的设备接收通知尽管该设备不应该收到从它发送的通知

我看到了有关两次上传通知的其他问题，但它对我不起作用

P.S:通知是从具有标题编辑文本和正文编辑文本的自定义对话框发送的

这是 list :

<service
        android:name=".MyFirebaseInstanceIDService"
        android:exported="false">
        <intent-filter>
            <action
                android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>

<service
        android:name=".MyFirebaseMessagingService"
        android:exported="false">
        <intent-filter>
            <action
                android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

我在gradle中编译这些:

compile 'com.google.firebase:firebase-core:10.0.0'
compile 'com.google.firebase:firebase-messaging:10.0.0'

这是自定义对话框的代码:

builder = new AlertDialog.Builder(this);
        final View view = View.inflate(this, R.layout.layout_send_notification, null);
        builder.setView(view)
                .setCancelable(true)
                .setPositiveButton(getString(R.string.send), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        EditText editMessage = (EditText) view.findViewById(R.id.notification_message);
                        EditText editTitle = (EditText) view.findViewById(R.id.notification_title);
                        Calendar now = Calendar.getInstance();
                        int day = now.get(Calendar.DAY_OF_MONTH);
                        int month = now.get(Calendar.MONTH) + 1;
                        int year = now.get(Calendar.YEAR);
                        String message = editMessage.getText().toString().replace(' ', '_');
                        String title = editTitle.getText().toString().replace(' ', '_');

                        boolean cancel = false;
                        View focusView = null;

                        if (TextUtils.isEmpty(message)) {
                            editMessage.setError(getString(R.string.error_field_required));
                            focusView = editMessage;
                            cancel = true;
                        }

                        if (TextUtils.isEmpty(title)) {
                            editTitle.setError(getString(R.string.error_field_required));
                            focusView = editTitle;
                            cancel = true;
                        }

                        if (cancel)
                            focusView.requestFocus();
                        else {
                            RequestQueue queue = Volley.newRequestQueue(NotificationsActivity.this);
                            String url = "https://mysite.here/send_push.php?" +
                                    "message=" + message +
                                    "&title=" + title +
                                    "&day=" + day +
                                    "&month=" + month +
                                    "&year=" + year;
                            StringRequest request = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
                                @Override
                                public void onResponse(String response) {
                                    Log.d("send push response", response);
                                }
                            }, new Response.ErrorListener() {
                                @Override
                                public void onErrorResponse(VolleyError error) {
                                    error.printStackTrace();
                                }
                            });
                            queue.add(request);
                        }
                    }
                })
                .setNegativeButton(getString(R.string.button_cancel), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        dialogInterface.cancel();
                    }
                });
        sendNotificationDialog = builder.create();

这是firebaseMessagingService:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}

private void sendNotification(String messageTitle, String messageBody) {
    Intent intent = new Intent(this, SplashActivity.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)
            .setContentTitle(messageTitle)
            .setContentText(messageBody)
            .setSmallIcon(R.drawable.ic_stat_spe_bau)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

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

这是 firebaseInstanceIDService:

@Override
public void onTokenRefresh() {
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d("firebase ID", refreshedToken);
    sendRegistrationToServer(refreshedToken);
}

private void sendRegistrationToServer(String token) {
    RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
    String url = "https://mysite.here/insertFCM_ID.php?fcmID=" + token;
    StringRequest request = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.d("fcm response", response);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
        }
    });
    queue.add(request);
}

send_push.php 代码:

<?php
header("Content-type: application/json, charset=UTF-8");
require('db.php');

$db = mysqli_connect($host, $username, $password) or die('Could not connect');
mysqli_select_db($db, $db_name) or die('');
$message    = $_GET['message'];
$title      = $_GET['title'];
$day        = $_GET['day'];
$month      = $_GET['month'];
$year       = $_GET['year'];

$server_key = "somekey";
$sql        = 'select fcm_token from fcm_info';
$result     = mysqli_query($db, $sql) or print("Error");
$key        = array();

while ($row = mysqli_fetch_assoc($result)) {
    $key[] = $row;
}

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

foreach($key as $value) {
    $single  = $value['fcm_token'];

    $fields  = array(
        'to' => $single,
        'notification' => array(
            'title' => str_replace("_", " ", $title),
            'body' => str_replace("_", " ", $message),
            'vibrate' => 1,
            'sound' => 1
        )
    );
    $payload = json_encode($fields);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
    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_IPRESOLVE, CURL_IPRESOLVE_V4);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
    $result = curl_exec($ch);
}

mysqli_query($db, "INSERT INTO notifications (title, body, day, month, year) VALUES ('$title', '$message', '$day', '$month', '$year')");

mysqli_close($db);
echo $result;
?>

我尝试了很多方法来找出问题所在，但我不知道它是什么

如果需要更多信息，我将重新编辑以添加所需信息

Answer 1

在您的 onMessageReceived 事件中添加注释行:

//sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}

在您的 firebaseInstanceIDService 类中进行此更改后重试。应该没问题。
如果您只想使用下游消息，则需要确定您的消息类型。数据消息或通知。您还需要管理您的应用在设备上的 3 种情况:前台、后台和已终止。数据消息总是在您的服务上触发 onMessageReceived 事件。这在您发送通知消息时有所不同。我建议您将数据消息作为 Post 请求发送。你现在没有任何问题。您正在向“ https://fcm.googleapis.com/fcm/send”发送 Post 请求' 通过 Volley 的 URL，您正在发送通知。然后您的服务正在接收您的通知并创建另一个。收到 2 个通知是很正常的，因为您的代码正在生成 2 个通知。我告诉你做评论行并测试它。
