java - 无法使用firebase云消息传递在mysql数据库中注册 token

Question

我正在使用推送通知进行一些工作，到目前为止我已经成功地使用了它，并且使用 Firebase Cloud Messaging Api，现在我试图将 token 保存在数据库中，正在遵循教程，但 token 似乎没有注册。

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

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

MyFirebaseMessagingService 扩展了 Firebase Messaging Service{

  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());
}

}

使用 volley 库和异步任务试试这个:

//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;
            }

和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';
    }
}
