我正在开发一个具有Firebase通知的应用，我通过Firebase教程指南来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个从发送设备接收的通知，虽然该设备不应该接受这是从它发送发送了两次Firebase推送通知
我看到关于上传通知其他问题两次通知，但它并没有为我
PS工作：通知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
这里是明显的：
<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这个编译这些：
compile 'com.google.firebase:firebase-core:10.0.0'
compile 'com.google.firebase:firebase-messaging:10.0.0'
这里的自定义对话框代码：
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();
这里是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());
}
这里是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;
?>
我尝试了很多办法，以便找到问题的所在，但我不能知道它是什么
如果需要更多信息，我将重新编辑以添加所需信息
嗨。你可以发布你的'send_push.php'（删除敏感细节）吗？另外，从您的服务器发送消息后，您是否也收到双重响应？ –
你是说如果通知在我的数据库中注册了两次？如果是的话，那么是啊，这是 –
嗨。不。我指的是从你的服务器发送消息，你收到FCM服务器的响应（可能是'200 OK'响应），你是否也收到过两次？ –
