Question

我已经为我的Android应用创建了推送通知，当我尝试从firebase控制台发送它时，它的工作正常。现在我想要的是当用户点击注册然后显示其他用户的通知时发出推送通知。

我在谷歌搜索但没有找到其中一个例子。目标是告诉其他用户我的应用程序中有新用户注册。

感谢您的帮助

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMessagingService";
    public static final int ID_SMALL_NOTIFICATION = 235;
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // ...

        // TODO(developer): Handle FCM messages here.

        Log.d(TAG, "From: " + remoteMessage.getFrom());

        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0) {
            Log.d(TAG, "Message data payload: " + remoteMessage.getData());
            sendNotification("Hi ini isinya");
        }

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
            Log.d(TAG,"Message Notification Title" + remoteMessage.getNotification().getTitle());
            Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
        }

        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated. See sendNotification method below.
    }

    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, ID_SMALL_NOTIFICATION, intent,
                PendingIntent.FLAG_ONE_SHOT);

        String channelId = "fcm_default_channel";
        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.drawable.icon)
                        .setContentTitle("FCM Message")
                        .setContentText(messageBody)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setContentIntent(pendingIntent);

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

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

}

我没有明白你的意思，但你可以使用Volly Json对象请求

首先，您需要从Firebase控制台复制服务器密钥，打开Firebase Console并选择您的项目

第二个在项目中添加Volley依赖

编译'com.mcxiaoke.volley：library：1.0.19'

然后你可以添加这个代码来推送

private void sendFCMPush() {

            String SERVER_KEY = YOUR_SERVER_KEY;
            String msg = "this is test message";
            String title = "my title";
            String token = FCM_TOKEN;

            JSONObject obj = null;
        JSONObject objData = null;
        JSONObject dataobjData = null;

        try {
            obj = new JSONObject();
            objData = new JSONObject();

            objData.put("body", msg);
            objData.put("title", title);
            objData.put("sound", "default");
            objData.put("icon", "icon_name"); //   icon_name
            objData.put("tag", token);
            objData.put("priority", "high");

            dataobjData = new JSONObject();
            dataobjData.put("text", msg);
            dataobjData.put("title", title);

            obj.put("to", token);
            //obj.put("priority", "high");

            obj.put("notification", objData);
            obj.put("data", dataobjData);
            Log.e("return here>>", obj.toString());
        } catch (JSONException e) {
            e.printStackTrace();
        }

            JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST, Constants.FCM_PUSH_URL, obj,
                    new Response.Listener<JSONObject>() {
                        @Override
                        public void onResponse(JSONObject response) {
                            Log.e("True", response + "");
                        }
                    },
                    new Response.ErrorListener() {
                        @Override
                        public void onErrorResponse(VolleyError error) {
                            Log.e("False", error + "");
                        }
                    }) {
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    Map<String, String> params = new HashMap<String, String>();
                    params.put("Authorization", "key=" + SERVER_KEY);
                    params.put("Content-Type", "application/json");
                    return params;
                }
            };
            RequestQueue requestQueue = Volley.newRequestQueue(this);
            int socketTimeout = 1000 * 60;// 60 seconds
            RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
            jsObjRequest.setRetryPolicy(policy);
            requestQueue.add(jsObjRequest);
}

希望这个帮助

当一个用户点击注册给已经注册的其他人时，你想发送推送，对吧？您需要向此地址发出HTTP POST请求：

https://fcm.googleapis.com/fcm/send

标题为＆＃34;授权＆＃34;像这样的价值＆＃34; key = AIza ......＆＃34;。

因此，在请求正文中，您可以发送类似这样的JSON。

{
  "to": "/topics/foo-bar",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!",
   }
}

然后您需要创建一个主题并将设备订阅到同一主题。

FirebaseMessaging.getInstance().subscribeToTopic("foo-bar");

这应该可以正常工作。
