在我的FCM中发送通知对象中的徽章

Answer 1

您可以从以下方法检索数据

 @Override
 public void onMessageReceived(RemoteMessage remoteMessage) {

    Map<String, String> data = remoteMessage.getData();
    String title = data.get("title").toString();
    String message = data.get("body").toString();
    String message = data.get("badge").toString();
}

Answer 2

您需要像“ int”一样获得“徽章”

jsonObject.getInt("badge")

Answer 3

按照doc ，您必须以data类型发送通知，以发送/接收自定义参数。 您必须从服务器发送类似

"data":{  
      "title":"[add title]",
      "body":"[add your message]",
      "badge":"11"
   }

在接收方，您可以进行如下分析：

 @Override
        public void onMessageReceived (RemoteMessage remoteMessage){
            super.onMessageReceived(remoteMessage);
            Log.d(TAG, "From: " + remoteMessage.getFrom());
            // Check if message contains a data payload.
            if (remoteMessage.getData().size() > 0) {
                Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());

                try {
                    Map<String, String> map = remoteMessage.getData();

                    handleDataMessage(map);

                } catch (Exception e) {
                    Log.e(TAG, "Exception: " + e.getMessage());
                }
            }

        }

        private void handleDataMessage(Map<String,String> json){
            Log.e(TAG, "push json: " + json.toString());

            try {

                String title = json.get("title");
                String message = json.get("body");
                String badge = json.get("badge");

              // Display notication depends on received data


            } catch (Exception e) {
                Log.e(TAG, "Exception: " + e.getMessage());
            }
        }
