android - FCM onReceivedMessage() 获取 Bundle

Question

link of structure

我正在尝试从我的 ArrayMap 获取消息，但我无法访问 ReceiveMessage 包。我尝试直接访问Map，但是非常错误

我的代码

public class FbService extends FirebaseMessagingService {
    public FbService() {
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO(developer): Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // 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.

        Map<String, String> params = remoteMessage.getData();
        String message =  params.get(3);

        Log.d("FbService", "Notification Message Body: " + message);



    }
}

感谢@Pritish Joshi

我找到了这个答案，对我帮助很大, 这是代码 fragment

获取Map形式的数据

public void onMessageReceived(RemoteMessage remoteMessage)
        {
            Log.e("dataChat",remoteMessage.getData().toString());
            try
            {
                Map<String, String> params = remoteMessage.getData();
                JSONObject object = new JSONObject(params);
                Log.e("JSON_OBJECT", object.toString());
          }
       }

确保从服务器发送的数据格式正确，即在“数据”键中

这是演示 Json 文件

{
  "to": "registration_ids",
  "data": {
    "key": "value",
    "key": "value",
    "key": "value",
    "key": "value"
  }
}
