从 FCM onMessageReceived 方法的 RemoteMessage 获取值

Question

我已迁移 gcm to fcm 推送通知消息。但是我如何从 RemoteMessage 获取捆绑数据收到 onMesssageReceived 方法。

Old GCM give bundle data onMessageReceiced method but in FCM there is RemoteMessage data.

所以请告诉我如何解析远程消息以获取通知的所有值。

  },

Answer 1

这里是代码片段，几乎可以自我解释。

你得到的是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 "data" 键

这里是演示Json文件

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

Answer 2

在 FCM 中，您收到的是 RemoteMessage 而不是 Bundle。

下面是我在我的应用程序中使用的方式，其中数据是我的 RemoteMessage

Map<String, String> data = remoteMessage.getData()
int questionId = Integer.parseInt(data.get("questionId").toString());
String questionTitle = data.get("questionTitle").toString();
String userDisplayName = data.get("userDisplayName").toString();
String commentText = data.get("latestComment").toString();

以下是我从服务器发送的通知数据

{
  "registration_ids": "",
  "data": {
    "questionId": 1,
    "userDisplayName": "Test",
    "questionTitle": "Test",
    "latestComment": "Test"
  }
}

因此您必须根据您的回复解析每个字段。当我调试代码时，您将在 RemoteMessage 中收到映射并将这些字段转换为适当的数据类型，因为所有这些数据都以字符串形式出现。

您的数据如下：

"data":{ 
    "message": "Message for new task",
    "time": "6/27/2016 5:24:28 PM"
}

你应该让他们通过

Log.d(TAG, "Key Data : " +  remoteMessage.getData().get("message").toString());
Log.d(TAG, "Key Data : " +  remoteMessage.getData().get("time").toString());

将它们包裹在 try catch 中以确保

Answer 4

RemoteMessage.Notification notification = remoteMessage.getNotification();
        Map<String, String> data = remoteMessage.getData();
        sendNotification(notification, data);
String urlparam=data.get("url_param").toString();
String urlparam=data.get("dp_name").toString();

"data": {
    "notification_id": 11,
    "title_url": "service_id=1;service_category=Installation;",
    "destination": "Category_page"
  }

Answer 5

getData() 的乐趣类型是 Map<String, String>。所以你可以像我们通常使用 Map<String, String>.

那样获取 data 对象值

"data": {
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
    "key4": "value4"
  }

然后你必须在 kotlin 中像这样获取

val data = remoteMessage.data
val key1 = data[key1]
val key2  = data[key2]// you can fetch like this

对于getNotification()类型是Notification对象

val notification: Notification =  remoteMessage.notification
val message = notification.body
val title = notification.title // you can fetch by accessing Notification class member
