获取JSON值从remoteMessage Received onmessagerreceived方法[FCM]推送通知

Question

如何在json对象data中获得json对象payload的值image_id，我从onMessageReceived方法中包含的remoteMessage获得?

MyFirebaseMessagingService.java

public class MyFirebaseMessagingService extends FirebaseMessagingService {

这是我要解析的json。

{ "data": {
"judul_push":"jdl",
"pesan_push":"Isi",
"image_push": "xxx.png",
"icon_kecil": "xxx.png",
"icon_besar": "xxx.png",
"is_background":true,
"tipe_push":1,
"timestamp":"27-10-2016 22:51:48",
  "payload":{
        "IMAGE_ID":"1",
        "IMAGE_TYPE":"5",
        "IMAGE_NAME":"SPLASH SCREEN",
        "IMAGE_PATH":"xxx.png"
    }
},
  "to" : "fK2iL7Ptp9I:APA91bEFxlLyEIpr-vO2Fw3VoTOY6t-38EV_Thnn_SddL17nu7E1VcjZVEgpOAE7vEKn83Cxz3q9rXAapUq-00opHbuOrcw7AwPtFtyYAFb674olwttVLuQgCIByN-i_gJJy8z6rjUi7"
}

这是我的logcat错误，当我试图解析JSON对象payload。

org.json.JSONException: Expected ':' after timestamp at character 128 of {"Data":{"judul_push":"pesan_push" ,"image_push":"icon_kecil","icon_besar":"icon_kecil","is_background":"tipe_push","timestamp"payload":{"IMAGE_ID":"IMAGE_TYPE" },{"IMAGE_NAME":"IMAGE_PATH"},{"IMAGE_SEQUENCE":"AKTIF"},{"posted_by":"posted_date"}}

Answer 1

有一个类似的问题，我从抱怨字符的地方删除了JSON数据，然后手工重新键入。不知怎么的，我有一个隐藏的性格。

Answer 2

我找到了答案。

答案是，首先，如果Firebase发送给我们JSON数据和任何JSON对象，我们需要将JSON数据解析为字符串，然后我们需要将JSON对象(payload)的字符串值转换为数据类型JSON对象。最后，我们可以在JSON对象(payload)中获得字符串值(image_id)。
