Push notification 如何在MFP中的推送通知中发送促销图像

如下图所示，如何在推送通知中发送促销图像？我需要在有效负载中使用任何html代码吗？如果可能，请分享代码片段

编辑2019年4月：

IBM MobileFirst 8.0支持发送富推送通知。更新至最新的服务器端和客户端补丁包以获取该功能。分派推送时，请使用以下有效负载结构：

推送有效载荷：

{  
   "message":{  
      "alert":"Picture Notification for Android devices ",
      "url":"http://www.test.com"
   },
   "target":{  
      "deviceIds": ["MyDeviceId1", ...],
      "platforms": ["A,G", ...],
      "tagNames": ["Gold", ...],
      "userIds": ["MyUserId", ...]
   },
   "settings":{  
      "gcm":{  
         "style":{  
            "notification_type":"PICTURE_NOTIFICATION",
            "url":"<URL of the image that needs to be displayed>",
            "title":"Test"
         },
      "apns": {
         "attachmentUrl" : "http://test.com/test.png",
         "badge" : 1,
         "category" : 1,
         "iosActionKey" : "Ok",
         "launchImage" : "test.png",
         "locArgs" : [ "["Shelly"]", ... ],
         "locKey" : "REQ_FORMAT",
         "payload" : {"custom":"data"},
         "sound" : "song.mp3",
         "subtitle" : "Sub Title",
         "title" : "Title",
         "titleLocArgs" : [ "["Shelly"]", ... ],
         "titleLocKey" : "REQ_FORMAT",
         "type" : "SILENT"
        }
      }
   }
}

{
“电文”：{
“警报”：“Android设备的图片通知”，
“url”：”http://www.test.com"
},
“目标”：{
“设备ID”：[“MyDeviceId1”，…]，
“平台”：[“A，G”，…]，
“标记名”：[“黄金”，…]，
“userid”：[“MyUserId”，…]
},
“设置”：{
“gcm”：{
“风格”：{
“通知类型”：“图片通知”，
“url”：“，
“标题”：“测试”
},
“apns”：{
“附件URL”：http://test.com/test.png",
"徽章":一,，
"类别":一,，
“iosActionKey”：“确定”，
“launchImage”：“test.png”，
“locArgs”：[“[“Shelly”]，…]，
“locKey”：“请求格式”，
“有效负载”：{“自定义”：“数据”}，
“声音”：“song.mp3”，
“副标题”：“副标题”，
“头衔”：“头衔”，
“标题记录”：[“[“Shelly”]，…]，
“titleLocKey”：“请求格式”，
“类型”：“无提示”
}
}
}
}

我收到错误“错误请求-JSON验证在“gcm”失败”，JSON负载如下：-

{
  "settings": {
    "gcm": {
        "payload": {
          "action": "ACTION",
          "path": "/path"
        },
        "style":{  
            "notification_type":"PICTURE_NOTIFICATION",
            "url":"https://homepages.cae.wisc.edu/~ece533/images/airplane.png",
            "title":"RICH PUSH"
         }
    },
    "apns": {
      "payload": {
          "action": "ACTION",
          "path": "/path"
        }
    }
  },
  "message": {
    "alert": "Test MFP PUSH Notification."
  },
  "target": {
    "userIds" : ["11359164"]
  }
}

响应JSON:-

{
    "code": "FPWSE0011E",`enter code here`
    "message": "Bad Request - The JSON validation failed at 'gcm'."
}

我正在使用MFP8.0，请建议对上述JSON进行更改
