Facebook Messenger API:快速回复有效负载有什么作用？

Question

如果我发送Facebook快速回复JSON,如下所示:

"quick_replies":[
    {"content_type":"text","payload":"RED","title":"Red"},
    {"content_type":"text","payload":"BLUE","title":"Blue"},
    {"content_type":"text","payload":"GREEN","title":"Special"},
]

并且用户选择"特殊"回复,我回来了

{"recipient_id":5555,"text":"Special"}

我认为有效载荷字段的重点是提供一个除了标题之外的值,它将被发送回去,但似乎Facebook只是发送了所选答复的标题,这引出了一个问题......有什么意义呢？有效载荷场？

Answer 1

是的 - 你是对的,你应该对有效载荷做出如此回应.正如您在此处所见:https: //developers.facebook.com/docs/messenger-platform/send-api-reference/quick-replies#callback

答复应该是:

{
  "sender": {
    "id": "USER_ID"
  },
  "recipient": {
    "id": "PAGE_ID"
  },
  "timestamp": 1464990849275,
  "message": {
    "mid": "mid.1464990849238:b9a22a2bcb1de31773",
    "seq": 69,
    "text": "Red",
    "quick_reply": {
      "payload": "DEVELOPER_DEFINED_PAYLOAD_FOR_PICKING_RED"
    }
  }
}  

正如@Keith Coughtrey所说,你应该启用messaging_postbacks权限.
