bots - Facebook 信使平台 : generic template with quick replies

Question

我在看一些非常流行的机器人，比如“卫报”，我注意到每当你从它那里得到一个通用的模板回复时，它也会显示一些快速回复按钮(见附图)。 “The Guardian Bot”是如何做到这一点的？他如何结合快速回复和通用模板？一定是涉及到两条消息。

这在 Dialogflow 中对我有用，在后端返回类似的 Json 对象以实现结果:

 {
  "facebook": {
    "attachment":{
      "type":"template",
      "payload":{
        "template_type":"generic",
        "elements":[
           {
            "title":"Welcome!",
            "image_url":"https://petersfancybrownhats.com/company_image.png",
            "subtitle":"We have the right hat for everyone.",
            "default_action": {
              "type": "web_url",
              "url": "https://petersfancybrownhats.com/view?item=103",
              "webview_height_ratio": "tall"
            },
            "buttons":[
              {
                "type":"web_url",
                "url":"https://petersfancybrownhats.com",
                "title":"View Website"
              },{
                "type":"postback",
                "title":"Start Chatting",
                "payload":"DEVELOPER_DEFINED_PAYLOAD"
              }              
            ]      
          }
        ]
      }
    },
     "quick_replies":[
      {
        "content_type":"text",
        "title":"Search",
        "payload":"<POSTBACK_PAYLOAD>",
        "image_url":"http://example.com/img/red.png"
      },
      {
        "content_type":"location"
      }
    ]
  }
}
