Facebook Messenger API：發送結構化消息

Question

遵循這個例子 。

messageData = {
"attachment": {
  "type": "template",
  "payload": {
    "template_type": "generic",
    "elements": [{
      "title": "First card",
      "subtitle": "Element #1 of an hscroll",
      "image_url": "http://messengerdemo.parseapp.com/img/rift.png",
      "buttons": [{
        "type": "web_url",
        "url": "https://www.messenger.com/",
        "title": "Web url"
      }, {
        "type": "postback",
        "title": "Postback",
        "payload": "Payload for first element in a generic bubble",
      }],
    },{
      "title": "Second card",
      "subtitle": "Element #2 of an hscroll",
      "image_url": "http://messengerdemo.parseapp.com/img/gearvr.png",
      "buttons": [{
        "type": "postback",
        "title": "Postback",
        "payload": "Payload for second element in a generic bubble",
      }],
    }]
  }
}

我收到錯誤：

\\“error \\”：{\\“message \\”：\\“（＃100）不完整的元素數據：標題和至少一個其他字段（圖片網址，字幕或按鈕）是非空值\\”，\\“類型\\ “：\\” OAuthException \\”，\\ “代碼\\”：100，\\ “fbtrace_id \\”：\\ “ElbXaF25 + 0G \\”}

我錯過了什么嗎？ 在我看來，所有相關領域都存在。

Answer 1

想出來，用紅寶石寫這個，我需要在發送之前在哈希上調用to_json 。

Answer 2

是的，在發送之前需要轉換為json格式要么是結構化消息，要么是短信。
