"image_aspect_ratio" 从 Messenger BOT webview 分享时不尊重标记

Question

我正在尝试通过我的机器人的网络视图进行分享。这是我的代码

var messageToShare = {
            "attachment":{
              "type":"template",
              "payload":{
                "template_type":"generic",
                "image_aspect_ratio":"square",
                "elements":[
                   {
                    "title":"Welcome to Peter\'s Hats",
                    "subtitle":"We\'ve got the right hat for everyone.",
                    "image_url":"https://pbs.twimg.com/profile_images/735453447718338561/9W-MTtOo_400x400.jpg",
                    "buttons":[
                      {
                        "type":"web_url",
                        "url": "my share url",
                        "title":"View Website"
                      }
                    ]
                  }
                ]
              }
            }
        }
MessengerExtensions.beginShareFlow(
  function success() {},
  function error(errorCode, errorMessage) {},
  messageToShare,
  "broadcast"
);

共享正常，但未按预期发布图像。 "image_aspect_ratio" 标志不受尊重，图像以水平布局显示。

但同样的 JSON 在通过 CURL 完成共享时将图像显示为正方形。我的共享对象有问题吗？请帮助

您需要在负载中添加 "sharable":true：

var messageToShare = {
  "attachment":{
    "type":"template",
    "payload":{
      "template_type":"generic",
      "image_aspect_ratio":"square",
      "sharable": true,
      "elements":[
         {
          "title":"Welcome to Peter\'s Hats",
          "subtitle":"We\'ve got the right hat for everyone.",
          "image_url":"https://pbs.twimg.com/profile_images/735453447718338561/9W-MTtOo_400x400.jpg",
          "buttons":[
            {
              "type":"web_url",
              "url": "my share url",
              "title":"View Website"
            }
          ]
        }
      ]
    }
  }
}

这是 Messenger 平台上的错误。我向 Facebook 报告了这件事，现在它已经修复了。 https://developers.facebook.com/bugs/391245647960177/
