在 Bot 框架中将 Facebook 通用模板的 JSON 代码转换为 C#

Question

我很难将这个通用的 facebook 模板转换为 C#。我不确定我是否正确转换了它。以下是我尝试但未在 Messenger 上呈现的代码。谢谢你。

    curl -X POST -H "Content-Type: application/json" -d '{

  "recipient":{

    "id":"<PSID>"

  },

  "message":{

    "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"

              }              

            ]      

          }

        ]

      }

    }

  }

}' "https://graph.facebook.com/v2.6/me/messages?access_token=<PAGE_ACCESS_TOKEN>"

这是我在 c# 中尝试过的，但它不起作用。我不确定我是否以正确的方式转换它。任何帮助将不胜感激，谢谢。

   Activity previewReply = stepContext.Context.Activity.CreateReply();

            previewReply.ChannelData = JObject.FromObject(

            new

            {

                attachment = new

                {

                    type = "template",

                    payload = new

                    {

                        template_type = "generic",

                        elements = new

                        {

                            title = "title",

                            subtitle = "subtitle",

                            image_url = "https://thechangreport.com/img/lightning.png",

                            buttons = new object[]

和 elements属性buttons需要是列表。看看下面的示例模板。var attachment = new{&nbsp; &nbsp; type = "template",&nbsp; &nbsp; payload = new&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; template_type = "generic",&nbsp; &nbsp; &nbsp; &nbsp; elements = new []&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; title = "title",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; image_url = "https://thechangreport.com/img/lightning.png",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; subtitle = "subtitle",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; buttons = new object[]&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; type = "element_share",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; share_contents = new {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; attachment = new {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; template_type = "generic",&nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; },};reply.ChannelData = JObject.FromObject(new { attachment });share_contents请注意，如果您的主模板与您尝试共享的模板不同，您只需向模板添加一个元素。否则，您的按钮只能是new { type = "element_share" }，这使得模板变得不那么复杂。此外，请务必将您的所有 URL列入白名单，并确保所有图像 URL 都能正常工作——其中有几个不能正常工作。如果 URL 未列入白名单且图像链接已损坏，则模板不会呈现。
