我很难将这个facebook的通用模板转换为C#。我不确定我是否正确转换它。下面是我尝试的代码,但没有在Messenger上呈现。谢谢。
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[]
{
new
{
type = "element_share,",
share_contents = new
{

payload = new

},

});
await stepContext.Context.SendActivityAsync(previewReply);
elements
和buttons
属性需要是列表。看一下下面的示例模板。
var attachment = new
{
type = "template",
payload = new
{
template_type = "generic",
elements = new []
{
new {
title = "title",
image_url = "https://thechangreport.com/img/lightning.png",
subtitle = "subtitle",
buttons = new object[]
{
new {
type = "element_share",
share_contents = new {
attachment = new {
type = "template",
payload = new
{
template_type = "generic",
elements = new []
{
new {
title = "title 2",
image_url = "https://thechangreport.com/img/lightning.png",
subtitle = "subtitle 2",
buttons = new object[]
{
new {
type = "web_url",
url = "http://m.me/petershats?ref=invited_by_24601",
title = "Take Quiz"
},
},
},
},
},
}
},
},
},
},
},
},
};
reply.ChannelData = JObject.FromObject(new { attachment });
请注意,如果主模板与您尝试共享的模板不同,则只需在模板中添加share_contents
元素。否则,您的按钮可能只是new { type = "element_share" }
,这使得模板远没那么复杂。
此外,请确保Whitelist您的所有网址,并确保所有图片网址都正常工作 - 其中几个网站无法正常工作。如果URL未列入白名单且图像链接已断开,则不会呈现模板。
希望这可以帮助!
