我已经开始在C＃和Microsoft Bot Framework中使用Bot Builder SDK处理我的聊天机器人。我已经部署了我的机器人，可以与它进行交互。目前我专注于Facebook Messenger。我已经可以使用Microsoft.Bot.Connector.Attachment在Messenger上显示卡片和按钮。您可以在Bot Connector Documentation中找到它。 现在我正在尝试实现自定义Facebook消息，但没有成功。 这是我的代码：
public async Task<Message> Post([FromBody]Message message)
{
if (message.Type == "Message")
{
message.BotPerUserInConversationData = null;
if (message.Text.Equals("test", StringComparison.InvariantCultureIgnoreCase))
{
var replyMessage = message.CreateReplyMessage();
replyMessage.ChannelData = new
{
notification_type = "NO_PUSH",
attachment = new
{
type = "template",
payload = new
{
template_type = "receipt",
recipient_name = "Stephane Crozatier",
order_number = "12345678902",
currency = "USD",
payment_method = "Visa 2345",
order_url = "http://petersapparel.parseapp.com/order?order_id=123456",
timestamp = "1428444852",
elements = new[]
{
new {
title = "Classic White T-Shirt",
subtitle = "100% Soft and Luxurious Cotton",
quantity = 2,
price = 50,
currency = "USD",
image_url = "http://petersapparel.parseapp.com/img/whiteshirt.png"
},
new
{
title = "Classic Gray T-Shirt",
subtitle = "100% Soft and Luxurious Cotton",
quantity = 1,
price = 25,
currency = "USD",
image_url = "http://petersapparel.parseapp.com/img/grayshirt.png"
}
},
address = new
{
street_1 = "1 Hacker Way",
street_2 = "",
city = "Menlo Park",
postal_code = "94025",
state = "CA",
country = "US"
},
summary = new
{
subtotal = 75.00,
shipping_cost = 4.95,
total_tax = 6.19,
total_cost = 56.14
},
adjustments = new[]
{
new {name = "New Customer Discount", amount = 20},
new {name = "$10 Off Coupon", amount = 10}
}
}
}
};
return replyMessage;
}
// return our reply to the user
try
{
return await Conversation.SendAsync(message, () => new EchoDialog());
}
catch (Exception exc)
{
return message.CreateReplyMessage(exc.Message);
}
}
else
{
return HandleSystemMessage(message);
}
}
例如，EchoDialog正在工作，我得到了结果。我可以在bot框架界面中获取数据。这是我从机器人那里得到的json：

有没有人设法让FB Messenger使用ChannelData显示模板？
更新：我从另一个fb帐户检查了它并成功获得了模板，但仅限第一次使用。接下来的每一次尝试都没有回应。
答案 0 :(得分：6)
你的代码很好，你是什么意思“每次下一次尝试都让我无法回答。”
我也为Messenger制作了BOT，它就像你一样工作。这是我的代码
public async Task<Message> Post([FromBody]Message message)
{
if (message.Type == "Message"){
Message ReplyMessage = message.CreateReplyMessage();
ReplyMessage.ChannelData = getFBFunctionMenu();
return ReplyMessage;
}else{return HandleSystemMessage(message);}
}
和我的功能：
public object getFBFunctionMenu(){
Models.Messenger fbmsg = new Models.Messenger();
fbmsg.ChannelData = new MessengerChannelData { notification_type = "NO_PUSH", attachment = new MessengerAttachment { payload = new MessengerPayload() } };
fbmsg.ChannelData.attachment.type = "template";
fbmsg.ChannelData.attachment.payload.template_type = "generic";
List<MessengerElement> e = new List<MessengerElement>();
List<MessengerButton> bs = new List<MessengerButton>();
bs.Add(new MessengerButton{type = "web_url",title = "Facebook",url ="http://www.facebook.com/"});
bs.Add(new MessengerButton{type = "web_url",title = "Google",url ="http://www.google.com/"});
bs.Add(new MessengerButton{type = "web_url",title = "Amazon",url ="http://www.amazon.com/"});
e.Add(new MessengerElement
{
title = "My Favorte Site",
subtitle = "some descript",
item_url = "http://localhost/",
image_url = "http://loalhost/img.png",
buttons = bs.ToArray()
});
fbmsg.ChannelData.attachment.payload.elements = e.ToArray();
return fbmsg.ChannelData;
}
我的型号代码：
namespace WiAdvance.BotConnector.Messenger.Models
{
public class Messenger
{
public MessengerChannelData ChannelData { get; set; }
}
public class MessengerChannelData
{
public string notification_type { get; set; }
public MessengerAttachment attachment { get; set; }
}
public class MessengerAttachment
{
public string type { get; set; }
public MessengerPayload payload { get; set; }
}
public class MessengerPayload
{
public string template_type { get; set; }
public MessengerElement[] elements { get; set; }
}
public class MessengerElement
{
public string title { get; set; }
public string subtitle { get; set; }
public string item_url { get; set; }
public string image_url { get; set; }
public MessengerButton[] buttons { get; set; }
}
public class MessengerButton
{
public string type { get; set; }
public string url { get; set; }
public string title { get; set; }
public string payload { get; set; }
}
}
