如何从Messenger位置快速回复中接收位置 [英] How to receive the location from Messenger Location Quick reply
问题描述
我有这段代码，提示用户输入他们的位置. 我正在使用Botframework v4和C#.我将Messenger的快速回复放在附件提示中.
Hi i have this code that prompt the user for their location. I am using Botframework v4 and C#. I put the messenger quick reply in an attachment prompt.
if (response == "test location")
{
Activity reply = stepContext.Context.Activity.CreateReply();
reply.ChannelData = JObject.FromObject(
new
{
text = "loc",
quick_replies = new object[]
{
new
{
content_type = "location",
},
},
});
return await stepContext.PromptAsync(
ATTACHPROMPT,
new PromptOptions
{
Prompt = reply,
});
}
但是在用户发送其位置之后.机器人崩溃.我该如何处理位置信息的返回，使机器人不会崩溃?这是例外
But after the user send its location. The bot crashes. How can i handle the return of the location so the bot won't crash? Here is the exeption

推荐答案
当用户在Facebook Messenger中单击位置快速答复时，传入的活动没有text属性，该文本属性会导致值不能为空"错误致电LUIS时.这是BotFramework中目前已知的问题，并且开发团队目前正在努力解决这个问题.同时，在调用LUIS识别器之前，请检查并确保传入活动的text属性不为null或为空.
When the user clicks on the location quick reply in Facebook Messenger, the incoming activity does not have a text property which would cause a 'Value cannot be null' error when calling LUIS. This is currently a known issue in the BotFramework, and the development team is currently working to resolve this problem. In the meantime, check to make sure the incoming activity's text attribute is not null or empty before calling the LUIS recognizer.
if(!string.IsNullOrEmpty(turnContext.Activity.Text)) {
var luisResults = await _services.LuisServices[LuisConfiguration].RecognizeAsync(dc.Context, cancellationToken);
}
