Messenger bot中发生PromptDialog错误 [英] PromptDialog error occurs in Messenger bot
问题描述
我的Messenger bot中的PromptDialog出现问题，每当到达提示对话框时，都会引发"Bot Code has an Error".我尝试将其移至代码周围，但无论将其放置在何处，它仍会抛出该错误，我尝试将其放入其自己的方法中，只是调用该方法并将上下文传递给它，但再次它没有帮助
I'm having an issue with a PromptDialog in my messenger bot, Whenever it reaches the prompt dialog it throws a "Bot Code has an Error". I've tried moving it around the code but it still throws it no matter where I put it, I've tried to place it into its own method and simply call the method and pass the context to it but again it didn't help.
我认为可能是LocationReceivedAsync中的某物，但是我不确定是什么.
I think it may be something in the LocationReceivedAsync however I'm not sure what.

推荐答案
LocationReceivedAsync的实现中有一个错误:在获得位置时，不应在方法的末尾放置context.Done(location).它应该在else语句上.
There is an error in your implementation of LocationReceivedAsync: you should not put a context.Done(location) at the end of the method when you got a location. It should be on an else statement.
此context.Done试图完成当前对话框，而您仍在尝试执行操作(在您的情况下要求更改半径).
This context.Done is trying to complete the current dialog whereas you are still trying to do actions (in your case asking for a radius change).
更正:
private async Task LocationReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument)
{
var reply = context.MakeMessage();
reply.AttachmentLayout = AttachmentLayoutTypes.Carousel;
reply.Attachments = new List<Attachment>();
List<CardImage> images = new List<CardImage>();
InfoClass IC = new InfoClass();
var msg = await argument;
var location = msg.Entities?.FirstOrDefault(e => e.Type == "Place");
if (location != null)
{
latitude = location.Properties["geo"]?["latitude"]?.ToString();
longitude = location.Properties["geo"]?["longitude"]?.ToString();
LocationObject[] StoreLocations = IC.NearBy(latitude, longitude, Radius, context);
int count = StoreLocations.Length;
for (int z = 0; z < count; z++)
{
CardImage Ci = new CardImage("https://maps.googleapis.com/maps/api/staticmap?size=764x400¢er=" + StoreLocations[z].Latitude + "," + StoreLocations[z].Longitude + "&zoom=15&markers=" + StoreLocations[z].Latitude + "," + StoreLocations[z].Longitude);
images.Add(Ci);
HeroCard hc = new HeroCard()
{
Title = StoreLocations[z].StoreName,
Subtitle = StoreLocations[z].Subtitle,
Images = new List<CardImage> { images[z] },
Buttons = new List<CardAction>()
};
CardAction ca = new CardAction()
{
Title = "Show Me",
Type = "openUrl",
Value = "https://www.google.co.za/maps/search/" + StoreLocations[z].Latitude + "," + StoreLocations[z].Longitude
};
hc.Buttons.Add(ca);
reply.Attachments.Add(hc.ToAttachment());
}
await context.PostAsync(reply);
PromptDialog.Confirm(context, PromtDecision, "Would You Like To Change The Search Radius ?", attempts: 100);
}
// Change is here
else
{
context.Done(location);
}
}
关于您的实现的另外一点.我不明白为什么要在RadiusPrompt之后重用它(在此处看不到实现，但为什么要在Facebook提示符(LocationReceivedAsync)的回调中使用搜索和结果显示"代码(在LocationObject[] StoreLocations = IC.NearBy(latitude, longitude, Radius, context); ...附近)?我想这就是您不希望做的事?).
one more point about your implementation. I don't understand why your "search and results display" code (around LocationObject[] StoreLocations = IC.NearBy(latitude, longitude, Radius, context);...) is in the callback from Facebook prompt (LocationReceivedAsync) if you want to reuse it after the RadiusPrompt (implementation not visible here but I guess it's what you would like to do no?).
也许您应该在此方法中保留latitude和longitude设置，然后调用一个也可以从RadiusPrompt调用的新方法
Maybe you should keep latitude and longitude setup in this method, and then call a new method that can also be called from your RadiusPrompt
