Bot Framework: Prompt 和 retry 提示信息同时出现
Bot Framework: Prompt and retry prompt messages appear at the same time
我向用户显示的提示包含提示消息和重试提示消息,请参见下文:
return await ctx.PromptAsync(CancelCurrentDialogsPrompt, new PromptOptions
{
Prompt = MessageFactory.Text("Are you sure you'd like to cancel?"),
Choices = ChoiceFactory.ToChoices(confirmationOptionsList),
RetryPrompt = MessageFactory.Text("Please select or type yes/no")
}, cancellationToken);
当我运行模拟器中的BOT时,提示信息和重试提示信息同时出现,这是我没想到的,见下图:
当我输入错误的选项时,重试提示按预期显示。从列表中选择正确的值后,对话将按预期继续,没有错误的对话。

我正在使用 bot.cs class
中的以下代码调用取消对话框
await dialogContext.BeginDialogAsync(nameof(CancelDialog));
调用时对话框堆栈上没有任何内容。这是我 CancelDialog.cs
中的代码
public class CancelDialog : ComponentDialog
{
public readonly BotDialogSet DialogSet;
private const string CancelWaterfallDialogs = "CancelWaterfallDialogs";
private const string CancelCurrentDialogsPrompt = "CancelCurrentDialogsPrompt";
public CancelDialog(BotDialogSet dialogSet) : base(nameof(CancelDialog))
{
DialogSet = dialogSet;
var waterfallSteps = new WaterfallStep[]
{
WouldYouLikeToCancel,
CompleteUsersSelectedAction
};
AddDialog(new WaterfallDialog(CancelWaterfallDialogs, waterfallSteps));
AddDialog(new ConfirmPrompt(CancelCurrentDialogsPrompt));
}
private static async Task<DialogTurnResult> WouldYouLikeToCancel (WaterfallStepContext ctx, CancellationToken cancellationToken)
{
return await ctx.PromptAsync(CancelCurrentDialogsPrompt, new PromptOptions
{
Prompt = MessageFactory.Text("Are you sure you'd like to cancel?"),
RetryPrompt = MessageFactory.Text("Are you sure you'd like to cancel? Please select or type yes/no")
}, cancellationToken);
}
private static async Task<DialogTurnResult> CompleteUsersSelectedAction(WaterfallStepContext ctx, CancellationToken cancellationToken)
{
if ((bool)ctx.Result)
{
await ctx.Parent.CancelAllDialogsAsync(cancellationToken);
return await ctx.EndBotDialogAsync(cancellationToken);
}
return await ctx.EndDialogAsync(cancellationToken: cancellationToken);
}
}
1- 定义如下:
AddDialog(new TextPrompt("YNValidator", YesNoValidator);
-在:
之后添加
AddDialog(new ConfirmPrompt(CancelCurrentDialogsPrompt));
2- 定义 YesOrNValidator:
private Task<bool>YorNValidator (PromptValidatorContext<string> promptContext, CancellationToken cancellationToken)
{
//Test the value... and pass true or false
Task.FromResult(true);
}
3- 接下来重写 WouldYouLikeToCancel
private static async Task<DialogTurnResult> WouldYouLikeToCancel (WaterfallStepContext ctx, CancellationToken cancellationToken)
{
var options= new PromptOptions
{
Prompt = MessageFactory.Text("Are you sure you'd like to cancel?"),
RetryPrompt = MessageFactory.Text("Are you sure you'd like to cancel? Please select or type yes/no")
}, cancellationToken);
return await stepContext.PromptAsync("YNValidator",options,cancellationToken);
}
