关于Microsoft Bot Framework,我们都知道Microsoft提供的samples。然而,这些样品通常具有“单一目的”,即Pizzabot仅用于订购比萨饼,等等。
事情是,我希望创造一个更复杂的Bot,它实际上回答了一系列事情。为此,我创建了一个“大厅”对话框,其中所有消息都使用此MessageController:
return await Conversation.SendAsync(message, () => new LobbyDialog());
在“Lobby”对话框中,我有一系列LUIS意图用于不同的事情,并且因为它根据意图选择任务,所以它很有效。
然而,对于更复杂的操作,我希望使用FormFlow机制,所以我可以使用像PizzaBot示例中的表单。问题是所有采样的“表单机器人”始终使用此消息控制器类型:
return Chain.From(() => new PizzaOrderDialog(BuildForm)
在同一个MessagesController中,建立构建器流程,如下所示:
var builder = new FormBuilder<PizzaOrder>();
ActiveDelegate<PizzaOrder> isBYO = (pizza) => pizza.Kind == PizzaOptions.BYOPizza;
ActiveDelegate<PizzaOrder> isSignature = (pizza) => pizza.Kind == PizzaOptions.SignaturePizza;
ActiveDelegate<PizzaOrder> isGourmet = (pizza) => pizza.Kind == PizzaOptions.GourmetDelitePizza;
ActiveDelegate<PizzaOrder> isStuffed = (pizza) => pizza.Kind == PizzaOptions.StuffedPizza;
return builder
// .Field(nameof(PizzaOrder.Choice))
.Field(nameof(PizzaOrder.Size))
.Field(nameof(PizzaOrder.Kind))
.Field("BYO.Crust", isBYO)
.Field("BYO.Sauce", isBYO)
.Field("BYO.Toppings", isBYO)
.Field(nameof(PizzaOrder.GourmetDelite), isGourmet)
.Field(nameof(PizzaOrder.Signature), isSignature)
.Field(nameof(PizzaOrder.Stuffed), isStuffed)
.AddRemainingFields()
.Confirm("Would you like a {Size}, {BYO.Crust} crust, {BYO.Sauce}, {BYO.Toppings} pizza?", isBYO)
.Confirm("Would you like a {Size}, {&Signature} {Signature} pizza?", isSignature, dependencies: new string[] { "Size", "Kind", "Signature" })
.Confirm("Would you like a {Size}, {&GourmetDelite} {GourmetDelite} pizza?", isGourmet)
.Confirm("Would you like a {Size}, {&Stuffed} {Stuffed} pizza?", isStuffed)
.Build()
;
我的重要问题是,是否可以使用我使用的MessagesController开始对话,然后在LobbyDialog中,使用触发Form的Intent并返回它?也就是说,从对话框开始流程?或者最好使用DialogChains吗?
因为,根据我的尝试,似乎我只能使用我描述的方法从MessagesController类调用它们,即Microsoft在Pizzabot中如何对其进行采样。
感谢您对此事的任何帮助或意见。谢谢你的时间。

当然可以!从对话框中实例化表单是一种非常常见的情况。为此,您可以在LUIS intent方法中执行以下操作:
var form = new FormDialog<YourFormModel>(
<ExistingModel>,
<TheMethodThatBuildTheForm>,
FormOptions.PromptInStart,
result.Entities);
context.Call(form, <ResumeAfterCallback>);
使用PizzaBot示例,它应该如下所示:
var form = new FormDialog<PizzaOrder>(
null,
BuildForm,
FormOptions.PromptInStart,
result.Entities);
context.Call(form, <ResumeAfterCallback>);
在ResumeAfterCallback中,您通常会获得表单的结果,捕获异常并执行上下文。等等,以便对话框可以继续接收消息。下面是一个简单的例子:
private async Task ResumeAfterCallback(IDialogContext context,
IAwaitable<PizzaOrder> result)
{
try
{
var pizzaOrder = await result;
// do something with the pizzaOrder
context.Wait(this.MessageReceived);
}
catch (FormCanceledException<PizzaOrder> e)
{
string reply;
if (e.InnerException == null)
{
reply = "You have canceled the operation. What would you like to do next?";
}
else
{
reply = $"Oops! Something went wrong :(. Technical Details: {e.InnerException.Message}";
}
await context.PostAsync(reply);
context.Wait(this.MessageReceived);
}
}
