我目前正在使用微软的Bot Framework制作聊天机器人。在我的流程中，我有一个最终对话框，告诉用户他们正在参与比赛。还有一个未知输入的错误处理方法。这两种方法如下所示：
[Serializable]
public class ConcertCityDialog : AbstractBasicDialog<DialogResult>
{
private static FacebookService FacebookService => new FacebookService(new FacebookClient());
[LuisIntent("ConcertCity")]
public async Task ConcertCityIntent(IDialogContext context, LuisResult result)
{
var fbAccount = await FacebookService.GetAccountAsync(context.Activity.From.Id);
var selectedCityName = result.Entities.FirstOrDefault()?.Entity;
concert_city selectedCity;
using (var concertCityService = new ConcertCityService())
{
selectedCity = concertCityService.FindConcertCity(selectedCityName);
}
if (selectedCity == null)
{
await NoneIntent(context, result);
return;
}
user_interaction latestInteraction;
using (var userService = new MessengerUserService())
{
var user = userService.FindByFacebookIdIncludeInteractions(context.Activity.From.Id);
latestInteraction = user.user_interaction.MaxBy(e => e.created_at);
}
latestInteraction.preferred_city_id = selectedCity.id;
latestInteraction.gif_created = true;
using (var userInteractionService = new UserInteractionService())
{
userInteractionService.UpdateUserInteraction(latestInteraction);
}
var shareIntroReply = context.MakeMessage();
shareIntroReply.Text = "Great choice! You are now participating in the competition. If you dare then pass your message \uD83D\uDE0E";
await context.PostAsync(shareIntroReply);
var reply = await MessageUtility.MakeShareMessageCard(context, fbAccount, latestInteraction, false);
await context.PostAsync(reply);
context.Done(DialogResult.Done);
}
[LuisIntent("")]
[LuisIntent("None")]
public async Task NoneIntent(IDialogContext context, LuisResult result)
{
messenger_user user;
using (var userService = new MessengerUserService())
{
user = userService.FindByFacebookId(context.Activity.From.Id);
}
var phrase = CreateMisunderstoodPhrase(user, result.Query);
using (var misunderstoodPhraseService = new MisunderstoodPhraseService())
{
misunderstoodPhraseService.CreatePhrase(phrase);
}
List<concert_city> concertCities;
using (var concertCityService = new ConcertCityService())
{
concertCities = concertCityService.GetUpcomingConcertCities().ToList();
}
// Prompt city
var reply = context.MakeMessage();
reply.Text = "I'm not sure what you mean \uD83E\uDD14<br/>Which Grøn Koncert would you like to attend?";
reply.SuggestedActions = new SuggestedActions
{
Actions = concertCities.Select(e => MessageUtility.MakeQuickAnswer(e.name)).ToList()
};
await context.PostAsync(reply);
context.Wait(MessageReceived);
}
protected override void OnDeserializedCustom(StreamingContext context)
{
}
}
以下是 AbstractBasicDialog 的实现：
[Serializable]
public abstract class AbstractBasicDialog<T> : LuisDialog<T>
{
protected AbstractBasicDialog() : base(new LuisService(new LuisModelAttribute(
ConfigurationManager.AppSettings["LuisAppId"],
ConfigurationManager.AppSettings["LuisAPIKey"],
domain: ConfigurationManager.AppSettings["LuisAPIHostName"])))
{
}
[LuisIntent("Cancel")]
public virtual async Task CancelIntent(IDialogContext context, LuisResult result)
{
var randomQuotes = new List<string>
{
"If you say so, I'll leave you alone for now",
"alright then, I'll leave you alone",
"Okay then, I won't bother you anymore"
};
await context.PostAsync(MessageUtility.RandAnswer(randomQuotes));
context.Done(DialogResult.Cancel);
}
[LuisIntent("Start")]
public virtual async Task StartIntent(IDialogContext context, LuisResult result)
{
context.Done(DialogResult.Restart);
}
[LuisIntent("CustomerSupport")]
public async Task CustomerSupportIntent(IDialogContext context, LuisResult result)
{
using (var userService = new MessengerUserService())
{
var user = userService.FindByFacebookId(context.Activity.From.Id);
if (user != null)
{
user.receiving_support = true;
userService.UpdateUser(user);
}
}
await context.PostAsync("I'll let customer service know, that you want to talk to them. They will get back to you within 24 hours.<br/>If at any time you want to return to me, and start passing a message, just type \"Stop customer support\".");
context.Call(new CustomerSupportDialog(), ResumeAfterCustomerSupport);
}
private async Task ResumeAfterCustomerSupport(IDialogContext context, IAwaitable<DialogResult> result)
{
context.Done(await result);
}
protected misunderstood_phrase CreateMisunderstoodPhrase(messenger_user user, string phrase)
{
return new misunderstood_phrase
{
phrase = phrase,
dialog = GetType().Name,
messenger_user_id = user.id
};
}
[OnDeserialized]
private void OnDeserialized(StreamingContext context)
{
OnDeserializedCustom(context);
}
protected abstract void OnDeserializedCustom(StreamingContext context);
}
调用链始于此对话框：

这通常是有效的。用户被告知他们的注册成功并且流程通过
context.Done()调用退出。然而，有时候聊天机器人没有将对话注册为已退出，就像在这里看到的那样：
Done()方法，聊天机器人仍然处于同一个对话中。这是我的聊天机器人普遍存在的问题，因为在所有对话框中有时都会发生这种情况。您有任何关于可能出错的输入吗？
编辑： 在调试时，我每次调用
context.Call都添加了断点。当我的问题出现时，它停止命中这些断点。这可能是某个DI的副作用吗？这是我的DI代码：Conversation.UpdateContainer(builder =>
{
builder.RegisterModule(new DialogModule());
builder.RegisterModule(new ReflectionSurrogateModule());
builder.RegisterModule(new DialogModule_MakeRoot());
builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly()));
var store = new TableBotDataStore(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);
builder.Register(c => store)
.Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
.AsSelf()
.SingleInstance();
builder.Register(c => new CachingBotDataStore(store,
CachingBotDataStoreConsistencyPolicy
.ETagBasedConsistency))
.As<IBotDataStore<BotData>>()
.AsSelf()
.InstancePerLifetimeScope();
builder.RegisterType<BasicLuisDialog>().As<LuisDialog<DialogResult>>().InstancePerDependency();
});
context.Done之后我们仍然看不到你正在做什么。 - Nicolas R
