Question

对于一个天蓝色的聊天机器人，我希望它在回答后问我一个简单的问题，所以我可以作为回报给出反馈。我正在使用HeroCard类。

对话

private async Task ShowWeatherResult(IDialogContext context, LuisResult result)
{
    bool found = false;
    foreach (var entity in result.Entities)
    {
        if (entity.Type.Equals(Entity_Location))
        {
            WeatherAPI weather = new WeatherAPI(entity.Entity);
            found = true;
            await context.PostAsync(weather.ForecastReport());
            await Task.Delay(500);

            // ask for happiness
            Attachment attachment = new Attachment()
            {
                ContentType = HeroCard.ContentType,
                Content = CardsBuilder.CreateHappinessCard()
            };
            var reply = context.MakeMessage();
            reply.Attachments.Add(attachment);
            await context.PostAsync(reply, CancellationToken.None);

            context.Wait(MessageReceivedAsync);
        }
    }
    if (!found)
    {
        await context.PostAsync($"I don't speak human fluently, try another question asking for a specific city!");
        context.Wait(MessageReceived);
    }
}


public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
{
    var message = await result;

    if (message.Text != null)
    {
        //
        var happiness = new HappinessAPI();

        // Got an Action Submit
        string value = message.Text;
        //string submitType = value.Type.ToString();
        switch (value)
        {
            case "ShowGif":
                await context.PostAsync(happiness.ShowGif(context), CancellationToken.None);
                await Task.Delay(500);
                break;
            case "HappinessSearch":
                await context.PostAsync(happiness.GetJoke(context), CancellationToken.None);
                await Task.Delay(500);
                break;
            default:
                break;
        }
    }

    context.Wait(MessageReceived);
}

HerdoCard

    internal static HeroCard CreateHappinessCard()
    {
        HeroCard card = new HeroCard()
        {
            Title = "Hi!",
            Text = "Are you happy?",
            Buttons = new List<CardAction>()
            {
                new CardAction()
                {
                    Title = "Yes",
                    Text = "Yes",
                    DisplayText = "Yes",
                    Type = ActionTypes.PostBack,
                    Value = "ShowGif"
                },
                new CardAction()
                {
                    Title = "Meh...",
                    Text ="No",
                    DisplayText = "Meh...",
                    Type = ActionTypes.PostBack,
                    Value = "HappinessSearch"
                }
            }

        };

        return card;
    }

happinessapi

public class HappinessAPI
{
    internal IMessageActivity ShowGif(IDialogContext context)
    {
        Attachment attachment = new Attachment()
        {
            ContentType = HeroCard.ContentType,
            Content = new HeroCard()
            {
                Images = new List<CardImage>()
                {
                    new CardImage("https://upload.wikimedia.org/wikipedia/commons/thumb/8/85/Smiley.svg/220px-Smiley.svg.png")
                }
            }
        };
        var reply = context.MakeMessage();
        reply.Attachments.Add(attachment);

        return reply;
    }

    internal IMessageActivity GetJoke(IDialogContext context)
    {
        var request = WebRequest.Create("http://api.icndb.com/jokes/random");
        request.ContentType = "application/json; charset=utf-8";
        string text;
        var response = (HttpWebResponse)request.GetResponse();

        using (var sr = new StreamReader(response.GetResponseStream()))
        {
            text = sr.ReadToEnd();
        }
        var reply = context.MakeMessage();
        reply.Text = (string)(JObject.Parse(text))["value"]["joke"];

        return reply;
    }
}

事实是，它在使用AzurePortal中的WebChat进行测试时有效，但对其问题的回复并不适用于微软团队。

样品： Works in Webchat:

我：法兰克福的天气

Bot：“这很冷......无论如何”

Bot：你开心吗？

我：点击“是/否”

Bot：发一个笑话或笑脸

Doesn't work in Microsoft Teams

一切顺利，直到我点击“是/否”，然后它只是做某事（“正在打字......”出现但在此之后，没有任何反应。

修改的

我在使用Microsoft Teams中的Chatbot时看到，当我点击herocard时，会在聊天中写入一条消息，但不应该，因为它已设置为ActionTypes.Postback

HeroCard现在看起来像这样：

internal static HeroCard CreateHappinessCard() { HeroCard card = new HeroCard() { Title = "Hi!", Text = "Are you happy?", Buttons = new List<CardAction>() { new CardAction() { Title = "Yes", Text = "ShowGif", //DisplayText = null, Type = ActionTypes.MessageBack, Value= "{\"action\": \"ShowGif\" }" }, new CardAction() { Title = "Meh...", Text ="HappinessSearch", //DisplayText = null, Type = ActionTypes.MessageBack, Value = "{\"action\": \"HappinessSearch\" }" } } }; return card; } }

但仍然无法正常工作。没有消息被发送回机器人。如果我使用imBack类型，但消息会显示在聊天中，我不想要的内容和messageBack应该有效。

编辑3 遵循提供的代码

对话框

private async Task ShowLuisResult(IDialogContext context, LuisResult result) { await context.PostAsync($"You have reached {result.Intents[0].Intent}. You said: {result.Query}"); context.Call(new HeroCardDialog(), MessageReceivedAsync); } public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result) { var message = await result; if (message != null) { // } //context.Wait(MessageReceived); context.Done<object>(null); }

HeroCardDialog

public class HeroCardDialog : IDialog<object> { public async Task StartAsync(IDialogContext context) { if (context == null) { throw new ArgumentNullException(nameof(context)); } //Set the Last Dialog in Conversation Data context.UserData.SetValue("HeroCardId", "HerdoCard Dialog"); var message = context.MakeMessage(); var attachment = GetHeroCard(); message.Attachments.Add(attachment); await context.PostAsync((message)); context.Done<object>(null); } private static Attachment GetHeroCard() { var heroCard = new HeroCard() { Title = "Hi!", Text = "Are you happy?", Buttons = new List<CardAction>() { new CardAction() { Title = "Yes", Text = "ShowGif", DisplayText = null, Type = ActionTypes.MessageBack, Value= "{\"msgback\" : \"ShowGif\"}" }, new CardAction() { Title = "Meh...", Text ="HappinessSearch", DisplayText = null, Type = ActionTypes.MessageBack, Value= "{\"msgback\" : \"HappinessSearch\"}" } } }; return heroCard.ToAttachment(); } }

Answer 1

Microsoft Teams不支持

PostBack。请查看Microsoft团队中的supported button activities列表。

我们建议您使用messageBack，因为您可以创建完全自定义的操作。

Chatbot不会在Microsoft Teams中发回消息
