聊天机器人不在 Microsoft Teams 中发回消息

Question

对于 azure 聊天机器人，我希望它在回答后问我一个简单的问题，这样我就可以在 return 中提供反馈。我正在使用 HeroCard class.

对话框

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 AzurePortal 中使用 WebChat 进行测试时有效，但对其问题的回复在 Microsoft 团队中没有。

样本： Works in Webchat:

我：法兰克福的天气

机器人："It's cold.... whatever"

机器人：你开心吗？

我：点击"yes/no"

Bot：发送笑话或笑脸

Doesn't work in Microsoft Teams

一切正常，直到我单击 "yes/no"，然后它尝试做一些事情（"is typing..." 出现，但在那之后，没有任何反应。

我在 Microsoft Teams 中使用 Chatbot 时看到，当我单击 herocard 时，一条消息被写在聊天中，而实际上它不应该，因为它被设置为 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;
    }
}

但还是不行。没有消息被发送回机器人。如果我使用 imBack 键入它，但消息出现在聊天中，我不想要和 messageBack 应该工作。

编辑 3 按照提供的代码

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 Teams 中 supported button activities 的列表。

我们建议您使用 messageBack，因为您可以创建完全自定义的操作。
