[英]Botframework - C# - Adaptive Card - Submit Action - Exception

問題描述

在自適應卡片（botframework、c#、模擬器、本地主機）中的 SubmitAction 操作上，我收到此異常

Exception: Value cannot be null. Parameter name: stringToEscape
[File of type 'text/plain']

你能幫我指出我做錯了什么嗎？

card.Actions.Add(
    new SubmitAction()
    {
        Title = "Submit"
        Data = Newtonsoft.Json.Linq.JObject.FromObject(new { button = "Submit", ServerUrl = "idServerURL" })
    }
);

從 RootDialog - LUIS Intent 被調用

[LuisIntent("ServerAuth")]
public async Task ServerAuthIntentActionResultHandlerAsync(IDialogContext 
context, IAwaitable<IMessageActivity> activity, LuisResult result)
{
    var message = await activity;
    await context.PostAsync($"Am working on it...'{message.Text}' ");

    var serverAuthAction = new ServerAuthAction();

    // Action to execute if no form is required - Based on LUIS result, call fulfillment methods From/To ERP Data and proceed to next stage of dialog
    await serverAuthAction.ResumeActionServerAuthFormDialog(context, result);

    //context.Wait(this.MessageReceived);

}

public async Task ResumeActionServerAuthFormDialog(IDialogContext context, LuisResult result)
{
    try
    {
        //Based on the LUIS Result, fetch data from AppServer
        //var searchQuery =  result;

        //Data - Assign value to this Model from AppServer fetched data
        ServerAuthModel serverAuthData = new ServerAuthModel();
        serverAuthData = default(ServerAuthModel);

        //For testing populate values by hardcoding - /May/2017
        ServerAuthAdaptiveCardView serverAuthView = new ServerAuthAdaptiveCardView();

        //Pass Data to Channel Adaptive Card View 
        var resultData = serverAuthView.GetServerAuthAdaptiveCard();

        var resultMessage = context.MakeMessage();

        resultMessage.Attachments.Add(resultData);

        await context.PostAsync(resultMessage);
    }
    catch (Exception ex)
    {
        ...
    }
    finally
    {
        ....
    }
}

GetServerAuthAdaptiveCard() 具有提交操作代碼。

public Attachment GetServerAuthAdaptiveCard()
{
    AdaptiveCard card = new AdaptiveCard();
    card.FallbackText = "App Server Authentication";
    card.Body.Add(
        new TextInput()
        {
            Id = "idServerURL",
            IsRequired = true,
            Placeholder = "App Server URL",
            MaxLength = 100,
            IsMultiline = false,
            Style = TextInputStyle.Url,
            Speak = "App Server URL",
        });

    card.Body.Add(
        new ChoiceSet()
        {
            Id = "idAuthCompany",
            IsRequired = true,
            IsMultiSelect = false,
            Style = ChoiceInputStyle.Compact,
            Speak = "Company to Authenticate for",
            Value = "DocM5",
            Choices = new List<Choice>() {
                new Choice()
                {
                    Title = "P2PDemo",
                    Value = "P2PDemo",
                    IsSelected = true,
                    Speak = "P2PDemo"
                },
                new Choice()
                {
                    Title = "SalesDemo",
                    Value = "SalesDemo",
                    IsSelected = false,
                    Speak = "SalesDemo"
                }
            }
        });
    card.Body.Add(
        new TextInput()
        {
            Id = "idBranchName",
            IsRequired = true,
            Placeholder = "App Branch",
            MaxLength = 100,
            IsMultiline = false,
            Style = TextInputStyle.Text,
            // Value = ""
        });

    var submitActionData = JObject.Parse("{ \"Type\": \"idServerURL\" }");


    card.Actions.Add(
        /*  new SubmitAction()
        {
            Title = "Submit",
            // Speak = "Submit",
            Data = Newtonsoft.Json.Linq.JObject.FromObject(new { button = "Submit", ServerUrl = "idServerURL" })
        }
        */
        new SubmitAction()
        {
            DataJson = submitActionData.ToString()
        });

    var attachment = new Attachment() { ContentType = AdaptiveCard.ContentType, Content = card };
    return attachment;
}

3 個解決方案

解決方案1
 2  2017-05-31 09:31:38

嘗試填充DataJson屬性而不是Data屬性。

var submitActionData = JObject.Parse("{ \"Type\": \"HotelSelection\" }");

var action = new SubmitAction()
{
    DataJson = submitActionData.ToString()
}

根據添加到問題中的新詳細信息進行更新。

根據完整的例外情況，問題出在 LUIS 上，而不是 Adaptive 卡上。 具體來說，問題出在LuisService類（由LuisDialog ）的BuildUri方法中。 異常還告訴我們問題是在調用EscapeDataString方法時發生的。

如果您仔細查看BuildUri方法，您將看到有 10 次調用EscapeDataString方法。 其中一些調用與服務本身的值相反，我認為您沒有修改這些值； 然而，其他的超過了LuisModel值，比如SubscriptionKey和ModelId ，並且還有一個超過了要發送到LUIS的Query 。

話雖如此，我的建議是查看您在裝飾基於LuisDialog的類的LuisModel屬性中設置的值。

如果您不確定 LUIS + Bot Framework 的工作原理，我建議您查看智能 LUIS示例。

您收到此錯誤是因為當您單擊 Adaptive 卡上的提交按鈕時，它會調用您的 BOT 框架的 POST 方法。 此時Activity.Text字段為NULL 。 如果Activity.Text字段為NULL ，您應該檢查 POST 方法； 如果是，則不應調用 LUIS 進行意圖檢查。

我就是這樣做的，以使其適用於 Microsoft 團隊。 否則對於模擬器，您只需在 Data 中傳遞一個字符串。

dynamic dataObject = new JObject();
dataObject.msteams = new JObject();
dataObject.msteams.type = "imBack";
dataObject.msteams.value = intent.Value;
var actionSubmit = new AdaptiveSubmitAction(){
    Title = intent.Value,
    Data = turnContext.Activity.ChannelId != "emulator" ?  dataObject : intent.Value
};
