在 Adaptive Cards (botframework, c#, emulator, localhost) 中的 SubmitAction 操作我得到这个异常

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

你能帮我指出做错了什么吗？ 

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

从 RootDialog - LUIS Intent 被调用

[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() 具有提交操作代码。

public Attachment GetServerAuthAdaptiveCard()
{
    AdaptiveCard card = new AdaptiveCard();
    card.FallbackText = "App Server Authentication";
    card.Body.Add(
        new TextInput()

            Style = TextInputStyle.Url,
            Speak = "App Server URL",
        });

    card.Body.Add(
        new ChoiceSet()
        {
            Id = "idAuthCompany",
            IsRequired = true,

                    Value = "P2PDemo",
                    IsSelected = true,

                {
                    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;
}

尝试填充DataJson属性而不是属性Data。

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

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

根据添加到问题的新详细信息进行更新。

根据完整的例外情况，问题在于 LUIS 而不是自适应卡。具体来说，问题出在LuisService类的BuildUri方法中（由 调用）。该异常还告诉我们在调用EscapeDataString方法时发生了问题。LuisDialog

如果您仔细查看该BuildUri方法，您会看到该方法有 10 次调用EscapeDataString。其中一些调用违反了服务本身的值，我认为您没有修改它们；然而，其他的超过了LuisModel, like SubscriptionKeyand的值，ModelId并且还有一个超过 的Query要发送到LUIS。

话虽如此，我的建议是查看您在装饰基础类的LuisModel属性中设置的值。LuisDialog

如果您不确定 LUIS + Bot Framework 的工作原理，我建议您查看Intelligence-LUIS示例。

您收到此错误是因为当您单击自适应卡上的提交按钮时，它会调用您的 BOT 框架的 POST 方法。此时Activity.Text字段为NULL。如果Activity.Text字段为NULL;您应该检查 POST 方法 如果是，则不应调用 LUIS 进行意图检查。

我就是这样做的，以使其适用于 Microsoft 团队。否则对于模拟器，您只需在 Data 中传递一个字符串。

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
};
