自适应卡中的SubmitAction操作（botframework，c＃，emulator，localhost）我得到了这个例外
Exception: Value cannot be null. Parameter name: stringToEscape
[File of type 'text/plain']
card.Actions.Add(
new SubmitAction()
{
Title = "Submit"
Data = Newtonsoft.Json.Linq.JObject.FromObject(new { button = "Submit", ServerUrl = "idServerURL" })
}
);
来自RootDialog - 称为LUIS Intent
[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)

答案 0 :(得分：2)
尝试填写DataJson属性而不是Data属性。
var submitActionData = JObject.Parse("{ \"Type\": \"HotelSelection\" }");
var action = new SubmitAction()
{
DataJson = submitActionData.ToString()
}
除了完整的例外，问题出在LUIS周围，而不是自适应卡。具体来说，问题出现在BuildUri类的LuisService方法中（由LuisDialog调用）。例外情况还告诉我们，在调用EscapeDataString方法时会出现问题。
如果仔细查看BuildUri方法，您会看到有10次调用EscapeDataString方法。其中一些调用是针对服务本身的值，我认为你不会修改它们;但是其他值超过LuisModel的值，例如SubscriptionKey和ModelId，并且Query上还有一个值要发送到LUIS。
话虽如此，我的建议是检查您在LuisModel属性中设置的值，该属性正在装饰基于LuisDialog的类。
如果您不确定LUIS + Bot Framework的工作原理，我建议您查看intelligence-LUIS示例。
答案 1 :(得分：0)
您收到此错误，因为当您单击Adaptive卡上的提交按钮时，它会调用BOT Framework的POST方法。那时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，则不应该调用LUIS进行意图检查。

这就是我所做的，以使其适用于Microsoft团队。否则，只需在Data中传递一个字符串即可。
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
};
