如何阻止语言翻译 A​​pi 在机器人框架中翻译表单流输入

Question

    Code:
    public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
            {
                //trust Webchat &SMS channel
                MicrosoftAppCredentials.TrustServiceUrl(@"https://webchat.botframework.com", DateTime.MaxValue);
                MicrosoftAppCredentials.TrustServiceUrl(@"https://sms.botframework.com", DateTime.MaxValue);

                Trace.TraceInformation($"Incoming Activity is {activity.ToJson()}");

                if (activity.Type == ActivityTypes.Message)
                {
                    if (!string.IsNullOrEmpty(activity.Text))
                    {

                        //detect language of input text
                        var userLanguage = TranslationHandler.DetectLanguage(activity);

                        //save user's LanguageCode to Azure Table Storage
                        var message = activity as IMessageActivity;

                        try
                        {
                            using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, message))
                            {
                                var botDataStore = scope.Resolve<IBotDataStore<BotData>>();
                                var key = new AddressKey()
                                {
                                    BotId = message.Recipient.Id,
                                    ChannelId = message.ChannelId,
                                    UserId = message.From.Id,
                                    ConversationId = message.Conversation.Id,
                                    ServiceUrl = message.ServiceUrl
                                };
                                var userData = await botDataStore.LoadAsync(key, BotStoreType.BotUserData, CancellationToken.None);
                                var storedLanguageCode = userData.GetProperty<string>(StringConstants.UserLanguageKey);
                                //update user's language in Azure Table Storage

                                if (storedLanguageCode != userLanguage)
                                {
                                    userData.SetProperty(StringConstants.UserLanguageKey, userLanguage);
                                    await botDataStore.SaveAsync(key, BotStoreType.BotUserData, userData, CancellationToken.None);
                                    await botDataStore.FlushAsync(key, CancellationToken.None);
                                }
                            }
                        }
                        catch (Exception ex)
                        {
                            throw ex;
                        }
                        //translate activity.Text to English before sending to LUIS for intent
                        activity.Text = TranslationHandler.TranslateTextToDefaultLanguage(activity, userLanguage);
                        //await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
                        await Conversation.SendAsync(activity, MakeRoot);
                    }
                    else {
                        await Conversation.SendAsync(activity, MakeRoot);

                    }
                }
                else
                {
                    HandleSystemMessageAsync(activity);
                }
                var response = Request.CreateResponse(HttpStatusCode.OK);
                return response;
            }
            internal static IDialog<object> MakeRoot()
            {
                try
                {
                    return Chain.From(() => new RootDialog());
                }
                catch (Exception ex)
                {
                    throw ex;
                }
            }

我正在 Bot 框架中实现 Microsoft 语言翻译器，并且还实现了语言理解服务 (Luis)。在我的代码中，一旦用户向机器人发送消息，语言翻译器首先检测用户语言，然后在根对话框中将其发送到 LUIS（我的 LUIS 应用程序是英文），然后机器人将响应翻译回使用状态数据的用户语言。

在我使用表单流之前一切正常，机器人用户在表单流中的一些输入文本如果不是英语单词，则将被翻译成其他语言。请问如何在不删除语言翻译 A​​PI 的情况下更正此问题？

注意： 我的 RootDailog 中有一个部分调用了表单流。无论如何我可以阻止语言翻译器 API 翻译表单输入吗？

如果堆栈中的最后一个对话框是 FormFlow 对话框，您可以检查对话框堆栈而不进行翻译。比如：

bool translate = true;
using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, activity))
{
    var botData = scope.Resolve<IBotData>();
    await botData.LoadAsync(default(CancellationToken));

    var stack = scope.Resolve<IDialogTask>();
    if (stack.Frames != null && stack.Frames.Count > 0)
    {
        var lastFrame = stack.Frames[stack.Frames.Count - 1];
        var frameValue = lastFrame.Target.GetType().GetFields()[0].GetValue(lastFrame.Target);
        if (frameValue.GetType() == typeof(FormDialog<SandwichOrder>))
        {
            //in the FormFlow dialog ... do NOT translate
            translate = false;
        }
    }
}
if (translate)
{
    //translate activity.Text to English before sending to LUIS for intent
    activity.Text = TranslationHandler.TranslateTextToDefaultLanguage(activity, userLanguage);
}
await Conversation.SendAsync(activity, MakeRoot);
