验证 FormFlow 中的字段

Question

Code

 [Serializable]
    public class FAQConversation
    {
        [Prompt("What product is your concern? {||}")]
        public VASetting.SupportedProducts Products { get; set; }
        [Prompt("Okay, tell me what is your question. Enter \"back\" to go back to Products Selection.")]
        public string Inquiry { get; set; }
        public static IForm<FAQConversation> BuildForm()
        {
            return new FormBuilder<FAQConversation>()
                .AddRemainingFields()
                .Field(new FieldReflector<FAQConversation>(nameof(Inquiry)).SetValidate(AnswerInquiry))
                .Message("Hi this is Test Virtual Assistant")
                .Build();
        }

        private static async Task<ValidateResult> AnswerInquiry(FAQConversation state, object value)
        {
            var asString = value as String;
            var vaConfig = new SmartCareSetting(state.Products);
            var result = new ValidateResult() { IsValid = false, Value = value };
            if (!string.IsNullOrEmpty(asString))
            {
                var luisService = new LuisService(new LuisModelAttribute(vaConfig.AppID, vaConfig.SubscriptionKey, domain: vaConfig.HostName));
                var luisResult = await luisService.QueryAsync(asString, CancellationToken.None);
                result.Feedback = luisResult.TopScoringIntent.Intent.ToString();
            }
            return result;
        }
    }

My bot code above shows the conversation below.

我正在使用 FormFlow 和 Bot Framework 创建一个简单的查询机器人。我正在通过 LUIS 验证 Inquiry 字段并返回处理意图。我得到了正确的意图，在这种情况下是 EXC01。之后，我想知道为什么我仍然收到 Inquiry 提示。

问题：
1. 询价意向确认后如何完成FormFlow？
2. 我想处理返回的Intent 但不想显示给用户。我将使用 Intent 字符串查询数据库。我可以在 BuildForm() 中执行此操作吗？

Answer 1

How can I finish the FormFlow after validating the Intent of the Inquiry?

在验证函数AnswerInquiry中，我们可以发现IsValid 属性 of ValidateResult 总是false，这导致了问题。将返回的意图分配为反馈后，您可以将 IsValid 属性设置为 true。以下代码片段适合我，你可以参考它。

private static async Task<ValidateResult> AnswerInquiry(FAQConversation state, object value)
{
    var asString = value as String;
    var vaConfig = new SmartCareSetting(state.Products);

    var result = new ValidateResult() { IsValid = false, Value = value };

    if (!string.IsNullOrEmpty(asString))
    {
        var luisService = new LuisService(new LuisModelAttribute(vaConfig.AppID, vaConfig.SubscriptionKey, domain: vaConfig.HostName));
        var luisResult = await luisService.QueryAsync(asString, CancellationToken.None);
        result.Feedback = luisResult.TopScoringIntent.Intent.ToString();

        //set IsValid to true
        result.IsValid = true;
    }
    return result;
}

I want to handle the returned Intent but not show it to the user. I'll be using the Intent string for querying to a Database. Can I do this inside the BuildForm()?

获取返回的意图后，如果您想根据返回的意图从数据库中查询记录，可以在验证函数中执行。
