是否可以将AdaptiveTextBlock占位符值作为参数列表发送到web api调用

Posted 2021-04-28

在机器人中，我们有一个自适应卡，用户可以选择是或否。选择“是”时，系统会提示用户输入关键字。在用户在自适应卡中的文本块中给出输入之后，必须捕获输入并将其作为输入参数发送到web api。

用户输入将在AdaptiveTextInput块的占位符中给出。

    public static Attachment GetUserInputForCustomPPT()
    {
        AdaptiveCard card = new AdaptiveCard()
        {
            Id = "GetCustomPPT",
            Body = new List<AdaptiveElement>()
            {
                new AdaptiveTextBlock()
                {
                    Text = "Do you want to apply filter and customise the PPT?",
                    Wrap=true,
                   Size = AdaptiveTextSize.Small
                },
                new AdaptiveContainer()
                {
                    Id = "getCustomPPTNo",
                    SelectAction = new AdaptiveSubmitAction()
                   {

答案

使用路由，您可以在路由本身上传递多个参数，也可以通过模型绑定或内容值绑定传递查询字符串上的参数。对于大多数常见情况，这实际上非常有效。只要您通过POST操作传递单个复杂类型，或通过查询字符串或POST缓冲区传递多个简单类型，就没有问题。但是如果你需要传递多个参数，就像使用WCF REST或ASP.NET AJAX一样容易做到的事情就不那么明显了。

RouteTable.Routes.MapHttpRoute(
name: "ApiName",
routeTemplate: "photos/**{action}**/{title}",
defaults: new {
    title = RouteParameter.Optional,
    controller = "PhotoApi",
    **action =** **"GetPhotos"** });

另一答案

是的，您可以从AdaptiveCard检索输入值，并将它们用作对API的HTTP请求中的参数。当用户提交AdaptiveCard时，输入字段将通过Value属性中的活动发送到bot。您可以使用JObject解析生成的JSON字符串，并检索API调用的值。请参阅下面的示例。

public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{

    if (turnContext.Activity.Type == ActivityTypes.Message)
    {   
        // Check if user submitted AdaptiveCard input
        if (turnContext.Activity.Value != null) {

            // Convert String to JObject
            String value = turnContext.Activity.Value.ToString();
            JObject results = JObject.Parse(value);

            // Get type from input field
            String name = results.GetValue("Type").ToString();

            // Get Keywords from input field
            String userInputKeywords = "";
            if (name == "GetPPT") {
                    userInputKeywords = results.GetValue("GetUserInputKeywords").ToString();
            }

            // Make Http request to api with paramaters
            String myUrl = $"http://myurl.com/api/{userInputKeywords}";

            ...

            // Respond to user
            await turnContext.SendActivityAsync("Respond to user", cancellationToken: cancellationToken);
        } else {
            // Send user AdaptiveCard
            var cardAttachment = GetUserInputForCustomPPT();
            var reply = turnContext.Activity.CreateReply();
            reply.Attachments = new List<Attachment>() { cardAttachment };
            await turnContext.SendActivityAsync(reply, cancellationToken);
        }
    }
}

希望这可以帮助！
