How do I Attach an AdaptiveCardFromJson in a LUIS Bot C#? - botframework

Question

I asked a similar question recently but wasn't specific enough. I see that there is some code with the AdaptiveCards NuGet Package to attach an AdaptiveCardFromJson and AdaptiveCardFromSDK, which under a the normal Microsoft Bot Model is available.
However, under the Microsoft LUIS Bot Model isn't an option, here's the code I have which returns an employee lookup result from a SQL DB Search:
[LuisIntent("Who_is_Employee")]
public async Task Who_is_EmployeeIntent(IDialogContext context, LuisResult result)
{
EntityRecommendation recommendation;
if (result.TryFindEntity("Communication.ContactName", out recommendation))
{
List<Employee> results = EmployeeService.FindEmployees(recommendation.Entity);
if (results.Count > 0)
{
string response = "";
foreach (Employee e in results)
{
string name = e.FullName;
string title = e.JobTitle;
response += " " + name + " " + title + "\n";
}
await context.PostAsync(response);
}
}
else
{
await context.PostAsync(" Sorry, I couldn't find who you were looking for.");
}
}
I would like that information to be returned as an AdaptiveCard, how do I achieve this?

Answer 1

Mark,
you need to craft your adaptive card either as json or using the SDK to create an instance of AdaptiveCard. Here is a great place to learn more about this.
Once you've crafted your card and have an instance of the AdaptiveCard class, you need to create a new message and attach the card to that message. The new message is what you'll post back to the user.
The code will look something like this
var card = AdaptiveCard.FromJson(<your json here>);
Attachment attachment = new Attachment()
{
ContentType = AdaptiveCard.ContentType,
Content = card
};
var myRespsonse = context.MakeMessage();
myRespsonse.Attachments.Add(attachment);
await context.PostAsync(myRespsonse, CancellationToken.None);

This was the code I ended up having to use to make this successful:
[LuisIntent("Who_is_Employee")]
public async Task Who_is_EmployeeIntent(IDialogContext context, LuisResult result)
{
EntityRecommendation recommendation;
if (result.TryFindEntity("Communication.ContactName", out recommendation))
{
List<Employee> results = EmployeeService.FindEmployees(recommendation.Entity);
if (results.Count > 0)
{
/* Single line per result */
/*
string response = "";
foreach (Employee e in results)
{
string name = e.FullName;
string title = e.JobTitle;
response += " " + name + " " + title + "\n";
}
await context.PostAsync(response);
*/
/* Adaptive card per result */
// Load json template
string physicalPath = System.Web.HttpContext.Current.Server.MapPath("../AdaptiveCards/EmployeeLookup.json");
string jsonTemplate = "";
using (StreamReader r = new StreamReader(physicalPath))
{
jsonTemplate = r.ReadToEnd();
}
var respsonse = context.MakeMessage();
foreach (Employee e in results)
{
string employeeJson = jsonTemplate;
employeeJson = employeeJson.Replace("{{FullName}}", e.FullName);
employeeJson = employeeJson.Replace("{{JobTitle}}", e.JobTitle);
employeeJson = employeeJson.Replace("{{Reference}}", e.Reference);
employeeJson = employeeJson.Replace("{{Phone}}", e.Phone);
employeeJson = employeeJson.Replace("{{Email}}", e.Email);
employeeJson = employeeJson.Replace("{{Mobile}}", e.Mobile);
AdaptiveCard card = AdaptiveCard.FromJson(employeeJson).Card;
Attachment attachment = new Attachment()
{
ContentType = AdaptiveCard.ContentType,
Content = card
};
respsonse.Attachments.Add(attachment);
}
await context.PostAsync(respsonse);
}
}
else
{
await context.PostAsync(" Sorry, I couldn't find who you were looking for.");
}
}
