Attribute to define a route that handles Teams message extension query link (link unfurling) events.
public TeamsQueryLinkRouteAttribute(bool isAgenticOnly = false, ushort rank = 32767, string signInHandlers = default);new Microsoft.Agents.Extensions.MSTeams.MessageExtensions.TeamsQueryLinkRouteAttribute : bool * uint16 * string -> Microsoft.Agents.Extensions.MSTeams.MessageExtensions.TeamsQueryLinkRouteAttributePublic Sub New (Optional isAgenticOnly As Boolean = false, Optional rank As UShort = 32767, Optional signInHandlers As String = Nothing)Parameters
- isAgenticOnly
- Boolean
When true, the route only fires for agentic turns. Defaults to false.
- rank
- UInt16
Route evaluation order. Lower values run first. Defaults to Unspecified.
- signInHandlers
- String
A comma/space/semicolon-delimited list of OAuth sign-in handler names, or the name of an instance method on the agent class matching Func<ITurnContext, string[]>.
Remarks
Decorate a method with this attribute to register it as a handler for message extension link unfurling events in Teams. The method must match the QueryLinkHandler delegate signature.
[TeamsQueryLinkRoute]
public async Task<Response> OnQueryLinkAsync(ITeamsTurnContext turnContext, ITurnState turnState, string url, CancellationToken cancellationToken)
{
var preview = await _service.FetchPreviewAsync(url, cancellationToken);
var attachment = preview.ToCard().ToMessagingExtensionAttachment();
return new Response { ComposeExtension = new Result { Type = ResultType.List, Attachments = [attachment] } };
}
Alternatively, OnQueryLink(QueryLinkHandler, String[], UInt16) can be used to register the handler via the fluent API.
