Azure Function 2.x - Get Current User's Claims

Question

I have an Azure Function 2.x (Asp.net Core) and am authenticating with Azure AD. I'm trying to access the logged-in user's Claims after authentication. Previously using Azure Functions 1.x we would get the Claims using ClaimsPrincipal.Current, as seen in the code below:

using System.Net;
using System.Collections.Generic;
using System.Security.Claims; 
using Microsoft.IdentityModel.Clients.ActiveDirectory; 

public static HttpResponseMessage Run(HttpRequestMessage req, out object document, TraceWriter log)
{
    string name = ClaimsPrincipal.Current.FindFirst("name").Value; 

    log.Info($"name is {name}");

    return req.CreateResponse(HttpStatusCode.OK, "Done");
}   

Any guidance on how we access Claims in Azure Functions 2.x using .Net Core?

Answer 1

This feature is now supported in C# in Azure Functions 2.0. You can now add ClaimsPrincipal as a parameter to your HttpTrigger function's signature, or you can access it on the HttpRequest object via req.HttpContext.User.

Support should be coming soon to JavaScript, and eventually all languages should support this feature.
