Bringing AuthorizeAttribute Behavior to Azure Functions v3

It hooks into .NET Core dependency injection container to enable authentication and authorization in the same way ASP.NET Core does.

Using the package

Installing the package

dotnet add package DarkLoop.Azure.Functions.Authorize

Setting up authentication

The goal is to utilize the same authentication framework provided for ASP.NET Core

using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using MyFunctionAppNamespace;

[assembly: FunctionsStartup(typeof(Startup))]
namespace MyFunctionAppNamespace
  class Startup : FunctionsStartup
    public void Configure(IFunctionsHostBuilder builder)
        .AddAuthentication(options =>
          options.DefaultAuthenticationScheme = JwtBearerDefaults.AuthenticationScheme;
          options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        .AddOpenIdConnect(options =>
          options.ClientId = "<my-client-id>";
          // ... more options here
        .AddJwtBearer(options =>
          options.Audience = "<my-audience>";
          // ... more options here

        .AddAuthorization(options =>
          options.AddPolicy("OnlyAdmins", policyBuilder =>
            // configure my policy requirements

No need to register the middleware the way we do for ASP.NET Core applications.

Using the attribute

And now lets use FunctionAuthorizeAttribute the same way we use AuthorizeAttribute in our ASP.NET Core applications.

public class Functions
  public async Task<IActionResult> GetRecord(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get")] HttpRequest req,
    ILogger log)
    var user = req.HttpContext.User;
    var record = GetUserData(user.Identity.Name);
    return new OkObjectResult(record);

  [FunctionAuthorize(Policy = "OnlyAdmins")]
  public async Task<IActionResult>(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get")] HttpRequest req,
    ILogger log)
    var records = GetAllData();
    return new OkObjectResult(records);
