.net core api 5.0 null HttpContext Identity User Name-CodePudding

I have been searching here on who else has this issue with getting the User info from HttpContextAccessor.HttpContext.User.Identiy.Name

but it is always null.

I am using .net api core v5 and in my startup.cs

public void ConfigureServices(IServiceCollection services)
{
  services.AddHttpContextAccessor();
  ...
  services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
  app.UseRouting();

  app.UseCors(AllowedOrigins);
  app.UseAuthentication();
  app.UseAuthorization();
  app.UseEndpoints(endpoints =>
  {
    endpoints.MapControllers();
  });
}

In my visual studio launchSettings.json

{
  "iisSettings": {
    "windowsAuthentication": true,
    "anonymousAuthentication": true, // also turned it to false to test
    "iisExpress": {
      "applicationUrl": "http://localhost:55555/",
      "sslPort": 44444
    }
  },

  ...
}

Here is my Controller with test code to get the user info

public class MyController : ControllerBase
    {
 
        private readonly IHttpContextAccessor httpContextAccessor;
        public MyController (IHttpContextAccessor _httpContextAccessor)
        {
            httpContextAccessor = _httpContextAccessor;
        }

        [HttpGet]
        public async Task<ActionResult<ReturnDto>> GetTestData()
        {
            string userName = httpContextAccessor.HttpContext.User.Identity.Name;

            // also try to get user from ControllerBase  
            var ControllerBaseName = this.User;
            Both of these test result are null.
            return Ok();
        }

    }

I cannot figure out why the HttpContext user is always null. I read a few post here but my startup.cs is the same. Another user said try ControllerBase.User but that is null too. I am testing this with my Visual Studio debugger

Is there another easier way to get the logged in userID?

Any help is appreciated. Thanks

CodePudding user response：

Are you configuring the authentication service to use Windows Auth?

services.AddAuthentication(IISDefaults.AuthenticationScheme);

more info here: https://docs.microsoft.com/en-us/aspnet/core/security/authentication/windowsauth?view=aspnetcore-5.0

CodePudding user response：

Figured it out, web.config authenication settings to get HttpContext user name to show

        <authentication>
            <anonymousAuthentication enabled="false" />
            <windowsAuthentication enabled="true" />
        </authentication>
