How to get logged in user identity details in ASP.NET Web API controller
From the ASP.NET Web API controller use the User.Identity object to retrieve user details

User.Identity.IsAuthenticated - Returns true or false depending on whether the user is authenticated
User.Identity.AuthenticationType - Authentication Type used
User.Identity.Name - Logged in username

RequestContext.Principal.Identity.IsAuthenticated - Returns true or false depending on whether the user is authenticated
RequestContext.Principal.Identity.AuthenticationType - Authentication Type used
RequestContext.Principal.Identity.Name - Logged in username

Instead of using User.Identity, we can also use RequestContext.Principal.Identity

Now let us see what these properties return if we are not logged in.
1. Add a new Empty Web API 2 Controller to the EmployeeService project. Name it TestController.
2. Copy and paste the following code in TestController.

using System.Web.Http;
namespace EmployeeService.Controllers
{
public class TestController : ApiController
{
public string Get()
{
return "Hello from TestController";
}
}
}

3. Set a breakpoint on the Get() method in TestController. Run the application in Debug mode and navigate to /api/Test. When the execution pauses at the breakpoint, open Immediate Window and type the above properties one by one and press enter.

Since we are not logged in, notice IsAuthenticated property returns false. Since we are not authenticated AuthenticationType and Name properties return NULL.

[ramchandrathakkar]

cool...But i have two doubts,

1. if any third party is accessing our web API then how can we come to know identity??

2.instead of Microsoft inbuilt auto generated identity table can we used our own created table for authorization??

thanking you

Thank you so much for this tutorial, it really helps, I have learned a lot.

By the way, can you make a tutorial for ASP.NET core? I have a lot of problem with it, especically about Identity.

[feelgoodcontent]

Is this secured? because we are storing data in browser, what if the hacker tries to break the application?
