[Authorize(AuthenticationSchemes = "Windows")]
[Route("api/[controller]")]
[ApiController]
public class UserController : ControllerBase
{
    [HttpGet("username")]
    public IActionResult GetUsername()
    {
        var username = User.Identity.Name;
        return Ok(username);
    }
}

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class WindowsAuthService {
  private apiUrl = 'https://your-api-url/api/user/username';

  constructor(private http: HttpClient) { }

  getUsername() {
    return this.http.get<string>(this.apiUrl);
  }
}

import { Component } from '@angular/core';
import { WindowsAuthService } from './windows-auth.service';

@Component({
  selector: 'app-root',
  template: `
    <div *ngIf="username">
      Windows用户名：{{ username }}
    </div>
  `
})
export class AppComponent {
  username: string;

  constructor(private windowsAuthService: WindowsAuthService) { }

  ngOnInit() {
    this.windowsAuthService.getUsername().subscribe(
      username => this.username = username,
      error => console.error(error)
    );
  }
}
