Get the user id logged in

I'm doing user management where any user can disable any user. But, the logged-in user can not deactivate.

How do I get the id of the logged-in user?

component.ts:

export class AUsuariosComponent {

  model: any = {};
  userObj: User;
  users: User;
  users2: User;

  constructor(private userService: UserService, private router: Router) { }

  register() {
    this.users2 = new User();
    this.users2.email = this.users.email;
    this.users2.password = this.users.password;
    this.users2.user = this.users.user;
    this.userService.create(this.users2).subscribe(
      data => {
        this.refresh()
      },
      error => {
        console.log(Error)
      }
    )
  }

  refresh(): void {
    window.location.reload();
  }

  ngOnInit() {
    this.userService.getUsers().subscribe(
      response => {
        if (!response) {
          console.log(Error)
        } else {
          console.log(response)
          this.users = response
        }
      })
  }

  getUser(user: User) {
    this.userObj = user;
    this.userService.getUserById(user.id).subscribe(
      response => {
        if (!response) {
          console.log(Error)
        } else {
          this.users = response
        }
      })
  }

  updateUser(user: User) {
     this.userService.update(user).subscribe(
      data => {
        this.refresh()
      },
      error => {
        console.log(Error)
      }) 
  }

  desativarUsuario(user: User) {
    this.getUser(user);

    if (user.active == true){
      user.active = false;
      this.userService.update(user).subscribe(
        data => {
          this.refresh()
        },
        error => {
          console.log(Error)
        }) 
    } else if (user.active == false) {
      user.active = true;
      this.userService.update(user).subscribe(
        data => {
          this.refresh()
        },
        error => {
          console.log(Error)
        }) 
    }
  }

}
