如何有条件地允许导航到用户

Question

所以这是我的问题，我想在我的代码中测试这个canActivate 函数。

我的 AuthRoleGuardService.ts 文件：

export class AuthRoleGuardService implements CanActivate {
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    const currentUser = this.authService.currentUserSubject.value;

    if (Roles[currentUser.role] >= route.data.role) {
      return true;
    }

    this.router.navigate(['/access-denied'], { queryParams: { redirect: state.url }, replaceUrl: true });
    return false;
  }
}

这是我迄今为止尝试过的：

  it('should allow navigation if user has minimum role', () => {});

  it('should not allow navigation if user does not have minimum role', () => {
    const role = 'DISPLAY';
    const routerMock = jasmine.createSpyObj('Router', ['navigate']);
    expect(roleGuard.canActivate(undefined, ({ url: 'users' } as any) as RouterStateSnapshot)).toBe(false);
    expect(routerMock.navigate).toHaveBeenCalledWith(['access-denied']);
  });

如何传递角色？

也许是一个很好的解决方案：

  it('should not allow navigation if user does not have minimum role', fakeAsync(() => {
    user.role = 'DISPLAY';

    const route = new ActivatedRouteSnapshot();

    route.data = { role: Roles.SHIFTLEAD };

    expect(roleGuard.canActivate(route, mockStateSnapshot)).toBe(false);
    expect(mockRouter.navigate).toHaveBeenCalledWith(['/access-denied'], {
      queryParams: { redirect: undefined },
      replaceUrl: true
    });
  }));

要测试守卫，您必须执行以下操作：

{ path : "", component : ComponentName, canActivate : [GuardName]}

案例一：

export class AuthRoleGuardService implements CanActivate {
  test : number = 0 ;
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {

    if (this.test != 0) {
      return true;
    }

    this.router.navigate('/access-denied');
    return false;
  }
}

对于这种情况，用户将停留在他所在的页面中，因为我无法访问目标页面

案例 2：

export class AuthRoleGuardService implements CanActivate {
  test : number = 0 ;
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {

    if (this.test == 0) {
      return true;
    }

    this.router.navigate('/access-denied');
    return false;
  }
}

在这种情况下，用户将转到目标页面，因为 test 的值等于 '0'
