用例:我想将登录用户重定向到/dashboard,将未登录用户重定向到/landing。
初拍:
{
path: '**',
redirectTo: '/dashboard',
canActivate: [AuthGuard],
},
{
path: '**',
redirectTo: '/landing'
}
@Injectable({
providedIn: 'root'
})
export class AuthGuard implements CanActivate {
constructor(private auth: AuthService, private router: Router) {}
canActivate(next: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean|UrlTree> | Promise<boolean|UrlTree> | boolean | UrlTree {
return this.auth.isAuthenticated$
}
}
所有用户都被重定向到仪表板页面。
第二次尝试:
{
path: '**',
redirectTo: '/home/loggedin',
canActivate: [AuthGuard],
data: { authGuard: { redirect: '/home/loggedout' } }
},
{
path: '**',
redirectTo: '/home/loggedin'
}
@Injectable({
providedIn: 'root'
})
export class AuthGuard implements CanActivate {
constructor(private auth: AuthService, private router: Router) {}
canActivate(
next: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean|UrlTree> | Promise<boolean|UrlTree> | boolean | UrlTree {
return this.auth.isAuthenticated$.pipe(
map(loggedIn => {
console.log(`A=${loggedIn} ${JSON.stringify(next.data.authGuard.redirect)}`)
if (!loggedIn && next.data.authGuard.redirect) {
return this.router.parseUrl(next.data.authGuard.redirect);
} else {
return false;
}
})
);
}
}
似乎甚至没有调用 AuthGuard。可能如果我使用组件而不是重定向?
{
path: '**',
component: RedirectingComponent,
canActivate: [AuthGuard],
data: { authGuard: { redirect: '/home/loggedout' }, redirectComponent: { redirect: '/home/loggedin' } }
}
现在这似乎可行,但它也是一个糟糕的 hack。
如何使 AuthGuards 与重定向一起工作?
你的
AuthGuard
可以强制导航。在您的第一次尝试中,将守卫更改为这样的东西:
@Injectable({
providedIn: 'root'
})
export class AuthGuard implements CanActivate {
constructor(private auth: AuthService, private router: Router) {}
canActivate(next: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean|UrlTree> | Promise<boolean|UrlTree> | boolean | UrlTree {
// if user is authenticated just return true;
if (this.auth.isAuthenticated$) { return true; }
// if user is not authenticated redirect the user and return false
this.router.navigate(['/landing']);
return false;
}
}
这应该将未经身份验证的用户重定向到登录页面。您还可以在角度文档here.
中查看示例您可以使用
children: []
而不是设置 component
(像这样)
{
path: '',
canActivate: [AuthGuard],
children: []
}
