超薄3中间件重定向

Question

我想检查用户是否已登录.因此我有一个类巫婆返回true或false.现在我想要一个中间件来检查用户是否已登录.

$app->get('/login', '\Controller\AccountController:loginGet')->add(Auth::class)->setName('login');
$app->post('/login', '\Controller\AccountController:loginPost')->add(Auth::class);

Auth Class

class Auth {
    protected $ci;
    private $account;

    //Constructor
    public function __construct(ContainerInterface $ci) {
        $this->ci = $ci;
        $this->account = new \Account($this->ci);
    }

    public function __invoke($request, \Slim\Http\Response $response, $next) {
        if($this->account->login_check()) {
            $response = $next($request, $response);
            return $response;
        } else {
            //Redirect to Homepage
        }

    }
}

因此,当用户登录时,页面将正确呈现.但是当用户未自动生成时,我想重定向到主页.但是如何？!

$response->withRedirect($router->pathFor('home');

这不起作用!

你需要return回复.不要忘记request和response对象是不可变的.

return $response = $response->withRedirect(...);

我有一个类似的auth中间件,这就是我这样做,它还添加了403(未授权)标头.

$uri = $request->getUri()->withPath($this->router->pathFor('home'));
return $response = $response->withRedirect($uri, 403);
