Slim 3中间件重定向 [英] Slim 3 Middleware Redirect

问题描述

我想检查用户是否已登录.因此，我有一个Class witch返回true或false.现在，我需要一个可检查用户是否已登录的中间件.

I want to check if a user is logged in. Therefor I have an Class witch returns true or false. Now I want a middleware which checks if the user is logged in.

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

身份验证类

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，当不强制用户时，我想重定向到主页.但是如何?！

So when the user is logged in the page will render correctly. But when the user is not autoriesed I want to redirect to the homepage. But how?!

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

这不起作用！

推荐答案

您需要return响应.不要忘记request和response对象是不可变的.

You need to return the response. Don't forget that the request and response objects are immutable.

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

我有一个类似的身份验证中间件，这就是我做的方法，它还添加了403(未授权)标头.

I have a similar auth middleware and this is how I do it which also adds a 403 (unauthorized) header.

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