如何防止两个 Laravel 中间件创建无休止的重定向？

Question

我有两个不是路由中间件的中间件。它们专门用于确保为登录用户准备好两件事。已签署付款和文件。

我的kernel.php:

    protected $middleware = [
    'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
    'Illuminate\Cookie\Middleware\EncryptCookies',
    'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
    'Illuminate\Session\Middleware\StartSession',
    'Illuminate\View\Middleware\ShareErrorsFromSession',
    'App\Http\Middleware\VerifyCsrfToken',
    'App\Http\Middleware\AuthenticateSigned',
    'App\Http\Middleware\FeesOwed',
    'App\Http\Middleware\DeniedAccess'
];

造成此问题的是 AuthenticateSigned 和 FeesOwed

第一个AuthenticateSigned：

public function handle($request, Closure $next)
{
    if ($this->auth->guest())
    {
        if ($request->ajax()){
            return response('Unauthorized.', 401);
        } else {
            return redirect()->guest('login');
        }

    } else if(!$this->auth->user()->role->administrator){ // the users not an admin

        if(!$this->auth->user()->agreement_id || $this->auth->user()->signed_current_membership_agmt == 0 ){
            if ($request->ajax()){
                return response('Unauthorized.', 401);
            } else {
                return redirect()->route('agreement');
            }
        }

        return $next($request);

    } 

    return $next($request);

}

然后我欠费：

public function handle($request, Closure $next)
{

    $uri = $request->server()['REQUEST_URI'];

    if($this->auth->user() 
        && $this->auth->user()->role_id != 3
        && $this->auth->user()->unpaidFees() // Does the user have past due fees
        && $uri != '/profile/investment-fees' // view of form to pay fees
        && $uri != '/profile/charge-investment-fees' // post request to pay fees
        && $uri != '/profile/pay-payment'

        && $uri != '/logout'
        //&& !$this->auth->user()->role->administrator // admins shouldn't be subject to this
        ){
        \Session::flash('message','You must pay past due management fees before using the rest of the members platform.');

        return redirect()->route('profile.investment-fees');
    } 

    return $next($request);
}

我已经阅读了大量的 SO 帖子和 laracast，所有的注释要么是 "your missing a return $next($request);"，要么是路由中间件。

一直使用这些中间件运行，因为有时候让用户知道他们需要签署新协议或支付费用很重要。

非常感谢任何帮助。谢谢

当来宾用户尝试访问 /login 时，AuthenticateSigned 中间件会将其重定向到 /login，从而导致无限重定向循环。

当请求的 URL 与您尝试重定向的目标相同时避免重定向。
