我的localhost项目网址是： middleware.dev 。首次登录此网址：

middleware.dev/login

，登录成功完成。然后输入此网址：

此页面无效

middleware.dev重定向了你太多次了。尝试清除你的   饼干。 ERR_TOO_MANY_REDIRECTS

Answer 1

这个问题很可能是由于重定向中出现了一个循环，就像你重定向到一个路由，这个路由将你重定向到形成一个循环的同一路径。

问题似乎与IsAdmin中间件中的逻辑有关。逻辑读取如果用户是管理员，则重定向到/admin，否则将请求传递到/admin路由。

这就是问题所在。例如，您点击middleware.dev/admin它将穿过IsAdmin中间件，并确认用户是管理员后会再次将其重定向到/admin路由，从而创建循环。

Answer 2

在IsAdmin.php类中尝试：

public function handle($request, Closure $next)
{
    $user = Auth::user();

    if(!$user->isAdmin()){
        return redirect('/');
    }

    return $next($request);
}

Answer 3

在IsAdmin中间件中尝试此操作

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;
use Route;

class IsAdmin
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

        $user =Auth::user();

        if ($user->isAdmin() && Route::currentRouteAction() != 'App\Http\Controllers\AdminController@index' ){

            return redirect()->intended('/admin');
        }

                return $next($request);



    }
}
