Laravel 5.6中RedirectIfAuthenticated的逻辑是什么？

Question

我有3个用户，“ admin”，“ mahasiswa”和“ dosen”（不同的表）。我想，例如，如果用户“ admin”已登录访问主链接（例如：localhost），然后重定向到localhost / admin / home。现在，当用户登录并访问主页（localhost）时，将再次显示登录表单。谢谢

此RedirectIfAuthenticated：

<?php

namespace App\Http\Middleware;

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

class RedirectIfAuthenticated
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string|null  $guard
     * @return mixed
     */
    public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->check()) {
            return redirect('/home');
        }

        return $next($request);
    }
}

这是Auth.PHP

'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
        'mahasiswa' => [
            'driver' => 'session',
            'provider' => 'mahasiswa',
        ],
        'dosen' => [
            'driver' => 'session',
            'provider' => 'dosen',
        ],
    ],

    

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],

        'mahasiswa' => [
            'driver' => 'eloquent',
            'model' => App\Mahasiswa::class,
        ],
        'dosen' => [
            'driver' => 'eloquent',
            'model' => App\Dosen::class,
        ],
    ],

您可以根据中间件$guard在中间件中进行检查，可以执行以下操作：

    public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->check()) {
            if($guard == 'mahasiswa')
                return redirect('/mahasiswa/home');
            elseif($guard == 'dosen')
                return redirect('/dosen/home');
            elseif($guard == 'web')
                return redirect('/admin/home');
            else
                return redirect('/home');
        }

        return $next($request);
    }
