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）。我想要例如用户“admin”已经登录访问主链接（例如：localhost），然后重定向到 localhost/admin/home。现在，当用户登录并访问主页（本地主机）时，将再次显示登录表单。谢谢

这个 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 $guard 对中间件进行检查，您可以执行以下操作：

    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);
    }
