Laravel 9 限制IP登入

之前被要求要做到的功能，後面又棄用了
routes：

<?php
use Illuminate\Support\Facades\Route;
//限制Admin登入時要符合IP
Route::middleware('limitAdminLoginIP')->group(function () {
	//Admin login
	Route::post('/login', [\App\Http\Controllers\v1\admin\UserController::class, 'login']);
});

app/Http/Kernel.php

<?php

namespace App\Http;

use App\Http\Middleware\LimitAdminLoginIP;
use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
    /**
     * The application's global HTTP middleware stack.
     *
     * These middleware are run during every request to your application.
     *
     * @var array
     */
    protected $middleware = [
        // \App\Http\Middleware\TrustHosts::class,
        \App\Http\Middleware\TrustProxies::class,
        \Illuminate\Http\Middleware\HandleCors::class,

    ];

    /**

     *
     * @var array>
     */
    protected $middlewareGroups = [
        'api' => [

        ],
    ];

    /**
     * The application's route middleware.
     *
     * These middleware may be assigned to groups or used individually.
     *
     * @var array
     */
    protected $routeMiddleware = [

        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

        'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
        'limitAdminLoginIP' => LimitAdminLoginIP::class,
    ];
}

Middleware：

<?php
namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Illuminate\Http\JsonResponse;

/**
 * 限制Admin在操作API時如果
 * IP不被允許則直接回傳錯誤
 */

     * Construct
     */
    public function __construct()
    {
    }

     *

     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
     */
    public function handle(Request $request, Closure $next)
    {
        $lang = trim($request->header('lang'));
        //取得遠端IP
        $ip = $request->header('X-FORWARDED-FOR');
        //需要過濾DNS proxy問題所以前面那組IP才是使用者真實IP
        if (stripos($ip, ", ") !== false) {
            $ipAddresses = explode(", ", $ip);
            $ip = $ipAddresses[0];
        }

        //允許登入IP
        $allowIP = ["192.168.1.1", "192.168.10.1"]
        $allowIP = explode(",", $allowIP);
        //檢查IP是否存在於其中之一
        if (!IpUtils::checkIp($ip, $allowIP)) {
      		response()->json([
                'msg' => 'test',
                'errno' => 1000,
            ]);
        }

        return $next($request);
    }
}
