用于订单信息的laravel中的自定义中间件

php artisan make:middleware CustomMiddleware

<?php

namespace App\Http\Middleware;

use Closure;

class CustomMiddleware
{
    public function handle($request, Closure $next)
    {
        // 检查订单信息是否有效
        $order = $request->input('order');
        if (!$this->isValidOrder($order)) {
            return response('Invalid order', 400);
        }

        return $next($request);
    }

    private function isValidOrder($order)
    {
        // 在这里编写订单信息验证的逻辑
        // 返回true表示订单有效，返回false表示订单无效
    }
}

protected $routeMiddleware = [
    // 其他中间件...
    'custom' => \App\Http\Middleware\CustomMiddleware::class,
];

Route::get('/order', function () {
    // 在这里处理订单信息
})->middleware('custom');

class OrderController extends Controller
{
    public function __construct()
    {
        $this->middleware('custom');
    }

    // 其他方法...
}
