如何在Laravel收银台使用其他支付网关？

'aliPay' => [
    'driver' => 'omnipay',
    'options' => [
        'gateway' => 'Alipay_AopPage',
        'options' => [
            'app_id' => 'your_app_id',
            'private_key' => 'your_private_key',
            'public_key' => 'your_public_key',
            'return_url' => 'your_return_url',
            'notify_url' => 'your_notify_url',
        ],
    ],
],

use Omnipay\Omnipay;

class PaymentController extends Controller
{
    public function pay()
    {
        $gateway = Omnipay::create('AliPay');
        $gateway->initialize(config('services.aliPay.options'));

        // 设置支付参数
        $params = [
            'out_trade_no' => 'your_order_number',
            'subject' => 'your_order_subject',
            'total_amount' => 'your_order_amount',
        ];

        // 发起支付请求
        $response = $gateway->purchase($params)->send();

        // 处理支付响应
        if ($response->isRedirect()) {
            // 重定向到支付页面
            $response->redirect();
        } else {
            // 支付失败处理
            echo $response->getMessage();
        }
    }
}

<form action="{{ route('payment.pay') }}" method="POST">
    @csrf
    <button type="submit">支付宝支付</button>
</form>
