Laravel如何集成Stripe或PayPal进行支付处理

use Stripe\Stripe;
use Stripe\Checkout\Session;

public function createCheckoutSession()
{
    Stripe::setApiKey(config('services.stripe.secret'));

    $session = Session::create([
        'payment_method_types' => ['card'],
        'line_items' => [[
            'price_data' => [
                'currency' => 'usd',
                'product_data' => [
                    'name' => '商品名称',
                ],
                'unit_amount' => 1000, // 金额，单位为分
            ],
            'quantity' => 1,
        ]],
        'mode' => 'payment',
        'success_url' => route('payment.success'),
        'cancel_url' => route('payment.cancel'),
    ]);

    return response()->json(['id' => $session->id]);
}

use Srmklive\PayPal\Services\ExpressCheckout;

class PayPalController extends Controller
{
    public function pay()
    {
        $provider = new ExpressCheckout();

        $data = [];
        $data['items'] = [
            [
                'name' => '商品名称',
                'price' => 10.00,
                'qty' => 1
            ]
        ];
        $data['return_url'] = route('paypal.success');
        $data['cancel_url'] = route('paypal.cancel');
        $data['invoice_id'] = uniqid();
        $data['invoice_description'] = "订单描述";
        $data['total'] = 10.00;

        $response = $provider->setExpressCheckout($data);
        return redirect($response['paypal_link']);
    }

    public function success()
    {
        // 处理成功回调
    }

    public function cancel()
    {
        // 用户取消支付
    }
}
