如何在 Laravel 中实现 Stripe 支付元素

How to implement Stripe Payment Element in Laravel

我正在尝试在 Laravel 中实施 Stripe 的新 Payment Element,它默认支持 Apple Pay、Google 支付和卡,并使用用户的国家 select 最相关的支付方式,但我可以在网上找到的所有将 Stripe 与 Laravel 集成的指南都使用旧的 Card 元素,或者甚至根本不使用 PaymentIntents API。

Stripe 的文档本身只涵盖了 PHP 实现,我无法从中弄清楚如何以 Laravel 惯用的方式实现它,目前这似乎是一种压倒性的方法任务。我将如何在 Laravel 中实施新的 Stripe 支付元素?

我终于成功了,作为一个解决方案,它足以让网站接受 one-time 付款,但如果您打算定期付款,我建议您冒险尝试并设置 Laravel jszobody.

我对 Stripe 文档中的代码进行了一些显着的更改,尽管除了这些更改之外,下面的代码几乎没有改动,并且肯定可以由在 [=] 方面更有经验的人以更 Laravel 的方式编写54=],我欢迎任何相应的编辑。


Routes/web.php:

Route::get('/payment', [PaymentController::class, "index"]);
Route::post('/charge', [PaymentController::class, "pay"]);

php artisan make:controller PaymentController创建引用控制器,并给PaymentController以下内容:

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Payment;
use Exception;
use Stripe;

class PaymentController extends Controller
{
 
    public function index()
    {
        return view('payment');
    }
 
    public function pay(Request $request)
    {

        // Replace with your secret key, found in your Stripe dashboard
        Stripe\Stripe::setApiKey('<YOUR_SECRET_KEY>'); 

        function calculateOrderAmount(array $items): int {
            return 499;
        }

        header('Content-Type: application/json');

        try {

            $jsonStr = file_get_contents('php://input');
            $jsonObj = json_decode($jsonStr);

            $paymentIntent = Stripe\PaymentIntent::create([
                'amount' => calculateOrderAmount($jsonObj->items),
                'currency' => 'gbp', // Replace with your country's primary currency
                'automatic_payment_methods' => [
                    'enabled' => true,
                ],
                // Remove if you don't want to send automatic email receipts after successful payment
                "receipt_email" => $request->email 
            ]);

            $output = [
                'clientSecret' => $paymentIntent->client_secret,
            ];

            echo json_encode($output);
        } catch (Exception $e) {
            return back()->with(['error' => $e->getMessage()]);
        }
    }
}

stripe_checkout.js:

与 Stripe 文档相比,此处最显着的变化是在 HTTP headers 中手动传递 CSRF 令牌。由于与 Laravel 的冲突,将此排除在外会导致 HTTP 419 错误,我花了比解决这个问题所花的时间长得多的时间。 提示:在调试此类内容时,有条不紊地解决您在浏览器控制台中看到的每个错误是让事情正常进行的关键。

// Replace with your public key, found in your Stripe dashboard
const stripe = Stripe("<YOUR_PUBLIC_KEY>");

            "X-CSRF-TOKEN": document.querySelector('input[name="_token"]').value,
        },
        body: JSON.stringify({ items }),
    }).then((r) => r.json());

    elements = stripe.elements({ clientSecret });

    const paymentElement = elements.create("payment");
    paymentElement.mount("#payment-element");

    e.preventDefault();

        },

        "payment_intent_client_secret"
    );

    if (!clientSecret) {
        return;
    }

    const { paymentIntent } = await stripe.retrievePaymentIntent(clientSecret);

    switch (paymentIntent.status) {
