javascript - Stripe 支付总是成功，paymentIntent 的金额不能更改

问题描述

我为在我的 Laravel 应用程序中实现 Stripe 苦苦挣扎了很长一段时间，但我遇到了很多问题。我确实以某种方式实现了逻辑，但我不能或者我不知道如何发送当前订单总额来创建 paymentIntent，所有付款都存储在控制器中设置的默认金额 500。我不得不提一下，在 stripe 的成功响应之后，当前订单应该存储在数据库中，其中包含在第一个表单中找到的用户运输详细信息，并且所有订购的产品都存储在会话中。让我给你一个更好的理解。

这是视图 (revieworder.blade.php)，其中我有 2 个表单，一个包含用户的运输详细信息，以及 Stripe 支付表单，以及会话中的购物车产品列表：

<ul class="list-group mb-3">
    <?php $total = 0 ?>
    @if(session('cart'))
        @foreach(session('cart') as $id => $details)
        <?php $total += $details['price'] * $details['quantity'] ?>
            <li class="list-group-item d-flex justify-content-between lh-condensed">
                <img src="../img/{{ $details['image'] }}" alt="{{ $details['name'] }}" width="60" height="60">
                <div>
                    <h6 class="my-0">{{ $details['name'] }}</h6>
                    <small class="text-muted">{{ __('Quantity') }}: {{ $details['quantity'] }}</small><br>
                    <small class="text-muted">{{ __('Unit price') }}: {{ $details['price'] }} RON</small>
                </div>
                <span class="text-muted">{{ $details['price'] * $details['quantity'] }} RON</span>
            </li>
        @endforeach
    @endif
    <li class="list-group-item d-flex justify-content-between">
        <span>Total (RON)</span>
        <strong id="total">{{ $total.' RON' }}</strong>
    </li>
</ul>


<form id="payment-form">
     @csrf
     <div id="card-element"><!--Stripe.js injects the Card Element--></div>
     <button id="submit" class="submit-id">
          <div class="spinner hidden" id="spinner"></div>
          <span id="button-text">Pay now</span>
      </button>
      <p id="card-error" role="alert"></p>
      <p class="result-message hidden">
      </p>
</form>

<script>
//Stripe script
var stripe = Stripe("pk_test_XXX");

// The items the customer wants to buy
var purchase = {
  items: [{id: "prod"}]   //sessions cart
};
console.log(purchase);

var elements = stripe.elements();

    var style = {
      base: { //some styling },
      invalid: {
        fontFamily: 'Arial, sans-serif',
        color: "#fa755a"
      }
    };

    var card = elements.create("card", { style: style });
    // Stripe injects an iframe into the DOM
    card.mount("#card-element");

    card.on("change", function (event) {
      // Disable the Pay button if there are no card details in the Element
      document.querySelector("button").disabled = event.empty;
      document.querySelector("#card-error").textContent = event.error ? event.error.message : "";
    });
// Disable the button until we have Stripe set up on the page
document.getElementsByClassName("submit-id").disabled = true;

$('#payment-form').submit(function(){
    fetch("{{ url(app()->getLocale().'/revieworder') }}", {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
        'X-CSRF-TOKEN': "{{ csrf_token() }}"
    },
    body: JSON.stringify(purchase)
    })
    .then(function(data) {
        $('#payment-form').submit(function(event) {
        event.preventDefault();
        // Complete payment when the submit button is clicked
        payWithCard(stripe, card, data.clientSecret);
        });
    });

    // Calls stripe.confirmCardPayment
    var payWithCard = function(stripe, card, clientSecret) {
    loading(true);
    stripe
        .confirmCardPayment(clientSecret, {
        payment_method: {
            card: card
        }
        })
        .then(function(result) {
        if (result.error) {
            // Show error to your customer
            showError(result.error.message);
        } else {
            // The payment succeeded!
            // The order should be stored in the database
            orderComplete(result.paymentIntent.id);
        }
        });
    };

    // Shows a success message when the payment is complete
    var orderComplete = function(paymentIntentId) {
    loading(false);
    document
        .querySelector(".result-message a")
        .setAttribute(
        "href",
        "https://dashboard.stripe.com/test/payments/" + paymentIntentId
        );
    document.querySelector(".result-message").classList.remove("hidden");
    document.getElementsByClassName("submit-id").disabled = true;
    };

    // Show the customer the error from Stripe if their card fails to charge
    var showError = function(errorMsgText) {
    loading(false);
    var errorMsg = document.querySelector("#card-error");
    errorMsg.textContent = errorMsgText;
    setTimeout(function() {
        errorMsg.textContent = "";
    }, 4000);
    };

    // Show a spinner on payment submission
    var loading = function(isLoading) {
    if (isLoading) {
        // Disable the button and show a spinner
        document.getElementsByClassName("submit-id").disabled = true;
        document.querySelector("#spinner").classList.remove("hidden");
        document.querySelector("#button-text").classList.add("hidden");
    } else {
        document.getElementsByClassName("submit-id").disabled = false;
        document.querySelector("#spinner").classList.add("hidden");
        document.querySelector("#button-text").classList.remove("hidden");
    }
    };
});

</script>

然后这是处理秘密客户端密钥和 paymentIntent (CheckoutController.php) 的控制器：

public function create(){
        \Stripe\Stripe::setApiKey('sk_test_XXX');  

        header('Content-Type: application/json');
        try {
            $json_str = file_get_contents('php://input');
            $json_obj = json_decode($json_str);
            
            $paymentIntent = \Stripe\PaymentIntent::create([
                'amount' => "500",
                'currency' => 'ron',
            ]);
            $output = [
                'clientSecret' => $paymentIntent->client_secret,
            ];
            echo json_encode($output);
        } catch (Error $e) {
            http_response_code(500);
            echo json_encode(['error' => $e->getMessage()]);
        }
    }

因此，其中一个问题是，每当我为订单付款时，无论我通过什么信用卡号，它总是成功，这是一个重大错误。第二个，我需要传递当前订单的总额，否则所有订单都会得到总额 500，默认值。我试图将会话购物车项目传递给 fetch，但它没有用。即使我无法将购物车中的所有物品都发送到意图，但至少总价格应该对应。

如果我对任何事情不够清楚，请告诉我。我真的很感激任何建议。谢谢！
