如何正确使用付款意图，我不断收到错误无效的付款意图状态

Question

我正在尝试实现支付意图 api，但我一直收到无效的支付意图状态，我在 stack-overflow 上看到了一个答案，但它没有帮助， 我不知道它是一个糟糕的服务器端还是客户端实现，因为我还是新手

我尝试将 requires_action 更改为 requires_source_action，在收费下但没有任何帮助，尝试修改 html，但我不知道出了什么问题。

负责，我有

<?php
  # vendor using composer
  require_once('vendor/autoload.php');

  \Stripe\Stripe::setApiKey(getenv('sk_test_HERE'));

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

  # retrieve json from POST body
  $json_str = file_get_contents('php://input');
  $json_obj = json_decode($json_str);
  //$amount=$POST['amount'];
//----------------???? changed the intent from null;
  $intent = null;
  try {
    if (isset($json_obj->payment_method_id)) {
      # Create the PaymentIntent
      $intent = \Stripe\PaymentIntent::create([
        'payment_method' => $json_obj->payment_method_id,
        'amount' => 1000,
        'currency' => 'eur',
        'confirmation_method' => 'manual',
        'confirm' => true,
      ]);
    }
    if (isset($json_obj->payment_intent_id)) {
      $intent = \Stripe\PaymentIntent::retrieve(
        $json_obj->payment_intent_id
      );
      $intent->confirm();
    }
    generatePaymentResponse($intent);
  } catch (\Stripe\Error\Base $e) {
    # Display error on client
    echo json_encode([
      'error' => $e->getMessage()
    ]);
  }
//--------------------updated from requires action to requires source action
  function generatePaymentResponse($intent) {
    # Note that if your API version is before 2019-02-11, 'requires_action'
    # appears as 'requires_source_action'.
    if ($intent->status == 'requires_source_action' &&
        $intent->next_action->type == 'use_stripe_sdk') {
      # Tell the client to handle the action
      echo json_encode([
        'requires_action' => true,
        'payment_intent_client_secret' => $intent->client_secret
      ]);
    } else if ($intent->status == 'succeeded') {
      # The payment didn’t need any additional actions and completed!
      # Handle post-payment fulfillment
      echo json_encode([
        "success" => true
      ]);
    } else {
      # Invalid status
      http_response_code(500);
      echo json_encode(['error' => 'Invalid PaymentIntent status']);
    }
  }
?>

在我拥有的 JavaScript 文件中

// Create a Stripe client.
var stripe = Stripe('pk_test_HERE');

// Create an instance of Elements.
var elements = stripe.elements();

// Custom styling can be passed to options when creating an Element.
// (Note that this demo uses a wider set of styles than the guide below.)
var style = {
  base: {
    color: '#32325d',
    fontFamily: '"Helvetica Neue", Helvetica, sans-serif',
    fontSmoothing: 'antialiased',
    fontSize: '16px',
    '::placeholder': {
      color: '#aab7c4'
    }
  },
  invalid: {
    color: '#fa755a',
    iconColor: '#fa755a'
  }
};

// Create an instance of the card Element.
var card = elements.create('card', {style: style});

// Add an instance of the card Element into the `card-element` <div>.
//                                     added an extra s for form control
card.mount('#card-elements');

// Handle real-time validation errors from the card Element.
card.addEventListener('change', function(event) {
  var displayError = document.getElementById('card-errors');
  if (event.error) {
    displayError.textContent = event.error.message;
  } else {
    displayError.textContent = '';
  }
});

// Handle form submission.
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
  event.preventDefault();

  stripe.createToken(card).then(function(result) {
    if (result.error) {
      // Inform the user if there was an error.
      var errorElement = document.getElementById('card-errors');
      errorElement.textContent = result.error.message;
    } else {
      // Send the token to your server.
      stripeTokenHandler(result.token);
    }
  });
});

// Submit the form with the token ID.
function stripeTokenHandler(token) {
  // Insert the token ID into the form so it gets submitted to the server
  var form = document.getElementById('payment-form');
  var hiddenInput = document.createElement('input');
  hiddenInput.setAttribute('type', 'hidden');
  hiddenInput.setAttribute('name', 'stripeToken');
  hiddenInput.setAttribute('value', token.id);
  form.appendChild(hiddenInput);

  // Submit the form
  form.submit();
}

我不断收到错误消息：付款意图状态无效

Answer 1

看起来您可能正在处理较旧的文档。您收到“无效的付款意图状态”，因为您的代码正在寻找不存在的状态 requires_source_action：https://stripe.com/docs/payments/intents#intent-statuses

实际状态可能是requires_confirmation，在这种情况下，您必须确认服务器上的 PaymentIntent。然后根据状态，您可以得到requires_action 状态或succeeded。您获得哪一个取决于相关卡是否需要 3DS。

由于您的 PaymentIntent 使用的是手动确认流程，这意味着您必须在前端和后端之间进行多次往返，才能真正完成付款。我建议考虑改用自动确认。这样你只有两个步骤：

1. 在服务器上创建 PaymentIntent，将客户端密钥 ID 传递给前端
2. 像现在一样使用 Elements 收集付款详细信息，使用步骤 1 中的客户端密码和 Stripe.js 的handleCardPayment 完成付款

在此处了解有关该流程的更多信息：https://stripe.com/docs/payments/payment-intents/quickstart#automatic-confirmation-flow

除非您有充分的理由使用手动确认，否则我会坚持使用自动确认。
