javascript - Stripe 支付表格不适用于 Django，无法检索 token

Question

我想在我的网站上添加一个支付页面，我从 stripe 文档中复制了代码，但是当我按下支付按钮时没有任何反应。经调试，返回的token为空。问题是，当我在 JsFiddle 中尝试代码时，它起作用了，但是当我将它添加到我的应用程序时，没有任何响应，控制台是空的，所以我迷失了故障排除。这是 html 文件:

{% block content %}
<form   method="POST" id="payment-form" >
{% csrf_token %}
  <input type="hidden" name="token" />
    <div class="group">
      <label>
        <span>Card</span>
        <div id="card-element" class="field"></div>
          <div id="card-errors" role="alert"></div>
      </label>
    </div>
    <div class="group">
      <label>
        <span>Name</span>
        <input id="name" name="name" class="field" placeholder="Jane Doe" />
      </label>
    </div>
    <div class="group">
      <label>
        <span>Address</span>
        <input id="address-line1" name="address_line1" class="field" placeholder="77 Winchester Lane" />
      </label>
      <label>
        <span>Address (cont.)</span>
        <input id="address-line2" name="address_line2" class="field" placeholder="" />
      </label>
      <label>
        <span>City</span>
        <input id="address-city" name="address_city" class="field" placeholder="Coachella" />
      </label>
      <label>
        <span>State</span>
        <input id="address-state" name="address_state" class="field" placeholder="CA" />
      </label>
      <label>
        <span>ZIP</span>
        <input id="address-zip" name="address_zip" class="field" placeholder="92236" />
      </label>
      <label>
        <span>Country</span>
        <input id="address-country" name="address_country" class="field" placeholder="United States" />
      </label>
    </div>
    <button type="submit">Pay $25</button>
    <div class="outcome">
      <div class="error"></div>
      <div class="success">
        Success! Your Stripe token is <span class="token"></span>
      </div>
    </div>
  </form>




{% endblock %}

{% block body_scripts %}
<script >
var stripe = Stripe('stripeKeyGoesHere');
var elements = stripe.elements();

var card = elements.create('card', {
  hidePostalCode: true,
  style: {
    base: {
      iconColor: '#666EE8',
      color: '#31325F',
      lineHeight: '40px',
      fontWeight: 300,
      fontFamily: 'Helvetica Neue',
      fontSize: '15px',

      '::placeholder': {
        color: '#CFD7E0',
      },
    },
  }
});
card.mount('#card-element');

function setOutcome(result) {
  var successElement = document.querySelector('.success');
  var errorElement = document.querySelector('.error');
  successElement.classList.remove('visible');
  errorElement.classList.remove('visible');
console.log(result);
  if (result.token) {
    // In this example, we're simply displaying the token
    successElement.querySelector('.token').textContent = result.token.id;
    successElement.classList.add('visible');

    // In a real integration, you'd submit the form with the token to your backend server
    var form = document.querySelector('form');
    form.querySelector('input[name="token"]').setAttribute('value', result.token.id);
    form.submit();
  } else if (result.error) {
    errorElement.textContent = result.error.message;
    errorElement.classList.add('visible');
  }
}

card.on('change', function(event) {
  setOutcome(event);
});

document.querySelector('form').addEventListener('submit', function(e) {
  e.preventDefault();
  var options = {
    name: document.getElementById('name').value,
    address_line1: document.getElementById('address-line1').value,
    address_line2: document.getElementById('address-line2').value,
    address_city: document.getElementById('address-city').value,
    address_state: document.getElementById('address-state').value,
    address_zip: document.getElementById('address-zip').value,
    address_country: document.getElementById('address-country').value,
  };
  stripe.createToken(card, options).then(setOutcome);
});

</script>

这是 View :

def payments(request):
    if request.user.profile.is_seller is False:
        key = settings.STRIPE_PUBLIC_KEY
        if request.method == 'POST':
            stripe.api_key = settings.STRIPE_SECRET_KEY
            #form = CreateCustomer(request.POST)
            token = request.POST.get('token')
            print(token)
            #if form.is_valid():
                #something
            return render(request, 'payment_card.html', {'key': key})
        else:
            print('it is a get')
            return render(request, 'payment_card.html', {'key':key})

    else:
        raise PermissionDenied

当您说单击按钮时没有任何反应时，您能否在调试时(使用浏览器开发工具？)看到表单提交是否真的发生了？

此外，您能否尝试在 if (result.token) { } 之前的 setOutcome 函数中添加一个 console.log(result) ?

当您调试服务器端代码时，您能否看到您的 Controller / View /处理程序，即 payments(request) 在提交表单时被调用？你能查一下request.POST字典的内容吗？

这个想法是检查当您提交表单时是否真的发出了 POST 请求(客户端使用浏览器开发工具)，以及您的服务器端 Controller 是否确实接收/处理了请求以及接收到的 POST 请求看起来如何(特别是 request.POST 字典)。
