使用 Stripe 和 Python-Flask 订阅的示例？

Question

我试图找出使用 Stripe 于 2019 年 7 月 1 日提供的新工具集编写简单订阅的方法（请参阅此处https://stripe.com/docs/payments/checkout/fulfillment）以满足 SCA 规定，但它对我不起作用。如果有人可以在 Flask/Python 中分享一个完整的示例（结帐、查看等），那就太好了。

我附上了我在使用 Stripe 仪表板创建产品和计划后实现的代码。我的客户将来自我的代码/数据库，这是我尚未真正开发的东西。

视图.py

@app.route('/checkout', methods=['GET', 'POST'])
def checkout():
    session = stripe.checkout.Session.create(
      payment_method_types=['card'],
      subscription_data={
        'items': [{
          'plan': 'my_plan_id',
        }],
      },
      success_url='https://mywebsite.com',
      cancel_url='https://mywebsite.com',
    )

    print(session)

    return render_template('/web/premium/checkout.html')

checkout.html 是

<script src="https://js.stripe.com/v3/"></script>

<script>
var stripe = Stripe('pk_test_jOuM3bOylIuDHhxMk19ut3CH');

stripe.redirectToCheckout({
  items: [
    {sku: 'my_product_id', quantity: 1}
  ],
  successUrl: 'https://mywebsite.com',
  cancelUrl: 'https://mywebsite.com',
  submitType: 'donate',
}).then(function (result) {
});


</script>

这是我打印“会话”时得到的：
