我已经使用Django / Stripe SDK创建了条带订阅，并且由于该软件在欧洲，所以它使用了新的SCA（严格的客户身份验证）。因此，首先我将源附加到客户，然后尝试订阅他们，它可以工作，但是对于某些客户，我在Stripe控制面板上看到重复付款。
我已经联系了Stripe，他们的客户支持建议了以下内容，但我不明白：
当您说向客户收取的费用超过
时，我明白您的意思了 一旦。问题归结为API调用，要求将它们添加到 订阅已从您的服务器多次发送到Stripe。要最终解决此问题，您需要确保系统正在发送 一个请求一次。我建议检查您的服务器以查看 请求来自。为此，这可能是一个简单的解决方案 确定。

我通过在用户订阅前检查用户是否有当前有效的订阅来解决此问题，我不确定为什么会首先发生这种情况，但我想这是由于互联网速度或移动设备断开连接造成的，因此javascript正在发送请求，但在重定向用户之前，它将失去连接。
这是我使用Stripe SDK修复它的方法：
customer = stripe.Customer.retrieve(user_membership.stripe_customer_id)
if customer.subscriptions.total_count > 0:
for i in customer.subscriptions.data:
if i.plan['id'] == selected_membership.stripe_plan_id and i.plan['active'] == True:
messages.info(
request, "Your have already subscribed to this plan")
return redirect(reverse('membership:update-transactions',
kwargs={
'subscription_id': i.id
}))
else:
pass # Maybe we can check if users have a subscription that needs renewing
else:
如果有人有更干净的代码，请与我分享。 ?
