我使用Django/Stripe SDK创建了一个Stripe订阅，由于软件位于欧洲，所以使用了新的SCA（Strong Customer Authentication）。首先我将来源附加到客户端，然后尝试为他们订阅，虽然可以工作，但对于某些客户，在Stripe控制面板上看到了重复的付款。
我已经联系了Stripe，他们的客户支持建议如下，但我无法解决：
"I see what you mean when you say the customers are being charged more than once. The issue boils down to the API call requesting them to be added to a subscription is being sent more than once to Stripe from your server.
To solve this on your end, you will need to make sure your system is sending a request only once. I would recommend checking your server to see where the requests are coming from. It may be an easy solve on that end once this is determined."
