使用 Stripe 和 ASP.NET Core 向现有客户收费
Charge an existing customer with Stripe and ASP.NET Core
这是我使用条纹支付的自定义表单集成的工作代码。
问题是：如何处理回头客？我正在存储他们第一次 purchase.The 下次客户结账时的客户 ID，我不希望他们重新输入信用卡信息。
我可以找到很多关于如何使用费用 API 执行此操作的示例，但现在他们鼓励使用 PaymentIntents API。
自定义表单：

回答我自己的问题：
在创建 Stripe 客户时，将 paymentMethodId 附加到它。
var paymentMethodAttachOptions = new PaymentMethodAttachOptions { 客户
= customer.Id };
var paymentMethodService = new PaymentMethodService();
paymentMethodService.Attach(paymentMethodId, paymentMethodAttachOptions);
下次付款，在服务器端，获取客户paymentMethods
var 选项 = 新的 PaymentMethodListOptions
{
客户 = user.StripeCustomerId,
类型 = "卡片",
};
var service = new PaymentMethodService();
StripeList paymentmethods = await service.ListAsync(options);
在服务器上，向客户收费
var paymentIntentCreateOptions = new PaymentIntentCreateOptions
{
说明 = "...",
PaymentMethod = paymentmethods.First().Id,
客户 = user.StripeCustomerId,
收据邮箱 = user.Email,
数量 = 5500,
货币 = "欧元",
确认=真，
ConfirmationMethod = "manual",
};
