如何在Stripe中指定订阅时长并关联Subscription Schedule避免重复订阅

你当前的代码逻辑存在两个独立的订阅创建流程，因此会生成重复订阅：

• 提前调用stripe.subscriptionSchedules.create创建了绑定目标客户的24个月订阅计划，该计划本身会对应生成一个订阅
• 后续创建的mode: 'subscription'类型Checkout会话，付款成功后默认会生成一个全新的独立订阅

推荐直接在创建Checkout会话时传入订阅计划配置，无需提前单独创建Subscription Schedule，避免重复生成订阅：

修正后代码示例 #

const customer = await stripe.customers.create({
  description: "My First Test Customer (created for API docs)",
  email: "some.email@gmail.com",
  address: {
    city: 'Toronto',
    country: 'CA',
    line1: "Some Address",
    line2: "Some unit number",
    postal_code: "M5G0V1",
    state: "ON",
  },
  name: "Some Name",
  phone: "Some Number",
}); 
const price = await stripe.prices.create({
  unit_amount: 599,
  currency: 'cad',
  recurring: {interval: 'month', interval_count: '1'},
  product: 'prod_KZfHFK4nfCqlGS',
});
const session = await stripe.checkout.sessions.create({
  success_url: 'http://localhost:8080/stripeSessionSuccessHook',
  cancel_url: 'http://localhost:8080/stripeSessionCancelHook',
  payment_method_types: ['card'],
  customer: customer.id,
  line_items: [
    {price: price.id, quantity: 1},
  ],
  mode: 'subscription',
  // 新增订阅计划配置
  subscription_schedule_data: {
    end_behavior: 'cancel',
    phases: [
      {
        items: [
          {
            price: price.id,
            quantity: 1,
          },
        ],
        iterations: 24,
      },
    ]
  }
});

以上配置会让Checkout付款成功后自动生成符合24个月按月付费要求的订阅，到期后自动取消，不会出现重复订阅的问题。
