如果您希望使用动态定价，我建议您使用Checkout Session，它可以创建一次性付款链接：https://stripe.com/docs/billing/subscriptions/build-subscriptions?ui=checkout
除了使用line_items.price，您还可以使用line_items.price_data，它允许您在创建订阅时创建金额。例如，

const session = await stripe.checkout.sessions.create({
  mode: 'subscription',
  line_items: [
    {
      price_data: {
        unit_amount: 1000,
        currency: 'USD',
        recurring: {
          interval: 'month',
        },
        product_data: {
          name: 'Music Streaming',
        },
      },
      quantity: 1,
    }
  ],
  // {CHECKOUT_SESSION_ID} is a string literal; do not change it!
  // the actual Session ID is returned in the query parameter when your customer
  // is redirected to the success page.
  success_url: 'https://example.com/success.html?session_id={CHECKOUT_SESSION_ID}',
  cancel_url: 'https://example.com/canceled.html',
});
