将额外金额添加到条带结帐

Question

我正在使用 python/Django 开发电子商务网站。我已经集成了条带付款，其中购物车项目作为行项目动态传递。如果购物车价值低于 500 卢比，我添加了运费。当前使用条带会话 Api 进行结帐过程。我想将运费作为额外金额添加到结帐行项目价格中。 提前致谢

    profile = UserProfile.objects.get(user__id=request.user.id)


    try:
        customer = stripe.Customer.retrieve(profile.stripe_id)
        print (customer)
        profile = UserProfile.objects.get(user__id=request.user.id)
        checkoutSession = stripe.checkout.Session.create(
        success_url =domain_url+'success?session_id={CHECKOUT_SESSION_ID}',
        cancel_url =domain_url+'cancelled/',
        payment_method_types = ['card'],
        mode='payment',
        line_items= get_line_items(request)[0],
        customer= profile.stripe_id,


        )



        return JsonResponse({'sessionId':checkoutSession['id']})


    except Exception as e:
        return JsonResponse({"error":str(e)})

有几种方法可以解决此问题，但其中一种方法是通过仪表板或 API 创建交付价格。然后，如果行项目价格的总和 unit_amounts 小于 500，则将运输价格添加到行项目并将项目数组传递给会话创建调用：

# The shipping price ID
shipping_price = "price_xxx"

# Base price
price = stripe.Price.retrieve(
  "price_yyy",
)

# If there are more than one item you can iterate over items and sum the unit_amounts
items = [
  {
    "price": price.id,
    "quantity": 1,
  },
]

# For simplicity I assume there is only one price being charged, for summing, iterate over the items
if(price.unit_amount < 500):
  items.append({
    "price": shipping_price,
    "quantity": 1,
  })

stripe.checkout.Session.create(
  success_url="https://example.com/success",
  cancel_url="https://example.com/cancel",
  payment_method_types=["card"],
  line_items=items,
  mode="payment",
)
