我使用 python/Django 開發電子商務網站。我集成了條帶支付，其中購物車項目作為行項目動態傳遞。如果購物車價值低于 500 盧比，我會添加運費。當前使用 stripe session Api 進行結賬流程。我想將送貨費作為額外金額添加到結帳訂單項價格中。提前致謝@csrf_exemptdef createCheckoutSession(request):if request.method=='GET': domain_url='http://localhost:8000/' stripe.api_key= settings.STRIPE_SECRET_KEY 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)})

有幾種方法可以解決這個問題，但一種方法是通過儀表板或 API 創建交貨價格。然后，如果訂單項價格總和unit_amounts小于 500，則將運費添加到訂單項并將項目數組傳遞給會話創建調用：
# 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",
)
