Question

第一次问这里，环顾四周后，仍然卡住了试图用Django实施tranzila付款方式，这很容易库存到发送产品购物车我是什么意思我的网站给了我一个购物车，客户可以一起购买几种不同的产品，我想将此数据发送到tranzila tranzila将其接收为rawurlencoded json 进行编码后，出现TypeError：quote_from_bytes（）预期的字节数

我的代码：

def cart_detail(request, total=0, counter=0, cart_items=None):
json_purchase_data = None
cart_data = []
try:
    # get session key
    cart = Cart.objects.get(cart_id=_cart_id(request))
    cart_items = CartItem.objects.filter(cart=cart, active=True)
    for cart_item in cart_items:
        # calculate total
        total += (cart_item.product.price * cart_item.quantity)
        # Item counter
        counter += cart_item.quantity
        # cart items for tranzila
        json_purchase = json.dumps([{"product_name": str(cart_item.product),
                                     "product_quantity": int(cart_item.quantity),
                                     "product_price": int(cart_item.product.price)
                                     }])
        cart_data.append(json_purchase)
    print(cart_data)
except ObjectDoesNotExist:
    pass
# tranzila Code
thtk = create_thtk(total).split("=")[1]
dc_disable = create_dc_disable()
json_purchase_data = quote(cart_data)
if request.method == 'POST':
    form = UserData(request.POST)
else:
    form = UserData()
context = {
    'cart_items': cart_items,
    'total': total,
    'counter': counter,
    'terminal_name': terminal_name,
    'thtk': thtk,
    'dc_disable': dc_disable,
    'form': form,
    'json_purchase_data': json_purchase_data
}
return render(request, 'cart/cart.html', context)
