我正在开发一个使用django-oscar框架的购物网站,事实上我正在使用他们的沙盒网站。我想在结账过程中增加付款,但问题是,我完全搞不清了!在
我读过这个链接:"Oscar's payment integration docs"
我有大局观的东西。我也看了文件视图.py但我有几个问题在网上找不到。在
我的问题是,我应该重写或创建哪些方法/类来处理以下过程:
在用户请求付款后,我应该向银行发送请求并给他们所需的参数(代码中的pay_request_参数)
然后,他们会发送一个Id,确认我的访问权限,然后我将该Id发布到一个地址,并将用户重定向到银行的网页。在
当用户成功地向银行付款后,他们会通知我在第一步中提供的回拨url。在
有了这些信息,我应该核实付款是否成功,如果成功,我应该要求银行结算,把钱寄给我。在
现在我的代码完成了前两个步骤,但是我不知道在沙盒中重定向之后如何处理这个过程。我的代码是:
from oscar.apps.checkout import views
from oscar.apps.payment import models
from oscar.apps.payment.exceptions import *
import requests
import datetime
mellat_services_url = 'https://bpm.shaparak.ir/pgwchannel/services/pgw?wsdl'
start_pay_url = 'https://bpm.shaparak.ir/pgwchannel/startpay.mellat'
terminal_id = 'xxx'
username = 'xxx'
password = 'xxx'
# Subclass the core Oscar view so we can customise
class PaymentDetailsView(views.PaymentDetailsView):
def handle_payment(self, order_number, total, **kwargs):
# Talk to payment gateway. If unsuccessful/error, raise a
# PaymentError exception which we allow to percolate up to be caught
# and handled by the core PaymentDetailsView.
# mellat cycle start
local_date = str(datetime.date.today())[0:4] + str(datetime.date.today())[5:7] + str(datetime.date.today())[8:10]
local_time = str(datetime.datetime.now().time())[0:2] + str(datetime.datetime.now().time())[3:5] + str(datetime.datetime.now().time())[6:8]
# call bpPayRequest and get refId
pay_request_parameters = {'terminalId': terminal_id, 'userName': username,
'userPassword': password, 'orderId': order_number,
'amount': total.incl_tax, 'localDate': local_date,
'localTime': local_time, 'additionalData': ""
'callBackUrl': 'mysite.com/checkout/preview/'}
pay_request_answer = requests.post(mellat_services_url, pay_request_parameters)
if not pay_request_answer.split(",")[0] == 0:
response_code = pay_request_answer.split(",")[0]
if response_code[0] == '1':
raise UnableToTakePayment()
else:
raise PaymentError()
requests.post(start_pay_url, pay_request_answer.split(",")[1])
raise RedirectRequired(start_pay_url)
# post the refId to bank and then redirect customer to the bank
# apparently wait for the bank ( like for 10 mins ) to get the payment status
# if the bank responded with success, the you verify the payment with a post to the bank
# if everything was verified, tell the bank for a settlement
# mellat cycle end
#The rest should be implemented but I dont know where I should put this
#All I know is that it should be done after the verification with the data
#sent from the bank.
reference = gateway.pre_auth(order_number, total.incl_tax, kwargs['bankcard'])
# Payment successful! Record payment source
source_type, __ = models.SourceType.objects.get_or_create(
name="SomeGateway")
source = models.Source(
source_type=source_type,
amount_allocated=total.incl_tax,
reference=reference)
self.add_payment_source(source)
# Record payment event
self.add_payment_event('pre-auth', total.incl_tax)
提前谢谢。在
我遇到了一个类似的问题,我所做的是将来自银行的callBackUrl重定向到一个实现如下的视图:
