python - 我无法在 python 中使用 zeep - 缺少元素 CallbackURL 错误

Question

我想用 zeep 模块在 django 中创建一个支付网关。我想使用本地托管测试这个支付网关。我从一个生产支付网关的网站获得了帮助并编写了以下代码:

views.py

from django.shortcuts import render, redirect
from django.http import HttpResponse
from zeep import Client

MERCHANT = '00'
client = Client('https://www.zarinpal.com/pg/services/WebGate/wsdl')
amount = 1000
description = 'تست درگاه پرداخت'
CallbackURL = 'http://localhost:8000/' #whatever! i am just testing

def send_request(request):
    result = client.service.PaymentRequest(MERCHANT, amount, description, CallbackURL)
    if result.Status == 100:
        return redirect('https://www.sandbox.zarinpal.com/pg/StartPay/' + str(result.Authority))
    else:
        return HttpResponse('Error code: ' + str(result.Status))

def verify(request):
    if request.GET.get('Status') == 'OK':
        result = client.service.PaymentVerification(MERCHANT, request.GET['Authority'], amount)
        if result.Status == 100:
            return HttpResponse('Transaction success.\nRefID: ' + str(result.RefID))
        elif result.Status == 101:
            return HttpResponse('Transaction submitted : ' + str(result.Status))
        else:
            return HttpResponse('Transaction failed.\nStatus: ' + str(result.Status))
    else:
        return HttpResponse('Transaction failed or canceled by user')

运行服务器时出现以下错误:

Exception Value: Missing element CallbackURL (PaymentRequest.CallbackURL)

Exception Location:C:\Users\HP\AppData\Local\Programs\Python\Python37-32\lib\site-packages\zeep\xsd\elements\element.py in validate, line 280

看起来您的 PaymentRequest 端点需要的参数比您提供的要多 - 它需要电子邮件和手机，然后才是 CallbackURL。由于这些是可以为空的，所以您不必提供它们是对的，但是您需要告诉 zeep 最终值适用于 CallbackURL 参数 - 您可以通过关键字参数来执行此操作。

client.service.PaymentRequest(MERCHANT, amount, description, CallbackURL=CallbackURL)
