404在suds请求send python djang中找不到错误

Question

我正在为我的网站设置在线支付门户。 我使用以下代码：

ZARINPAL_WEBSERVICE ='https://www.zarinpal.com/pg/services/WebGate/wsdl'  # Required
MERCHANT_ID = 'blah-blah-blah'  # Required
amount = 0

@method_decorator(login_required, name='dispatch')
class Upgrade(View):
    def get(self, request):
        current_plan = UserPlan.objects.filter(user=request.user).first()
        all_plans = Plans.objects.all()
        old_plans = None
        if current_plan:
            new_plans = all_plans.filter(no__gt=current_plan.no)
            old_plans = all_plans.filter(no__lte=current_plan.no)
        else:
            new_plans = all_plans

        return render(request, 'business/upgrade.html', {'current_plan': current_plan,
                                                     'new_plans': new_plans,
                                                     'old_plans': old_plans})

    def post(self, request):
        current_plan = UserPlan.objects.filter(user=request.user).first()
        form = UpgradeForm(request.POST)
        if form.is_valid():
            new_plan = form.cleaned_data.get('requested_plan')
            requested_plan = Plans.objects.filter(no=new_plan).first()
            global amount
            if current_plan:
                amount = requested_plan.price - current_plan.price
            else:
                amount = requested_plan.price

            # redirect to ZarinPal page and send data to it
            description = u'TEST DESCRIPTION'  # Required
            email = form.cleaned_data.get('email')  # Optional
            mobile = form.cleaned_data.get('phone')  # Optional
            CallbackURL = 'http://127.0.0.1:8000/business/verify/'
            client = Client(ZARINPAL_WEBSERVICE)
            result = client.service.PaymentRequest(MERCHANT_ID, amount, description, email, mobile, CallbackURL)
            if result.Status == 100:
                return redirect('https://www.zarinpal.com/pg/StartPay/' + result.Authority)
            else:
                return HttpResponse('Error')
        else:
            messages.error(request, form.errors)
            print(form.errors)
            return redirect('upgrade_plan')


@login_required
def verify(request):
    client = Client(ZARINPAL_WEBSERVICE)
    if request.GET.get('Status') == 'OK':
        result = client.service.PaymentVerification(MMERCHANT_ID,
                                                request.GET['Authority'],
                                                amount)
        if result.Status == 100:
            # in this step, it must create or update UserPlan row in DB.
        # also, it should be create a row in Sells table and save transaction defatils.

            return HttpResponse('Transaction was successfull. RefID: ' + str(result.RefID))
        elif result.Status == 101:
            return HttpResponse('Transaction submitted : ' + str(result.Status))
        else:
            return HttpResponse('Transaction failed. Status: ' + str(result.Status))
    else:
        return HttpResponse('Transaction failed or canceled by user')

但在显示付款门之前，它会生成一个错误：

Exception at /business/upgrade/
(404, 'Not Found')
Request Method: POST
Request URL: http://localhost:8000/business/upgrade/ Django Version: 1.11.4 Exception Type: Exception Exception Value:
(404, 'Not Found')

错误是针对这行代码：

^{pr2}$

怎么了？我该怎么解决呢？ 谢谢

*更新*
下面的片段是我的网址.py文件：

from django.conf.urls import url
from . import views
urlpatterns = [
    # for explicit urls
    url(r'^upgrade/$', views.Upgrade.as_view(), name='upgrade_plan'),
    url(r'^verify/$', views.verify, name='verify'),
]

这里有很多事情没有任何意义。在

首先，你不能让你的支付提供商用127.0.0.1地址回拨你的网站。这只是您的本地主机；但显然网关位于Internet的其他位置。它需要有一个你的网站的实际地址，它可以调用。在

第二，与你的问题无关但仍然是一个非常严重的问题，你绝对不能像这样使用全局变量。这些将被你的网站的所有用户共享，所以数量会全部混在一起。我不知道这个支付提供者的任何信息，但我绝对确定它会在回调参数中提供金额。在
