在 suds 请求发送中找不到 404 错误 - python - django

Question

我正在为我的网站设置在线支付门户。 我使用下面的代码：

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')

但在它显示付款门之前，它会产生一个错误：

/business/upgrade/ 中的异常
（404，“未找到”）
请求方法：POST
请求网址：http://localhost:8000/business/upgrade/ Django 版本：1.11.4 异常类型：异常 异常值：
（404，'未找到'）

而错误在于这行代码：

result = client.service.PaymentRequest(MERCHANT_ID, amount, description, email, mobile, CallbackURL)

有什么问题？我该如何解决？ 谢谢

* 更新*
下面的 sn-p 是我的 urls.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'),
]

Answer 1

这里有很多东西没有任何意义。

首先，您不能告诉您的支付服务提供商使用 127.0.0.1 地址回调您的网站。那只是您的本地主机；但显然网关在 Internet 上的其他地方。它需要有一个可以调用的站点的实际地址。

其次，与您的问题无关但仍然是一个非常严重的问题，您绝对不能使用这样的全局变量。这些将由您网站的所有用户共享，因此金额将全部混淆。我对这个支付提供商一无所知，但我绝对确定它会在回调的参数中提供金额。
