Description

I am getting below issue while processing paytm payments and returning back to my Django application.
Below is my code in views.py

from django.http import HttpResponse
from django.shortcuts import render
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth.decorators import login_required
from django.conf import settings
from paytm import checksum
from paytm.models import PaymentHistory

@login_required
def payment(request):
    CALLBACK_URL = settings.HOST_URL + settings.PAYTM_CALLBACK_URL
    order_id = checksum.__id_generator__()

    bill_amount = request.POST['amount']
    if bill_amount:
        data_dict = {
                    'MID':settings.PAYTM_MERCHANT_ID,
                    'ORDER_ID':order_id,
                    'TXN_AMOUNT': bill_amount,
                    'CUST_ID':request.user.email,
                    'INDUSTRY_TYPE_ID':settings.PAYTM_INDUSTRY_TYPE,
                    'WEBSITE': settings.PAYTM_WEBSITE,
                    'CHANNEL_ID':'WEB',
                    'CALLBACK_URL':CALLBACK_URL,
                }
        param_dict = data_dict
        param_dict['CHECKSUMHASH'] = checksum.generate_checksum(data_dict, settings.PAYTM_MERCHANT_KEY)
        return render(request,"paytm/payment.html",{'paytmdict':param_dict})
    return HttpResponse("Bill Amount Could not find. ?bill_amount=10")

@login_required
@csrf_exempt
def response(request):
    if request.method == 'GET':
        return render(request, 'paytm/home.html')
    elif request.method == "POST":
        data_dict = {}
        for key in request.POST:
            data_dict[key] = request.POST[key]
        verify = checksum.verify_checksum(data_dict, settings.PAYTM_MERCHANT_KEY, data_dict['CHECKSUMHASH'])
        if verify:
            for key in request.POST:
                if key == "BANKTXNID" or key == "RESPCODE":
                    if request.POST[key]:
                        data_dict[key] = int(request.POST[key])
                    else:
                        data_dict[key] = 0
                elif key == "TXNAMOUNT":
                    data_dict[key] = float(request.POST[key])
            PaymentHistory.objects.create(user=request.user, **data_dict)
            return render(request,"paytm/response.html",{"paytm":data_dict})
        else:
            return HttpResponse("checksum verify failed")
    return HttpResponse(status=200)

Code in urls.py

from django.urls import path
from paytm import views

urlpatterns = [
    path('', views.response, name='home'),
    path('payment/', views.payment, name='payment'),
    path('response/', views.response, name='response'),
]

Here's my trace back exception details.

Thanks for the report, however IMO it is some Windows issue related with sockets maybe antivirus or firewall blocks connections, it is hard to tell. Nevertheless it is a support issue.

Closing per TicketClosingReasons/UseSupportChannels.

Is this not just the browser shutting the connection, after some time perhaps? (What’s the keep-alive timeout?)

I see this kind of thing on macOS all the time:

It’s expected behaviour.
