I am unable to read POST parameters sent by payment gateway after payment
was processed. Payment gateway redirects to returnUrl (I pass this to
payment gateway before payment was processed) with some parameters by POST
request.
In url.py
path('cashfreeresponse/',views.cashfree_response, name='cashfree_response'),
in views.py
@csrf_exempt@login_requireddef cashfree_response(request):
print(request.method)
if request.method == "POST":
print('inside post method')
print(request.POST.get('cf_subReferenceId'))
if request.method == "GET":
print('inside get method')
print(request.GET.get('cf_subReferenceId'))
print(request.method) is showing as GET but it was supposed be POST method
also print(request.GET.get('cf_subReferenceId')) and
print(request.POST.get('cf_subReferenceId')) are showing as None.
But it looks like payment gateway sending parameters as POST method. When I
pass returnUrl as http://127.0.0.1:8000/cashfreeresponse instead of
http://127.0.0.1:8000/cashfreeresponse/ ('/' is missing in the first one)
then I am getting error as
You called this URL via POST, but the URL doesn't end in a slash and you
have APPEND_SLASH set. Django can't redirect to the slash URL while
maintaining POST data. Change your form to point to
127.0.0.1:8000/cashfreeresponse/ (note the trailing slash), or set
APPEND_SLASH=False in your Django settings.
but I see in my google chrome page that payment gateway sending parameters
with POST request. Below image shows parameters sent by payment gateway by
POST request

If I change urls.py to
path('cashfreeresponse',views.cashfree_response, name='cashfree_response'),
in settings.py to
APPEND_SLASH = False
and returnUrl to http://127.0.0.1:8000/cashfreeresponse then I am not
getting any error but still not receiving any parameters. How do I read
those parameters sent by payment gateway by POST request? Here
<https://docs.cashfree.com/docs/sbc/guide/#payment-response> is the
documentation for payment gateway.
