Django Error : CSRF cookie not set

Django version: 1.11.11

This error occurred when you try to submit POST form via Postman 2 App

My temporary solution is disabling CSRF Checking by creating a custom middleware.

Just create a new file on the same folder with your file, let’s name it and put these code:

from django.utils.deprecation import MiddlewareMixinfrom django.utils.deprecation import MiddlewareMixin
class DisableCsrfCheck(MiddlewareMixin):
 def process_request(self, req): attr = '_dont_enforce_csrf_checks' if not getattr(req, attr, False): setattr(req, attr, True)

then add this on before django’s CSRF middleware:



Shell – Check SSL Certificate

Just a few minutes after trying to check domain’s SSL Certificate expiry date with python which requires around ten lines of code, I found a shell script which doing that task in just one line, here’s the script


echo | openssl s_client -servername -connect 2>/dev/null | openssl x509 -noout -dates



Python – Check SSL Certificate Expiry Date

Just playing with python 3 to make a simple utility to check my domain expiry date

# save as

import OpenSSL
import ssl, socket
import argparse

# get domain
parser = argparse.ArgumentParser()
args = parser.parse_args()
domain = args.domain

# get SSL Cert info
cert = ssl.get_server_certificate((domain, 443))
x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
x509info = x509.get_notAfter()

exp_day = x509info[6:8].decode(‘utf-8’)
exp_month = x509info[4:6].decode(‘utf-8’)
exp_year = x509info[:4].decode(‘utf-8’)

exp_date = str(exp_day) + “-” + str(exp_month) + “-” + str(exp_year)

print(“SSL Certificate for domain”, domain, “will be expired on (DD-MM-YYYY)”, exp_date)

then run with the domain you want to check as the argument
