from django.http import HttpResponse
from django.utils import simplejson
import json
from push.models import iPhone

def SendMessage(request,data):

        t = iPhone('XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX ') # 64 digit token
        t.send_message("hi") # at this line i am getting ERROR
        return HttpResponse(data,mimetype='application/javascript')

settings.py

import os
PROJECT_ROOT = '/'

# Full path to the APN Certificate / Private Key .pem
IPHONE_SANDBOX_APN_PUSH_CERT = os.path.join(PROJECT_ROOT, "apns-dev-tubeteam.pem")
IPHONE_LIVE_APN_PUSH_CERT = os.path.join(PROJECT_ROOT, "apns-dev-tubeteam.pem")

# Set this to the hostname for the outgoing push server
IPHONE_SANDBOX_APN_HOST = 'gateway.sandbox.push.apple.com'
IPHONE_LIVE_APN_HOST = 'gateway.push.apple.com'

# Set this to the hostname for the feedback server
IPHONE_SANDBOX_FEEDBACK_HOST = 'feedback.sandbox.push.apple.com'
IPHONE_LIVE_FEEDBACK_HOST = 'feedback.push.apple.com'

Error

[Errno 336265218] _ssl.c:337: error:140B0002:SSL routines:SSL_CTX_use_PrivateKey_file:system lib

Can anyone please do tell me how to get rid off it.

Answer 1

I had the exact same problem. Turns out it was a simple error - I had a mistake in IPHONE_SANDBOX_APN_PUSH_CERT and python could not locate my certificate. Once I pointed it to the right location, it started working.

Note that you might want to double-check your certificate first using openssl command line, such as:

openssl x509 -text -in cert.pem

That will give you textual information about your certificate, its validity, etc.

Also, double-check file permissions of the certificate file (the python process must have sufficient rights to access it).
