pytInstall Python (on OS X Yosemite)
Yosemite has Python 2.7.6 built in but for many reasons (one of them is sudo) we prefer a clean up-to-date install.
1. brew install python
Make sure the newly installed Python is in the path:
vi ~/.zshrc PATH=$PATH:/usr/local:/usr/local/bin: # Add Python to PATH source ~/.zshrc
Double check we have the latest version:
Virtual environments is a must to keep all the dependencies in check:
pip install virtualenv
Create a new virtual environment called pyenv and activate it:
virtualenv pyenv source pyenv/bin/activate
Install Python APN library:
pip install apns
Now it is a good idea to make our installation easily repeatable:
pip freeze > requirements.txt
Later we can restore all the required libraries:
pip install -r requirements.txt
Or even update them all:
pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs pip install -U
From developer.apple.com download “APNs Production iOS” certificate, aps_production.cer.
Now, this is the tricky part. We have to convert it to a .p12 certificate.
To do that, double-click on the certificate so that it is added to the keychain.
Open “Keychan Access” and right-click on the certificate to export it as .p12 certificate.
It is very important to export the certificate and not the private key!
Lets export it into a PEM certificate that either contains both the private key and the certificate:
openssl pkcs12 -in aps_production.p12 -out aps_production_olinguito.pem -nodes
Or into two separate files, one with the key and the other one with the certificate (preferred method):
openssl pkcs12 -nocerts -in aps_production.p12 -out aps_prod_key.pem -nodes openssl pkcs12 -nokeys -in aps_production.p12 -out aps_prod_cert.pem -nodes
A very simple script to test our notifications:
import time from apns import APNs, Frame, Payload apns = APNs(use_sandbox=False, cert_file='aps_prod_cert.pem', key_file='aps_prod_key.pem', enhanced=True) # Send a notification token_hex = 'dd6b492f92546f8a02d9a36e689b4be28b0c663db7b6c278379866a7e1behell' payload = Payload(alert="Hello World!", sound="default", badge=1) apns.gateway_server.send_notification(token_hex, payload)
