Pullkin

Like Pushkin, but subscribe to FCM (GCM) and receive notifications

My alternative implementation of python implementation of JS implementation

Tested on python (3.9.6, TODO: other versions)

I almost didn't write anything to consider it my intellectual property, just wrapped the code already written by Franc[e]sco in a design convenient for my own use

Note that for the listening part Franc[e]sco has to pull in http-ece which depends on a full blown native crypto library rather than just oscrypto. it is an optional dependency so you'll have to install it explicitly by depending on pullkin[listen]

Usage

pip install pullkin

Basic usage example that stores and loads credentials and persistent ids and prints new notifications

You can also run this example with this command (change the sender id)

python -m pullkin --sender-id=722915550290

Compatibility with Franc[e]sco version

You should import familiar functions from pullkin.old instead of push_receiver

from pullkin.old import register, listen
import json


def on_notification(obj, notification, data_message):
  idstr = data_message.persistent_id + "\n"

  # check if we already received the notification
  with open("persistent_ids.txt", "r") as f:
    if idstr in f:
      return

  # new notification, store id so we don't read it again
  with open("persistent_ids.txt", "a") as f:
    f.write(idstr)

  # print notification
  n = notification["notification"]
  text = n["title"]
  if n["body"]:
    text += ": " + n["body"]
  print(text)


if __name__ == "__main__":
  SENDER_ID = 722915550290  # change this to your sender id

  try:
    # already registered, load previous credentials
    with open("credentials.json", "r") as f:
      credentials = json.load(f)

  except FileNotFoundError:
    # first time, register and store credentials
    credentials = register(sender_id=SENDER_ID)
    with open("credentials.json", "w") as f:
      json.dump(credentials, f)

  print("send notifications to {}".format(credentials["fcm"]["token"]))

  with open("persistent_ids.txt", "r+") as f:
    received_persistent_ids = [x.strip() for x in f]

  listen(credentials, on_notification, received_persistent_ids)
