Abstraction library to send push notifications through APNs, GCM and OneSignal

Abstraction library to send push notifications through APNs, GCM and OneSignal.

Caution!

This library is in early development state.

Caution!

This library only supports Python 3.5

Requirements

Caution!

Requirements are not installed automatically by pip. The recomended dependencies can be found in requirements.txt.

For APNs an @oeegor/apns2-client fork is used, pypn branch

https://github.com/alej0varas/apns2-client.git

For GCM @geeknam/python-gcm develop branch is used.

https://github.com/geeknam/python-gcm.git

For OneSignal yaosac.

https://pypi.python.org/pypi/yaosac

Usage

APNS

apns = pypn.Notification(pyvenv.APNS)
apns.send(token, data)

Possible values for token are:

• A string

• A list of string

Currently sending multiple notifications means iterating over the list and send one request per user.

GCM

gcm = pypn.Notification(pyvenv.APNS)
gcm.send(token, data)

Possible values for token are:

• A string

  • registration_id or topic (just the name, without “/topic/”)

• A list of string, registration_ids

OneSignal

ones = pypn.Notification(pyvenv.OS)
ones.send(token, data)

Possible values for token are:

• A list of OneSignal’s player_id

You need an App Auth Key and App Id. They can be set as environment variables ‘OS_APP_AUTH_KEY’ and ‘OS_APP_ID’ or assigned to the client via user_auth_key and app_id attributes.

Data

PyPN has been built as a layer in between a “back-end”(I’m working on a Django application to handle data) and the existing push notification libraries. That means notifications are defined including all the required fields for each provider. This data is then passed to PyPN together with the provider “name”.

Example data

Not every field value is set.

data = {
   # Common fields
   'body': '1, 2, 3, ... push sucks!'
   'sound': 'default',
   'priority': 'high',
   'title': 'Hello, World!',

   # APNs aps
   'apns_badge': 69,
   'apns_content_available': 1,
   'apns_category': '',
   'apns_mutable_content': True,
   # APNs alert
   'apns_alert_title_loc_key': '',
   'apns_alert_title_loc_args': '',
   'apns_alert_loc_key': '',
   'apns_alert_loc_args': '',
   'apns_alert_action_loc_key': '',
   'apns_alert_launch_image': '',
   # APNs data
   'apns_custom': {'custom': 'values'},

   # GCM data
   'gcm_data': {'custom': 'values'},
   # GCM notification
   'gcm_notification_icon': '',
   'gcm_notification_tag': '',
   'gcm_notification_color': '',
   'gcm_notification_click_action': '',
   'gcm_notification_body_loc_key': '',
   'gcm_notification_body_loc_args': '',
   'gcm_notification_title_loc_key': '',
   'gcm_notification_title_loc_args': '',
   # GCM options
   'gcm_option_collapse_key': '',
   'gcm_option_content_available': '',
   'gcm_option_delay_while_idle': '',
   'gcm_option_time_to_live': 40320,
   'gcm_option_restricted_package_name': '',
}

Credentials

Credentials are expected to be in placed in the environment.

For APNs the path to the .pem certificate and the pass-phrase if any:

• APNS_CERT_FILE

• APNS_CERT_PASSWORD

For GCM the server key:

• GCM_SERVER_KEY

For OneSignal the application id and the API key:

• OS_APP_AUTH_KEY

• OS_APP_ID

Debug

Debug is the default value for every provider(you will not get notifications through GCM unless you set debug to false). This can also be set in the environment:

• APNS_MODE: Possible values are “dev” and “prod”

• GCM_DRY_RUN: Possible values are 0 and 1

• There is no debug mode for OneSignal :(

Also logging for the gcm library can be enabled setting GCM_LOGGING environment variable to 1.
