pushjack-http2 2.1.0

Push notifications for APNS (iOS) and GCM (Android)

Push notifications for APNS (iOS) and GCM (Android). It provides HTTP/2 network protocol based APNS client.

Quickstart

Install using pip:

pip install pushjack-http2

Whether using APNS or GCM, pushjack provides clients for each. It also provides a HTTP/2 based APNS client.

APNS (using certificates)

Send notifications using the APNSClient class:

from pushjack_http2 import APNSClient

client = APNSClient(certificate='<path/to/certificate.pem>',
                    default_error_timeout=10,
                    default_expiration_offset=2592000,
                    default_batch_size=100,
                    default_retries=5)

token = '<device token>'
alert = 'Hello world.'

# Send to single device.
# NOTE: Keyword arguments are optional.
res = client.send(token,
                  alert,
                  badge='badge count',
                  sound='sound to play',
                  category='category',
                  content_available=True,
                  title='Title',
                  title_loc_key='t_loc_key',
                  title_loc_args='t_loc_args',
                  action_loc_key='a_loc_key',
                  loc_key='loc_key',
                  launch_image='path/to/image.jpg',
                  extra={'custom': 'data'})

# Send to multiple devices by passing a list of tokens.
client.send([token], alert, **options)

Access response data.

# List of all tokens sent.
res.tokens

# List of errors as APNSServerError objects
res.errors

# Dict mapping errors as token => APNSServerError object.
res.token_errors

Override defaults for error_timeout, expiration_offset, and batch_size.

client.send(token,
            alert,
            expiration=int(time.time() + 604800),
            error_timeout=5,
            batch_size=200)

Send a low priority message.

# The default is low_priority == False
client.send(token, alert, low_priority=True)

Get expired tokens.

expired_tokens = client.get_expired_tokens()

Close APNS connection.

client.close()

For the APNS sandbox, use APNSSandboxClient instead:

from pushjack_http2 import APNSSandboxClient

APNS (using Auth tokens)

Send notifications using the APNSHTTP2Client class:

from pushjack_http2 import APNSHTTP2Client

key = "my_key"

token = apns.APNSAuthToken(
    token=key,
    team_id="my_team_id",
    key_id="my_key_id",
)

client = apns.APNSHTTP2Client(
    token=token,
    bundle_id='my_bundle_id',
)

response = client.send_message(
    device_id="my_device_id",
    message="message",
    content_available=True,
    title="title"
)

Close APNS connection.

client.conn.close()

For the APNS sandbox, use APNSHTTP2SandboxClient instead:

from pushjack_http2 import APNSHTTP2SandboxClient

GCM

Send notifications using the GCMClient class:

from pushjack_http2 import GCMClient

client = GCMClient(api_key='<api-key>')

registration_id = '<registration id>'
alert = 'Hello world.'
notification = {'title': 'Title', 'body': 'Body', 'icon': 'icon'}

# Send to single device.
# NOTE: Keyword arguments are optional.
res = client.send(registration_id,
                  alert,
                  notification=notification,
                  collapse_key='collapse_key',
                  delay_while_idle=True,
                  time_to_live=604800)

# Send to multiple devices by passing a list of ids.
client.send([registration_id], alert, **options)

Alert can also be be a dictionary with data fields.

alert = {'message': 'Hello world', 'custom_field': 'Custom Data'}

Alert can also contain the notification payload.

alert = {'message': 'Hello world', 'notification': notification}

Send a low priority message.

# The default is low_priority == False
client.send(registration_id, alert, low_priority=True)

Access response data.

# List of requests.Response objects from GCM Server.
res.responses

# List of messages sent.
res.messages

# List of registration ids sent.
res.registration_ids

# List of server response data from GCM.
res.data

# List of successful registration ids.
res.successes

# List of failed registration ids.
res.failures

# List of exceptions.
res.errors

# List of canonical ids (registration ids that have changed).
res.canonical_ids

Changelog

v2.1.0 (28-02-2020)

• Import APNSAuthToken to __init__.py.

v1.5.0 (2018-07-29)

• gcm: Use FCM URL instead of deprecated GCM URL. Thanks Lukas Anzinger!

v1.4.1 (2018-06-18)

• apns: Remove restriction on token length due to incorrect assumption about tokens always being 64 characters long.

v1.4.0 (2017-11-09)

• apns: Add exceptions APNSProtocolError and APNSTimeoutError. Thanks Jakub Kleň!

• apns: Add retry mechanism to APNSClient.send. Thanks Jakub Kleň!

  • Add default_retries argument to APNSClient initialization. Defaults to 5.

  • Add retries argument to APNSClient.send. By default will use APNSClient.default_retries unless explicitly passed in.

  • If unable to send after retries, an APNSTimeoutError will be raised.

• apns: Fix bug in bulk APNSClient.send that resulted in an off-by-one error for message identifier in returned errors. Thanks Jakub Kleň!

• apns: Add max payload truncation option to APNSClient.send. Thanks Jakub Kleň!

  • Add default_max_payload_length argument to APNSClient initialization. Defaults to 0 which disabled max payload length check.

  • Add max_payload_length argument to APNSClient.send. By default will use APNSClient.default_max_payload_length unless explicitly passed in.

  • When max_payload_length set, messages will be truncated to fit within the length restriction by trimming the “message” text and appending it with “…”.

v1.3.0 (2017-03-11)

• apns: Optimize reading from APNS Feedback so that the number of bytes read are based on header and token lengths.

• apns: Explicitly close connection to APNS Feedback service after reading data.

• apns: Add support for mutable-content field (Apple Notification Service Extension) via mutable_content argument to APNSClient.send(). Thanks Ahmed Khedr!

v1.2.0 (2015-12-04)

• gcm: Add support for priority field to GCM messages via low_priority keyword argument. Default behavior is for all messages to be "high" priority. This is the opposite of GCM messages but mirrors the behavior in the APNS module where the default priority is "high".

v1.1.0 (2015-10-22)

• gcm: Add support for notification field to GCM messages.

• gcm: Replace registration_ids field with to field when sending to a single recipient since registration_ids field has been deprecated for single recipients.
