pip install exponent_server_sdk
Use to send push notifications to Exponent Experiences from a Python server.
Full documentation on the API is available if you want to dive into the details.
Here's an example on how to use this with retries and reporting via pyrollbar.
from exponent_server_sdk import (
DeviceNotRegisteredError,
PushClient,
PushMessage,
PushResponseError,
PushServerError,
)
from requests.exceptions import ConnectionError, HTTPError
# Basic arguments. You should extend this function with the push features you
# want to use, or simply pass in a `PushMessage` object.
def send_push_message(token, message, extra=None):
try:
response = PushClient().publish(
PushMessage(to=token,
body=message,
data=extra))
except PushServerError as exc:
# Encountered some likely formatting/validation error.
rollbar.report_exc_info(
extra_data={
'token': token,
'message': message,
'extra': extra,
'errors': exc.errors,
'response_data': exc.response_data,
})
raise
except (ConnectionError, HTTPError) as exc:
# Encountered some Connection or HTTP error - retry a few times in
# case it is transient.
rollbar.report_exc_info(
extra_data={'token': token, 'message': message, 'extra': extra})
raise self.retry(exc=exc)
try:
# We got a response back, but we don't know whether it's an error yet.
# This call raises errors so we can handle them with normal exception
# flows.
response.validate_response()
except DeviceNotRegisteredError:
# Mark the push token as inactive
from notifications.models import PushToken
PushToken.objects.filter(token=token).update(active=False)
except PushTicketError as exc:
# Encountered some other per-notification error.
rollbar.report_exc_info(
extra_data={
'token': token,
'message': message,
'extra': extra,
'push_response': exc.push_response._asdict(),
})
raise self.retry(exc=exc)
