WARNING: This integration is deprecated, since it was practically only used for RSS subscriptions.
RSS feeds integration has been replaced by :class:`platypush.plugins.rss.RSSPlugin`.
This backend will poll multiple HTTP endpoints/services and return events
the bus whenever something new happened. Supported types:
:class:`platypush.backend.http.request.JsonHttpRequest` (for polling updates on
a JSON endpoint), :class:`platypush.backend.http.request.rss.RssUpdates`
(for polling updates on an RSS feed). Example configuration::
backend.http.poll:
requests:
-
# Poll for updates on a JSON endpoint
method: GET
type: platypush.backend.http.request.JsonHttpRequest
args:
url: https://host.com/api/v1/endpoint
headers:
Token: TOKEN
params:
updatedSince: 1m
timeout: 5 # Times out after 5 seconds (default)
poll_seconds: 60 # Check for updates on this endpoint every 60 seconds (default)
path: ${response['items']} # Path in the JSON to check for new items.
# Python expressions are supported.
# Note that 'response' identifies the JSON root.
# Default value: JSON root.
-
# Poll for updates on an RSS feed
type: platypush.backend.http.request.rss.RssUpdates
url: https://www.theguardian.com/rss/world
title: The Guardian - World News
poll_seconds: 120
max_entries: 10
Triggers: an update event for the relevant HTTP source if it contains new items. For example:
* :class:`platypush.message.event.http.rss.NewFeedEvent` if a feed contains new items
* :class:`platypush.message.event.http.HttpEvent` if a JSON endpoint contains new items
