# A more versatile way to define event hooks than the YAML format of `config.yaml` is through native Python scripts.

The HTTP backend is a general-purpose web server that you can leverage:
The HTTP backend is a general-purpose web server.
* To execute Platypush commands via HTTP calls. Example::
Example configuration:
curl -XPOST -H 'Content-Type: application/json' -H "X-Token: your_token" \\
-d '{
"type":"request",
"target":"nodename",
"action":"tts.say",
"args": {"phrase":"This is a test"}

websocket_port: 8009
# External folders that will be exposed over `/resources/<name>`
resource_dirs:
photos: /mnt/hd/photos
videos: /mnt/hd/videos
music: /mnt/hd/music
You can leverage this backend:
* To execute Platypush commands via HTTP calls. In order to do so:
** Register a user to Platypush through the web panel (usually served on ``http://host:8008/``).
** Generate a token for your user, either through the web panel (Settings -> Generate Token) or via API:
.. code-block:: shell
curl -XPOST -H 'Content-Type: application/json' -d '
{
"username": "$YOUR_USER",
"password": "$YOUR_PASSWORD"
}' http://host:8008/auth
** Execute actions through the ``/execute`` endpoint:
.. code-block:: shell
curl -XPOST -H 'Content-Type: application/json' -H "Authorization: Bearer $YOUR_TOKEN" -d '
{
"type": "request",
"action": "tts.say",
"args": {
"text": "This is a test"
}
}' http://localhost:8008/execute
* To interact with your system (and control plugins and backends) through the Platypush web panel,
by default available on your web root document. Any plugin that you have configured and available as a panel
plugin will appear on the web panel as well as a tab.
by default available on ``http://host:8008/``. Any configured plugin that has an available panel
plugin will be automatically added to the web panel.
* To display a fullscreen dashboard with your configured widgets, by default available under ``/dashboard/<dashboard_name>``
* To display a fullscreen dashboard with custom widgets.
* To stream media over HTTP through the ``/media`` endpoint
** Widgets are available as Vue.js components under
``platypush/backend/http/webapp/src/components/widgets``.
** Explore their options (some may require some plugins or backends to be configured in order to work) and
create a new dashboard template under ``~/.config/platypush/dashboards``- e.g. ``main.xml``:
.. code-block:: xml
<Dashboard>
<!-- Display the following widgets on the same row. Each row consists of 12 columns.
You can specify the width of each widget either through class name (e.g. col-6 means
6 columns out of 12, e.g. half the size of the row) or inline style
(e.g. `style="width: 50%"`). -->

other music plugin enabled. -->

<!-- Show current date, time and weather. It requires a `weather` plugin or backend enabled -->
<DateTimeWeather class="col-3" />

<!-- Display the following widgets on a second row -->

<!-- Show a carousel of images from a local folder. For security reasons, the folder must be
explicitly exposed as an HTTP resource through the backend `resource_dirs` attribute. -->
<ImageCarousel class="col-6" img-dir="/mnt/hd/photos/carousel" />
<!-- Show the news headlines parsed from a list of RSS feed and stored locally through the
`http.poll` backend -->
<RssNews class="col-6" db="sqlite:////path/to/your/rss.db" />
</Row>
</Dashboard>
** The dashboard will be accessible under ``http://host:8008/dashboard/<name>``, where ``name=main`` if for
example you stored your template under ``~/.config/platypush/dashboards/main.xml``.
* To expose custom endpoints that can be called as web hooks by other applications and run some custom logic.
All you have to do in this case is to create a hook on a
:class:`platypush.message.event.http.hook.WebhookEvent` with the endpoint that you want to expose and store
it under e.g. ``~/.config/platypush/scripts/hooks.py``:
.. code-block:: python
from platypush.context import get_plugin
from platypush.event.hook import hook
from platypush.message.event.http.hook import WebhookEvent
hook_token = 'abcdefabcdef'
# Expose the hook under the /hook/lights_toggle endpoint
@hook(WebhookEvent, hook='lights_toggle')
def lights_toggle(event, **context):
# Do any checks on the request
assert event.headers.get('X-Token') == hook_token, 'Unauthorized'
# Run some actions
lights = get_plugin('light.hue')
lights.toggle()
Any plugin can register custom routes under ``platypush/backend/http/app/routes/plugins``.
Any additional route is managed as a Flask blueprint template and the `.py`
module can expose lists of routes to the main webapp through the
``__routes__`` object (a list of Flask blueprints).
Note that if you set up a main token, it will be required for any HTTP
interaction - either as ``X-Token`` HTTP header, on the query string
(attribute name: ``token``), as part of the JSON payload root (attribute
name: ``token``), or via HTTP basic auth (any username works).
Security: Access to the endpoints requires at least one user to be registered. Access to the endpoints is regulated
in the following ways (with the exception of event hooks, whose logic is up to the user):
* **Simple authentication** - i.e. registered username and password.
* **JWT token** provided either over as ``Authorization: Bearer`` header or ``GET`` ``?token=<TOKEN>``
parameter. A JWT token can be generated either through the web panel or over the ``/auth`` endpoint.
* **Global platform token**, usually configured on the root of the ``config.yaml`` as ``token: <VALUE>``.
It can provided either over on the ``X-Token`` header or as a ``GET`` ``?token=<TOKEN>`` parameter.
* **Session token**, generated upon login, it can be used to authenticate requests through the ``Cookie`` header
(cookie name: ``session_token``).
