API Reference
=============

GenieACS exposes a rich RESTful API through its NBI component. This document
serves as a reference for the available APIs.

This API makes use of MongoDB's query language in some of its endpoints. Refer
to MongoDB's documentation for details.

.. note::

  The examples below use ``curl`` command for simplicity and ease of testing.
  Query parameters are URL-encoded, but the original pre-encoding values are
  shown for reference. These examples assume genieacs-nbi is running locally
  and listening on the default NBI port (7557).

.. warning::

  A common pitfall is not properly percent-encoding special characters in the
  device ID or query in the URL.

Endpoints
---------

GET /\<collection\>/?query=\<query\>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Search for records in the database (e.g. devices, tasks, presets, files).
Returns a JSON representation of all items in the given collection that match
the search criteria.

*collection*: The data collection to search. Could be one of: tasks, devices,
presets, objects.

*query*: Search query. Refer to MongoDB queries for reference.

Examples
^^^^^^^^

- Find a device by its ID:

.. code:: javascript

  query = {"_id": "202BC1-BM632w-000000"}

.. code:: bash

  curl -i 'http://localhost:7557/devices/?query=%7B%22_id%22%3A%22202BC1-BM632w-000000%22%7D'

- Find a device by its MAC address:

.. code:: javascript

  query = {
    "InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANIPConnection.1.MACAddress": "20:2B:C1:E0:06:65"
  }

.. code:: bash

  curl -i 'http://localhost:7557/devices/?query=%7B%22InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANIPConnection.1.MACAddress%22%3A%2220:2B:C1:E0:06:65%22%7D'

- Search for devices that have not initiated an inform in the last 7 days.

.. code:: javascript

  query = {
    "_lastInform": {
      "$lt" : "2017-12-11 13:16:23 +0000"
    }
  }

.. code:: bash

  curl -i 'http://localhost:7557/devices/?query=%7B%22_lastInform%22%3A%7B%22%24lt%22%3A%222017-12-11%2013%3A16%3A23%20%2B0000%22%7D%7D'

- Show pending tasks for a given device:

.. code:: javascript

  query = {"device": "202BC1-BM632w-000000"}

.. code:: bash

  curl -i 'http://localhost:7557/tasks/?query=%7B%22device%22%3A%22202BC1-BM632w-000000%22%7D'

- Return specific parameters for a given device:

.. code:: javascript

  query = {"_id": "202BC1-BM632w-000000"}

.. code:: bash

  curl -i 'http://localhost:7557/devices?query=%7B%22_id%22%3A%22202BC1-BM632w-000000%22%7D&projection=InternetGatewayDevice.DeviceInfo.ModelName,InternetGatewayDevice.DeviceInfo.Manufacturer'

The ``projection`` URL param is a comma-separated list of the parameters to receive.

POST /devices/\<device_id\>/tasks?[connection_request]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Enqueue task(s) and optionally trigger a connection request to the device.
Refer to :ref:`tasks` section for information about the task object format.
Returns status code 200 if the tasks have been successfully executed, and 202
if the tasks have been queued to be executed at the next inform.

*device_id*: The ID of the device.

*connection_request*: Indicates that a connection request will be triggered to
execute the tasks immediately. Otherwise, the tasks will be queued and be
processed at the next inform.

The response body is the task object as it is inserted in the database. The
object will include ``_id`` property which you can use to look up the task
later.

  --data '{"name": "setParameterValues", "parameterValues": [["InternetGatewayDevice.ManagementServer.UpgradesManaged",false]]}'

Multiple values can be set at once by adding multiple arrays to the
parameterValues key. For example:

  {
    name: "setParameterValues",
    parameterValues: [["InternetGatewayDevice.ManagementServer.UpgradesManaged", false], ["InternetGatewayDevice.Time.Enable", true], ["InternetGatewayDevice.Time.NTPServer1", "pool.ntp.org"]]

  -X POST \
  --data '{"name": "download", "file": "mipsbe-6-42-lite.xml"}'

.. _presets:

Presets
-------

Presets assign a set of configuration or a Provision script to devices based on
a precondition (search filter), schedule (cron expression), and events.

Precondition
~~~~~~~~~~~~

The ``precondition`` property is a JSON string representation of the search
filter to test if the preset applies to a given device. Examples preconditions
are:

- ``{"param": "value"}``
- ``{"param": value", "param2": {"$ne": "value2"}}``

Other operators that can be used are ``$gt``, ``$lt``, ``$gte`` and ``$lte``.

Configuration
~~~~~~~~~~~~~

The configuration property is an array containing the different configurations
to be applied to a device, as shown below:

.. code:: javascript

  [
    {
      "type": "value",
      "name": "InternetGatewayDevice.ManagementServer.PeriodicInformEnable",
      "value": "true"
    },
    {
      "type": "value",
      "name": "InternetGatewayDevice.ManagementServer.PeriodicInformInterval",
      "value": "300"
    },
    {
      "type": "delete_object",
      "name": "object_parent",
      "object": "object_name"
    },
    {
      "type": "add_object",
      "name": "object_parent",
      "object": "object_name"
    },
    {
      "type": "provision",
      "name": "YourProvisionName"
    },
  ] 

The configuration type ``provision`` triggers a Provision script. In the
example above, the provision named "YourProvisionName" will be executed.

Provisions
----------

Create a provision
~~~~~~~~~~~~~~~~~~

The Provision's JavaScript code is the body of the HTTP PUT request.

.. code:: bash

  curl -X PUT -i 'http://localhost:7557/provisions/mynewprovision' --data 'log("Provision started at " + now);'

Delete a provision
~~~~~~~~~~~~~~~~~~

.. code:: bash

  curl -X DELETE -i 'http://localhost:7557/provisions/mynewprovision'

Get provisions
~~~~~~~~~~~~~~

Get all provisions:

.. code:: bash

  curl -X GET -i 'http://localhost:7557/provisions/'
