uPnPclient

uPnP client library for Python 3.

This library can be used to discover and consume uPnP devices and their services.

It's originally based on Ferry Boender's work and his blog post entitled Exploring UPnP with Python.

Installation

pip install upnpclient

Usage

Typical usage:

In [1]: import upnpclient

In [2]: devices = upnpclient.discover()

In [3]: devices
Out[3]: 
[<Device 'OpenWRT router'>,
 <Device 'Harmony Hub'>,
 <Device 'walternate: root'>]

In [4]: d = devices[0]

In [5]: d.WANIPConn1.GetStatusInfo()
Out[5]: 
{'NewConnectionStatus': 'Connected',
 'NewLastConnectionError': 'ERROR_NONE',
 'NewUptime': 14851479}

In [6]: d.WANIPConn1.GetNATRSIPStatus()
Out[6]: {'NewNATEnabled': True, 'NewRSIPAvailable': False}

In [7]: d.WANIPConn1.GetExternalIPAddress()
Out[7]: {'NewExternalIPAddress': '123.123.123.123'}

If you know the URL for the device description XML, you can access it directly.

In [1]: import upnpclient

In [2]: d = upnpclient.Device("http://192.168.1.1:5000/rootDesc.xml")

In [3]: d.services
Out[3]: 
[<Service service_id='urn:upnp-org:serviceId:Layer3Forwarding1'>,
 <Service service_id='urn:upnp-org:serviceId:WANCommonIFC1'>,
 <Service service_id='urn:upnp-org:serviceId:WANIPConn1'>]

In [4]: d.Layer3Forwarding1.actions
Out[4]: 
[<Action 'SetDefaultConnectionService'>,
 <Action 'GetDefaultConnectionService'>]

In [5]: d.Layer3Forwarding1.GetDefaultConnectionService()
Out[5]: {'NewDefaultConnectionService': 'uuid:46cb370a-d7f2-490f-ac01-fb0db6c8b22b:WANConnectionDevice:1,urn:upnp-org:serviceId:WANIPConn1'}

Sometimes the service or action name isn't a valid property name. In which case, service and actions can be accessed other ways:

In [1]: d["Layer3Forwarding1"]["GetDefaultConnectionService"]()
Out[1]: {'NewDefaultConnectionService': 'uuid:46cb370a-d7f2-490f-ac01-fb0db6c8b22b:WANConnectionDevice:1,urn:upnp-org:serviceId:WANIPConn1'}

To view the arguments required to call a given action:

In [1]: d.WANIPConn1.AddPortMapping.argsdef_in
Out[1]: 
[('NewRemoteHost',
  {'allowed_values': set(), 'datatype': 'string', 'name': 'RemoteHost'}),
 ('NewExternalPort',
  {'allowed_values': set(), 'datatype': 'ui2', 'name': 'ExternalPort'}),
 ('NewProtocol',
  {'allowed_values': {'TCP', 'UDP'},
   'datatype': 'string',
   'name': 'PortMappingProtocol'}),
 ('NewInternalPort',
  {'allowed_values': set(), 'datatype': 'ui2', 'name': 'InternalPort'}),
 ('NewInternalClient',
  {'allowed_values': set(), 'datatype': 'string', 'name': 'InternalClient'}),
 ('NewEnabled',
  {'allowed_values': set(),
   'datatype': 'boolean',
   'name': 'PortMappingEnabled'}),
 ('NewPortMappingDescription',
  {'allowed_values': set(),
   'datatype': 'string',
   'name': 'PortMappingDescription'}),
 ('NewLeaseDuration',
  {'allowed_values': set(),
   'datatype': 'ui4',
   'name': 'PortMappingLeaseDuration'})]

and then to call the action using those arguments:

In [1]: d.WANIPConn1.AddPortMapping(
   ...:     NewRemoteHost='0.0.0.0',
   ...:     NewExternalPort=12345,
   ...:     NewProtocol='TCP',
   ...:     NewInternalPort=12345,
   ...:     NewInternalClient='192.168.1.10',
   ...:     NewEnabled='1',
   ...:     NewPortMappingDescription='Testing',
   ...:     NewLeaseDuration=10000)
Out[1]: {}

Similarly, the arguments you can expect to receive in response are listed:

In [1]: d.WANIPConn1.GetGenericPortMappingEntry.argsdef_out
Out[1]: 
[('NewRemoteHost',
  {'allowed_values': set(), 'datatype': 'string', 'name': 'RemoteHost'}),
 ('NewExternalPort',
  {'allowed_values': set(), 'datatype': 'ui2', 'name': 'ExternalPort'}),
 ('NewProtocol',
  {'allowed_values': {'TCP', 'UDP'},
   'datatype': 'string',
   'name': 'PortMappingProtocol'}),
 ('NewInternalPort',
  {'allowed_values': set(), 'datatype': 'ui2', 'name': 'InternalPort'}),
 ('NewInternalClient',
  {'allowed_values': set(), 'datatype': 'string', 'name': 'InternalClient'}),
 ('NewEnabled',
  {'allowed_values': set(),
   'datatype': 'boolean',
   'name': 'PortMappingEnabled'}),
 ('NewPortMappingDescription',
  {'allowed_values': set(),
   'datatype': 'string',
   'name': 'PortMappingDescription'}),
 ('NewLeaseDuration',
  {'allowed_values': set(),
   'datatype': 'ui4',
   'name': 'PortMappingLeaseDuration'})]

HTTP Auth/Headers

You may pass a requests compatible authentication object and/or a dictionary containing headers to use on the HTTP calls to your uPnP device.

These may be set on the Device itself on creation for use with every HTTP call:

device = upnpclient.Device(
    "http://192.168.1.1:5000/rootDesc.xml"
    http_auth=('myusername', 'mypassword'),
    http_headers={'Some-Required-Header': 'somevalue'}
)

Or on a per-call basis:

device.Layer3Forwarding1.GetDefaultConnectionService(
    http_auth=('myusername', 'mypassword'),
    http_headers={'Some-Required-Header': 'somevalue'}
)

If you've set either at Device level, they can be overridden per-call by setting them to None.
