pyupnp-async 0.1.1.1

Python Library for UPnP operations using asyncio

A Python library for UPnP operations using asyncio.

Currently this library only provided convenience for port forwarding using UPnP. For other UPnP features, it is possible, but manual construction of request parameters is needed. (I.E. the SOUP request XML.)

Installation

To install the latest development version, run:

git clone https://github.com/xinhuang/pyupnp-async.git
cd pyupnp-async
python setup.py install

This package is not on pypi.

Quick Tutorial

Create a port forwarding using UPnP:

from pyupnp_async import msearch_first

async def forward_port(local_ip, local_port, ext_port, protocol):
    resp = await msearch_first('urn:schemas-upnp-org:device:InternetGatewayDevice:1')
    device = await resp.get_device()
    service = device.find_first_service('urn:schemas-upnp-org:service:WANIPConnection:1')
    ext_ip = await service.get_external_ip_address()
    try:
        await service.add_port_mapping(local_port, ext_port, local_ip, protocol)
        print('Data to external Port {} will be forwarded to {}:{}'.format(ext_port, local_ip, local_port))
    except UpnpSoapError as e:
        print(e)

Delete a port forwarding using UPnP:

from pyupnp_async import msearch_first

async def stop_forwarding(ext_port, protocol):
    resp = await msearch_first('urn:schemas-upnp-org:device:InternetGatewayDevice:1')
    device = await resp.get_device()
    service = device.find_first_service('urn:schemas-upnp-org:service:WANIPConnection:1')
    ext_ip = await service.get_external_ip_address()
    try:
        await service.delete_port_mapping(ext_port, protocol)
        print('Data to external Port {} will not be forwarded any more.')
    except UpnpSoapError as e:
        print(e)

API Reference

msearch_first(search_target='upnp:rootdevice', max_wait=2, loop=None)

Searches for UPnP target specified, and returns the first responsed target.

Args:

• search_target: Search target. For details please reference to UPnP spec.

• max_wait: Specify max waiting time in seconds.

• loop: Specify the event loop to be used. Default is asyncio.get_event_loop()

msearch_first(search_target='upnp:rootdevice', max_wait=2, loop=None)

Searches for UPnP target specified, and returns all targets responded in given time range as an async iterator.

Args:

• search_target: Search target. For details please reference to UPnP spec.

• max_wait: Specify max waiting time in seconds.

• loop: Specify the event loop to be used. Default is asyncio.get_event_loop()
