WS-Discovery implementation for python

Project description

WS-Discovery in Python

This is WS-Discovery implementation for Python 2 & 3. It allows to both discover services and publish discoverable services.

Authors and maintaining

Original version created by L.A. Fernando. Code was then forked and maintained by Andrei Kopats. Python3 port done by Pieter Jordaan. Packaging, major refactoring & command-line client by Petri Savolainen. Python2 support fixes by Michael Leinartas.


A simple discover command-line client is provided for discovering WS-Discovery compliant devices and systems. Run discover --help for usage instructions.

Here's an example of how to use the package in your Python code. The following code first publishes a service and then discovers it:

    from wsdiscovery import WSDiscovery, QName, Scope

    wsd = WSDiscovery()

    ttype = QName("abc", "def")

    ttype1 = QName("namespace", "myTestService")

    # Note: some devices scope services using onvif:// scheme, not http://
    scope1 = Scope("http://myscope")
    ttype2 = QName("namespace", "myOtherTestService_type1")
    scope2 = Scope("http://other_scope")

    xAddr = "localhost:8080/abc"
    wsd.publishService(types=[ttype], scopes=[scope2], xAddrs=[xAddr])

    #ret = wsd.searchServices(scopes=[scope1], timeout=10)
    ret = wsd.searchServices()

    for service in ret:
        print(service.getEPR() + ":" + service.getXAddrs()[0])


Development state

This is not 100% complete and correct WS-Discovery implementation. It doesn't verify data received from the network. It may crash, and might contain security holes. No guarantees - test it carefully for your use case.
