HttpAuthenticated for WSDL open

[Ryan Schroeder]

Hello,

I have a server that requires basic HTTP authentication to download the WSDL
file.  I tried setting the transport to HTTPAuthenticated, but it looks like
the Client doesn't apply the options.transport when opening the url.

Here's the snippet I'm referring to from client.py:

    def __init__(self, url, **kwargs):
        """
        @param url: The URL for the WSDL.
        @type url: str
        @param kwargs: keyword arguments.
        @see: L{Options}
        """
        options = Options()
        options.transport = HttpAuthenticated()
        self.options = options
        options.cache = FileCache(days=1)
        self.set_options(**kwargs)
        self.wsdl = Definitions(url, options)           <--------------
shouldn't this be self.options?


I tried making this change, but also ran into the fact that the
HttpAuthenticated class does not override the open method using a provided
username and password.  The basic HttpTransport open method is called
instead.

Regards,

Ryan

Here's the open function for HttpAuthenticated.

class HttpAuthenticated(HttpTransport):
    """
    Provides basic http authentication for servers that don't follow
    the specified challenge / response model.  This implementation
    appends the I{Authorization} http header with base64 encoded
    credentials on every http request.
    """
    def open(self, request):
        credentials = self.credentials()
        theurl = request.url
        username = credentials[0]
        password = credentials[1]
        passman = u2.HTTPPasswordMgrWithDefaultRealm()
        passman.add_password(None, theurl, username, password)
        authhandler = u2.HTTPBasicAuthHandler(passman)
        opener = u2.build_opener(authhandler)
        u2.install_opener(opener)
        return HttpTransport.open(self, request)

Ryan: my setup is similar, and the normal c = Client(url, username =
'foo', password = 'bar') has always worked - could you send a sample
of your code?

As Matt has pointed out, this is the proper way to get the wsdl using http basic 
authentication.  The default transport already is HttpAuthenticated so you simply need to

pass the username and password in the Client constructor.

If this does not work then maybe your server does not implement RFC-2617 (as described 
here: http://en.wikipedia.org/wiki/Basic_access_authentication) properly in which case I 
can describe the workaround.
