Re: [Xen-API] Diferences in Xen API languages bindings ou implementations?

[Jonathan Ludlam <Jonathan.Ludlam@xxxxxxxxxxxxx>]

Hi Erick,

XenAPI.py is a thin layer on top of the raw XMLRPC which hides some aspects of 
the session handling and error checking. I don't think it's documented anywhere 
as far as I know, so figuring out how to get some things to work involves 
looking at the source. I often use the standard 'xmlrpclib' module instead, 
which you might find is closer to the documented API.

For reference, here's how to call session.get_this_host using both libraries:

First, using XenAPI.py:

import XenAPI
session = XenAPI.Session("http://localhost/";)
session.login_with_password("root","myultrasecurepassword")
session.xenapi.session.get_this_host(session._session)


Secondly, using xmlrpclib:

import xmlrpclib
s=xmlrpclib.Server("http://localhost/";)
session_ref=s.session.login_with_password("root","myultrasecurepassword")['Value']
s.session.get_this_host(session_ref,session_ref)['Value']

Hope this helps!

Jon
