Well first of all I think rolling out your own solution for this all you need is urllib2 or httplib2 . Anyways in case you do require a generic REST client check this out .

However i think the feature set of the library will not work for most web services because they shall probably using oauth etc .. . Also I don't like the fact that it is written over httplib which is a pain as compared to httplib2 still should work for you if you don't have to handle a lot of redirections etc ..

You basically need to make a HTTP request to the service  and then parse the body of the response  I like to use httplib2 for it   import httplib2 as http import json  try      from urlparse import urlparse except ImportError      from urllib parse import urlparse  headers          Accept    application json        Content-Type    application json  charset UTF-8     uri    http   yourservice com  path     path to resource    target   urlparse uri path  method    GET  body       h   http Http      If you need authentication some example  if auth      h add credentials auth user  auth password   response  content   h request          target geturl            method          body          headers     assume that content is a json reply   parse content with the json module data   json loads content

Something like this should work unless I m missing the point   import json import urllib2 json load urllib2 urlopen  url

I would give the requests library a try for this  Essentially just a much easier to use wrapper around the standard library modules  i e  urllib2  httplib2  etc   you would use for the same thing  For example  to fetch json data from a url that requires basic authentication would look like this   import requests  response   requests get  http   thedataishere com                            auth   user    password    data   response json     For kerberos authentication the requests project has the reqests-kerberos library which provides a kerberos authentication class that you can use with requests   import requests from requests kerberos import HTTPKerberosAuth  response   requests get  http   thedataishere com                            auth HTTPKerberosAuth    data   response json

If you desire to use Python 3  you can use the following   import json import urllib request req   urllib request Request  url   with urllib request urlopen req  as response      result   json loads response readall   decode  utf-8
