Running an XML-RPC server with a basic HTTP authentication

Sometimes, you may need to implement authentication with an XML-RPC server. This recipe presents an example of a basic HTTP authentication with an XML-RPC server.

How to do it...

We can create a subclass of SimpleXMLRPCServer and override its request handler so that when a request comes, it is verified against given login credentials.

Listing 7.3a gives the code for running an XML-RPC server with a basic HTTP authentication, as shown:

#!/usr/bin/env python 
# Python Network Programming Cookbook, Second Edition -- Chapter - 7 
# This program is optimized for Python 3.5.2. 
# To make it work with Python 2.7.12: 
#      Follow through the code inline for some changes. 
# It may run on any other version with/without modifications. 
 
 
import argparse 
import xmlrpc 
# Comment out the above line and uncomment the below line for Python 2.x. 
#import xmlrpclib 
from base64 import b64decode 
 
from xmlrpc.server import SimpleXMLRPCServer, SimpleXMLRPCRequestHandler...
