The Evolution of Finger: Twisted client support using Perspective Broker

Introduction

This is the seventh part of the Twisted tutorial Twisted from Scratch, or The Evolution of Finger <index> .

In this part, we add a Perspective Broker service to the finger application so that Twisted clients can access the finger server. Perspective Broker is introduced in depth in its own section <core-howto-index-pb> of the core howto index.

Use Perspective Broker

We add support for perspective broker, Twisted's native remote object protocol. Now, Twisted clients will not have to go through XML-RPCish contortions to get information about users.

A simple client to test the perspective broker finger:
