Building Tools

Performing other tasks in circuits.web such as filtering requests and logging are fairly trivial. Here are some examples of other tasks you might perform in a web application.

Logging

Basic logging can easily be performed by implementing a Logger Component that simply prints the response before it's sent to the client (''The Browser'').

Example: ```

!python

!/usr/bin/env python

from circuits import Component from circuits.web import Server, Controller

class Logger(Component):

def response(self, response):
    print response

class Root(Controller):

def index(self):
    return "Hello World!"

(Server(8000) + Root() + Logger()).run() ```

This works be creating and adding a new Component into the system called Logger which contains 1 Event Handler. The Event Handler listens for Response events on the "response" channel. When it receives such an event, it simply prints the response object containing the response to be sent to the client (''The Browser'').
