Question

Below you will find the skeleton code for the Web server. You are to complete the skeleton code or build your own code. In the skeleton code, the places where you need to fill in code are marked with #Fill. Each place may require one or more lines of code. (You may need to add additional lines other than the places marked with #Fill. The following just provides an example, you may not follow the example)

Skeleton Python Code for the Web Server

#import socket module

from socket import *

serverSocket = socket(AF_INET, SOCK_STREAM)

#Prepare a sever socket

#Fill

while True:

     #Establish the connection

     print 'Ready to serve...'

connectionSocket, addr = #Fill

try:

           message = #Fill nd

           filename = message.split()[1]

           f = open(filename[1:])

           outputdata = #Fill

           #Send one HTTP header line into socket

           #Fill

#Send the content of the requested file to the client

           for i in range(0, len(outputdata)):

                connectionSocket.send(outputdata[i])

           connectionSocket.close()

except IOError:

           #Send response message for file not found

           #Fill

           #Close client socket

           #Fill

serverSocket.close()

Explanation / Answer

#import socket module
from socket import *  
serverSocket = socket(AF_INET, SOCK_STREAM)
#Prepare a sever socket
serverSocket.bind(('127.0.0.1',80))
serverSocket.listen(5)
while True:
    #Establish the connection
    print 'Ready to serve...'
    (connectionSocket, addr) = serverSocket.accept()
    try:
        message = connectionSocket.recv(1024)
        filename = message.split()[1]
        f = open(filename[1:])
        outputdata = f.read()

        #Send one HTTP header line into socket
        connectionSocket.send('HTTP/1.1 200 OK ')

        #Send the content of the requested file to the client
        for i in range(0, len(outputdata)):
            connectionSocket.send(outputdata[i])
        connectionSocket.close()
    except IOError:
        #Send response message for file not found
        connectionSocket.send('file not found')
        #Close client socket
        connectionSocket.close()

serverSocket.close()
