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

serverSocket.close()

Explanation / Answer

#import socket module

from socket import *

serverSocket= socket(AF_INET, SOCK_STREAM)#creates socket

#Prepare a sever socket

#Fill

serverPort = 7000 #sets port

serverSocket.bind((”, serverPort)) #associates socket with this port

serverSocket.listen(1) #tells socket to listen for requests

#Fill

while True:

#Establish the connection

print ‘Ready to serve…’

connectionSocket, addr = serverSocket.accept() #creates a socket specifically for this client

try:

message =connectionSocket.recv(1024) #receives message from client

print message

filename = message.split()[1]

f = open(filename[1:]) #opens file and reads the contents

outputdata =f.read()

#Send one HTTP header line into socket

#Fill

connectionSocket.send(‘ HTTP/1.x 200 OK ’) #sends a 200 OK header line

#Fill

#Send the content of the requested file to the client

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

connectionSocket.send(outputdata[i]) #outputs all of the data in the file

connectionSocket.close() #closes the socket for this client

print ‘File Recieved’

except IOError:

#Sendresponse message for file not found

#Fill

connectionSocket.send(‘ 404 File Not Found ’) #sends an error message to be printed on the page

#Fill

#Close client socket

#Fill

connectionSocket.close() #closes the socket for the client

#Fill

serverSocket.close() #closes the server socket
