Socket Programming Assignment: Web Server
Socket Programming Assignment: Web Server (page 181)
In this lab, you will learn the basics of socket programming for TCP connections in Python: how to create a socket, bind it to a specific address and port, as well as send and receive a HTTP packet. You
will also learn some basics of HTTP header format. You will develop a web server that handles one HTTP request at a time. Your web server should accept and parse the HTTP request, get the
requested file from the server’s file system, create an HTTP response message consisting of the requested file preceded by header lines, and then send the response directly to the client. If the
requested file is not present in the server, the server should send an HTTP “404 Not Found” message back to the client.
Code
Below you will find the skeleton code for the Web server. You are to complete the skeleton code. The places where you need to fill in code are marked with #Fill in start and #Fill in end. Each place may require one or more lines of code.
Running the Server
Socket Programming Assignment
Put an HTML file (e.g., HelloWorld.html) in the same directory that the server is in. Run the server program. Determine the IP address of the host that is running the server (e.g., 128.238.251.26). From
another host or the same host if you run the server on the local manchine, open a browser and provide the corresponding URL. For example: http://128.238.251.26:6789/HelloWorld.html
‘HelloWorld.html’ is the name of the file you placed in the server directory. Note also the use of the port number after the colon. You need to replace this port number with whatever port you have used in the server code. In the above example, we have used the port number 6789. The browser should then display the contents of HelloWorld.html. If you omit “:6789”, the browser will assume port 80 and you will get the web page from the server only if your server is listening at port 80.
You can also run the server program on your own PC and access the webserver from the same PC using the IP address for local host (127.0.0.1). For example: http://127.0.0.1:6789/HelloWorld.html
Then try to get a file that is not present at the server. You should get a “404 Not Found” message.
What to Hand in
You will hand in the complete server code (a .py file) along with the screen shots of your client browser, verifying that you actually receive the contents of the HTML file from the server.
Skeleton Python Code for the Web Server (Use the code in the skeleton.py file as the skeleton of your .py file and insert lines of code needed between #Fill in state and #Fill in end. Please note that Python programs get structured through indentation, copy and paste may change the indentation of the following lines. You are suggested to use Python 3.x.
