In this tutorial, we will explore how to create a simple HTTP server using Python's built-in http.server module. We'll focus on creating a custom request handler to handle incoming HTTP requests.
Make sure you have Python installed on your machine. This tutorial is based on Python 3.x.
First, let's import the necessary modules.
Now, let's create a custom request handler by subclassing BaseHTTPRequestHandler. We'll override the do_GET method to handle GET requests.
In this example, the do_GET method is called whenever a GET request is received. It sends a response with a 200 status code, sets the content type to 'text/html', and extracts the value of the 'name' parameter from the query string.
Now, let's create an instance of the HTTP server with our custom request handler and run it.
This code creates an instance of the HTTP server on the specified port (default is 8000) and prints a message indicating that the server is running. The serve_forever method starts the server and keeps it running until interrupted.
Save the code in a file (e.g., custom_server.py) and run it from the command line:
Open your web browser and visit http://localhost:8000/?name=John. You should see a page that says "Hello, John".
Congratulations! You've created a simple Python HTTP server with a custom request handler. You can extend this example to handle other HTTP methods, headers, and more based on your specific requirements.
