This repo provides examples of basic networking operations using Python. It includes implementations for TCP communication using sockets and making HTTP requests.

  1. Socket Communication: Demonstrates how to create a simple TCP server and client using Python's socket library.
  2. HTTP Requests: Shows how to perform HTTP GET and POST requests using the requests library.

Files

1. Socket Communication (sockets.py)

Description

This script contains two main functions:

  • start_server(host='localhost', port=65432): Starts a TCP server that listens on the specified host and port. The server echoes back any data it receives from clients.
  • start_client(host='localhost', port=65432, message='Hello, World!'): Connects to a TCP server at the specified host and port, sends a message, and prints the response from the server.

How to Use

  1. Run the Server:

    • Open a terminal and execute the script to start the server: 
      python sockets.py
    • The server will start and listen for incoming connections.

  2. Run the Client:

    • The client is automatically started by the script after the server starts. It will connect to the server, send a message, and print the server's response.

Example Output

Server listening on localhost:65432
Connected by ('127.0.0.1', 54321)
Received: Hello, World!
Received from server: Hello, World!

2. HTTP Requests (http_requests.py)

Description

This script demonstrates how to perform HTTP requests using the requests library:

  • make_get_request(url): Makes a GET request to the specified url and prints the status code and response text.
  • make_post_request(url, data): Makes a POST request to the specified url with the given data and prints the status code and response text.

How to Use

  1. Ensure a Local Server is Running:

    • You need a server running on http://localhost:8000. You can use Python's built-in HTTP server for testing: 
      python -m http.server 8000

  2. Run the Script:

    • Execute the script to perform GET and POST requests: 
      python http_requests.py

Example Output

Making GET request to http://localhost:8000
Status Code: 200
Response Text: (Response from the local server)

Making POST request to http://localhost:8000 with data {'key': 'value'}
Status Code: 200
Response Text: (Response from the local server)
