This is a simple chat application using socket programming in Python. It consists of a server and client that can communicate with each other.
It contains the following files:
- server.py - The server code
- client1.py - The client code
Key features:
- Creates a socket and binds it to localhost and port 12345
- Listens for incoming connections in a loop
- For each client, creates a thread to handle sending and receiving of messages
- Maintains a dictionary of client connections
- Broadcasts messages from one client to all other connected clients
- Closes client sockets gracefully on disconnect
Key features:
- Creates a socket and connects to the server
- Sends messages to the server by taking user input
- Receives messages from the server and prints them
- Cleanly closes socket on exiting
To run the application:
- Start the server:
python server.py
To start the server:
python server.py
This will start the server on localhost port 12345.
- Open another terminal and run the client:
python client1.py
To start the client:
python client.py
This will connect the client to the running server.
Multiple clients can connect to the same server. Each client connection will be handled in a separate thread.
- Send messages from the client and observe the communication.
- Type 'exit' on the client to disconnect gracefully.
The server has the following capabilities:
- Accept connections from multiple clients
- Receive and send messages to each connected client
- Broadcast messages from one client to all others
- Gracefully handle client disconnections
The main components are:
- Socket creation and binding
- Listening for connections in a loop
- Spawning a thread per client to handle all communication
- Cleaning up threads when clients disconnect
The client can:
- Connect to the server
- Send messages to the server
- Receive messages from the server
- Gracefully handle disconnection
The key components are:
- Socket creation and connection
- Threads for sending and receiving messages
- Clean shutdown on disconnect
Some of the key aspects of message handling are:
- Prefixing messages with client name
- Detecting client disconnects by empty recv
- Broadcast by looping through all connected clients
- The server handles each client connection in a separate thread.
- When a client sends a message, it is broadcast to all other clients.
- The main threads handle sending and receiving messages independently.
This allows building a simple chat application using socket programming concepts.
