Messaging System

Introduction

This project implements a simple messaging system with a server and client in Python. The system allows users to create accounts, send messages, and manage their inbox.

Prerequisites

• Python 3

Files

• server.py: Contains the implementation of the messaging server.
• client.py: Implements a client to interact with the messaging server.

Classes

Account

Represents a user account with a username and authentication token.

MessagingServer

Implements the messaging server, allowing account creation, message sending, and inbox management.

MessagingClient

A client interface to interact with the messaging server. Provides methods to create accounts, send messages, and manage the inbox.

Usage

Running the Server

1. Open a terminal.
2. Navigate to the directory containing Server.py.
3. To run the server, use the following command:

python server.py <port_number>

Replace <port_number> with the desired port.

Running the Server

1. Open a new terminal.
2. Navigate to the directory containing Client.py.
3. Run the following commands

• Create Account (Function ID: 1)

python client.py <server_ip> <server_port> 1 <username>

Creates an account for the user with the specified username and returns a unique authentication token.

• Show Accounts (Function ID: 2)

python client.py <server_ip> <server_port> 2 <authToken>

Displays a list of all accounts in the system.

• Send Message (Function ID: 3)

python client.py <server_ip> <server_port> 3 <authToken> <recipient> <message_body>

Sends a message to the specified recipient.

• Show Inbox (Function ID: 4)

python client.py <server_ip> <server_port> 4 <authToken>

Displays a list of all messages in the user's inbox.

• Read Message (Function ID: 5)

python client.py <server_ip> <server_port> 5 <authToken> <message_id>

Displays the content of a specific message and marks it as read.

• Delete Message (Function ID: 6)

python client.py <server_ip> <server_port> 6 <authToken> <message_id>

Deletes a specific message from the user's inbox.

Examples

Server

python server.py 5000

Client

Create Account

python client.py localhost 5000 1 demouser

Show Accounts

python client.py localhost 5000 2 <authToken>

Send Message

python client.py localhost 5000 3 <authToken> friend "Hello, friend!"

Show Inbox

python client.py localhost 5000 4 <authToken>

Read Message

python client.py localhost 5000 5 <authToken> 1

Delete Message

python client.py localhost 5000 6 <authToken> 1

Make sure to replace <server_ip>, <server_port>, <authToken>, <username>, <recipient>, <message_body>, and <message_id> with the appropriate values.

Notes

• Ensure that the server is running before attempting to use the client.
• The provided examples assume the server is running on localhost and port 5000. Adjust the parameters accordingly based on your setup.
