Servidor via terminal:
import socket from socket import * import sys import json serverPort = 3334 serverName = "WebServer" serverSocket = socket(AF_INET, SOCK_STREAM) serverSocket.bind(('localhost',serverPort)) serverSocket.listen(1) KBYTE = 1024 while True: try: connectionSocket, addr = serverSocket.accept() message = connectionSocket.recv(KBYTE).decode() filename = message.split('/')[-1] with open(filename, 'r') as file: outputdata = file.readlines() connectionSocket.send('status 200 Ok'.encode()) for item in outputdata: connectionSocket.send(item.encode()) connectionSocket.send("\r\n".encode()) connectionSocket.close() except FileNotFoundError as e: response = '404 file not found'.encode() connectionSocket.send(response) connectionSocket.close() break serverSocket.close() sys.exit()

Client via terminal:
from socket import * host = 'localhost' port = 3334 clientSocket = socket(AF_INET, SOCK_STREAM) clientSocket.connect((host, port)) message = input('Your message: ') url = f"http://{host}:{port}/{message}" clientSocket.send(url.encode()) modifiedSentence = clientSocket.recv(1024) clientSocket.close()
