[PYTHON/COMMON] socket 클래스 : 단순 TCP 서버/클라이언트 만들기

icodebroker COMMON 2024-06-18

■ socket 클래스를 사용해 단순 TCP 서버/클라이언트를 만드는 방법을 보여준다.

▶ server.py


import json
import socket

def startServer(hostIPAddress, hosePort):
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as socket1:
        socket1.bind((hostIPAddress, hosePort))
        socket1.listen()

        print(f"클라이언트 요청 수신중 : {hostIPAddress}:{hosePort}")

        while True:
            socket2, clientAddress = socket1.accept()

            with socket2:
                print(f"클라이언트 연결 : {clientAddress}")

                while True:
                    receiveBytes = socket2.recv(1024)

                    if not receiveBytes:
                        break

                    receiveDictionary = json.loads(receiveBytes.decode())

                    print(f"수신 데이터 : {receiveDictionary}")

                    sendDictonary = {"status" : "success", "message" : "Data received"}

                    socket2.sendall(json.dumps(sendDictonary).encode())

            print(f"클라이언트 연결 종료 : {clientAddress}")

if __name__ == "__main__":
    startServer("127.0.0.1", 12345)
