6주차_Network : 소켓 실습

 

몇주간에 걸쳐서 네트워크에 대하여 학습했다.

마무리로 우리 조는 함께 모여 소켓 실습을 진행했다.

 

📌실습 내용

 

[소켓]

from socket import *

serverSock = socket(AF_INET, SOCK_STREAM)
serverSock.bind(('127.0.0.1', 8080))
serverSock.listen(1) 


connectionSock, addr = serverSock.accept()

print(str(addr), 'access')

data = connectionSock.recv(1024)
print("data:", data.decode('utf-8'))

connectionSock.send('I am server.'.encode('utf-8'))
print('메시지를 전송하였습니다.')

 

from socket import *

ClientSock = socket(AF_INET, SOCK_STREAM)
ClientSock.connect(('127.0.0.1', 8080))

print('연결이 확인 되었습니다.')
ClientSock.send('I am client'.encode('utf-8'))

print('메시지를 전송하였습니다.')

data = ClientSock.recv(1024)
print('data: ', data.decode('utf-8'))
