一个服务端，一个客户端，而且是阻塞方式，一次只能接受一个客户端连接并通信噢。
客户端发送‘bye', 结束与服务端的通信，如果发送'shutdown'，服务端将会关闭自己！
服务端代码:
from socket import * from time import ctime HOST='' PORT=21567 BUFSIZE=1024 ADDR=(HOST, PORT) tcpSerSock=socket(AF_INET, SOCK_STREAM) tcpSerSock.bind(ADDR) tcpSerSock.listen(5) quit=False shutdown=False while True: print('waiting for connection...') tcpCliSock, addr=tcpSerSock.accept() print('...connected from: ', addr) while True: data=tcpCliSock.recv(BUFSIZE) data=data.decode('utf8') if not data: break ss='[%s] %s' %(ctime(), data) tcpCliSock.send(ss.encode('utf8')) print(ss) if data=='bye': quit=True break elif data=='shutdown': shutdown=True break print('Bye-bye: [%s: %d]' %(addr[0], addr[1])) tcpCliSock.close() if shutdown: break tcpSerSock.close() print('Server has been
客户端代码:
from socket import * HOST='localhost' PORT=21567 BUFSIZE=1024 ADDR=(HOST, PORT) tcpCliSock=socket(AF_INET, SOCK_STREAM) tcpCliSock.connect(ADDR) while True: data=input('>') if not data: continue print('input data: [%s]' %data) tcpCliSock.send(data.encode('utf8')) rdata=tcpCliSock.recv(BUFSIZE) if not rdata: break print(rdata.decode('utf8')) if data=='bye' or data=='shutdown': break tcpCliSock.close()
