网络编程 - socket通信/粘包/文件传输/udp - 总结

socket通信

1.简单的套接字通信

 1 import socket
 2 phone = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 3 phone.bind(('127.0.0.1',8080))
 4 phone.listen(5)
 5 print('starting...')
 6 conn,client_addr = phone.accept()
 7 data = conn.recv(1024)
 8 conn.send(data.upper())
 9 conn.close()
10 phone.close()
