Python学习之路：socket简单实例

客户端

#客户端
import socket

client = socket.socket()#相当于声明socket类型，同时生成socket连接对象
client.connect(('localhost',6969))

client.send(b"Hello World!")
data = client.recv(1024)
print("recv:",data)

client.close()

服务端

#服务器端
import socket

server = socket.socket()
server.bind(("localhost",6969))#绑定要监听的端口
server.listen()#监听

print("我要开始等电话了")

conn,addr = server.accept()#等电话打进来
print(conn,addr)

print("电话来了")

data = conn.recv(1024)
print("recv:",data)
conn.send(data.upper())

server.close()
