python --------简单的socket通话实现例子

server 端代码

import socket

sk = socket.socket()  #买手机

sk.bind(('127.0.0.1',8080))  #绑定手机卡，跟着IP地址和端口号

sk.listen()                 #监听，   等着有人给我打电话

conn,addr = sk.accept()                 #接受到别人电话     connection 连接，address 地址（发件人的），
while True:
    ret = conn.recv(1024).decode('utf-8')
    if ret =='bye':
        conn.send(b'bye')
        break
    print(ret)
    info = input('>>>')
    conn.send(bytes(info,encoding='utf-8'))

    '''
    ret = conn.recv(1024)             #听别人说话，括号默认写1024的整数倍
    print(ret)
    
    conn.send(b'hi')                 #和别人说话，必须传一个bytes类型
    ret = conn.recv(1024)
    print(ret.decode('utf-8'))
    
    conn.send(bytes('大碗油泼面加个单',encoding='utf-8'))
    '''

conn.close()                    #挂电话

sk.close()                  #关手机

client端代码

import socket

sk = socket.socket()    #买手机
sk.connect(('127.0.0.1',8080))               #拨别人的号

while True:
    info = input('>>>')
    sk.send(bytes(info,encoding='utf-8'))
    ret = sk.recv(1024).decode('utf-8')
    print(ret)
    if ret == 'bye':
        sk.send(b'bye')
        break
    '''
    sk.send(b'hello')
    ret = sk.recv(1024)
    print(ret)
    sk.send(bytes('中午吃什么？'.encode('utf-8')))
    ret = sk.recv(1024)
    print(ret.decode('utf-8'))
    '''
sk.close()
