python学习笔记(51) socketsever和看源码

第一：整理多个类之间的继承关系

第二：列出每一个类的方法

第三：清楚了解所有self对象调用到底是谁的对象

第四：所有方法调用要退回到最子类开始寻找，逐级向上

 

SEVER:

import socketserver


class MyServer(socketserver.BaseRequestHandler):
    def handle(self):
        while 1:         # self.request相当于一个conn
            msg = self.request.recv(1024).decode('utf-8')
            if msg == 'q':
                self.request.send(b'q')
                break
            print(msg)
            info = input('>>>')
            self.request.send(info.encode('utf-8'))



if __name__ == '__main__':
    sever = socketserver.ThreadingTCPServer(('127.0.0.1',8090),MyServer)
    sever.serve_forever()

CLIENT1:

import socket
sk = socket.socket()
sk.connect(('127.0.0.1',8090))
while 1:
    msg = input('>>>')
    if msg == 'q':
        sk.send(b'q')
        break
    sk.send(('美团：'+msg).encode('utf-8'))
    ret = sk.recv(1024).decode('utf-8')
    if ret == 'q':
        break
    print(ret)

sk.close()

CLIENT2:

import socket
sk = socket.socket()
sk.connect(('127.0.0.1',8090))
while 1:
    msg = input('>>>')
    if msg == 'q':
        sk.send(b'q')
        break
    sk.send(('饿了么：'+msg).encode('utf-8'))
    ret = sk.recv(1024).decode('utf-8')
    if ret == 'q':
        break
    print(ret)

sk.close()
