day32-socketserver

#socketserver 是在socket基础上进行了封装，它让server可以实时跟多个client进行通信。
#thread线程：一个程序有一个线程，一个线程是调度cpu的最小单位。程序运行才产生线程，不运行就不产生。
#如果启用多个线程去接收多个client的请求，就能实现并发的效果。

# server:
import socketserver
class MyServer(socketserver.BaseRequestHandler):  #必须继承此父类
    def handle(self):                             #必须定义此函数,self.request相当于conn
        while True:
            msg = self.request.recv(1024).decode('utf-8')
            print(msg)
            if msg == 'q':
                break
            info = input('server:')
            self.request.send(info.encode('utf-8'))
