先看socket多并发的服务端的代码,这里是用多线程实现的多并发socketserver

import socketserver


# socketserver有四个基本的类,后两个不常用,这4个类处理并发请求都是同步的,他们其实不是多线程的,他们只是把socke封装了一下,加了一些方法,这里还没有实现多并发和多线程
#这些方法不适用每个请求都耗费长时间才能完成


# socketserver.TCPServer
# socketserver.UDPServer
# socketserver.UnixStreamServer
# socketserver.UnixDatagramServer
# socketserver.ForkingMixIn
# socketserver.ThreadingMixIn

# ========================================================================================================
# 我们真正要用的下面这4个方法
# 多进程的socketserver
# socketserver.ForkingTCPServer
# socketserver.ForkingUDPServer

#多进程的socketserver
# socketserver.ThreadingTCPServer
# socketserver.ThreadingUDPServer


# ========================================================================================================


class MyTcpServerClass(socketserver.BaseRequestHandler):
    # 先定义一个自己的socket的类,所有和客户端交互的动作全部要在这里写,默认这里是空白的,且必须写handle这个防范
    def handle(self):
        print("等待新的连接:")
        print("新的客户端:",self.client_address)
        while True:
            try:
                data = self.request.recv(1024)
                print("客户端:",self.client_address,str(data,encoding="utf-8"))
                self.request.send(data)
            except Exception:
                print("客户端[%s]连接已经断开,服务端也将断开" %(self.client_address[1]))
                self.request.close()
                break

if __name__ == '__main__':
    ip_bind = ("127.0.0.1",9000)
    server = socketserver.ThreadingTCPServer(ip_bind,MyTcpServerClass)
    # 每次来一个连接,就构建一个实例
    server.serve_forever()
    # 让这个server一直运行

 

然后看下客户端的代码

import socket
ip_bind = ("127.0.0.1",9000)

c = socket.socket()
c.connect(ip_bind)
while True:
    c_input = input("客户端:")
    c.send(bytes(c_input,encoding="utf-8"))
    s_send = c.recv(1024)
    print("服务端:",str(s_send,encoding="utf-8"))
