[转]Python使用TCPServer编写（多线程）Socke

【转】https://blog.csdn.net/ghostfromheaven/article/details/8653421#

SocketServer包对socket包进行了包装（封装），使得创建socket服务非常简单。

TCPServer+BaseRequestHandler

使用TCPServer和BaseRequestHandler编写socket服务的样例。

#-*- coding:utf-8 -*-

from SocketServer import TCPServer, BaseRequestHandler

import traceback

class MyBaseRequestHandlerr(BaseRequestHandler):

    """

    #从BaseRequestHandler继承，并重写handle方法

    """

    def handle(self):

        #循环监听（读取）来自客户端的数据

        while True:

            #当客户端主动断开连接时，self.recv(1024)会抛出异常

            try:

                #一次读取1024字节,并去除两端的空白字符(包括空格,TAB,\r,\n)

                data = self.request.recv(1024).strip()



                #self.client_address是客户端的连接(host, port)的元组

                print "receive from (%r):%r" % (self.client_address, data)



                #转换成大写后写回(发生到)客户端

                self.request.sendall(data.upper())

            except:

                traceback.print_exc()

                break

if __name__ == "__main__":

    #telnet 127.0.0.1 9999

    host = ""      #主机名，可以是ip,像localhost的主机名,或""

    port = 9999    #端口

    addr = (host, port)



    #购置TCPServer对象，

    server = TCPServer(addr, MyBaseRequestHandlerr)



    #启动服务监听

    server.serve_forever()

TCPServer+StreamRequestHandler

使用TCPServer和StreamRequestHandler编写socket服务的样例。StreamRequestHandler从BaseRequestHandler，并做了封装，使得读写数据更容易。

#-*- coding:utf-8 -*-

from SocketServer import TCPServer, StreamRequestHandler

import traceback

class MyStreamRequestHandlerr(StreamRequestHandler):

    """

    #继承StreamRequestHandler，并重写handle方法

    #（StreamRequestHandler继承自BaseRequestHandler）

    """

    def handle(self):

        while True:

            #客户端主动断开连接时，self.rfile.readline()会抛出异常

            try:

                #self.rfile类型是socket._fileobject,读写模式是"rb",方法有

                #read,readline,readlines,write(data),writelines(list),close,flush

                data = self.rfile.readline().strip()

                print "receive from (%r):%r" % (self.client_address, data)



                #self.wfile类型是socket._fileobject,读写模式是"wb"

                self.wfile.write(data.upper())

            except:

                traceback.print_exc()

                break

if __name__ == "__main__":

    host = ""      #主机名，可以是ip,像localhost的主机名,或""

    port = 9999    #端口

    addr = (host, port)



    server = TCPServer(addr, MyStreamRequestHandlerr)

    server.serve_forever()

ThreadingTCPServer+StreamRequestHandler=多线程socket

使用ThreadingTCPServer和StreamRequestHandler编写socket服务的样例。ThreadingTCPServer从ThreadingMixIn和TCPServer继承，实现多线程。

#-*- coding:utf-8 -*-

from SocketServer import ThreadingTCPServer, StreamRequestHandler

import traceback

class MyStreamRequestHandlerr(StreamRequestHandler):

    def handle(self):

        while True:

            try:

                data = self.rfile.readline().strip()

                print "receive from (%r):%r" % (self.client_address, data)

                self.wfile.write(data.upper())

            except:

                traceback.print_exc()

                break

if __name__ == "__main__":

    host = ""      #主机名，可以是ip,像localhost的主机名,或""

    port = 9999    #端口

    addr = (host, port)



    #ThreadingTCPServer从ThreadingMixIn和TCPServer继承

    #class ThreadingTCPServer(ThreadingMixIn, TCPServer): pass

    server = ThreadingTCPServer(addr, MyStreamRequestHandlerr)

    server.serve_forever()

多线程socket效果：
