Python select简单实现socket服务器的方法，pythonsocket,编橙之家本文为大家提供了

编橙之家本文为大家提供了关于Python select简单实现socket服务器的方法源码示例。源码编写借鉴了asyncore模块中select.select的使用方法，并使用了Python的socket、traceback和select模块方法。

什么是socket服务器？Socket服务器主要用于提供高效及稳定的数据信息处理，和消息的转发等服务。socket服务器直接决定了前台应用程序的性能。

Python select简单实现socket服务器的方法源码如下：

#导入方法模块import socketimport tracebackimport selectEOL1 = b'\n\n'EOL2 = b'\n\r\n'socketmap = {}r,w,e = [],[],[]response  = b'HTTP/1.0 200 OK\r\nDate: Mon, 1 Jan 1996 01:01:01 GMT\r\n'response += b'Content-Type: text/plain\r\nContent-Length: 13\r\n\r\n'response += b'Hello, world!'serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)serversocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)serversocket.bind(('0.0.0.0', 23456))serversocket.listen(1)#serversocket.setblocking(0)#www.iplaypy.comlistening_fileno = serversocket.fileno()socketmap[listening_fileno] = serversocketprint 'listening_fileno',listening_filenotry:    while True:        r,w,e = [],[],[]        for fd in socketmap:            r.append(fd)            w.append(fd)            e.append(fd)        r,w,e = select.select(r,w,e,1)        for fd in r:            request = b''            isocket = socketmap[fd]            if fd == listening_fileno:                print 'accepting'                clientsock,clientaddr = isocket.accept()                #clientsock.setblocking(0)                cli_fileno = clientsock.fileno()                r.append(cli_fileno)                w.append(cli_fileno)                e.append(cli_fileno)                socketmap[cli_fileno] = clientsock            else:                print 'reading'                while EOL1 not in request and EOL2 not in request:                    request += isocket.recv(1024)                print(request.decode())        for fd in w:            print 'writing'            osocket = socketmap[fd]            osocket.send(response)                    for fd in e:            esocket = socketmap[fd]            print 'socket close',fd            esocket.close()            del socketmap[fd]        print "no data coming"except Exception,e:    print traceback.print_exc()    serversocket.close()

注意：以上Python源码首要一定要加上编码声明，这是一个好的编程习惯。
