使用twisted實現Python用戶端

前面介紹了服務端架構,用戶端中的代碼可以複用其package.py和dispatch.py.

服務端方面一般是控制台運行,可是用戶端大部分都是帶ui的.

這裡分別介紹

1.console

用戶端啟動 main.py

這裡的PyConfigure不做介紹

from config import *from tcp import *def main():#[0] load configure json    cfg = PyConfigure( "cfg.json" )    host = cfg.get_value( "host" )    port = cfg.get_value( "port" )#[1] connect server    factory = PyClientFactory()    try:        reactor.connectTCP( host, port, factory )        reactor.run()    except:        print "connect server error."if __name__ == '__main__':    main()

用戶端實現 tcp.py

from twisted.internet.protocol import ClientFactory, Protocolfrom twisted.protocols.basic import LineReceiverfrom twisted.internet import reactorfrom twisted.internet.endpoints import TCP4ClientEndpointimport sysimport structfrom dispatch import *class PyTcpClient( Protocol ):    def __init__( self ):        self.dispatcher = PyDispatcher( self )    def connectionMade( self ):        print "login"    def connectionLost( self, reason ):        print "connection lost"    def dataReceived( self, data ):        print "receive:", data        self.dispatcher.dispatch( data )    def dataSend( self, data ):        print data        self.transport.write( data )class PyClientFactory( ClientFactory ):    protocol = PyTcpClient    def clientConnectionFailed( self, connector, reason ):        print 'connection failed:', reason.getErrorMessage()        reactor.stop()    def clientConnectionLost( self, connector, reason ):        print 'connection lost:', reason.getErrorMessage()        reactor.stop()

ok,這樣就可以工作了.不過代碼不夠簡潔.
2.ui

其實比較簡單:把

reactor.run()

放到線程裡面.

在下面結合pyQT4給出具體代碼.
