如何编写Twisted客户端插件

Question

我曾经习惯twisted实现客户端.它工作正常.现在我希望能够将命令行参数传递给它,所以我需要实现一个twisted 插件.我已经执行了很多搜索来查找将显示如何将程序转换为插件的资源.但是我找不到我想要的东西.

这是我的client.py代码的相关部分:

import sys
import time
import os
import errno
import re
from stat import *
global runPath

runPath = '/home/a02/Desktop/'

from twisted.python import log
from GlobalVariables import *
from twisted.internet import reactor, threads, endpoints
from time import sleep
from twisted.internet.protocol import ClientFactory# , Protocol
from twisted.protocols import basic
import copy


class MyChat(basic.LineReceiver):
    def connectionMade(self):
        print "Connected to the server!"
        EchoClientFactory.buildClientObject(self.factory, self)
        self.runPythonCommands = RunPythonCommands ()
        return

    def connectionLost(self, reason):
        print "Lost Connection With Server!"
        #self.factory.clients.remove(self)
        #self.transport.loseConnection()
        print 'connection aborted!'
        #reactor.callFromThread(reactor.stop)
        reactor.stop ()
        return

    def lineReceived(self, line):
        #print "received", repr(line)
        line = line.strip ()
        if line == "EOF":
            print "Test Completed"
        self.factory.getLastReceivedMsg (line)
        exeResult = self.runPythonCommands.runPythonCommand(line.strip())

        self.sendLine(exeResult)
        EchoClientFactory.lastReceivedMessage = ""
        EchoClientFactory.clientObject[0].receivedMessages = []
        return

    def message (self, line):
        self.sendLine(line)
        #print line
        return


class EchoClientFactory(ClientFactory):
    protocol = MyChat
    clientObject = []
    lastReceivedMessage = ''

    def buildClientObject (self, newClient):
        client = Client ()
        self.clientObject.append(client)
        self.clientObject[0].objectProtocolInstance = newClient

        return

    def getLastReceivedMsg (self, message):
        self.lastReceivedMessage = message
        self.clientObject [0].lastReceivedMsg = message
        self.clientObject[0].receivedMessages.append (message)
        return 
    def connectionLost (self):
        reactor.stop()
        return

    def clientConnectionFailed(self, connector, reason):
        print 'Connection failed. Reason:', reason
        connector.connect () 
        return

这是我为我写的client_plugin.py:

from zope.interface import implements
from twisted.python import usage
from twisted.plugin import IPlugin
from twisted.application.service import IServiceMaker
from twisted.application.internet import TCPServer
from twisted.spread import pb
from slave.client import EchoClientFactory,MyChat, Client, RunPythonCommands, MyError, line


class Options(usage.Options):
    optParameters = [["port", "p", 8789, "The port number to listen on."], ["host", "h", "192.168.47.187", "The host to connect to"]]

class MyServiceMaker(object):
    implements(IServiceMaker, IPlugin)
    tapname = "echoclient"
    description = "Echo Client"
    options = Options

    def makeService(self, options):
        clientfactory = pb.PBServerFactory(EchoClientFactory ())
        return TCPServer(options["host"],int(options["port"]), clientfactory)

serviceMaker = MyServiceMaker()

我使用了文档中提到的相同文件夹层次结构.由于我无法在网上找到足够的插件示例,我现在真的陷入了困境.我将不胜感激任何帮助.谁能告诉我如何更改代码？先感谢您.

您是否应该使用这些tac文件从命令行运行它？

然后MyChat在另一个程序中使用你的类应该更容易......
