python扭曲簡單的服務器客戶端

Question

我正在嘗試構建一個簡單的“當天的報價”服務器和客戶端從扭曲的教程文檔中修改。 我希望從客戶那里打印出“當天的報價”以證明溝通。 但是，據我所知，客戶端沒有連接。 這是我的代碼。

服務器

from twisted.python import log
from twisted.internet.protocol import Protocol
from twisted.internet.protocol import Factory
from twisted.internet.endpoints import TCP4ServerEndpoint
from twisted.internet import reactor

class QOTD(Protocol):
    def connectionMade(self):
        self.transport.write("An apple a day keeps the doctor away\r\n") 
        self.transport.loseConnection()

class QOTDFactory(Factory):
    def buildProtocol(self, addr):
        return QOTD()

# 8007 is the port you want to run under. Choose something >1024
endpoint = TCP4ServerEndpoint(reactor, 8007)
endpoint.listen(QOTDFactory())
reactor.run()

客戶

import sys
from twisted.python import log
from twisted.internet import reactor
from twisted.internet.protocol import Factory, Protocol
from twisted.internet.endpoints import TCP4ClientEndpoint

class SimpleClient(Protocol):
    def connectionMade(self):
        log.msg("connection made")
        #self.transport.loseConnection()

    def lineReceived(self, line):
        print "receive:", line

class SimpleClientFactory(Factory):
    def buildProtocol(self, addr):
        return SimpleClient()

def startlog():
    log.startLogging(sys.stdout)

point =  TCP4ClientEndpoint(reactor, "localhost", 8007)
d = point.connect(SimpleClientFactory)
reactor.callLater(0.1, startlog)
reactor.run()

Answer 1

• 傳遞SimpleClientFactory的實例，而不是將類本身傳遞給point.connect()
• 如果使用lineReceived則從twisted.protocol.basic.LineReceiver而不是Protocol中lineReceived
• 調用addErrback上的結果endpoint.listen和point.connect處理錯誤
