Python 使用简单的Twisted聊天服务器时遇到问题
当我尝试运行这个程序时(请参阅下面的代码),我从服务器和命令提示符获得“connectionmake”响应,以编写输入。但是,当我尝试输入时,它只是挂起,服务器似乎没有收到消息。有人知道这是为什么吗 谢谢,如果这不够清楚,请说 这是我的聊天服务器:Python 使用简单的Twisted聊天服务器时遇到问题,python,client,chat,twisted,server,Python,Client,Chat,Twisted,Server,当我尝试运行这个程序时(请参阅下面的代码),我从服务器和命令提示符获得“connectionmake”响应,以编写输入。但是,当我尝试输入时,它只是挂起,服务器似乎没有收到消息。有人知道这是为什么吗 谢谢,如果这不够清楚,请说 这是我的聊天服务器: from twisted.protocols import basic class MyChat(basic.LineReceiver): def connectionMade(self): print "Got new
from twisted.protocols import basic
class MyChat(basic.LineReceiver):
def connectionMade(self):
print "Got new client!"
self.factory.clients.append(self)
def connectionLost(self, reason):
print "Lost a client!"
self.factory.clients.remove(self)

from twisted.internet import reactor, protocol
from twisted.application import service, internet
factory = protocol.ServerFactory()
factory.protocol = MyChat
factory.clients = []
reactor.listenTCP(8004, factory)
reactor.run()
这是我的客户:
from twisted.internet import reactor, protocol
# a client protocol
class EchoClient(protocol.Protocol):
def sendData(self):
data = raw_input("> ")
if data:
print "sending %s...." % data
self.transport.write(data)
else:
self.transport.loseConnection()
def connectionMade(self):
self.sendData()
def dataReceived(self, data):
print data
self.sendData()
def connectionLost(self, reason):
print "connection lost"
class EchoFactory(protocol.ClientFactory):
protocol = EchoClient
def clientConnectionFailed(self, connector, reason):
print "Connection failed - goodbye!"
reactor.stop()
def clientConnectionLost(self, connector, reason):
print "Connection lost - goodbye!"
reactor.stop()
# this connects the protocol to a server runing on port 8000
def main():
f = EchoFactory()
reactor.connectTCP("localhost", 8004, f)
reactor.run()
# this only runs if the module was *not* imported
if __name__ == '__main__':
main()
你在客户身上犯了一个错误。基本上,服务器希望接收行,这意味着数据被换行符终止。但是,客户端发送的数据末尾没有换行符 因此,要修复客户端,只需将
\r\n
添加到数据中:
self.transport.write(data + "\r\n")
以下是客户端协议:
class EchoClient(protocol.Protocol):
def sendData(self):
data = raw_input("> ")
if data:
print "sending %s...." % data
self.transport.write(data + "\r\n")
else:
self.transport.loseConnection()
def connectionMade(self):
self.sendData()
def dataReceived(self, data):
print data
self.sendData()
def connectionLost(self, reason):
print "connection lost"
谢谢你,真的很有帮助:-)
