我在python中有一个非常基本的扭曲服务器/客户端设置。
server.py：
from twisted.internet.protocol import Protocol
from twisted.internet.protocol import Factory
from twisted.internet.endpoints import TCP4ServerEndpoint
from twisted.internet import reactor
class Echo(Protocol):
def __init__(self, factory):
self.factory = factory
def connectionMade(self):
print("Connection made")
def connectionLost(self):
print("Connection lost")
def dataReceived(self, data):
print("Received data")
print(data)
self.transport.write(data)
class EchoFactory(Factory):
def buildProtocol(self, addr):
return Echo(self)
def main():
PORT = 9009 #the port you want to run under. Choose something >1024
endpoint = TCP4ServerEndpoint(reactor, PORT)
endpoint.listen(EchoFactory())
reactor.run()
if __name__ == "__main__":
main()
client.py：
from twisted.internet import reactor
from twisted.internet.protocol import Protocol
from twisted.internet.endpoints import TCP4ClientEndpoint, connectProtocol
class Greeter(Protocol):
def sendMessage(self, msg):
print('sending message')
self.transport.write("MESSAGE %s\n" % msg)
print('message sent')
def gotProtocol(p):
p.sendMessage("Hello")
reactor.callLater(1, p.sendMessage, "This is sent in a second")
reactor.callLater(2, p.transport.loseConnection)
PORT = 9009
point = TCP4ClientEndpoint(reactor, "localhost", PORT)
d = connectProtocol(point, Greeter())
d.addCallback(gotProtocol)
print('running reactor')
reactor.run()
当我使用Telnet客户端ping服务器并收到预期的响应时，服务器工作正常。但是，当我尝试运行client.py时，它卡在了“ self.transport.write（” MESSAGE％s \ n“％msg）”处。或者至少我认为是这样做的，因为打印到控制台的最后一件事是“发送消息”。
我已经搜索了几天，但似乎无法弄清楚出了什么问题（我是网络新手）。我在这里做错了什么？我正在使用Python 3并正在运行Windows 8.1。
