python - 如何给twisted服务器一个IP地址？

问题描述

我正在尝试编写一个简单的客户端/服务器（其中客户端和服务器不是同一台机器）并且无法弄清楚如何给扭曲的 IP 地址。

from twisted.internet import protocol, reactor, endpoints
from twisted.protocols import basic

class FingerProtocol(basic.LineReceiver):
    def lineReceived(self, user):
        self.transport.write(self.factory.getUser(user) + b"\r\n")
        self.transport.loseConnection()

class FingerFactory(protocol.ServerFactory):
    protocol = FingerProtocol

    def __init__(self, users):
        self.users = users

    def getUser(self, user):
        return self.users.get(user, b"No such user")

fingerEndpoint = endpoints.serverFromString(reactor, ("192.168.1.7", "tcp:1079"))
fingerEndpoint.listen((FingerFactory({ b'moshez' : b'Happy and well'})))
reactor.run()

错误：

Traceback (most recent call last):
  File "sensors/twistedTest.003.py", line 20, in <module>
    fingerEndpoint = endpoints.serverFromString(reactor, ("192.168.1.7", "tcp:1079"))
  File "/usr/local/lib/python3.5/dist-packages/twisted/internet/endpoints.py", line 1724, in serverFromString
    nameOrPlugin, args, kw = _parseServer(description, None)
  File "/usr/local/lib/python3.5/dist-packages/twisted/internet/endpoints.py", line 1635, in _parseServer
    args, kw = _parse(description)
  File "/usr/local/lib/python3.5/dist-packages/twisted/internet/endpoints.py", line 1596, in _parse
    for (type, value) in _tokenize(description):

如何给twisted/reactor 一个IP 地址？

标签： pythonpython-3.xtwistedreactor

解决方案

而不是使用 ("192.168.1.7", "tcp:1079") 尝试 b"tcp:1079:interface=192.168.1.7"。

像这样：

fingerEndpoint = endpoints.serverFromString(reactor, b"tcp:1079:interface=192.168.1.7")

此外，地址“192.168.1.7”应该是服务器机器上某些网络接口的地址。
