我如何給扭曲的服務器一個 IP 地址？

Question

我正在嘗試編寫一個簡單的客戶端/服務器（其中客戶端和服務器不是同一台機器）並且無法弄清楚如何提供扭曲的 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()

錯誤：

Traceback (most recent call last):
  File "sensors/twistedTest.003.py", line 20, in <module>
    fingerEndpoint = endpoints.serverFromString(reactor, ("192.168.1.7", "tcp:1079"))

    args, kw = _parse(description)

我如何給 Twisted/reactor 一個 IP 地址？

Answer 1

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

像這樣：

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

此外，地址“192.168.1.7”應該是服務器機器上某些網絡接口的地址。
