如何在此Twisted HTTP Client示例中访问远程对等IP? (来自Twisted Docs)
使用此示例:
from sys import argv
from pprint import pformat
from twisted.internet.task import react
from twisted.web.client import Agent, readBody
from twisted.web.http_headers import Headers
def cbRequest(response):
#print 'Response version:', response.version
#print 'Response code:', response.code
#print 'Response phrase:', response.phrase
#print 'Response headers:'
#print pformat(list(response.headers.getAllRawHeaders()))
poweredby = response.headers.getRawHeaders("X-Powered-By")
server = response.headers.getRawHeaders("Server")
print poweredby
print server
d = readBody(response)
d.addCallback(cbBody)
return d
def cbBody(body):
print 'Response body:'
#print body
def main(reactor, url=b"http://www.example.com/"):
agent = Agent(reactor)
d = agent.request(
'GET', url,
Headers({'User-Agent': ['Twisted Web Client Example']}),
None)
d.addCallback(cbRequest)
return d
react(main, argv[1:])
在互联网上搜索SO后,我发现可以从以下网址阅读:
self.xmlstream.transport.getHandle().getpeername()
或
self.transport.getPeer()
但是,我不知道哪个班级"自我"是指和将它放在示例代码中的哪个位置?
有任何帮助吗?提示?想法?
谢谢,

可以获取地址,但你必须破解一些抽象层并触摸私有属性:
from __future__ import print_function
from twisted.web.client import Agent
from twisted.internet.task import react
from twisted.internet.protocol import Protocol
from twisted.internet.defer import Deferred
class ReadAddress(Protocol):
def __init__(self):
self.result = Deferred()
def connectionMade(self):
self.result.callback(self.transport._producer.getPeer())
def readAddress(response):
p = ReadAddress()
response.deliverBody(p)
return p.result
@react
def main(reactor):
a = Agent(reactor)
d = a.request(b"GET", b"http://www.google.com/")
d.addCallback(readAddress)
d.addCallback(print)
return d
理想情况下,会有一个更简单的(公共!)接口来检索这样的信息。如果您可以在Twisted跟踪器中提交功能请求,那就太棒了。
