我正在使用Twisted web“HTTPClient”协议与http服务器对话(使用扭曲的应用程序作为客户端),问题是我的大多数请求都不接受我的标题。是否有某种方式(可能使用某些库)生成标题? 我会发布一些代码,以便你看看
class Local(HTTPClient):
def generateHeaders(self, type=None):
self.sendHeader('User-Agent', 'Twisted Web Client')
if type:
self.sendHeader('Content-Type', 'x-www-form-urlencoded')
self.sendHeader('Accept', '*/*')
self.sendHeader('Host', 'localhost')
self.endHeaders()
def connectionMade(self):
## GENERATE ID
self.userid= self.generateID()
self.sendCommand('POST', '/chat/action=join&user=pirosb3')
self.generateHeaders(type=True)
def dataReceived(self, data):
print data
正如你所看到的,我创建了一个为我生成标题的方法,但是我必须说,我总是得到错误响应。
任何人都知道解决方案吗?

我肯定会建议您使用Twisted的Agent
课程以及Header
模块中的twisted.web.http_headers
课程。
有一本很好的指南here。
如果您需要Twisted HTTP客户端的实际示例,该客户端会向请求添加一些标头并且可以读取答案,这里是:
from pprint import pformat
from twisted.internet import reactor
from twisted.internet.defer import Deferred
from twisted.internet.protocol import Protocol
from twisted.web.client import Agent
from twisted.web.http_headers import Headers
class BeginningPrinter(Protocol):
def __init__(self, finished):
self.finished = finished
self.remaining = 1024 * 10
def dataReceived(self, bytes):
if self.remaining:
display = bytes[:self.remaining]
print 'Some data received:'
print display
self.remaining -= len(display)
def connectionLost(self, reason):
print 'Finished receiving body:', reason.getErrorMessage()
self.finished.callback(None)
agent = Agent(reactor)
d = agent.request(
'GET',
'http://example.com/',
Headers({'User-Agent': ['Twisted Web Client Example']}),
None)
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()))
finished = Deferred()
response.deliverBody(BeginningPrinter(finished))
return finished
d.addCallback(cbRequest)
def cbShutdown(ignored):
reactor.stop()
d.addBoth(cbShutdown)
reactor.run()
