如何在 twisted.web 中存储连接实例？我见过 request.getSession() 但我搜索过，关于它如何存储和稍后检索的例子很少。

谢谢。

更新： 我想将 ldap 连接存储在会话中以便稍后检索

  def render_POST(self, request):

    command = request.path[1:]
    session = request.getSession()

    if command == "authentication":
      Connect = LdapConnection(request.args['host'][0],request.args['user'][0],request.args['password'][0])
      session.addComponent(LdapConnection, Connect)                  

    if command == "users":
      Connect = session.getComponent(LdapConnection)                     
      u = Users(Connect, request.args['name'][0],request.args['employeeNumber'])

    return

twisted的文档中有很多示例。如果您喜欢快速总结如何使用会话。

from twisted.web.resource import Resource

class ShowSession(Resource):
    def render_GET(self, request):
        return 'Your session id is: ' + request.getSession().uid

class ExpireSession(Resource):
    def render_GET(self, request):
        request.getSession().expire()
        return 'Your session has been expired.'

resource = ShowSession()
resource.putChild("expire", ExpireSession())

不要忘记 request.getsession() 将创建会话，如果它不存在的话。本教程解释了如何在 session 中存储对象。

cache()

from zope.interface import Interface, Attribute, implements
from twisted.python.components import registerAdapter
from twisted.web.server import Session
from twisted.web.resource import Resource

class ICounter(Interface):
    value = Attribute("An int value which counts up once per page view.")

class Counter(object):
    implements(ICounter)
    def __init__(self, session):
        self.value = 0

registerAdapter(Counter, Session, ICounter)

class CounterResource(Resource):
    def render_GET(self, request):
        session = request.getSession()
        counter = ICounter(session)   
        counter.value += 1
        return "Visit #%d for you!" % (counter.value,)

resource = CounterResource()
