龙卷风请求处理程序

Question

出于某种原因,我无法在MainHandler之外实例化set_cookie ..这是一个小代码来显示我想要做什么..任何人都可以帮忙吗？

import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web
from tornado.options import define, options
from GenCookie import * 

class MainHandler(tornado.web.RequestHandler):
     def get(self):
       g=GenCookie()
       response = g.genCookie()

class GenCookie:
 def genCookie(self):
    print self.request.remote_ip
    print self.cookies
    print self.request.headers
    expires = datetime.datetime.utcnow() + datetime.timedelta(days=365)
    if ("uid" in cookies):
       self.set_cookie("uid", value=cookies["uid"],expires=expires)
    else:
       self.set_cookie("uid", value='dfc278623ab44df2bd501e106e81d146',expires=expires)
    return

有任何想法吗？

我认为这解释了自己.

set_cookie是tornado.web.RequestHandler的一种方法

而在你的代码"self.set_cookie"中,self指的是GenCookie类的对象.

您的代码可以修改以传递必要的参考

class MainHandler(tornado.web.RequestHandler):
     def get(self):
       g=GenCookie(self)
       response = g.genCookie()

class GenCookie:
 def __init__(self, reqHandler):
    self.reqHandler = reqHandler

 def genCookie(self):
    print self.request.remote_ip
    print self.cookies
    print self.request.headers
    expires = datetime.datetime.utcnow() + datetime.timedelta(days=365)
    if ("uid" in self.cookies):
       self.reqHandler.set_cookie("uid", value=self.cookies["uid"],expires=expires)
    else:
       self.reqHandler.set_cookie("uid", value='dfc278623ab44df2bd501e106e81d146',expires=expires)
    return
