Django利用cookie保存用户登录信息的简单实现方法

response对象.set_cookie('key','value',多少秒后过期)

request对象.COOKIES.get('key')

def hi(request):
  msg = {'result':''}
  loginSuccess = False # 是否登录成功标识
  if user.userLogin(request.POST.get('username'),request.POST.get('pwd')):
    loginSuccess = True
    msg['result'] = '登录成功'
  elif request.COOKIES.get('userlogin_username') != None :
    msg['result'] = '已经登录,当前用户是:' + request.COOKIES.get('userlogin_username')
  else:
    msg['result'] = '登录失败'
  myReponse = render_to_response("index.html",msg)
  # 如果登录成功,则设置cookies
  if loginSuccess:
    myReponse.set_cookie('userlogin_username',request.POST.get('username'),3600)
  return myReponse
