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
