Django中使用session保持用户登陆连接的例子

if request.session.get('is_login',None):   return HttpResponseRedirect(reverse('index'))

request.session['is_login'] = Truerequest.session['user_id'] = db_user.idrequest.session['user_name'] = db_user.name

def logout(request):  if not request.session.get('is_login', None):    # 如果本来就未登录，也就没有登出一说    return redirect("/index/")  request.session.flush()  # 或者使用下面的方法  # del request.session['is_login']  # del request.session['user_id']  # del request.session['user_name']  return redirect("/index/")

{% if request.session.is_login %}   <li><a href="#" rel="external nofollow" >当前在线：{{ request.session.user_name }}</a></li>   <li><a href="/logout/" rel="external nofollow" >登出</a></li> {% else %}   <li><a href="/login/" rel="external nofollow" >登录</a></li>   <li><a href="/register/" rel="external nofollow" >注册</a></li>{% endif %}
