$session = $this->cache->memcached->save($data['session3rd'], $data['openId'] . $data['sessionKey']);
//检查user表是否存在改用户，如果存在，则则返回session，如果不存在，写入表再发回session
$find = $this->General->query('user',array('openid'=>$data['openId']));
$find = $find ==null ? 0:$find;
if($find == 0)

}
if(isset($find['avatarUrl'] && $find['avatarUrl'] !== $data['avatarUrl'])

}
echo json_encode(array('status'=>0,'session3rd'=>$data['session3rd'],'user_id'=>$user_id));
}
function checkLogin()
{ //如果客户端存在 session3rd，则post 到此接口，获取对应数据
$session3rd = $this->input->post('session3rd');
