2.

<if condition="$GLOBALS['userinfo']['user_id'] gt 0"><span class="help_wz"><a href="{$Think.config.VIP_URL}/Member/user_pwd/" style="color:#404958;">找回登录密码</a></span><else/><span class="help_wz"><a href="/Login/FindPwd" style="color:#404958;">找回登录密码</a></span></if>

3.后台设置全局变量并查询用户信息

public function UserInfo($user_id){//查询系统信息$system=array('CmdId'=>'System','Token'=>'wap','PostDetails'=>json_encode(array()));//通过curl的post方式发送接口请求$curl=new CurlController();$strs=$curl->SendCurl($system);$GLOBALS['system']=$strs['AcctDetails'];if(empty($user_id)){return false;}setcookie("login_uid", $user_id, time() + 3600, "/", C('cookie_url'));setcookie("rdun", $this->authcode($user_id . "," . time(), "ENCODE"), time() + 3600,"/",C('cookie_url'));;$data=array('CmdId'=>'Individual','Token'=>session('token'),'PostDetails'=>json_encode(array('user_id'=>$user_id,)));//通过curl的post方式发送接口请求$curl=new CurlController();$str=$curl->SendCurl($data);$GLOBALS['userinfo']=$str['AcctDetails'];$newtoken=unserialize($str['AcctDetails']['token']);$oldtoken=unserialize(session('token'));if(!empty(session('token')) && !empty($str['AcctDetails']['token'])){//用户不对if($newtoken['user_id'] !== $newtoken['user_id']){session('token',null);session('user_id',null);header('Location:/Login/Login');return false;}//token不对if($newtoken['time'] !== $oldtoken['time']){session('token',null);session('user_id',null);header('Location:/Login/Login');return false;}//超时的不能在这做，原因是存入session的值不变，如果用户一直操作的话，而且只登陆一次，那么就会出现问题}return true;}
