判断用户是否已经登录跳转到不同页面或者执行不同动作

1.

2.

<fig.VIP_URL}/Member/user_pwd/"找回登录密码 <找回登录密码

3.后台设置全局变量并查询用户信息

'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"),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'])){
        //<a href="https://www.jb51.cc/tag/yonghu/" target="_blank" class="keywords">用户</a>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);
            header('Location:/Login/Login');
            return false;
        }
        //超时的不能<a href="https://www.jb51.cc/tag/zaizhe/" target="_blank" class="keywords">在这</a>做，原因是存入session的值不变，如果<a href="https://www.jb51.cc/tag/yonghu/" target="_blank" class="keywords">用户</a>一直操作的话，而且只登陆一次，那么就会出现问题
    }
    return true;
}</span></pre>
