如何使用token实现权限

前端代码参考

<p style="color: #5a6268;font-size: 30px;font-weight: bold;text-align: center;">登录页面</p>
<form style="width: 30%;margin: 0 auto">
    <label>用户名</label>
    <input type="text" id="t_name" class="form-control" >
    <br>
    <label >密码</label>
    <input type="password" id="t_pwd" class="form-control">
    <br>
    <button type="button" class="btn btn-primary">确认登录</button>
</form>
</body>
</html>

<script>
    $('.btn').click(function () {
        var t_name=$(this).siblings('#t_name').val();
        var t_pwd=$(this).siblings('#t_pwd').val();


        $.ajax({
            "url":'/admin/add/login',
            "type":"POST",
            "data":{
                't_name':t_name,
                't_pwd':t_pwd,
                '__token__':"{$Request.token}",
            },
            "dataType":"json",
            "success":function (res) {
                console.log(res.data);
                if(res.code==200){
                    alert('登录成功');
                    localStorage.setItem('token',res.data.token);//将token上传到游览器本地化
                    window.location.href="{:url('admin/add/index')}";
                }
            },
            "error":function (error) {
                console.log(error);
            }
        })
    })
</script>

控制器代码参考：
public function login(){
        $param=request()->post();

        $data = [
            't_name' =>$param['t_name'],
            't_pwd' =>$param['t_pwd'],
        ];
        $res=stus::loginDo($data);

        if(empty($res)){
            return json(['code'=>0,'data'=>'','msg'=>'登录失败']);
        }else{

            $token = Token::createToken($res['t_id']);
            $res['token']=$token;
           session('token',$token);
            $admin=stus::getUserNodeAll($res['t_id']);
//            return json($admin);
           session('admin',$admin);
            return json(['code'=>200,'data'=>$res,'msg'=>'登录成功']);
        }
    }
    public function login(){
        $param=request()->post();

        $data = [
            't_name' =>$param['t_name'],
            't_pwd' =>$param['t_pwd'],
        ];
        $res=stus::loginDo($data);

        if(empty($res)){
            return json(['code'=>0,'data'=>'','msg'=>'登录失败']);
        }else{

            $token = Token::createToken($res['t_id']);
            $res['token']=$token;
           session('token',$token);
            $admin=stus::getUserNodeAll($res['t_id']);
//            return json($admin);
           session('admin',$admin);
            return json(['code'=>200,'data'=>$res,'msg'=>'登录成功']);
        }
    }

模型层代码参考：
   public static function loginDo($data){
        return self::where($data)->find();
    }
    public static function getUserNodeAll($id){
        $field='t_id,t_name,role,p_id,id';

        $userNode = self::alias('u')
            ->field($field)
            ->join('roles', 'a_id = t_id')
            ->where('t_id', $id)
            ->select();
//            return $userNode;
        return self::getTree($userNode,0);
    }
    public static function getTree($data,$p_id=0){
        $result=[];
        if(empty($data)){
            return $result;
        }
        foreach ($data as $key=>$item){
            if($item['p_id']==$p_id){
                $item['child']=self::getTree($data,$item['id']);
                $result[]=$item;
            }

        }
        return $result;die();
    }

layout代码参考：
<div class="sidebar-nav">

    {foreach $Think.session.admin as $vo}
    <a href="#{$vo.id}" class="nav-header collapsed" data-toggle="collapse"><i class="icon-exclamation-sign"></i>{$vo.role}</a>
    <ul id="{$vo.id}" class="nav nav-list collapse">
        {foreach $vo['child'] as $v}
        <li><a >{$v.role}</a></li>

        {/foreach}
    </ul>
    {/foreach}
</div>
