PHP MVC中RBAC的最佳实现方案的比较

php rbac

个人认为的PHP MVC框架中实现RBAC的原理 顺序:

数据表

1

2

3

4

5

<code>1.tb_user(id,uname,roleid)

2.tb_role(roleid,rolename)

3.tb_module(moduleid,moudulename,mvc_url)

4.tb_access(accessid,roleid,mouduleid)

</code>

Copy after login
Copy after login

实现原理

3

4

5

6

<code>1. 根据$uid 得到 $roleid

2. 根据当前MVC参数 __CLASS__ __METHOD__ 拼接成路由网址 $mvc_url

3. 根据 $mvc_url 去表 tb_module中查询,得到 $moduleid

4. 根据 $roleid,$mouduleid 查询表 tb_access中是否有此条记录

5. 如果 有,可以访问;如果没有,禁止访问该动作 action 方法

</code>

Copy after login
Copy after login

缺点
假如有一个模块, class Article,方法function lists();。
如果当前用户只有查看权限却没有修改、添加、删除权限,那么lists页面中关于 添加 修改 删除 按钮如何判断?

<code>1.tb_user(userid,username,roleid)

2.tb_role(roleid,rolename)

3.tb_module(moduleid,moudulename,link,upid)

4.tb_permission(roleid,title,mouduleid,permission)

</code>

Copy after login
Copy after login

其中 permission 的值有这几种

1

2

<code>{1:查看,2:添加,4:修改,8:删除,16:...}

</code>

Copy after login
Copy after login

RBAC实现流程
1.通过用户的 $userid 得到 $roleid
2.通过用户当前的网址去查询tb_module表中对应的link,得到 $moduleid。如果该module有父模块。那么获得他的父模块。比如当前模块MVC网址是 article/add,那么他的真正moduleid是

<code>select moduleid from tb_module

where id=(

    select upid from tb_module where link='article/add'

)

</code>

Copy after login
Copy after login

3.通过 $roleid 和 $moduleid 去查询 tb_permission,得到记录总和

<code>select sum(permission) as permission from tb_permission

where roleid=$roleid and moduleid=$moduleid

</code>

    case 4://访问、添加、修改权限

        break;

 

    case 8://访问、添加、修改、删除权限

        break;

 

    case 16:

        break;

}

</code>

对于第二种方法,说下看法,类似于电脑文件的 0777这种权限。
