PHP MVC中RBAC的最佳实现方案的比较
个人认为的PHP MVC框架中实现RBAC的原理 顺序:
数据表
<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>
实现原理
<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>
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?
另外一个方法
数据表
<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>
其中 permission 的值有这几种
<code>{1:查看,2:添加,4:修改,8:删除,16:...} </code>
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>
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=$moduleid </code>
4.如果当前访问 article/lst
<code>switch($permission){ case 1: //只有访问权限 break; case 2://访问、添加权限 break; 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。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
