RBAC 基于角色的权限管理的简略实现
RBAC 基于角色的权限管理的简单实现
1、什么是权限管理,权限管理就是对后台功能的细分,和对不同工作人员划分不同的工作的管理
RBAC是如何实现的,通过对不同控制器和控制器不同方法的限制,实现的管理。
要实现RBAC需要三张表,一张用户表,一张角色表 ,一张权限表
用户表:
id ****** role_id
角色表
role_id ****** access_ids(记录所有可以访问的权限id)
权限表
access_id
记录所有控制器 或者控制器下的 action
2、如何控制,在控制器的父类 或者控制器的初始化的方法里面做判断即可
$role_id = $_SESSION[‘role_id’];
$role = $db->role->findByPk($role_id);
$access = $db->access->findAllByPk($role[‘access_id’]);
根据路由器类获取要执行的控制器或者控制器方法
$m = current_method();//获取当前要访问的方法
if(!in_array($m, $access)){
redirect(‘/index’);
}

DAO (Data Access Object) in Java is used to separate application code and persistence layer, its advantages include: Separation: Independent from application logic, making it easier to modify it. Encapsulation: Hide database access details and simplify interaction with the database. Scalability: Easily expandable to support new databases or persistence technologies. With DAOs, applications can call methods to perform database operations such as create, read, update, and delete entities without directly dealing with database details.

In Java, a "field" is a data member in a class or interface that is used to store data or state. The properties of field include: type (can be any Java data type), access rights, static (belongs to a class rather than an instance), final (immutable) and transient (not serialized). Field is used to store state information of a class or interface, such as storing object data and maintaining object state.

The Java reflection mechanism allows programs to dynamically modify the behavior of classes without modifying the source code. By operating the Class object, you can create instances through newInstance(), modify private field values, call private methods, etc. Reflection should be used with caution, however, as it can cause unexpected behavior and security issues, and has a performance overhead.

What does a computer memory module look like? This is an overview of the graphics card and memory module in the computer. The computer's independent graphics card is inserted into the graphics card slot, with a fan, and the memory module is inside the memory module slot on the computer's motherboard, shaped like a green rectangle. Laptop memory modules are different from desktop memory modules, and they cannot be used interchangeably. Appearance difference 1: Desktop memory, slender, 13-14 cm in length. 2: Notebook memory is shorter, about five centimeters. Memory is the bridge in the computer, responsible for data exchange between the processor and hardware such as hard disk, motherboard, and graphics card. The red circle on the way is the memory stick, next to the CPU fan and plugged into the memory stick. Look, a computer memory stick looks like this. Use a screwdriver to open the cover of the desktop computer. The red circle in the middle is the memory module. What is a memory stick?
