Define permissions
首先，你需要明确系统中的角色和权限。将权限划分为不同的角色，例如管理员、普通用户、编辑者等。每个角色可以拥有不同的权限，例如访问某个页面、进行某个操作等。定义权限的粒度取决于你的系统需求。
提示：以下是本篇文章正文内容，下面案例可供参考
1. User login and authentication
Implement the user login function and obtain the user's role information and permissions after the user successfully logs in. A back-end API is usually used for user authentication and obtaining the user's role and permission information.
2. Front-end routing control
Use front-end routing to control page access. You can identify the permissions required by the page by adding meta information in the routing configuration, and then judge whether to allow access to the page based on the user's role and permission information in the navigation guard.
3. Menu permissions
The menu permission here refers to the token that will be returned by the backend after entering the user name and password when logging in, and then holding this token is to access the menu. Some users only have the viewing function but not editing, and some can view and edit.
4. Data level permission control
In some cases, permission control of data may be required. For example, a user can only view and edit data created by himself. At this time, you need to implement data permission filtering in the backend API to ensure that users can only access data for which they have permission.
5. Feedback on the front-end interface
When a user does not have permission to access a certain page or operation, a friendly prompt needs to be given to the user to tell him that he does not have permission to perform the operation. You can display an error message or jump to a specific unauthorized page.
6. Button permissions
The button permission means that after the user logs in to the page, he can perform specified processing on the page data. For example, on some pages, he can only add functions but not delete them. This kind of button permission belongs to the button permission.
Implementation ideas
RBAC implementation idea: users can add new user information and configure corresponding page permissions under the administrator account, and click the login button when the user logs in to jump to the specified menu and page.
ABAC implementation idea: define access policy rules according to business needs. A policy rule is a set of rules that determine whether a user has permission to access an object or perform an action. For example, you can define a policy rule so that only those with a specific role and the data owner is the current user can access the data.
Summarize
Permission management of the backend management system is a key component to ensure system security, compliance and user experience. Proper permission controls prevent unauthorized access, protect sensitive data, and ensure proper system operation
