How to use PHP and Vue to implement user rights management functions

In modern web applications, user rights management is a very important function. It can help us control user access rights to various resources in the system. This article will introduce how to use PHP and Vue framework to implement user rights management functions.

1. Create database tables

First, we need to create several tables in the database to store permission-related data. Suppose we have the following tables:

• users: stores information about all users
• roles: stores information about all roles
• permissions: stores information about all permissions
• role_user: Stores the association between users and roles
• permission_role: Stores the association between roles and permissions

2. Implements user login and Permission verification interface

On the PHP side, we can create a login interface to verify the user's identity and return user-related permission information. The following is a simple implementation example:

<?php
// login.php

// 接收前端传递过来的用户名和密码
$username = $_POST['username'];
$password = $_POST['password'];

// 根据用户名和密码查询用户信息
// 检查用户名和密码是否匹配

// 如果匹配成功，返回用户信息和权限信息
$response = [
  'success' => true,
  'user' => [
    'id' => $user_id,
    'username' => $username
  ],
  'permissions' => $permissions
];

echo json_encode($response);
?>

3. Get user permissions in Vue applications

In Vue applications, we can obtain user permissions by calling the login interface information. The following is a simple implementation example:

// 使用axios发送登录请求
axios.post('/api/login', {
  username: 'admin',
  password: 'password'
})
.then(response => {
  // 保存用户信息和权限信息到Vuex或LocalStorage
  store.commit('setUser', response.data.user);
  store.commit('setPermissions', response.data.permissions);
})
.catch(error => {
  console.error(error);
});

4. Use Vue's routing guard for permission verification

In a Vue application, we can use Vue's routing guard for permissions verify. The following is a simple implementation example:

// 在路由定义中使用路由守卫
const router = new VueRouter({
  routes: [
    {
      path: '/dashboard',
      component: Dashboard,
      meta: {
        requiresAuth: true,
        requiresPermission: 'dashboard:view'
      }
    },
    // ...
  ]
});

// 路由守卫函数
router.beforeEach((to, from, next) => {
  // 检查是否需要登录验证
  if (to.meta.requiresAuth && !store.getters.isAuthenticated) {
    next('/login');
  } else {
    // 检查是否需要权限验证
    if (to.meta.requiresPermission && !store.getters.hasPermission(to.meta.requiresPermission)) {
      next('/403');
    } else {
      next();
    }
  }
});

// 在Vue组件中使用路由守卫
export default {
  created() {
    // 在组件创建时检查是否有权限访问
    if (this.$route.meta.requiresPermission && !this.$store.getters.hasPermission(this.$route.meta.requiresPermission)) {
      this.$router.push('/403');
    }
  }
  // ...
};

The above is a simple example of using PHP and Vue to implement user rights management functions. Of course, in real projects, we still need to further improve the functions and handle various business scenarios. I hope this article can help you understand and implement user rights management functions.
