User rights management and authorization verification for PHP and mini programs

User rights management and authorization verification of PHP and mini programs

With the rapid development of the mobile Internet, mini programs have become the development platform chosen by more and more enterprises and individuals. User rights management and authorization verification of mini programs is a very important issue and is crucial to protecting user information and data security. This article will introduce the implementation method of user rights management and authorization verification in PHP backend and mini program frontend, and attach corresponding code examples.

1. User rights management

User rights management is a method of maintaining the security and integrity of the system by controlling user access rights to system resources. In the mini program, user rights management can be achieved through the following steps:

1.1 Define user roles and permissions

First, we need to define different user roles and corresponding permissions. For example, for an e-commerce mini program, we may define the following roles and permissions:

• Ordinary users: can browse products and place orders to purchase products
• Merchant: can publish products, Manage orders
• Administrator: can manage user permissions and review merchant products

1.2 Create a database table and store user role and permission information

Created in MySQL database A table that stores a user's role and permission information. The structure of the table can be as follows:

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(255) NOT NULL,
  `password` varchar(255) NOT NULL,
  `role` int(11) NOT NULL,
  PRIMARY KEY (`id`)
);

In this table, we need to add a role field to represent the user's role. You can use numbers to represent different roles, such as 1 for ordinary users, 2 for merchants, and 3 for administrators.

1.3 Verify user permissions

After receiving the user's request, we can verify the user's permissions by obtaining the user's role information and comparing the permissions with the requested resources. The following is a sample code for PHP backend to verify user permissions:

<?php
// 获取请求的资源
$resource = $_GET['resource'];

// 获取用户角色信息
$userRole = getUserRole();

// 检查用户权限
if (checkPermission($userRole, $resource)) {
  // 用户有权限访问该资源
  // 处理请求...
} else {
  // 用户没有权限访问该资源
  // 返回错误信息...
}

// 获取用户角色信息
function getUserRole() {
  // 根据用户的身份信息，在数据库中查询对应的角色信息
  // 返回用户的角色
}

// 检查用户权限
function checkPermission($userRole, $resource) {
  // 根据用户的角色和资源信息，判断用户是否有权限访问该资源
  // 返回布尔值
}
?>

2. Authorization verification

Authorization verification refers to authorizing the request when the mini program front-end sends a request Verify to ensure the legality and validity of the request. The following is a sample code for a small program front-end to send an authorization verification request:

// 小程序前端代码
const API_BASE_URL = 'https://api.example.com';

// 发送请求前进行授权验证
function request(url, method, data) {
  // 获取用户的授权信息
  const token = getUserToken();

  // 发送请求
  return new Promise((resolve, reject) => {
    wx.request({
      url: API_BASE_URL + url,
      method: method,
      data: data,
      header: {
        'Authorization': 'Bearer ' + token
      },
      success: resolve,
      fail: reject
    });
  });
}

// 获取用户的授权信息
function getUserToken() {
  // 从小程序的缓存中获取用户的授权信息
  // 返回用户的授权信息
}

// 调用示例
request('/user/info', 'GET')
  .then(res => {
    // 处理响应结果
  })
  .catch(err => {
    // 处理错误信息
  });

In the sample code for authorization verification, we obtain the user's authorization information and add the authorization information to the header of the request to complete Authorization verification. In the PHP backend, the request needs to be parsed and the validity of the authorization information verified.

To sum up, user rights management and authorization verification of PHP and mini programs are an important part of protecting data security and user privacy. By properly defining user roles and permissions and implementing corresponding authorization verification, you can ensure that users can only access resources for which they have permission, thereby improving the security and user experience of mini programs.

Note: The above code examples are for reference only, and the specific implementation needs to be adjusted and expanded according to the specific business and technical framework.
