PHP和Vue：如何實現會員積分的回饋或返點方式

CREATE TABLE members (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(255) NOT NULL,
  email VARCHAR(255) NOT NULL,
  balance INT NOT NULL DEFAULT 0
);

CREATE TABLE points (
  id INT AUTO_INCREMENT PRIMARY KEY,
  member_id INT NOT NULL,
  amount INT NOT NULL,
  type ENUM('bonus', 'refund', 'redeem') NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

<?php

class MemberController {
  // 获取会员列表
  public function getMembers() {
    // 在这里查询数据库获取会员列表，并返回给前端
  }
  
  // 添加会员
  public function addMember($data) {
    // 在这里将会员信息插入数据库
  }
  
  // 增加积分
  public function addPoints($data) {
    // 在这里将积分记录插入数据库，并更新会员的积分余额
  }
  
  // 减少积分
  public function deductPoints($data) {
    // 在这里将积分记录插入数据库，并更新会员的积分余额
  }
}
