如何使用PHP和Vue開發支付後會員積分的積分凍結功能

<?php
  $host = 'localhost'; //数据库地址
  $dbname = 'your_db_name'; //数据库名
  $username = 'your_username'; //数据库用户名
  $password = 'your_password'; //数据库密码
  
  try {
    $db = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
  } catch (PDOException $e) {
    die('数据库连接失败：' . $e->getMessage());
  }
?>

<?php
  require_once 'api.php'; //引入数据库连接

  //验证用户身份
  function validateUser($token) {
    //使用JWT验证用户身份，具体代码请参考JWT的相关文档
  }

  //更新会员积分和冻结状态
  function updatePoints($token, $username, $points, $isFrozen) {
    validateUser($token);

    try {
      $stmt = $db->prepare("UPDATE members SET points = :points, frozen = :frozen WHERE username = :username");
      $stmt->bindParam(':points', $points);
      $stmt->bindParam(':frozen', $isFrozen);
      $stmt->bindParam(':username', $username);
      $stmt->execute();

      echo json_encode(array('message' => '会员积分更新成功'));
    } catch (PDOException $e) {
      echo json_encode(array('message' => '会员积分更新失败：' . $e->getMessage()));
    }
  }

  //调用updatePoints函数
  $data = json_decode(file_get_contents('php://input'), true);

  $token = $data['token'];
  $username = $data['username'];
  $points = $data['points'];
  $isFrozen = $data['isFrozen'];

  updatePoints($token, $username, $points, $isFrozen);
?>

vue create member-points

import Axios from 'axios';

export default {
  data() {
    return {
      token: '',
      username: '',
      points: 0,
      isFrozen: false
    }
  },
  methods: {
    updatePoints() {
      const data = {
        token: this.token,
        username: this.username,
        points: this.points,
        isFrozen: this.isFrozen
      };

      Axios.post('http://localhost/api/updatePoints.php', data)
        .then(response => {
          console.log(response.data);
        })
        .catch(error => {
          console.log(error);
        });
    }
  }
}
