如何使用PHP和Vue開發倉庫管理的倉庫安全管理功能

CREATE TABLE `warehouses` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `location` varchar(255) NOT NULL,
  `security_level` int(11) NOT NULL,
  PRIMARY KEY (`id`)
);

<?php
  $db_host = "localhost";  // 数据库主机名
  $db_user = "root";       // 数据库用户名
  $db_password = "";       // 数据库密码
  $db_name = "your_database_name";  // 数据库名称

  // 连接数据库
  $conn = new mysqli($db_host, $db_user, $db_password, $db_name);

  // 检查连接是否成功
  if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
  }

  // 处理GET请求，获取仓库列表
  if ($_SERVER["REQUEST_METHOD"] === "GET") {
    $result = $conn->query("SELECT * FROM warehouses");
    $warehouses = [];
    while ($row = $result->fetch_assoc()) {
      $warehouses[] = $row;
    }
    echo json_encode($warehouses);
  }

  // 处理POST请求，添加新的仓库
  if ($_SERVER["REQUEST_METHOD"] === "POST") {
    $name = $_POST["name"];
    $location = $_POST["location"];
    $security_level = $_POST["security_level"];
    $sql = "INSERT INTO warehouses (name, location, security_level) VALUES ('$name', '$location', '$security_level')";
    if ($conn->query($sql) === TRUE) {
      echo "New warehouse added successfully";
    } else {
      echo "Error: " . $sql . "<br>" . $conn->error;
    }
  }

  // 处理DELETE请求，删除仓库
  if ($_SERVER["REQUEST_METHOD"] === "DELETE") {
    $id = $_GET["id"];
    $sql = "DELETE FROM warehouses WHERE id=$id";
    if ($conn->query($sql) === TRUE) {
      echo "Warehouse deleted successfully";
    } else {
      echo "Error: " . $sql . "<br>" . $conn->error;
    }
  }

  // 关闭数据库连接
  $conn->close();
