核心类实现

}
控制器实现
1 商品控制器
<?php
// app/Controllers/ProductController.php
require_once __DIR__ . '/../Models/Product.php';
class ProductController {
private $productModel;
public function __construct() {
$this->productModel = new Product();

$keyword = isset($_GET['keyword']) ? trim($_GET['keyword']) : '';
$data = $this->productModel->getAllProducts($page, 12, $categoryId, $keyword);
// 返回JSON数据
header('Content-Type: application/json');

}
public function detail($id) {

if (!$product) {
http_response_code(404);
echo json_encode(['error' => '商品不存在']);
return;
}
// 获取相关商品
$relatedProducts = $this->productModel->getRelatedProducts(
$product['category_id'],
$product['id']
);
echo json_encode([
'product' => $product,
'related_products' => $relatedProducts
]);
}
}
2 购物车控制器
<?php
// app/Controllers/CartController.php
require_once __DIR__ . '/../Services/CartService.php';
require_once __DIR__ . '/../Middleware/AuthMiddleware.php';
class CartController {
private $cartService;
public function __construct() {

$productId = $_POST['product_id'];
$quantity = isset($_POST['quantity']) ? (int)$_POST['quantity'] : 1;
if (!$productId || $quantity < 1) {

return;
}
$result = $this->cartService->addToCart($userId, $productId, $quantity);
echo json_encode($result);
}
public function view() {
AuthMiddleware::checkAuth();
$userId = $_SESSION['user_id'];
$data = $this->cartService->getCartItems($userId);
header('Content-Type: application/json');
echo json_encode($data);
}
public function update() {
AuthMiddleware::checkAuth();
$userId = $_SESSION['user_id'];
$productId = $_POST['product_id'];
$quantity = (int)$_POST['quantity'];

}
public function remove() {
AuthMiddleware::checkAuth();
$userId = $_SESSION['user_id'];
$productId = $_POST['product_id'];
$result = $this->cartService->removeFromCart($userId, $productId);
echo json_encode(['success' => $result]);
}
}
3 订单控制器
<?php
// app/Controllers/OrderController.php
require_once __DIR__ . '/../Services/OrderService.php';
require_once __DIR__ . '/../Middleware/AuthMiddleware.php';
class OrderController {
private $orderService;
public function __construct() {
$this->orderService = new OrderService();
}
public function create() {
AuthMiddleware::checkAuth();
$userId = $_SESSION['user_id'];
$shippingAddress = $_POST['shipping_address'];
$paymentMethod = $_POST['payment_method'];
if (empty($shippingAddress)) {
echo json_encode(['success' => false, 'message' => '请填写收货地址']);
return;
}
$result = $this->orderService->createOrder(
$userId,
$shippingAddress,

);
echo json_encode($result);
}
public function list() {
AuthMiddleware::checkAuth();
$userId = $_SESSION['user_id'];
$status = isset($_GET['status']) ? (int)$_GET['status'] : null;
$orders = $this->orderService->getUserOrders($userId, $status);
header('Content-Type: application/json');
echo json_encode($orders);
}
public function detail($orderId) {
AuthMiddleware::checkAuth();
$userId = $_SESSION['user_id'];
$order = $this->orderService->getOrderById($orderId, $userId);
if (!$order) {
http_response_code(404);
echo json_encode(['error' => '订单不存在']);
return;
}
header('Content-Type: application/json');
echo json_encode($order);
}
}
路由配置
<?php
// routes/web.php
$route = $_GET['route'] ?? 'home';
// 简单的路由分发
switch ($route) {
// 用户相关
case 'register':
$controller = new AuthController();
$controller->register();
break;
case 'login':
$controller = new AuthController();
$controller->login();
break;
case 'logout':
$controller = new AuthController();
$controller->logout();
break;
// 商品相关
case 'products':
$controller = new ProductController();
$controller->list();
break;
case 'product':
$id = $_GET['id'] ?? 0;
$controller = new ProductController();
$controller->detail($id);
break;
// 购物车相关
case 'cart':
$controller = new CartController();
$controller->view();
break;
case 'cart_add':
$controller = new CartController();
$controller->add();
break;
case 'cart_update':
$controller = new CartController();
$controller->update();
break;
case 'cart_remove':
$controller = new CartController();
$controller->remove();
break;
// 订单相关
case 'order_create':
$controller = new OrderController();
$controller->create();
break;
case 'orders':
$controller = new OrderController();
$controller->list();
break;
case 'order_detail':
$id = $_GET['id'] ?? 0;
$controller = new OrderController();
$controller->detail($id);
break;
default:
echo json_encode(['message' => 'Welcome to E-commerce API']);
}
中间件
<?php
// app/Middleware/AuthMiddleware.php
class AuthMiddleware {
public static function checkAuth() {
session_start();
if (!isset($_SESSION['user_id'])) {
http_response_code(401);
echo json_encode(['error' => '未登录']);
exit;
}
}
}
性能优化建议
<?php
// app/Services/CacheService.php
class CacheService {
private $cacheDir;
public function __construct($cacheDir = __DIR__ . '/../../cache/') {
$this->cacheDir = $cacheDir;
if (!is_dir($cacheDir)) {
mkdir($cacheDir, 0777, true);
}
}
public function get($key) {
$file = $this->cacheDir . md5($key) . '.cache';
if (file_exists($file)) {
$data = unserialize(file_get_contents($file));
if ($data['expire'] > time()) {
return $data['value'];
}
unlink($file);
}
return null;
}
public function set($key, $value, $expire = 300) {
$file = $this->cacheDir . md5($key) . '.cache';
$data = [
'expire' => time() + $expire,
'value' => $value
];
file_put_contents($file, serialize($data));
}
}
安全措施
<?php
// app/Services/SecurityService.php
class SecurityService {
public static function sanitizeInput($data) {
if (is_array($data)) {
return array_map([self::class, 'sanitizeInput'], $data);
}
return htmlspecialchars(strip_tags(trim($data)));
}
public static function generateCsrfToken() {
if (empty($_SESSION['csrf_token'])) {
$_SESSION['csrf_token'] = bin2hex(random_bytes(32));
}
return $_SESSION['csrf_token'];
}
public static function validateCsrfToken($token) {
return isset($_SESSION['csrf_token']) && hash_equals($_SESSION['csrf_token'], $token);
}
public static function rateLimit($key, $maxAttempts = 5, $timeWindow = 300) {
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$count = $redis->incr($key);
if ($count === 1) {
$redis->expire($key, $timeWindow);
}
if ($count > $maxAttempts) {
return false;
}
return true;
}
}

这个电商系统核心模块包含了完整的用户认证、商品管理、购物车、订单处理和支付流程，你可以根据实际需求添加更多功能，如优惠券系统、评价系统、推荐算法等，记住在生产环境中要添加完善的错误处理、日志记录和安全防护措施。
