第二章:Laravel电商金字塔架构模型
2.1 基础层:数据存储与缓存架构
多数据库设计:
php
// config/database.php
'connections' => [
'user_center' => [ // 用户中心
'read' => ['host' => ['192.168.1.10', '192.168.1.11']],
'write' => ['host' => '192.168.1.12']
],
'product_center' => [ // 商品中心
'read' => ['host' => ['192.168.1.20', '192.168.1.21']],
'write' => ['host' => '192.168.1.22']
],
'order_center' => [ // 订单中心
'read' => ['host' => ['192.168.1.30', '192.168.1.31']],
'write' => ['host' => '192.168.1.32']
]
]
商品SKU数据模型:
php
class Product extends Model
{
// 商品基本属性
public function skus() {
return $this->hasMany(ProductSku::class);
}
public function categories() {
return $this->belongsToMany(Category::class);
}
public function attributes() {
return $this->hasMany(ProductAttribute::class);
}
}
class ProductSku extends Model
{
public function product() {
return $this->belongsTo(Product::class);
}
// SKU属性组合
public function attributes() {
return $this->belongsToMany(ProductAttribute::class, 'sku_attribute');
}
// 库存检查
public function decreaseStock($amount) {
if ($amount < 0) {
throw new InternalException('减库存不可小于0');
}
return $this->where('id', $this->id)
->where('stock', '>=', $amount)
->decrement('stock', $amount);
}
}
2.2 核心层:业务服务架构
领域驱动设计实现:
app/
├── Domains/
│ ├── User/ # 用户领域
│ │ ├── Services/
│ │ │ ├── UserService.php
│ │ │ └── AddressService.php
│ │ └── Repositories/
│ ├── Product/ # 商品领域
│ │ ├── Services/
│ │ │ ├── ProductService.php

│ │ └── Repositories/
│ └── Promotion/ # 营销领域
│ ├── Services/
│ │ ├── CouponService.php
│ │ └── DiscountService.php
│ └── Repositories/
购物车服务实现:
php
class CartService
{
public function add($userId, $skuId, $amount)
{
// 检查商品是否存在且有库存
$sku = ProductSku::find($skuId);
if (!$sku) {
throw new InvalidRequestException('该商品不存在');
}
if (!$sku->product->on_sale) {
throw new InvalidRequestException('该商品未上架');
}
if ($sku->stock === 0) {
throw new InvalidRequestException('该商品已售完');
}
if ($amount > $sku->stock) {
throw new InvalidRequestException('该商品库存不足');
}
// 检查购物车中是否已存在该商品
$cart = Cart::where('user_id', $userId)
->where('product_sku_id', $skuId)
->first();
if ($cart) {
$cart->update(['amount' => $cart->amount + $amount]);
} else {
Cart::create([
'user_id' => $userId,
'product_sku_id' => $skuId,
'amount' => $amount
]);
}
}
public function getCartItems($userId)
{
return Cart::with(['sku.product'])
->where('user_id', $userId)
->get()
->filter(function ($cart) {
return $cart->sku->product->on_sale;
});
}
}
2.3 集成层:第三方服务架构
支付服务集成:
php
class PaymentService
{
public function pay(Order $order, $paymentMethod)
{
switch ($paymentMethod) {
case 'alipay':
return $this->alipay($order);
case 'wechat':
return $this->wechatPay($order);
case 'unionpay':
return $this->unionPay($order);
default:
throw new InvalidRequestException('支付方式不支持');
}
}
protected function alipay(Order $order)
{
$alipay = app('alipay');
return $alipay->web([
'out_trade_no' => $order->no,
'total_amount' => $order->total_amount,
'subject' => '支付订单:'.$order->no,
]);
}
}
// 支付宝回调处理
class AlipayController extends Controller
{
public function return()
{
try {
app('alipay')->verify();
} catch (\Exception $e) {
return view('pages.error', ['msg' => '数据不正确']);
}
return view('pages.success', ['msg' => '付款成功']);
}
public function notify()
{
$data = app('alipay')->verify();
// 如果订单状态不是成功或者结束,则校验订单真实性
if (!in_array($data->trade_status, ['TRADE_SUCCESS', 'TRADE_FINISHED'])) {
return app('alipay')->success();
}
$order = Order::where('no', $data->out_trade_no)->first();
if (!$order) {
return 'fail';
}
// 如果订单已支付
if ($order->paid_at) {
return app('alipay')->success();
}
// 更新订单状态
$order->update([
'paid_at' => Carbon::now(),
'payment_method' => 'alipay',
'payment_no' => $data->trade_no,
]);
return app('alipay')->success();
}
}
物流查询服务:
php
class ShippingService
{
public function track($order)
{
$shipping = $order->shipping;
if (!$shipping || !$shipping->tracking_number) {
return null;
}
$cacheKey = 'shipping_track:'.$shipping->tracking_number;
return Cache::remember($cacheKey, 300, function () use ($shipping) {
$client = new ShippingClient(config('services.shipping.key'));
return $client->track($shipping->tracking_number, $shipping->company);
});
}
}
2.4 表现层:API与前端架构
API资源设计:
php
class ProductResource extends JsonResource
{
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'description' => $this->description,
'image' => $this->image,
'price' => $this->price,
'original_price' => $this->original_price,
'stock' => $this->stock,
'on_sale' => $this->on_sale,
'rating' => $this->rating,
'review_count' => $this->review_count,
'skus' => ProductSkuResource::collection($this->whenLoaded('skus')),
'attributes' => ProductAttributeResource::collection($this->whenLoaded('attributes')),
'created_at' => $this->created_at->toDateTimeString(),
'updated_at' => $this->updated_at->toDateTimeString(),
];
}
}
class OrderResource extends JsonResource
{
public function toArray($request)
{
return [
'id' => $this->id,
'no' => $this->no,
'total_amount' => $this->total_amount,
'remark' => $this->remark,
'paid_at' => $this->paid_at ? $this->paid_at->toDateTimeString() : null,
'payment_method' => $this->payment_method,
'payment_no' => $this->payment_no,
'ship_status' => $this->ship_status,
'ship_data' => $this->ship_data,
'created_at' => $this->created_at->toDateTimeString(),
'items' => OrderItemResource::collection($this->whenLoaded('items')),
'address' => new OrderAddressResource($this->whenLoaded('address')),
];
}
}
第三章:核心业务模块深度实现
3.1 订单处理系统
订单创建与库存扣减:
php
class OrderService
{
public function store($user, $addressId, $remark, $items)
{
return DB::transaction(function () use ($user, $addressId, $remark, $items) {
// 获取地址信息
$address = UserAddress::find($addressId);
// 创建订单号
$orderNo = $this->generateOrderNo();
// 创建订单
$order = Order::create([
'no' => $orderNo,
'user_id' => $user->id,
'address' => [
'address' => $address->full_address,
'zip' => $address->zip,
'contact_name' => $address->contact_name,
'contact_phone' => $address->contact_phone,
],
'remark' => $remark,
'total_amount' => 0,
]);
$totalAmount = 0;
// 遍历用户提交的SKU
foreach ($items as $data) {
$sku = ProductSku::find($data['sku_id']);
// 创建订单项
$item = $order->items()->make([
'amount' => $data['amount'],
'price' => $sku->price,
]);
$item->product()->associate($sku->product_id);
$item->productSku()->associate($sku);
$item->save();
$totalAmount += $sku->price * $data['amount'];
// 减库存
if ($sku->decreaseStock($data['amount']) <= 0) {
throw new InvalidRequestException('该商品库存不足');
}
}
// 更新订单总金额
$order->update(['total_amount' => $totalAmount]);
// 将下单的商品从购物车中移除
$skuIds = collect($items)->pluck('sku_id');
Cart::where('user_id', $user->id)
->whereIn('product_sku_id', $skuIds)
->delete();
return $order;
});
}
protected function generateOrderNo()
{
// 订单号生成规则
return date('YmdHis').str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT);
}
}
3.2 优惠券系统
优惠券核销逻辑:
php
class CouponService
{
public function checkCoupon($user, $couponCode, $orderAmount = null)
{
// 查询优惠券
$coupon = Coupon::where('code', $couponCode)->first();
if (!$coupon) {
throw new CouponCodeUnavailableException('优惠券不存在');
}
$coupon->checkAvailable($user, $orderAmount);
return $coupon;
}
}
class Coupon extends Model
{
public function checkAvailable($user, $orderAmount = null)
{
if (!$this->enabled) {
throw new CouponCodeUnavailableException('优惠券不存在');
}
if ($this->total - $this->used <= 0) {
throw new CouponCodeUnavailableException('该优惠券已被兑完');
}
if ($this->not_before && $this->not_before->gt(Carbon::now())) {
throw new CouponCodeUnavailableException('该优惠券现在还不能使用');
}
if ($this->not_after && $this->not_after->lt(Carbon::now())) {
throw new CouponCodeUnavailableException('该优惠券已过期');
}
if (!is_null($orderAmount) && $orderAmount < $this->min_amount) {
throw new CouponCodeUnavailableException('订单金额不满足该优惠券最低金额');
}
$used = Order::where('user_id', $user->id)
->where('coupon_code_id', $this->id)
->where(function($query) {
$query->where(function($query) {
$query->whereNull('paid_at')
->where('closed', false);
})->orWhere(function($query) {
$query->whereNotNull('paid_at')
->where('refund_status', '!=', RefundRequest::REFUND_STATUS_SUCCESS);
});
})->exists();
if ($used) {
throw new CouponCodeUnavailableException('你已经使用过这张优惠券了');
}
}
public function getAdjustedPrice($orderAmount)
{
// 固定金额
if ($this->type === self::TYPE_FIXED) {
return max(0.01, $orderAmount - $this->value);
}
// 百分比折扣
return number_format($orderAmount * (100 - $this->value) / 100, 2, '.', '');
}
}
3.3 搜索服务实现
Elasticsearch集成:
php
class ProductSearchService
{
public function search($query, $filters, $sort, $page, $perPage)
{
$params = [
'index' => 'products',
'body' => [
'from' => ($page - 1) * $perPage,
'size' => $perPage,
'query' => $this->buildQuery($query, $filters),
'sort' => $this->buildSort($sort)
]
];
$results = $this->elasticsearch->search($params);
return $this->buildResults($results);
}
protected function buildQuery($query, $filters)
{
$boolQuery = ['bool' => ['must' => []]];
// 关键词搜索
if ($query) {
$boolQuery['bool']['must'][] = [
'multi_match' => [
'query' => $query,
'fields' => ['title^3', 'description^2', 'tags^2']
]
];
}
// 过滤器
foreach ($filters as $field => $value) {
if (!is_null($value)) {
$boolQuery['bool']['filter'][] = ['term' => [$field => $value]];
}
}
return $boolQuery;
}
}
第四章:高性能优化策略
4.1 缓存架构设计
多级缓存策略:
php
class ProductCacheService
{
public function getProductWithCache($productId)
{
$cacheKey = "product:{$productId}";
return Cache::remember($cacheKey, 3600, function () use ($productId) {
return Product::with(['skus', 'attributes', 'categories'])
->find($productId);
});
}
public function getHotProducts($limit = 10)
{
$cacheKey = "hot_products:{$limit}";
return Cache::remember($cacheKey, 300, function () use ($limit) {
return Product::where('on_sale', true)
->orderBy('sold_count', 'desc')
->limit($limit)
->get();
});
}
}
4.2 数据库优化
索引优化方案:
php
// 数据库迁移文件
Schema::table('products', function (Blueprint $table) {
$table->index(['on_sale', 'rating', 'sold_count']);
$table->index(['category_id', 'on_sale']);
$table->fullText(['title', 'description', 'tags']);
});
Schema::table('orders', function (Blueprint $table) {
$table->index(['user_id', 'created_at']);
$table->index(['paid_at', 'ship_status']);
$table->index('no');
});
查询优化技巧:
php
class ProductRepository
{
public function getProductsWithOptimizedQuery($categoryId = null, $orderBy = 'id', $sort = 'desc')
{
return Product::query()
->with(['skus' => function ($query) {
$query->select('id', 'product_id', 'price', 'stock')
->where('stock', '>', 0);
}])
->when($categoryId, function ($query, $categoryId) {
$query->whereHas('categories', function ($query) use ($categoryId) {
$query->where('id', $categoryId);
});
})
->where('on_sale', true)
->orderBy($orderBy, $sort)
->select(['id', 'title', 'image', 'rating', 'sold_count', 'price'])
->paginate(16);
}
}
4.3 队列异步处理
订单相关异步任务:
php
class ProcessOrderAfterPaid implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $order;
public function __construct(Order $order)
{
$this->order = $order;
}
public function handle()
{
// 更新商品销量
foreach ($this->order->items as $item) {
$product = $item->product;
$product->increment('sold_count', $item->amount);
}
// 发送订单邮件通知
Mail::to($this->order->user->email)
->queue(new OrderPaid($this->order));
// 如果使用了优惠券,更新优惠券使用量
if ($this->order->couponCode) {
$this->order->couponCode->increment('used');
}
}
}
第五章:安全与风控体系
5.1 支付安全
支付签名验证:
php
class PaymentSecurityService
{
public function verifyWechatSign($data, $sign)
{
ksort($data);
$string = $this->toUrlParams($data);
$string .= '&key='.config('services.wechat.key');
return strtoupper(md5($string)) === $sign;
}
public function verifyAlipaySign($data)
{
$alipayPublicKey = config('services.alipay.alipay_public_key');
$sign = $data['sign'];
unset($data['sign'], $data['sign_type']);
ksort($data);
$string = $this->toUrlParams($data);
return openssl_verify(
$string,
base64_decode($sign),
$alipayPublicKey,
OPENSSL_ALGO_SHA256
) === 1;
}
}
5.2 防刷单机制
订单频率限制:
php
class OrderRateLimitMiddleware
{
public function handle($request, $next)
{
$user = $request->user();
$key = 'order_rate_limit:'.$user->id;
$maxAttempts = 10; // 10分钟内最多10单
$decayMinutes = 10;
if (RateLimiter::tooManyAttempts($key, $maxAttempts)) {
$seconds = RateLimiter::availableIn($key);
throw new TooManyRequestsException('操作过于频繁,请'.ceil($seconds/60).'分钟后再试');
}
RateLimiter::hit($key, $decayMinutes * 60);
return $next($request);
}
}
第六章:部署与监控
6.1 生产环境配置
环境变量配置:
php
// .env.production
APP_ENV=production
APP_DEBUG=false
# 数据库配置
DB_READ_HOST=192.168.1.10,192.168.1.11
DB_WRITE_HOST=192.168.1.12
# Redis集群
REDIS_CLUSTER=redis
REDIS_HOST=192.168.1.20,192.168.1.21,192.168.1.22
# 队列配置
QUEUE_CONNECTION=redis
# 缓存配置
CACHE_DRIVER=redis
6.2 健康检查与监控
监控端点设计:
php
Route::get('/health', function () {
$checks = [
'database' => DB::connection()->getPdo() ? 'healthy' : 'unhealthy',
'redis' => Redis::ping() ? 'healthy' : 'unhealthy',
'storage' => $this->checkStorage(),
'queue' => $this->checkQueueWorker()
];
$status = collect($checks)->contains('unhealthy') ? 503 : 200;
return response()->json([
'status' => $status == 200 ? 'healthy' : 'unhealthy',
'timestamp' => now()->toISOString(),
'checks' => $checks
], $status);
});
