系統架構

本系統主要分為兩個部分「使用者建立訂單」與「查詢訂單內容」。前者為使用者隨機亂數選擇商品、亂數產生數量，並且新增一筆訂單，主要作用於測試寫入的部分，分別測試 10 個連線 300 次連續點擊、100 個連線 600 次連續點擊、300 個連線 1500 次連續點擊。而後者則為查找歷史訂單資訊，並且將資料結果顯示出來，主要作用於測試讀取的部分，單獨測試 300 個連線 1500 次連續點擊。

1. 使用者建立訂單

使用者建立訂單主要作用於測試寫入的部分，路由器(Router)去指定一個控制器(Controller)，事件作用隨機從使用者當中抽選一名使用者、隨機抽選數個商品，並且建立訂單。

首先路由器(Router)的部分，指定 /testing/v1/shopping 為主要負責處理建立訂單的控制器(Controller)，另外指定 /testing/v1/shopping/delete 為主要負責處理建立訂單，建立完畢後自動刪除資料的控制器(Controller)。

/*
 * Shopping Testing Controllers
 * All route names are prefixed with 'frontend.testing'.
 */
Route::group([
    'prefix' => 'testing',
    'as' => 'testing.',
], function () {
    /**
     * All route names are prefixed with 'frontend.testing.v1'.
     */
    Route::group([
        'prefix' => 'v1',
        'as' => 'v1.',
    ], function () {
        Route::get('shopping', [ShoppingV1Controller::class, 'shopping'])
            ->name('shopping');

        Route::get('shopping/delete', [ShoppingV1Controller::class, 'shoppingDelete'])
            ->name('shopping.delete');
    });
});

控制器(Controller)的部分，主要撰寫 shopping 負責處理建立訂單的事件，以及 shoppingDelete 負責處理建立訂單並刪除的事件。

/**
 * @var OrderService
 */
protected $orderService;

/**
 * @var ProductService
 */
protected $productService;

/**
 * ShoppingV1Controller constructor.
 *
 * @param OrderService $orderService
 * @param ProductService $productService
 */
public function __construct(OrderService $orderService, ProductService $productService)
{
    $this->orderService = $orderService;
    $this->productService = $productService;
}

/**
 * @return \Illuminate\View\View
 */
public function shopping()
{
    $order = $this->createOrder();

    return view('frontend.order.index-v1')
        ->with('order', $order)
        ->with('items', $order->items);
}

/**
 * @return \Illuminate\View\View
 */
public function shoppingDelete()
{
    $order = $this->createOrder();
    $items = $order->items;

    $this->orderService->delete($order);
    $this->orderService->destroy($order);

    return view('frontend.order.index-v1')
        ->with('order', $order)
        ->with('items', $items);
}

/**
 * @param array $data
 *
 * @return Orders
 */
protected function createOrder(): Orders
{
    $products = array();
    for ($i = 0; $i < mt_rand(1, 10); $i++) {
        $product = $this->productService->firstActive();
        if ($product->count >= 10) {
            array_push($products, array(
                'id' => $product->id,
                'count' => mt_rand(1, 10),
            ));
        } else {
            array_push($products, array(
                'id' => $product->id,
                'count' => mt_rand(1, $product->count),
            ));
        }
    }

    $order = $this->orderService->store(array(
        'model_id' => mt_rand(2, 11),
        'type' => Orders::UNPAID,
        'active' => true,
        'items' => $products,
    ));

    return $order;
}

最後將訂單結果回應給使用者，透過 frontend.order.index-v1 來撰寫其視圖(View)。

一整個流程建置完畢以後，這邊使用 ApacheBench 作為主要測試工具，首先會先測試 10 個連線 300 次連續點擊。

2. 查詢訂單內容

使用者查詢訂單內容主要作用於測試讀取的部分，路由器(Router)去指定一個控制器(Controller)，事件作用根據路由器(Router)所帶入的訂單 UUID 參數，去查找訂單內容，並且將訂單資訊回傳顯示。

首先路由器(Router)的部分，指定 /testing/v1/order/{order} 為主要負責處理查詢訂單的控制器(Controller)，其中 {order} 為訂單的 UUID 參數，系統會根據這個 UUID 參數來查找相對應的模型(Model)，並將其帶入到控制器(Controller)當中。

/*
 * Shopping Testing Controllers
 * All route names are prefixed with 'frontend.testing'.
 */
Route::group([
    'prefix' => 'testing',
    'as' => 'testing.',
], function () {
    /**
     * All route names are prefixed with 'frontend.testing.v1'.
     */
    Route::group([
        'prefix' => 'v1',
        'as' => 'v1.',
    ], function () {
        Route::get('order/{order}', [ShoppingV1Controller::class, 'order'])
            ->name('order');
    });
});

在控制器(Controller)直接將訂單資訊回傳給視圖(View)顯示。

/**
 * @param Orders $order
 *
 * @return \Illuminate\View\View
 */
public function order(Orders $order)
{
    return view('frontend.order.index-v1')
        ->with('order', $order)
        ->with('items', $order->items);
}

最後單獨測試 300 個連線 1500 次連續點擊，這裡可以明顯看到平均每秒可回應要求(Requests per second)比寫入的測試還小很多，由此得知比起資料讀取，資料的寫入更是需要優先處理並改善。
