php - 用于 Laravel 5.6 中 api 路由的 ThrottleRequestMiddleware

Question

我已经构建了用于将帖子作为 json 资源返回的 api 路由，当我将中间件 'apiThrottle:5,1' 放在 api 路由上时，它只显示两次结果，然后在第三次中它会生成 json 响应 'Too多次尝试……”

但是，当我将中间件添加到网络路由时，它将继续显示最大次数的结果(在本例中为 5)，然后它会生成“尝试次数过多...”

网址:https://project.test/

Route::middleware('apiThrottle:5,1')->get('/', function (){
     return 'Web Route';
});

Api 路由: https://project.test/api/

Route::middleware('apiThrottle:5,1')->get('/', function (){
     return 'API Route';
});

中间件:

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\JsonResponse;
use Illuminate\Routing\Middleware\ThrottleRequests;

class ThrottleRequestsMiddleware extends ThrottleRequests
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request $request
     * @param  \Closure $next
     * @param  int $maxAttempts
     * @param  int $decayMinutes
     * @return mixed
     */
    public function handle($request, Closure $next, $maxAttempts = 60, $decayMinutes = 1)
    {
        $key = $this->resolveRequestSignature($request);

        $maxAttempts = $this->resolveMaxAttempts($request, $maxAttempts);

        if ($this->limiter->tooManyAttempts($key, $maxAttempts)) {
            return $this->buildJsonResponse($key, $maxAttempts);
        }

        $this->limiter->hit($key, $decayMinutes);

        $response = $next($request);

        return $this->addHeaders(
            $response, $maxAttempts,
            $this->calculateRemainingAttempts($key, $maxAttempts)
        );
    }

    /**
     * Create a 'too many attempts' JSON response.
     *
     * @param  string  $key
     * @param  int  $maxAttempts
     * @return \Symfony\Component\HttpFoundation\Response
     */
    protected function buildJsonResponse($key, $maxAttempts)
    {
        $response = new JsonResponse([
            'error' => [
                'code' => 429,
                'message' => 'Too many attempts, please slow down the request.',
            ],
        ], 429);

        $retryAfter = $this->limiter->availableIn($key);

        return $this->addHeaders(
            $response, $maxAttempts,
            $this->calculateRemainingAttempts($key, $maxAttempts, $retryAfter),
            $retryAfter
        );
    }
}

Kernel.php :

     /**
     * The application's route middleware.
     *
     * These middleware may be assigned to groups or used individually.
     *

Answer 1

api throttle 声明两次，因此命中计数两次。

对于所有 api 路由，在 上声明了 throttle 中间件app/Http/Kernel.php

    'api' => [
        'throttle:60,1',
        'bindings',
    ],

要解决此问题，您必须在内核文件中删除 api throttle ，您可以在 api 路由文件 中定义单独的节流中间件组。 app/routes/api.php 如下:

// limit to 60 hits in 1 min
Route::group(['middleware' => ['throttle:60,1'], 'prefix' => 'foo'], function () {
    Route::get('/', 'FooController@fooMethod');
});

// limit to 500 hits in 1 min
Route::group(['middleware' => ['throttle:500,1'], 'prefix' => 'bar'], function () {
    Route::get('/', 'BarController@barMethod');
});
