middleware 速率限制器附加到路由或路由组即可throttle 中间件第一个参数是频率(次),第二个参数是时间(分钟)。下面代码块表示 1 分钟最多请求 10 次
Route::get('info', [UserController::class, 'info'])->middleware(['throttle:10,1']);
如果我们在设定的分钟数内请求次数超过了我们设定的频率次数,则会返回如下:
改造
如果我们想要得到 JSON 响应而不是得到一个 HTML,我们可以这样进行操作:
1、在 App\Http\Middleware
目录下创建新的中间件 ThrottleRequests
php artisan make:middleware ThrottleRequests
2、将 \Illuminate\Routing\Middleware\ThrottleRequests
内容复制到 \App\Http\Middleware\ThrottleRequests
内,并修改:
use App\Helpers\ResponseEnum;
use ApiResponse;
protected function handleRequest($request, Closure $next, array $limits)
{
foreach ($limits as $limit) {
if ($this->limiter->tooManyAttempts($limit->key, $limit->maxAttempts)) {
// 此处为修改后的自定义响应
$this->throwBusinessException(ResponseEnum::HTTP_ERROR, '操作频繁');
// throw $this->buildException($request, $limit->key, $limit->maxAttempts, $limit->responseCallback);
}
$this->limiter->hit($limit->key, $limit->decayMinutes * 60);
}
$response = $next($request);
foreach ($limits as $limit) {
$response = $this->addHeaders(
$response,
$limit->maxAttempts,
$this->calculateRemainingAttempts($limit->key, $limit->maxAttempts)
);
}
return $response;
}
3、修改 App\Http
路由中间件 $routeMiddleware
中的 throttle
'throttle' => \App\Http\Middleware\ThrottleRequests::class,
4、测试一下,当我们访问频率大于设定的次数时会返回:
{
"status": "fail",
"code": 200302,
"message": "操作频繁",
"data": null,
"error": null
}
