How to use the Hyperf framework to limit request flow
Introduction:
In modern Internet applications, how to ensure the stability of the system under high concurrency is very important. Request throttling is one of the common coping strategies. This article will introduce how to use the Hyperf framework to limit request flow and give specific code examples.
1. What is request current limiting?
Request current limiting refers to limiting the number of request visits to the system within a period of time to prevent the system from crashing due to too many requests. Through reasonable current limiting strategies, better service quality and stability can be provided. The Hyperf framework provides a variety of request flow limiting methods, including token bucket algorithm and leaky bucket algorithm.
2. How to use the Hyperf framework to implement request current limiting
- Install the Hyperf framework
First, you need to install the Hyperf framework. It can be installed through Composer. For specific installation steps, please refer to the official Hyperf documentation. - Add request current limiting middleware
In the Hyperf framework, request current limiting can be implemented through middleware. You can create a request flow limiting middleware through the following code:
declare(strict_types=1);
namespace AppMiddleware;
use HyperfDiAnnotationInject;
use HyperfHttpServerContractRequestInterface;
use HyperfHttpServerContractResponseInterface;
use HyperfRateLimitAnnotationRateLimit;
use HyperfRateLimitAspectRateLimitAspect;
?
class RequestLimitMiddleware
{
/**
* @Inject
* @var RequestInterface
*/
protected $request;
/**
* @Inject
* @var ResponseInterface
*/
protected $response;
public function process($request, $handler): ResponseInterface
{
// 獲取請求的IP地址
$ip = $this->request->getServerParams()['remote_addr'];
// 檢查IP是否在限流規(guī)則中
if (! $this->isRequestAllowed($ip)) {
$this->response->json(['message' => '請求過于頻繁，請稍后再試'], 429);
}
return $handler->handle($request);
}
/**
* 檢查請求是否允許
*/
protected function isRequestAllowed(string $ip): bool
{
// 這里可以根據(jù)具體的限流算法進(jìn)行實(shí)現(xiàn)，例如使用令牌桶算法或漏桶算法
// 返回true表示允許請求，返回false表示請求被限制
}}
In the above code, we annotate @RateLimit to identify that the interface needs to request current limiting, and specify the specific current limiting strategy. At the same time, we intercept the request in the middleware by determining whether the request is restricted.
Configuring parameters for request current limiting
In the configuration file config/autoload/middlewares.php of the Hyperf framework, you can configure parameters for requesting current limiting. For example, add the following parameters to the configuration file:
[
'http' => [// ... AppMiddlewareRequestLimitMiddleware::class => [ 'priority' => 99, 'rate' => 100, // 每秒最多100個(gè)請求 'capacity' => 100, // 令牌桶的容量為100 ], // ...],
]
In the above configuration, we can specify each The maximum number of requests allowed per second and the capacity of the token bucket. Specific configuration parameters can be adjusted according to actual needs.- Start the Hyperf framework
By running the Hyperf framework, the middleware will intercept and limit requests that exceed the set number of requests.
Conclusion:
This article introduces how to use the Hyperf framework to limit request flow, and gives specific code examples. In actual applications, it can be adjusted and expanded accordingly according to actual needs and business scenarios. Through reasonable request current limiting strategies, the stability and service quality of the system can be improved, providing users with a better user experience.
