How to use the Hyperf framework for request merging

With the development of the Internet and the increase in user needs, the number of requests in web applications is also increasing. In order to improve performance and efficiency, request merging has become an important technical means. In the Hyperf framework, we can easily implement the requested merge operation.

1. Project preparation
Before starting, make sure that the Hyperf framework has been installed and a new project has been created.

2. Create a service class for merge requests
First, we need to create a service class to handle merge requests. In the app/Service directory, create a file named RequestMergeService.

<?php

declare(strict_types=1);

namespace AppService;

use HyperfGuzzleClientFactory;
use HyperfUtilsApplicationContext;

class RequestMergeService
{
    public function sendRequests(array $urls): array
    {
        $client = $this->getClient();
        $promises = [];

        foreach ($urls as $url) {
            $promises[$url] = $client->getAsync($url);
        }

        $results = [];
        foreach ($promises as $url => $promise) {
            $response = $promise->wait();
            $results[$url] = $response->getBody()->getContents();
        }

        return $results;
    }

    private function getClient()
    {
        $container = ApplicationContext::getContainer();
        $factory = $container->get(ClientFactory::class);
        return $factory->create();
    }
}

3. Create a controller for merging requests
Next, we need to create a controller to receive the request and call the method in RequestMergeService to merge the request. In the app/Controller directory, create a file named RequestMergeController.

<?php

declare(strict_types=1);

namespace AppController;

use AppServiceRequestMergeService;
use HyperfHttpServerAnnotationController;
use HyperfHttpServerAnnotationGetMapping;
use HyperfDiAnnotationInject;

/**
 * @Controller
 * @GetMapping("/request/merge")
 */
class RequestMergeController
{
    /**
     * @Inject
     * @var RequestMergeService
     */
    private $requestMergeService;

    public function index()
    {
        $urls = [
            'http://example.com/api/user/1',
            'http://example.com/api/user/2',
            'http://example.com/api/user/3',
        ];

        $result = $this->requestMergeService->sendRequests($urls);

        return $result;
    }
}

4. Configure routing
Open the config/routes.php file and add the following routing configuration:

use AppControllerRequestMergeController;

Router::addRoute(['GET', 'POST', 'HEAD'], '/request/merge', [RequestMergeController::class, 'index']);

5. Test request merging
Start the Hyerpf project and use the browser Visit http://localhost:9501/request/merge to get the results of the merge request.

6. Summary
This article introduces how to use the Hyperf framework for request merging. By creating the RequestMergeService service class and the RequestMergeController controller, we can easily implement the request merging function. In this way, it can not only improve performance and reduce the number of requests, but also reduce network overhead and improve user experience.
