How to use the Hyperf framework to generate QR codes

Introduction:

With the widespread application of QR codes, there is a need for QR code generation More and more. As a high-performance PHP framework, the Hyperf framework provides many convenient and fast expansion capabilities, including QR code generation. This article will introduce how to use the Hyperf framework to generate QR codes, and attach specific code examples.

1. Install dependencies

Before we start, we need to install several dependency packages.

1. Use Composer to install the endroid/qr-code package:

composer require endroid/qr-code

2. Add for Hyperf in config/autoload/annotations.php Annotation support:

<?php

declare(strict_types=1);

use HyperfDiAnnotationScan;

return [
    'scan' => [
        Scan::class => [
            'paths' => [
                BASE_PATH . '/app',
            ],
            'ignore_annotations' => [
            ],
            'enable_scan_cache' => env('ENABLE_ANNOTATION_CACHE', true),
            'cache_key' => 'annotations',
            'exclude' => [],
            'proxy' => [
                'auto_generate' => true,
                'dir' => BASE_PATH . '/runtime/container/proxy',
                'namespace' => 'App\Proxy',
                'overwrite' => false,
            ],
        ],
    ],
];

2. Create a controller

In the Hyperf framework, we use controllers to handle HTTP requests. Next we create a QrCodeController for generating QR codes.

<?php

declare(strict_types=1);

namespace AppController;

use HyperfHttpServerAnnotationController;
use HyperfHttpServerAnnotationRequestMapping;
use HyperfHttpServerContractResponseInterface;
use EndroidQrCodeResponseQrCodeResponse;
use EndroidQrCodeQrCode;

/**
 * @Controller(prefix="/qrcode")
 */
class QrCodeController
{
    /**
     * @RequestMapping(path="/generate", methods="get")
     */
    public function generate(ResponseInterface $response)
    {
        $qrCode = new QRCode('https://www.example.com');
        
        return $response->withAddedHeader('Content-Type', QrCodeResponse::class)->withBody(new SwooleStream($qrCode->writeString()));
    }
}

3. Configure routing

Add the defined routing information in config/routes.php.

<?php

declare(strict_types=1);

use HyperfHttpServerRouterRouter;

Router::get('/qrcode/generate', 'AppControllerQrCodeController@generate');

4. Test to generate QR code

Start the Hyperf framework and visit http://localhost:9501/qrcode/generate to generate a code containing https://www.example.comThe QR code of the link.

Summary:

This article introduces how to use the Hyperf framework to generate QR codes. By installing dependency packages, creating controllers and configuring routes, we can easily generate QR codes in the Hyperf framework. hope that it can help us.
