How to use the Hyperf framework for file upload requires specific code examples

Introduction:
With the development of web applications, the file upload function has become a part of many projects an essential part. Hyperf is a high-performance PHP microservice framework that provides a rich set of functions, including file upload. This article will introduce how to use the Hyperf framework for file upload and give specific code examples.

1. Install the Hyperf framework:
First, you need to install the Hyperf framework. It can be installed through the composer command:

composer create-project hyperf/hyperf-skeleton

After the installation is completed, enter the project directory and start Hyperf:

cd hyperf-skeleton
php bin/hyperf.php start

2. Write the file upload interface:
In the Hyperf framework, we can write Controller to handle the request. Create a new UploadController.php file and add the following code:

<?php

declare(strict_types=1);

namespace AppController;

use HyperfHttpServerAnnotationAutoController;
use HyperfHttpServerContractRequestInterface;
use HyperfHttpServerContractResponseInterface;
use HyperfHttpServerHttpServer;
use HyperfHttpServerRouterDispatched;
use HyperfHttpServerRouterHandler;
use HyperfHttpServerRouterRouteCollector;
use HyperfHttpServerRouterRouter;
use HyperfUtilsCodecJson;
use HyperfUtilsContext;
use PsrHttpMessageResponseInterface as Psr7ResponseInterface;

/**
 * @AutoController()
 */
class UploadController extends AbstractController
{
    /**
     * 文件上传
     */
    public function upload(RequestInterface $request): Psr7ResponseInterface
    {
        $file = $request->file('file');  // 获取上传的文件
        $uploadedPath = $file->getPath();  // 获取上传的文件的临时路径
        $filename = $file->getClientFilename();  // 获取上传的文件名
        
        // 处理上传的文件，例如保存到指定目录
        $targetPath = BASE_PATH . '/public/uploads/' . $filename;
        $file->moveTo($targetPath);
        
        return $this->success('文件上传成功');
    }
}

3. Configure routing:
In the Hyperf framework, we need to configure routing to map requests to the corresponding Controller for processing. Open the config/routes.php file and add the following code:

<?php

use HyperfHttpServerRouterRouter;

Router::addRoute(
    ['POST'],
    '/upload',
    'AppControllerUploadController@upload'
);

4. Call the file upload interface:
In the front-end page, you can upload files through a form. Configure the form's action to /upload and set the enctype to multipart/form-data. The following is a simple HTML example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>文件上传示例</title>
</head>
<body>
    <form action="/upload" method="POST" enctype="multipart/form-data">
        <input type="file" name="file">
        <input type="submit" value="上传">
    </form>
</body>
</html>

5. Test file upload:
After starting the Hyperf server, open the browser and enter http://localhost:9501 in the address bar , enter the file upload page. Select a file and click the upload button to complete the file upload.

Conclusion:
Through the file upload function provided by the Hyperf framework, we can easily realize the file upload requirements.
