Yii PSR-7 Download Response Factory

The package provides a factory to help forming file download PSR-7 response.

Requirements

• PHP 8.1 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/response-download

General usage

Use the factory to form a response:

use Psr\Http\Message\ResponseInterface;
use Yiisoft\ResponseDownload\DownloadResponseFactory;

final class MyController
{
    public function __construct(
        private readonly DownloadResponseFactory $downloadResponseFactory,
    )
    {    
    }

    public function sendMyContentAsFile(): ResponseInterface
    {
        return $this->downloadResponseFactory->sendContentAsFile('Hello!', 'message.txt');
    }
    
    public function sendMyFile(): ResponseInterface
    {
        return $this->downloadResponseFactory->sendFile('message.txt');
    }
    
    public function xSendMyFile(): ResponseInterface
    {
        return $this->downloadResponseFactory->xSendFile('message.txt');
    }
    
    public function sendMyStreamAsFile(): ResponseInterface
    {
        $stream = new MyStream();
        
        return $this->downloadResponseFactory->sendStreamAsFile($stream, 'message.txt');
    }
}

Note the xSendFile(). It is a special method that delegates the hard work to the web server instead of serving the file using PHP.

Optional arguments and defaults:

• If attachment name is not specified in sendFile() or xSendFile(), it will be taken from the name of the file
• served.
• Each file sending method could also be provided with optional mime type and optional content disposition.
• If mime type is omitted, for sendFile() and xSendFile() it will be determined based on the file content. For other methods or when unable to determine the mime type, "application/octet-stream" will be used.
• Content disposition is "attachment" by default. It will trigger browser's download dialog. If you want the content of the file to be displayed inline, set it to Yiisoft\Http\ContentDispositionHeader\ContentDispositionHeader::INLINE.
