Yii2 Raw File Parser

RawFileParser is a Yii2 extension that allows you to parse the content of requests that contain a raw file based on the Content-Type header. It does this by making the file available in the $_FILES array, allowing to handle it as a regular file upload.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist daxslab/yii2-rawfileparser "*"

or add

"daxslab/yii2-rawfileparser": "*"

to the require section of your composer.json file.

Configuration

In order to enable this parser you should configure [[Request::parsers]] in the following way:

return [
    'components' => [
        'request' => [
            'parsers' => [
                'application/zip' => [
                    'class' => 'daxslab\extensions\RawFileParser',
                    'basename' => 'azipfile' //optional but recommended, the name to locate the file in $_FILES
                ],
                'video/x-matroska' => 'daxslab\extensions\RawFileParser', //basename is not specified, the key $_FILES is a md5 hash of the file content. Ugly, yes...
            ],
        ],
        // ...
    ],
    // ...
];

Usage

Note: in order to the parser to be able to work:

1. The request must have the Content-Type header set to to specified value in the parser configuration
2. Yii::$app->request->getBodyParams() or Yii::$app->request->post() must be called previous to any attemp to access the file because is when the parser logic is executed.

Handling the uploaded file

Yii::$app->request->getBodyParams(); //parser is executed here, the file is on $_FILES now.
$uploadedFile = UploadedFile::getInstanceByName('azipfile');

if (!$uploadedFile) {
     throw new ServerErrorHttpException(Yii::t('app', 'No file uploaded'));
}

$uploadedFile->saveAs("/path/to/save/$uploadedFile->name");
