Yii2 xml file response

Question

I have xml file and I want to send it in my api action by http-response with Content-Type=multipart/form-data

Now I'm using Content-Type=text/xml and my action looks like

\Yii::$app->response->format = \yii\web\Response::FORMAT_RAW;
$headers = \Yii::$app->response->headers;
$headers->add('Content-Type', 'text/xml');
$xml = file_get_contents($filePath);

return $xml;

But it is not exactly what I want. How can I change this response to Content-Type=multipart/form-data ?

Answer 1

You can change the Content-Type for the response by customizing the XmlResponseFormatter components property contentType to use custom value and then setting the custom formatter on runtime rather than using echo manually as since 2.0.14 Yii does not allow echoing in the controller, hence should not be followed. Also using this method will set the charset too for the content-type headers automatically.

You should do the following to follow a conventional approach

public function actionResponder()
{
    $filePath = $_SERVER['DOCUMENT_ROOT'] . '/assets/test.xml';

    $xml = new XmlResponseFormatter();
    $xml->contentType = 'multipart/form-data';
    Yii::$app->response->format='xml';
    Yii::$app->response->formatters['xml']=$xml;

    $xmlFile = file_get_contents($filePath);

    return $xmlFile;
}

Answer 2

You can send response with custom content type in this way:

Yii::$app->response->format = Response::FORMAT_RAW;
Yii::$app->response->headers->add('Content-Type', 'multipart/form-data');
Yii::$app->response->content = file_get_contents($filePath);
return Yii::$app->response;
