### Step 3: Test with Thumbnailer

We used [Thumbnailer](https://github.com/minio/thumbnailer) to listen for MinIO notifications when a new JPEG file is uploaded (HTTP PUT). Triggered by a notification, Thumbnailer uploads a thumbnail of new image to MinIO server. To start with, download and install Thumbnailer.

```
git clone https://github.com/minio/thumbnailer/
npm install
```

// MalformedUploadID malformed upload id.
type MalformedUploadID struct {

}

// InvalidUploadID invalid upload id.
type InvalidUploadID struct {

	Object   string
	UploadID string
}

func (e InvalidUploadID) Error() string {

Sie können auch `File()` mit `UploadFile` verwenden, um zum Beispiel zusätzliche Metadaten zu setzen:

{* ../../docs_src/request_files/tutorial001_03_an_py39.py hl[9,15] *}

## Mehrere Datei-Uploads { #multiple-file-uploads }

Es ist auch möglich, mehrere Dateien gleichzeitig hochzuladen.

Diese werden demselben Formularfeld zugeordnet, welches mit den Formulardaten gesendet wird.
