Description

Attached file is misinterpreted as being a matlab file when it's really just a minimised javascript file.

Using:

private final DefaultDetector mimeTypeDetector = new DefaultDetector();

public String determineMimeType(final byte[] data, final String fileName) {
    final TikaInputStream inputStream = TikaInputStream.get(data);
    final Metadata metadata = new Metadata();
    metadata.set(Metadata.RESOURCE_NAME_KEY, fileName);
    try {
        return mimeTypeDetector.detect(inputStream, metadata).toString();
    } catch (final IOException e) {
        throw new ApiException(e);
    }
}
