how to convert to html use go-tika?

[imqishi]

in java api, we can convert file to html like this:

public static String extractHtml(File file) throws IOException {
    byte[] bytes = Files.toByteArray(file);
    AutoDetectParser tikaParser = new AutoDetectParser();
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    SAXTransformerFactory factory = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
    TransformerHandler handler;
    try {
        handler = factory.newTransformerHandler();
    } catch (TransformerConfigurationException ex) {
        throw new IOException(ex);
    }
    handler.getTransformer().setOutputProperty(OutputKeys.METHOD, "html");
    handler.getTransformer().setOutputProperty(OutputKeys.INDENT, "yes");
    handler.getTransformer().setOutputProperty(OutputKeys.ENCODING, "UTF-8");
    handler.setResult(new StreamResult(out));
    ExpandedTitleContentHandler handler1 = new ExpandedTitleContentHandler(handler);
    try {
        tikaParser.parse(new ByteArrayInputStream(bytes), handler1, new Metadata());
    } catch (SAXException | TikaException ex) {
        throw new IOException(ex);
    }
    return new String(out.toByteArray(), "UTF-8");
}

can go-tika do this? when we use

client := tika.NewClient(nil, s.URL())
body, err := client.Parse(context.Background(), f)

what is the body's content? or how to understand this return?

go-tika is based on Tika server: https://cwiki.apache.org/confluence/display/TIKA/TikaServer

So, we should be able to adjust go-tika to support any endpoint there. client.Parse corresponds to PUT /tika.

I'm just getting started using this and it looks like client.Parse will return HTML, I'm actually trying to get it to return text/plain but I don't seem to be able to find a way to pass a request header.
