Getting size of request

[cobo lus]

hi !

i want to process a ITI-41 request and would like to know how big the request is in bytes before I store the documents to disk. Is there a way to get the content length ?

Hi,

You can simply count the bytes in the document input stream:

final ProvideAndRegisterDocumentSet request = Exchanges.getBody(exchange, ProvideAndRegisterDocumentSet.class);

final InputStream fileInputStream = request.getDocuments().get(0).getDataHandler().getInputStream();

final long documentSize;

try (final CountingOutputStream counter = new CountingOutputStream(new NullOutputStream())) {

    int b;

    while ((b = fileInputStream.read()) != -1) {

        counter.write(b);

    }

    documentSize = counter.getByteCount();

}

Kind regards,

Quentin

... and sometimes the content-length header ist present.
