Here's what I coded. It's not a patch, just code you're welcome to,
but it's probably much like yours.
private void setupMultipartRequest(final DocumentRequest request,
final ObjectWriter finalWriter, HttpPost post) {
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMimeSubtype("mixed");
builder.setMode(HttpMultipartMode.STRICT);
FormBodyPartBuilder partBuilder = FormBodyPartBuilder.create("request",
// Make sure we're not mislead by someone who puts a
charset into the mime type.
new
AbstractContentBody(ContentType.parse(ContentType.APPLICATION_JSON.getMimeType()))
{
@Override
public String getFilename() {
return null;
}
@Override
public void writeTo(OutputStream out) throws IOException {
finalWriter.writeValue(out, request);
}
@Override
public String getTransferEncoding() {
return MIME.ENC_BINARY;
}
@Override
public long getContentLength() {
return -1;
}
});
// Either one of 'name=' or 'Content-ID' would be enough.
partBuilder.setField(MIME.CONTENT_DISPOSITION, "inline;name=\"request\"");
partBuilder.setField("Content-ID", "request");
builder.addPart(partBuilder.build());
partBuilder = FormBodyPartBuilder.create("content", new
InputStreamBody(request.getContentBytes(),
ContentType.parse(request.getContentType())));
partBuilder.setField(MIME.CONTENT_DISPOSITION, "inline;name=\"content\"");
partBuilder.setField("Content-ID", "content");
builder.addPart(partBuilder.build());
builder.setCharset(StandardCharsets.UTF_8);
HttpEntity entity = builder.build();
post.setEntity(entity);
}
