When this HLet accepts multipart requests, this method must return
a parts acceptor that will process the different parts.
An example of part acceptor is:
class ImageUpload extends HSimpleLet { class ImagePartsAcceptor(reqInfo: HReqHeaderData) extends HPartsAcceptor(reqInfo) { // the parts are stored in a byte array output stream private var input: ByteArrayOutputStream = _ // accept only uploaded image files def open(desc: HPartDescriptor) = reqInfo.header("Content-Type") match { case Some(mime) if mime.startsWith("image/") => input = new ByteArrayOutputStream true case _ => false } def accept(bytes: Array[Byte]) = { // write part into the buffer input.write(bytes) // accept more parts true } def close { // save the bytes containing the image image = Some(input.toByteArray) // close the output stream input.close input = null } def declineAll { input = null } } private var image: Option[Array[Byte]] = None def act(talk: HTalk) = { val response = image match { case Some(img) => "Image uploaded" case None => "Not uploaded Image" } talk.setContentLength(response.length).write(response) } }
