> Project: Olingo
> Issue Type: Bug
> Components: MISC, odata2-annotation, odata2-core, odata4-server
> Affects Versions: V2 2.0.3
> Reporter: Prashanth

> This question is about the support for attachments uploading and downloading
> via Olingo Service ( Olingo V2 2.0.3 ). I have gone the olingo docs but
> didn't find any clue on how to provide support for uploading and downloading
> of attachments using olingo .
> Does olingo supports this functionality ? If olingo supports , how to
> implements this ?
> Following are some basics which i came to know by debugging the core library :
> -> Media type support : We can provide support for custom content types by
> overriding the method getCustomContentTypes() in processor class.
> -> Implementation : we can implement createEntity as following in processor
> class :
> @Override
> public ODataResponse createEntity(PostUriInfo uriInfo, InputStream
> content,
> String requestContentType, String contentType) throws ODataException {
> ... }
>
> But here content is giving the requestBody , not actual file/attachment.
> Note : Here the support for attachments means - ex : in case of Rest , CXF
> provides some api which can be seen in following snippet :
> @POST
> @Consumes( {MediaType.MULTIPART_FORM_DATA })
> @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
> public Response create(@Context HttpHeaders httpHeaders, @Context
> UriInfo uriInfo,
> MultipartBody multipartBody)
> Here @Consumes media type provides consumption of multipart formdata and
> MultipartBody parameter can give us the attachments.
> Similar to above , Does Olingo V2 2.0.3 provides any API ?How can we
> implement the support for attachments in Olingo V2 2.0.3 ? Please share us an
> example !
