Hi,
i want to implement an multipart upload for Google Drive to do something
like this [1]:
POST /upload/drive/v2/files?uploadType=multipart HTTP/1.1
Host: www.googleapis.com
Authorization: Bearer your_auth_token
Content-Type: multipart/related; boundary="foo_bar_baz"
Content-Length: number_of_bytes_in_entire_request_body
--foo_bar_baz
Content-Type: application/json; charset=UTF-8
{
"title": "My File"
}
--foo_bar_baz
Content-Type: image/jpeg
JPEG data
--foo_bar_baz--
I build the header correctly but the content is my issue. So my first Step
was to implement the method call in my DriveAsyncClient:
@Named("Files:insert")
@POST
@OAuthScopes(DriveConstants.DRIVE_SCOPE)
@Path("upload/drive/v2/files")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@ResponseParser(ParseObjectFrom.class)
ListenableFuture<DriveResponseUpload> putContentAndMetadata
(@BinderParam(BindUploadMetadataToContent.class) DriveObject object,
@QueryParam(value = "uploadType") String uploadType);
Next Step was to implement the BindUploadMetadataToContent and so i had to
try out the MultiPartForm like this one:
@Override
public <R extends HttpRequest> R bindToRequest(R request, Object input) {
checkArgument(checkNotNull(input, "input") instanceof
DriveObject, "this binder is only valid for DriveObject");
DriveObject obj = DriveObject.class.cast(input);
Part.PartOptions contentOptions = new
Part.PartOptions().contentType(obj.getMetadata().getContentMetadata().getContentType());
contentOptions.filename(obj.getMetadata().getTitle());
Part content = Part.create(obj.getMetadata().getTitle(),
obj.getPayload(), contentOptions);
Part contentMetadata = Part.create(/*Content Metadata like Title*/);
request.setPayload(new MultipartForm("foo_bar_baz", content,
contentMetadata));
return request
}
The Question is, does the MultipartForm class still works and where is the
mistake?
Cheers,
Josh
