public final class UploadBlobServlet
extends HttpServlet
UploadBlobServlet
handles blob uploads in the development
server. The stub implementation of BlobstoreService.createUploadUrl(java.lang.String)
returns URLs that are mapped to this servlet.
Its primary responsibility is parsing multipart/form-data or multipart/mixed requests made by web browsers. To minimize dependencies in the SDK, it does using the MimeMultipart class included with JavaMail.
After the files are extracted from the multipart request body,
they are assigned BlobKey
values and are committed to local
storage. The multipart body parts are then replaced with
message/external-body parts that specify the BlobKey
as
additional parameters in the Content-type header.
