hmmm
not working..
i don't know why..
i run this code:
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
Iterator<BlobInfo> iterator = new
BlobInfoFactory().queryBlobInfos();
while(iterator.hasNext()) {
BlobInfo b = iterator.next();
if (b.getFilename().equals("myfile.exe")) {
resp.setHeader("content-type", b.getContentType());
resp.setHeader("content-disposition", "attachment;
filename=" +
b.getFilename());
resp.setHeader("content-length", new
Long(b.getSize()).toString());
resp.setContentLength(new
Long(b.getSize()).intValue());
blobstoreService.serve(b.getBlobKey(),resp);
}
}
}
and got this response header (using firebug)
HTTP/1.1 200 OK
Content-Type: application/x-msdownload
Content-Disposition: attachment; filename=myfile.exe
