Question

I have faced this problem several times that whenever we serve files from Blobstore API.
It is always downloaded as :

serve.fileNameExtention

is there any possible way that we can serve or download the file with the name we saved it.

i.e. someName.docx

If it is possible please tell me how to do it, because I have searched over internet but I couldn’t found out any solution for it.

Answer 1

Set it in header:

public void doGet(HttpServletRequest req, HttpServletResponse res)
    throws IOException {
        BlobKey blobKey = new BlobKey(req.getParameter("blob-key")); //example
        String filename = "someName.docx";
        res.setHeader("Content-Disposition", "attachment; filename=\"" +fileName +\"");

        blobstoreService.serve(blobKey, res);
    }
