How to download a file with its original name from the GAE blobstore?

Once you upload the file to blobstore, it renames it as "s9QmBqJPuiVzWbySYvHVRg ==". If you go to your "/ serve" URL to download the file, the downloaded file is called this mess of letters.

Is there a way for the downloaded file to keep the original file name at boot time?

When a file is uploaded using BlobUploadHandler original file name is saved as a name property in the newly created BlobInfo entity.

In the blob service handler, you can specify that the blob should be returned as a downloadable attachment, and you can specify which name to save it with

 from google.appengine.ext import webapp import urllib class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler): def get(self, blob_info_key=None): blob_info_key = str(urllib.unquote(blob_info_key)) blob_info = retrieve_blob_info(blob_info_key) self.send_blob(blob_info, save_as=blob_info.filename) blob_app = webapp.WSGIApplication([ ('/_s/blob/([^/]+)', blob.ServeHandler), ], debug=config.DEBUG)

In the GAE console , the BLOB viewer, when you are viewing a single BLOB, in the lower right part as shown in the screenshot below.

The code you reference is the key of the BlobInfo object, but the original file name is saved as a property.

If you need an easy way to download a file by its name, you can use this code, which I use for my ServeHandler, it works for my needs, downloads a file by its name instead of the blobstore key:

 class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler): def get(self, resource): blobs = blobstore.BlobInfo.gql("WHERE filename = '%s'" %(urllib.unquote(resource))) if blobs.count(1) > 0: blob_info = blobstore.BlobInfo.get(blobs[0].key()) self.send_blob(blob_info,save_as=True)
