I am using signed URLs to upload/download files to/from GCS.
Uploading files went fine, however when i try to download the file I can see a meta data header and footer are appended to the file, as in the attached screen shot. The same happens to image files, which makes the image non-viewable.
Is there a way to ensure the file added to GCS does not get modified in anyway ?
The data appended to your upload is boundary markers. That means you are using the HTTP POST method with Content-Type: multipart/form-data.
Data is sent as a block of data ("body part"), with a user agent-defined delimiter ("boundary") separating each part. The keys are given in the Content-Disposition header of each part.
To upload data using a Signed URL, use the HTTP PUT method or switch to Signed Policy Documents.
