I am trying to convert files to gzip files and then upload them to S3. When I check in S3, the files are there but they don't have a type specified. How can I specify the content type?
for i in testList:
with contextlib.ExitStack() as stack:
source_file = stack.enter_context(open(i , mode="rb"))
destination_file = io.BytesIO()
destination_file_gz = stack.enter_context(gzip.GzipFile(fileobj=destination_file, mode='wb'))
while True:
chunk = source_file.read(1024)
if not chunk:
break
destination_file_gz.write(chunk)
destination_file_gz.close()
destination_file.seek(0)
bucket.upload_fileobj(destination_file, fileName, ContentType='application/gzip')
If I add ContentType as an argument to the last line, I get an error:
"errorMessage": "bucket_upload_fileobj() got an unexpected keyword argument 'ContentType'",
CodePudding user response:
Use
bucket.upload_fileobj(destination_file, fileName,ExtraArgs={'ContentType': "application/gzip"})
