Issue with files downloaded or uploaded to S3 #12

Closed soumya-github closed 7 years ago

soumya-github commented 7 years ago

If files are downloaded using the GET method of the flow the files are getting corrupted. I tried with the below code also as said in the release. But it is not working. can you help. msg.payload=Buffer.from(msg.payload.Body).toString("utf-8")

ghost commented 7 years ago

I see that it is expected behaviour, as the documentation for put says "stringifies msg.payload and stores it in s3://buckey/key". So sorry for the comment but I'm asking myself how to write binary files.

I can't think of good a solution off the top of my head for this sorry.

One thing that might make it easier to use the uploaded file might be to base64encode the data prior to uploading, this will at least upload it in a standard encoding.
