Python Flask Uploading FIles

Question

I'm trying to upload user selected image into my firebase.

When I browse for the file

file = request.files['inputFile']

and I try this

storage.child("images/examples.jpg").put(file)

I get an error

io.UnsupportedOperation: fileno

How do I go about fixing this? I just want user to select the file and I be able to make use of the .jpg file and upload it

The put method takes a path to a local file (and an optional user token).

request.files[key] returns a custom object that represents the uploaded file. Flask documentation links: file uploads quickstart , incoming request data api , FileStorage class .

You need to store the uploaded file data to a local file, and the pass that file name to the put method:

request.files['inputFile'].save("some_filename.ext")
storage.child("images/examples.jpg").put("some_filename.ext")

Look into the tempfile module to generate random temporary file names (instead of using the hard coded some_filename.ext , which obviously is not a very good idea with concurrent requests).
