Send file via Django Rest

Question

I need to load an image object from different object storage codes and send it to the user through the Django Rest Framework.

I have something like this:

if request.method == 'GET':

    # Get object using swiftclient
    conn = swiftclient.client.Connection(**credentials)
    container, file = 'container_name', 'object_name'
    _, data = conn.get_object(container, file)

    # Send object to the browser
    return Response(data, content_type="image/png")

data the variable contains the type of bytes.

During testing, I get an error message: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte

What could be the solution to this problem?

Answer 1

You need to import base64 and you need to convert the data to base64 encoded byte format to solve this problem.

import base64 
data = base64.b64encode(data)
