Send file through Django Rest

I need to download image object from vary object storage buckets, and send that to a user through Django Rest Framework.

I have something like that:

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 variable contains bytes type.

While testing I'm receiving error: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte

What can be solution for this problem?

If you're looking to pass the image straight through Django Rest Framework to the user, it may be more appropriate to use an HttpResponse.

from django.http import HttpResponse

return HttpResponse(data, content_type="image/png")

Django Rest Framework's own Response will try and render the binary data which may cause the encoding issue you're seeing.

You need to import base64 and need to convert byte data into base64 encoded format, to resolve that issue.

import base64 
data = base64.b64encode(data)

==== OR =====

I respect @Will Keeling answer and would like to have that in my post as well. 

from django.http import HttpResponse

return HttpResponse(data, content_type="image/png")
