Hi,
If I have other objects other than String, which is holding a jpg or png
file, I like to return it as Response body, how can I do?
I tried a piece of code like this:
mimetype = image/png
body = fs.open(access_path, 'rb')
return Response(body, content_type=mimetype)
Here "body" is an buffer object from a kind of filesystem which represents
the content in the file. Since, it doesn't support len() like String. I
can't passed the Response check for len(). I tried app_iter also like this:
return Response(app_iter=[body], content_type=mimetype)
But, if I did like this, the wsgiref will complain about the body is not
String type.

==========
Is there anyway to work around this?
Thanks a lot in advance!
