Return binary data by webob.Response

Question

I`m trying to return binary in webob.Response but error happens

file = open(filePath, 'rb')
buffer = file.read()
file.close()

self._response.body = buffer

Gives the traceback

"F:\Program Files\Python32\python.exe" G:/development/projects/AutoBlog/main.py
Traceback (most recent call last):

    print(wsgiApplication)

    return body.decode(self.charset, self.unicode_errors)

Looks like webob is treating your body as a string, whereas it is actually a binary object. Maybe you need to set the content type?
