Second , Be sure that should response header first , then send your binary data to client use 'wsgi.file_wrapper':

if 'wsgi.file_wrapper' in environ:
    return environ['wsgi.file_wrapper'](filelike, block_size)
else:
    return iter(lambda: filelike.read(block_size), '')

　　

 

At last , Take a look at Stackoverflow:  Returning a file to a WSGI GET request
