I wrote the below code

    def decorator(f):
        @functools.wraps(f)
        def decorated_function(req):
            if (req.content_type != content_type):
                if (not req.content_type):
                    req.content_type = 'None'
                raise webob.exc.HTTPUnsupportedMediaType((_('The    media    type    %(bad_type)s    is    not    supported,    use    %(good_type)s') % {'bad_type': req.content_type, 'good_type': content_type}), json_formatter=json_error_formatter)
            else:
                return f(req)
        return decorated_function
    return decorator
