Question

How do I access the uploaded file in Tornado, when using a put request?

@require_basic_auth
class UploadFile(tornado.web.RequestHandler):
    def put(self, params):
        path = calculate_path(params)
        # TODO: create an empty binary file at path and then copy 
        # the request input stream to it.

@require_basic_auth
class UploadFile(tornado.web.RequestHandler):
    def put(self, params):
        path = calculate_path(params)
        with open(path, 'wb') as out:
            body = self.request.get_argument('data')
            out.write(bytes(body, 'utf8'))        

…was what I needed.

Found on some ActiveState pages.
