python - tornado server serve a file -


i know how serve static files / pngs etc far kept under web static path.

how go serving file @ path, /usr/local/data/table.csv ?

also, wondering if display page wise results(pagination) more concerned serving arbitrary location files + stay if remove them local (i mean once uploaded / cached). [that separate ques though]

on basic level, need read file , write response:

import os.path mimetypes import guess_type  import tornado.web import tornado.httpserver  basedir_name = os.path.dirname(__file__) basedir_path = os.path.abspath(basedir_name)  files_root = os.path.join(basedir_path, 'files')   class filehandler(tornado.web.requesthandler):      def get(self, path):         file_location = os.path.join(files_root, path)         if not os.path.isfile(file_location):             raise tornado.web.httperror(status_code=404)         content_type, _ = guess_type(file_location)         self.add_header('content-type', content_type)         open(file_location) source_file:             self.write(source_file.read())  app = tornado.web.application([     tornado.web.url(r"/(.+)", filehandler), ])  http_server = tornado.httpserver.httpserver(app) http_server.listen(8080, address='localhost') tornado.ioloop.ioloop.instance().start()

(disclaimer. quick writeup, won't work in cases, careful.)
