Tornado 是使用 Python 开发的全栈式(full-stack)Web 框架和异步网络库,最早由 Friendfeed 开发。通过使用非阻塞 IO,Tornado 可以处理数以万计的开放连接,是 long polling、WebSockets 和其他需要为用户维护长连接应用的理想选择。
Tornado 4.5.3 已发布,更新如下:
tornado.curl_httpclient
Improved debug logging on Python 3.
tornado.httpserver
Content-LengthandTransfer-Encodingheaders are no longer sent with 1xx or 204 responses (this was already true of 304 responses).Reading chunked requests no longer leaves the connection in a broken state.
tornado.iostream
Writing a memoryview can no longer result in "BufferError: Existing exports of data: object cannot be re-sized".
tornado.options
Duplicate option names are now detected properly whether they use hyphens or underscores.
tornado.testing
.AsyncHTTPTestCase.fetch now uses
127.0.0.1instead oflocalhost, improving compatibility with systems that have partially-working ipv6 stacks.
tornado.web
It is no longer allowed to send a body with 1xx or 204 responses.
tornado.websocket
Requests with invalid websocket headers now get a response with status code 400 instead of a closed connection.
