有一个tornado的脚本,当客户端请求时服务器会向某处发出一个长耗时的http请求,但是当客户端停止请求时服务端的那一个请求也就毫无意义。
如何知晓客户端的连接情况?

Pelanggan menamatkan sambungan secara unilateral sama ada dengan menghantar mesej penamat kepada pelayan atau dengan menunggu pelayan tamat masa. Jika tidak, jika anda menamatkannya secara unilateral, pelayan tidak akan dapat menunggu dan membazir sumber. .

RequestHandler.on_connection_close()
Called in async handlers if the client closed the connection.
Override this to clean up resources associated with long-lived connections. Note that this method is called only if the connection was closed during asynchronous processing; if you need to do cleanup after every request override on_finish instead.
Proxies may keep a connection open for a time (perhaps indefinitely) after the client has gone away, so this method may not be called promptly after the end user closes their connection.
