[英]Can we utilize same websocket connection again?

原文 2014-05-09 15:00:59 0 1 java/ javascript/ websocket

Usecase: 用例：

I have connected to server via Websocket. 我已经通过Websocket连接到服务器。
Some how I got disconnected. 一些我如何断开连接。
Now server have something to deliver using same websocket. 现在服务器可以使用相同的websocket交付一些东西。
after few seconds I connected again.(My question raise here.) 几秒钟后，我再次连接。（我的问题在这里提出。）

When I(Client) connected again. 当我（客户端）再次连接时。 (Is there any way that I can reutilize same websocket connection I was connected earlier? ) Or Every time I have to reconnect using new websocket connection only? （有什么方法可以重用以前连接的相同的Websocket连接？）或每次我只需要使用新的Websocket连接重新连接时？

Answer to your question heavily relies on the implementations. 对您的问题的回答在很大程度上取决于实现。 From what I know, it is possible, but.. 据我所知，这是可能的，但是..

When WebSocket support is implemented on top of Servlet 3.1 API, it might not be possible, because I don't think that servlet implementation is able to reuse upgraded connection. 当在Servlet 3.1 API上实现WebSocket支持时，可能是不可能的，因为我认为Servlet实现无法重用升级后的连接。 Additionally, it also depends on the way how the connection was closed - closing the underlying TCP connection is valid close from WebSocket RFC point of view and then you don't have anything to reuse. 此外，这还取决于关闭连接的方式-从WebSocket RFC角度来看，关闭基础TCP连接是否有效是有效的，那么您就没有任何可重用的内容。

My qualified guess would be (if you are implementing client) - if the connection is left intact after close is detected, you might try to reuse it. 我的合格猜测是（如果正在实施客户端）-如果在检测到关闭后连接保持完整，则可以尝试重用它。 Otherwise you need to open the new one. 否则，您需要打开新的。
