什么时候使用keepalive调用channelInactive？ [英] When is channelInactive called with keepalive on?

问题描述

我有一个处理一些http请求的SimpleChannelInboundHandler：

I have a SimpleChannelInboundHandler which handles a few http requests:

CacheServerHandler extends SimpleChannelInboundHandler<FullHttpRequest>

当我没有明确关闭频道/连接并且keepalive为true时，每次都会调用channelInactive在channelRead0完成后？

When i do not explicitly close the channel/connection and keepalive is true, will channelInactive be called every time after channelRead0 is done?

或者当频道/连接关闭时，只会调用一次channelInactive吗？

Or will channelInactive only be called once when the channel/connection is closed?

我问这个是因为当http连接上的keepalive为true时，客户端不会关闭连接，客户端可以在不打开/关闭连接的情况下发送多个请求。

I ask this because when keepalive is true on a http connection the connection isn't closed by client and client can send multiple requests without opening/closing the connection.

推荐答案

只有在关闭频道时才会调用ChannelInactive（）。这是合同。

ChannelInactive() will only be called when the channel is closed. This is the contract.
