Netty代理示例中ctx.write（Unpooled.EMPTY

Netty代理示例中ctx.write（Unpooled.EMPTY_BUFFER）的用途是什么(What's the purpose of ctx.write(Unpooled.EMPTY_BUFFER) in Netty proxy example)

在Netty 代理示例的 HexDumpProxyBackendHandler中， channelActive方法的代码如下：

public void channelActive(ChannelHandlerContext ctx) { ctx.read(); ctx.write(Unpooled.EMPTY_BUFFER); }

我的问题是ctx.write(Unpooled.EMPTY_BUFFER)的目的是什么？ 在通道激活后是否需要发送空的TCP消息帧？

In HexDumpProxyBackendHandler of Netty proxy example , the code of the method channelActive likes following:

public void channelActive(ChannelHandlerContext ctx) { ctx.read(); ctx.write(Unpooled.EMPTY_BUFFER); }

My question is what's the purpose of ctx.write(Unpooled.EMPTY_BUFFER)? Is it necessary to send an empty TCP message frame after the channel active?

没有理由，这很可能是错过了被删除。 我将清理示例以将其删除。 谢谢你让我们知道

There is not reason and this was most likely missed to be removed. I will clean up the example to remove it. Thanks for let us know
