我正在编写一个用于 websocket 服务器负载测试的工具。我需要创建很多(数万个)到服务器的客户端连接。
所以我有一个客户端类。在这个类中,我创建了以下新版本:
- ChannelPipelineFactory(与我的处理程序和 webscoket 客户端握手)
- 客户端引导
在 run() 方法中,我有以下代码:
public void run() {
clientBootstrap.setPipelineFactory(clientChannelPipelineFactory);
ChannelFuture future = clientBootstrap.connect(
new InetSocketAddress(
clientConfiguration.getHost(),
clientConfiguration.getPort()
)
);
try {
future.awaitUninterruptibly().rethrowIfFailed();
WebSocketClientHandshaker handshaker = clientChannelPipelineFactory.getHandshaker();
channel = future.getChannel();
handshaker.handshake(channel).awaitUninterruptibly().rethrowIfFailed();
} catch (Exception e) {
log.error("Error in the client channel", e);
stop();
}
}
ChannelFuture 返回的通道保存为客户端中的字段。
然后我做我的工作并尝试关闭所有打开的频道。stop() 方法:
public void stop() {
log.debug(String.format("Close channel for client(%s)", id));
if (channel != null) {
if (channel.isWritable()) {
log.debug(String.format("Channel for client(%s) is writable", id));
ChannelFuture writeFuture = channel.write(new CloseWebSocketFrame());
writeFuture.addListener(ChannelFutureListener.CLOSE);
}
}
clientBootstrap.releaseExternalResources();
}
但是,当在任何客户端上调用 stop() 时,它会关闭所有通道!?
ps 关闭所有通道的代码(单线程):
for (FSBBridgeServerClient client : clients) {
for (FSBBridgeServerClient subClient : clients) {
log.debug("c:" + subClient.getChannel());
log.debug("c:" + subClient.getChannel().isOpen());
}
client.stop();
}
一些调试日志:
