我与测试应用程序的连接保持在同一位置终止，没有任何错误。
我认为可能有什么东西触发了通道/连接关闭，但我不知道它可能是什么。如果我更改代码中的打印输出，它关闭的确切位置会略有变化，所以时间似乎在不同的线程上。
我已经为此工作了四天，并将自己列为正式卡住的人。
这是我的连接代码：
final HttpQueryRequestImpl realRequest = (HttpQueryRequestImpl) getPredecessorQueryResolver().resolvePredecessorResults(getPredecessorResults(), getQueryRequest(), getId());
// Configure the client.
// TODO determine if this ClientBootstrap object can be reused. Indications in the doucmentation
// seem to say yes, with caveats. Reusing the pool would improve performance. Caveats must be investigated.
final ClientBootstrap bootstrap = new ClientBootstrap(
new NioClientSocketChannelFactory(
Executors.newCachedThreadPool(),
Executors.newCachedThreadPool()));
// Set up the event pipeline factory.
bootstrap.setPipelineFactory(new HttpSnoopClientPipelineFactory());
// TODO audit and timestamp logging
if (logger.isInfoEnabled()) {
logger.info("Starting connection to !" + realRequest.getUri());
}
// Start the connection attempt.
// ChannelFuture future = bootstrap.connect(new InetSocketAddress(realRequest.getHost(), realRequest.getPort()));
logger.info(realRequest.getHost() + " " + realRequest.getPort());
ChannelFuture future = bootstrap.connect(new InetSocketAddress("myname.organization.com", 8443));
// register some things to happen after the channel completes
future.addListener(new ChannelFutureListener() {
@Override
public void operationComplete(ChannelFuture future) throws Exception {
if (!future.isSuccess()) {
logger.error("Error connecting to " + realRequest.getHost() + ":" + realRequest.getPort() + " " + realRequest.getUri());
bootstrap.releaseExternalResources();
} else {
if (logger.isInfoEnabled()) {
logger.info("Connected to " + realRequest.getHost() + ":" + realRequest.getPort() + " " + realRequest.getUri());
}
// Send the HTTP request.
Channel channel = future.getChannel();
HttpRequest request = new DefaultHttpRequest(
HttpVersion.HTTP_1_1, HttpMethod.GET, "/factorial");
request.setHeader(HttpHeaders.Names.HOST, "myname.organization.com");
request.setHeader(HttpHeaders.Names.CONNECTION, HttpHeaders.Values.CLOSE);
request.setHeader(HttpHeaders.Names.ACCEPT_ENCODING, HttpHeaders.Values.GZIP);
ChannelFuture writeFuture = channel.write(request);
writeFuture.addListener(new ChannelFutureListener() {
@Override
public void operationComplete(ChannelFuture future) throws Exception {
logger.info("Wrote data complete");
// TODO once bootstrap is reused, get rid of this
// Shut down executor threads to exit.
// bootstrap.releaseExternalResources();
}
});
}
}
});
这就是启用SSL调试后我的输出：
32 [main] INFO nettyliteserver.remotequeries.HttpsQuery - Starting connection to !https://myname.organization.com:8443/factorial

Using SSLEngineImpl.
985 [main] INFO nettyliteserver.ssl.FlexibleErrorSslHandler - handleDownstream
这就是它的终点。我对打印输出做了一些更改，所以有时我也会从logger.info（"Connected to"+realRequest.getHost（）+"："+realRequest.getPort（）+"+realRequest.getUri（））获得一行打印输出；但我真的不知道是什么原因导致它关闭了。
我尝试重写netty SSLHandler，并在它的所有公共操作上添加了一个打印输出，但close（）、channelConnected（）、channelDisconnected（）等方法从未被调用。握手（）也是如此。
我的管道设置为进行握手：
public class HttpSnoopClientPipelineFactory implements ChannelPipelineFactory {
public ChannelPipeline getPipeline() throws Exception {
// Create a default pipeline implementation.
ChannelPipeline pipeline = pipeline();
// Enable HTTPS
SSLEngine engine =
SecureChatSslContextFactory.getClientContext().createSSLEngine();
engine.setUseClientMode(true);
System.out.println("HERE!!!!!!!!!!!!");
pipeline.addLast("ssl", new SslHandler(engine));
pipeline.addLast("codec", new HttpClientCodec());
// Remove the following line if you don't want automatic content decompression.
pipeline.addLast("inflater", new HttpContentDecompressor());
// Uncomment the following line if you don't want to handle HttpChunks.
//pipeline.addLast("aggregator", new HttpChunkAggregator(1048576));
pipeline.addLast("handler", new HttpSnoopClientHandler());
return pipeline;
}
}
我的自定义SSLHandler实际上与库的SSLHandler相同，我只是在委托给超级版本之前重写了添加打印输出的方法。
它看起来唯一被调用的是handleDownstream（）
连接成功后，您需要自己调用SslHandler.handshake（）。
类似于：
future.getChannel().getPipeline(SslHandler.class).handshake();
这需要在连接方法或添加到ChannelPipeline 的SimpleChannelUpstreamHandler实现返回的ChannelFuture中完成
Netty文档状态：
握手
如果isIssueHandshake（）为false（默认值），则需要注意自己调用handshake（）。在大多数情况下，SslHandler是在"客户端模式"中使用，您希望在已建立连接。如果setIssueHandshake（布尔值）设置为是的，你不需要担心这一点，因为SslHandler会小心。
请参阅javadoc
因此，在建立连接之前，您应该在SslHandler上设置isIssueHandshake：
SslHandler sslHandler = new SslHandler(engine);
setIssueHandshake(boolean);
pipeline.addLast("ssl", sslHandler);
