Question

我与测试应用程序的连接始终在同一个地方终止，没有任何错误。

我想也许某事正在触发关闭频道/连接，但我不知道它可能是什么。如果我在代码中更改打印输出，它关闭的确切位置会稍微改变，因此时间似乎在不同的线程上。

我已经为此工作了四天，并将自己列为官方卡住。

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();
                    }
                });

            }
        }
    });

这是我的输出在启用SSL调试时的样子：

Using SSLEngineImpl.

985 [main] INFO nettyliteserver.ssl.FlexibleErrorSslHandler - handleDownstream

这就是终止的地方。我已经改变了一点打印输出，所以有时候我还得到一行，来自logger.info的打印输出（“连接到”+ realRequest.getHost（）+“：”+ realRequest.getPort（）+“”+ realRequest.getUri（））;但我真的不知道是什么导致它关闭。

我尝试覆盖netty SSLHandler并在其所有公共操作上添加了打印输出，但是从不调用close（），channelConnected（），channelDisconnected（）等方法。握手（）也不是。

我的管道设置为握手：

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与库的SslHandler非常相似，我只是在委托超级版本之前覆盖了添加打印输出的方法。

看起来唯一被调用的是handleDownstream（）

Answer 1

连接成功后，您需要自己调用SslHandler.handshake（）。

类似的东西：

future.getChannel().getPipeline(SslHandler.class).handshake();

这需要在您添加到ChannelPipeline的connect方法或SimpleChannelUpstreamHandler实现返回的ChannelFuture中完成

Answer 2

Netty文档声明：

<强>握手

如果isIssueHandshake（）为false（默认值），则需要注意   你自己调用handshake（）。在大多数情况下，SslHandler是   在“客户端模式”中使用，您希望一旦发出握手   建立了联系。如果setIssueHandshake（boolean）设置为   确实，你不需要像SslHandler那样担心这个问题   关心它。

请参阅javadoc

因此，您应该在建立连接之前在SslHandler上设置isIssueHandshake：

SslHandler sslHandler = new SslHandler(engine);
setIssueHandshake(boolean);
pipeline.addLast("ssl", sslHandler);

Netty ClientBootstrap SSL握手终止 - Channel / ClientBootstrap关闭？
