使用2向SSL握手设置Netty（客户端和服务器证书）

我现在正在尝试使用两种方式的SSL握手来设置Netty，其中客户端和服务器都在其中并验证证书。

这似乎没有在SslHandler中实现。有没有人这样做？我想它将在SslHandler.handshake操作中运行并委托给javax.net.ssl.SSLEngine？

任何提示/技巧/预先存在的实现？

谢谢！

回答（stackoverflow不允许我以正常方式发布它）我发现，如果在设置SslHandler之前在SSLEngine对象上设置了needClientAuth标志，就可以解决此问题！

回答：

这是基于netty项目的HttpSnoop服务器示例的解决方案。

设置客户端管道时，必须如下设置ssl引擎：

public ChannelPipeline getPipeline() throws Exception {
    // Create a default pipeline implementation.
    ChannelPipeline pipeline = pipeline();
    // Uncomment the following line if you want HTTPS
    SSLEngine engine = SecureChatSslContextFactory.getServerContext().createSSLEngine();
    engine.setUseClientMode(false);
    engine.setNeedClientAuth(true);
    pipeline.addLast("ssl", new SslHandler(engine));
    pipeline.addLast("decoder", new HttpRequestDecoder());
    pipeline.addLast("logger", new RequestAuditLogger());
    // Uncomment the following line if you don't want to handle HttpChunks.
    pipeline.addLast("aggregator", new HttpChunkAggregator(1048576));
    pipeline.addLast("outputLogger", new ResponseAuditLogger());
    pipeline.addLast("encoder", new HttpResponseEncoder());
    // Remove the following line if you don't want automatic content compression.
    pipeline.addLast("deflater", new HttpContentCompressor());
    pipeline.addLast("handler", new HttpSnoopServerHandler());
    return pipeline;
}
}

然后，必须对SSLContext进行如下修改，以建立除密钥库（SecureChatSslContextFactory）之外的信任库：

public final class SecureChatSslContextFactory {
private static Logger logger = LoggerFactory.getLogger(SecureChatSslContextFactory.class);
private static final String PROTOCOL = "TLS";
private static final SSLContext SERVER_CONTEXT;
private static final SSLContext CLIENT_CONTEXT;
static {
    SSLContext serverContext = null;
    SSLContext clientContext = null;
        // get keystore and trustore locations and passwords
    String keyStoreLocation = System.getProperty("javax.net.ssl.keyStore");
    String keyStorePassword = System.getProperty("javax.net.ssl.keyStorePassword");
    String trustStoreLocation = System.getProperty("javax.net.ssl.trustStore");
    String trustStorePassword = System.getProperty("javax.net.ssl.trustStorePassword");
    try {
        KeyStore ks = KeyStore.getInstance("JKS");
        ks.load(KeyStoreStreamManager.asInputStream(keyStoreLocation),
                keyStorePassword.toCharArray());
        // Set up key manager factory to use our key store
        KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        kmf.init(ks, keyStorePassword.toCharArray());
          // truststore
        KeyStore ts = KeyStore.getInstance("JKS");
        ts.load(KeyStoreStreamManager.asInputStream(trustStoreLocation),
                trustStorePassword.toCharArray());
        // set up trust manager factory to use our trust store
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ts);
        // Initialize the SSLContext to work with our key managers.
        serverContext = SSLContext.getInstance(PROTOCOL);
        serverContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
    } catch (Exception e) {
        throw new Error(
                "Failed to initialize the server-side SSLContext", e);
    }
    try {
        clientContext = SSLContext.getInstance(PROTOCOL);
        clientContext.init(null, SecureChatTrustManagerFactory.getTrustManagers(), null);
    } catch (Exception e) {
        throw new Error(
                "Failed to initialize the client-side SSLContext", e);
    }
    SERVER_CONTEXT = serverContext;
    CLIENT_CONTEXT = clientContext;
}
public static SSLContext getServerContext() {
    return SERVER_CONTEXT;
}
public static SSLContext getClientContext() {
    return CLIENT_CONTEXT;
}
private SecureChatSslContextFactory() {
    // Unused
}
}
