GRPC Java客户端和NodeJS服务器之间的ssl握手问题

Question

我正在使用 GRPC（Java 客户端）通过 SSL 连接到 NodeJS 服务器。我正在使用的 SSL 上下文复制如下。我尝试运行 ssldump（在 Mac El Capitan OS 上）来帮助调试。当我尝试连接并向服务器发送消息时，服务器上出现以下异常：

chttp2_server.c:123] Handshaking failed: {"created":"@1489433622.628015000","description":"Handshake read failed","file":"../src/core/lib/security/transport/security_handshaker.c","file_line":238,"referenced_errors":[{"created":"@1489433622.628009000","description":"Socket closed","fd":24,"file":"../src/core/lib/iomgr/tcp_posix.c","file_line":249,"target_address":"ipv6:[::1]:60820"}]}


        SslContext sslContext = GrpcSslContexts.forClient()
                .startTls(true)
                .sslProvider(defaultSslProvider())
                .trustManager(publicCert)
                .keyManager(clientCert, clientKey)
               // .ciphers(null)  //testing
                .build();

我只看到 ssldump 的以下输出：

780    1880.8428 (0.0405)  C>S  TCP FIN
780    1880.8433 (0.0005)  S>C  TCP FIN
New TCP connection #1020: localhost(61531) <-> localhost(96758)

---------------------------------------------------------------

New TCP connection #1021: localhost(61532) <-> localhost(90051)

对于如何进一步解决此问题的任何想法将不胜感激。

我删除了似乎导致问题的“usePlaintext(false)”语句。

channelBuilder = NettyChannelBuilder.forAddress(host, port)
                    .overrideAuthority("localhost")
                    .negotiationType(NegotiationType.TLS)
                    **//.usePlaintext(false)**
                    .sslContext(sslContext);
