Question

我有一个启用了SSL的gRPC服务器（使用JDK作为ALPN提供程序）。在客户端，我创建了一个通道并指定了我的信任库以包含服务器的公钥证书。这是我的操作方式（根据官方参考）：

Channel channel = NettyChannelBuilder.forAddress("localhost", 8080)
        .sslContext(GrpcSslContexts.forClient().trustManager(new File("conf/server.crt")).build()).build();

在JVM中启用ssl调试后，我得到以下提示：

grpc-default-worker-ELG-3-2, called closeOutbound()
grpc-default-worker-ELG-3-2, closeOutboundInternal()
grpc-default-worker-ELG-3-2, called closeInbound()
grpc-default-worker-ELG-3-2, fatal error: 80: Inbound closed before receiving peer's close_notify: possible truncation attack?
javax.net.ssl.SSLException: Inbound closed before receiving peer's close_notify: possible truncation attack?
grpc-default-worker-ELG-3-2, SEND TLSv1.2 ALERT:  fatal, description = internal_error
grpc-default-worker-ELG-3-2, Exception sending alert: java.io.IOException: writer side was already closed.
grpc-default-worker-ELG-3-2, called closeOutbound()
grpc-default-worker-ELG-3-2, closeOutboundInternal()
grpc-default-worker-ELG-3-2, called closeOutbound()
grpc-default-worker-ELG-3-2, closeOutboundInternal()

我得到的例外情况：

Exception in thread "main" io.grpc.StatusRuntimeException: UNKNOWN
    at io.grpc.stub.ClientCalls.toStatusRuntimeException(ClientCalls.java:210)
    at io.grpc.stub.ClientCalls.getUnchecked(ClientCalls.java:191)

    at client.MyClient.main(MyClient.java:21)
Caused by: java.nio.channels.ClosedChannelException
    at io.netty.handler.ssl.SslHandler.channelInactive(...)(Unknown Source)

Java gRPC：客户端无法连接到启用SSL的服务器
