java - Grpc Java 客户端的 SSL 连接

Question

我正在尝试通过 GRPC-SSL 将 Java 客户端连接到非 Java 服务器。我可以在不使用 SSL 时连接到服务器。当我尝试使用 SSL 上下文(使用提供的 pem 文件)创建 ManagedChannel 时，出现以下异常(相同的 pem 文件适用于 NodeJS 客户端)。

ManagedChannel channel = NettyChannelBuilder.forAddress("localhost", 10010)
    .sslContext(GrpcSslContexts.forClient().trustManager(new File("./test/myprivkey.pem")).build())
    .build();

trustManager 调用异常:

build.gradle相关部分

compile 'io.netty:netty-tcnative-boringssl-static:1.1.33.Fork26'

任何想法可能导致问题或如何进一步解决此问题？

Answer 1

我读错了文件作为构建 SslContext 的证书文件。用正确的证书文件替换不正确的输入解决了这个问题。
