我在 Golang 中有一个gRPC 服务器,它使用以下 ServerOptions 启用了 mTLS:
// getServerOptions returns a list of GRPC server options.
// Current options are TLS certs and opencensus stats handler.
func (h *serviceHandler) getServerOptions() []grpc.ServerOption {
tlsCer, err := tls.LoadX509KeyPair(tlsDir+"tls.crt", tlsDir+"tls.key")
if err != nil {
logger.WithError(err).Fatal("failed to generate credentials")
}
cfg := &tls.Config{
Certificates: []tls.Certificate{tlsCer},
ClientAuth: tls.RequireAndVerifyClientCert,
GetConfigForClient: func(*tls.ClientHelloInfo) (*tls.Config, error) {
h.certMutex.RLock()
defer h.certMutex.RUnlock()
return &tls.Config{
Certificates: []tls.Certificate{tlsCer},
ClientAuth: tls.RequireAndVerifyClientCert,
ClientCAs: h.caCertPool,
}, nil
},
}
// Add options for creds and OpenCensus stats handler to enable stats and tracing.
return []grpc.ServerOption{grpc.Creds(credentials.NewTLS(cfg)), grpc.StatsHandler(&ocgrpc.ServerHandler{})}
}
服务器对于 Golang 中的gRPC 客户端工作正常,但在证书交换握手后对于以下 gRPC c# 客户端失败。
static async Task Main(string[] args)
{
string baseAddress = "x.x.x.x";
var x509Cert = new X509Certificate2("client.pfx", "123");
var client = CreateClientWithCert("https://" + baseAddress + ":443", x509Cert);
try {
var response = await client.PostAllocateAsync(new AllocationRequest {Namespace = "Default"});
Console.Write(response.State.ToString());
}
catch(RpcException e)
{
Console.WriteLine($"gRPC error: {e.Status.Detail}");
}
catch
{
Console.WriteLine($"Unexpected error calling agones-allocator");
throw;
}
}
}
