Hi Yufeng,
My server side code exactly like yours.
My certificates and keys are fine, because when I plug them into example
route_guide code (grpc-go/examples/route_guide) they work.
My server-client logic is also fine without certificates. The moment I
enable certificates, I get this error:
rpc error: code = Unavailable desc = all SubConns are in TransientFailure
My Server side code:
lis, err := net.Listen("tcp", port)
if err != nil {
return fmt.Errorf("Failed to listen: %s", err)
}
creds, err := credentials.NewServerTLSFromFile(certFile, keyFile)
if err != nil {
return fmt.Errorf("could not load keys: %s", err)
}
opts := []grpc.ServerOption{grpc.Creds(creds)}
grpcServer := grpc.NewServer(opts...)
pb.RegisterHelloServer(grpcServer, newServer())
if err := grpcServer.Serve(lis); err != nil {
return fmt.Errorf("Failed to start Hello Server: %s", err)
}
My Client side code:
================
creds, err := credentials.NewClientTLSFromFile(certFile, "")
if err != nil {
log.Fatalf("could not load cert: %s", err)
}
conn, err = grpc.Dial(port, grpc.WithTransportCredentials(creds))
if err != nil {
log.Fatalf("Failed to connect to server: %s", err)
return
}
defer conn.Close()
c := pb.NewHelloClient(conn)
r, err := c.HelloServer(context.Background(), &pb.Request{Name: "Myname"
, Id:10})
