Is grpc case sensitive? about cp-web

[mastersingh24]

@rtang03 - the NodeJS grpc library does indeed use camelCase for the service methods. Are you seeing an issue?

[rtang03]

In my experimental program, I am using nodes grpc to calling my local dev sandbox. The grpc library returns error code: 12.

{"code":12,"metadata":{"_internal_repr":{}}}

I guess this is referred as "unimplemented method" Indeed, I could find the status code table. And therefore, I doubt that camelCase-ed client side (readCaCertificate) can call correctly original "ReadCACertifcate".

hmm - this code has been working for a while so not sure what's going on.
we'll give it another test on our end.

I guess that the CA server is implemented with grpc with go, and compiled to ca.pb.go. And, the give below interface.

// Client API for ECAP service
type ECAPClient interface {
    ReadCACertificate(ctx context.Context, in *Empty, opts ...grpc.CallOption) (*Cert, error)

and
func (c *eCAPClient) ReadCACertificate(ctx context.Context, in *Empty, opts ...grpc.CallOption) (*Cert, error) {

It is styled with upper-case-ed first letter.

Hence, the grpc.load in Nodejs and in GoLang, give different service.methods.

Maybe, I may try your working code. But, how can I trigger ECAP.readCaCertificate() in your code?

@rtang03 - sorry for the late response. I just cloned and reinstalled cp-web myself. Assuming you are in the cp-web folder and running membersrvc locally with the default config, if you run

node utils/loopback-connector-obcca/test/unit/02-test-connector.js

you will see all of the calls working

[rtang03]

Is the connection 127.0.0.1:30303 correct?

[mastersingh24]

Ah - the default port for membersrvc is 50051

This is not related to camelCase, nor grpc issue.

I git-pull latest fabric, and it works. My previous local dev is outdated, and did not give right behaviour. And, your code works as well.

Thank you for your help.
