testing like this:

$ docker run --rm -it -p 50051:50051 -p 8082:8082 cad70904c875
2023/09/12 01:30:20 Server listening at [::]:50051

@chujieyang can you please review this one ?

@chujieyang can you please review this one ?

I agree with this.

[glimchb]

@chujieyang do you understand why I get this error?

$ curl -kL http://localhost:8082/v1
{"code":5,"message":"Not Found","details":[]}

is it due to wrong http annotation ?

        option (google.api.http) = {
            get: "/v1/{name=inventory/*/inventory/*}"
        };

here https://github.com/opiproject/opi-api/blob/3b18c0431f460b3e01707809d69b232465ccb917/common/v1/inventory.proto#L31

or wrong curl command ?

As the proto file define, you can use this command to test:
curl -kL http://localhost:8082/v1/inventory/1/inventory/2
