ProductInfo Service and Client - Go Implementation

Building and Running Service

In order to build, Go to Go module root directory location (grpc-gateway/go/server) and execute the following shell command,

In order to run, Go to Go module root directory location (grpc-gateway/go/server) and execute the following shell command,

./bin/server

Building and Running Client

In order to build, Go to Go module root directory location (grpc-gateway/go/client) and execute the following shell command,

go build -i -v -o bin/client

In order to run, Go to Go module root directory location (grpc-gateway/go/client) and execute the following shell command,

./bin/client

  • Add a new product to the ProductInfo service.
$ curl -X POST http://localhost:8081/v1/product -d '{"name": "Apple", "description": "iphone7", "price": 699}'

"38e13578-d91e-11e9-819f-6c96cfe0687d"
  • Get the existing product using ProductID
$ curl http://localhost:8081/v1/product/38e13578-d91e-11e9-819f-6c96cfe0687d

{"id":"38e13578-d91e-11e9-819f-6c96cfe0687d","name":"Apple","description":"iphone7","price":
