Ping Service

This directory has an implementation of a grpc test service.

The service implements the following function:

func Ping(request *PingRequest) (*PingResponse, error)

The PingRequest structure is defined as follows:

type PingRequest struct {
        Error   int32  
	Message string
        Headers map[string]string
}

If the Error in the request is OK(0) the function returns a PingResponse with the same Message than the request. Otherwise, the function generates and error with the status defined in Error and the message defined in Message. The server will return the Headers defined in the request as part of the response's header metadata.

Build

If you modify the protobuf definition you must re-generate the grpc code.

Install the required toolchain:

go install google.golang.org/protobuf/cmd/protoc-gen-go
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc

From the root of this project, execute the following command

protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative pkg/testutils/grpc/ping/ping.proto
