GRPC - grpcurl: interact with gRPC servers

https://github.com/fullstorydev/grpcurl

Install:

go install github.com/fullstorydev/grpcurl/cmd/grpcurl@latest

Add code to enable server reflection:

import "google.golang.org/grpc/reflection"

reflection.Register(s)  // s is a grpc server

In Makefile:

srvaddr=0.0.0.0:50051
gcurl:
	grpcurl -cacert ./certs/ca_cert.pem \
	        -authority "check.test.example.com" \
	        -reflect-header 'auth_token: authd' \
	        $(srvaddr) $(command)

Run grpcurl with Makefile:

zzh@ZZHPC:/zdata/Github/zgrpc-go-professionals$ make command=list gcurl
grpcurl -cacert ./certs/ca_cert.pem \
        -authority "check.test.example.com" \
        -reflect-header 'auth_token: authd' \
        0.0.0.0:50051 list
grpc.reflection.v1.ServerReflection
grpc.reflection.v1alpha.ServerReflection
todo.v2.TodoService

zzh@ZZHPC:/zdata/Github/zgrpc-go-professionals$ make command="describe todo.v2.TodoService" gcurl
grpcurl -cacert ./certs/ca_cert.pem \
        -authority "check.test.example.com" \
        -reflect-header 'auth_token: authd' \
        0.0.0.0:50051 describe todo.v2.TodoService
todo.v2.TodoService is a service:
service TodoService {
  rpc AddTask ( .todo.v2.AddTaskRequest ) returns ( .todo.v2.AddTaskResponse );
  rpc DeleteTasks ( stream .todo.v2.DeleteTasksRequest ) returns ( stream .todo.v2.DeleteTasksResponse );
  rpc ListTasks ( .todo.v2.ListTasksRequest ) returns ( stream .todo.v2.ListTasksResponse );
  rpc UpdateTasks ( stream .todo.v2.UpdateTasksRequest ) returns ( .todo.v2.UpdateTasksResponse );
}
