Golang
package main
import (
"fmt"
"log"
"golang.org/x/net/context"

pb "github.com/moul/pb/grpcbin/go-grpc"
)
func main() {

defer conn.Close()
// create client and context
client := pb.NewGRPCBinClient(conn)

// call DummyUnary

}Example with grpcc:
# fetch proto and install tool
$ wget -qN https://github.com/moul/pb/raw/master/grpcbin/grpcbin.proto
$ npm install -g grpcc
# interactive client
$ grpcc -i -p ./grpcbin.proto --address grpcb.in:9000
Connecting to grpcbin.GRPCBin on grpcb.in:9000. Available globals:
client - the client connection to GRPCBin
index (EmptyMessage, callback) returns IndexReply
dummyUnary (DummyMessage, callback) returns DummyMessage
dummyServerStream (DummyMessage, callback) returns DummyMessage
dummyClientStream (DummyMessage, callback) returns DummyMessage
dummyBidirectionalStreamStream (DummyMessage, callback) returns DummyMessage
printReply - function to easily print a unary call reply (alias: pr)
streamReply - function to easily print stream call replies (alias: sr)
createMetadata - convert JS objects into grpc metadata instances (alias: cm)
