# Usage
- Install protoc
```
git clone https://github.com/protocolbuffers/protobuf
cd protobuf
git checkout v3.6.1.3
./autogen.sh
./configure
make -j8
make install
```
- Add tarsrpc plugin for protoc-gen-go
```
go get github.com/golang/protobuf/{proto,protoc-gen-go}
go get github.com/TarsCloud/TarsGo/tars
cd $GOPATH/src/github.com/golang/protobuf/protoc-gen-go && cp -r $GOPATH/src/github.com/TarsCloud/TarsGo/tars/tools/pb2tarsgo/protoc-gen-go/{link_tarsrpc.go, tarsrpc} .
go install
export PATH=$PATH:$GOPATH/bin
```
# example
- proto file
```golang
syntax = "proto3";
package helloworld;
// The greeting service definition.
service Greeter {
// Sends a greeting
rpc SayHello (HelloRequest) returns (HelloReply) {}
}
// The request message containing the user's name.
message HelloRequest {
string name = 1;
}
// The response message containing the greetings
message HelloReply {
string message = 1;
}
```
- generate the code
```
protoc --go_out=plugins=tarsrpc:. helloworld.proto
```
- server
```golang
package main
import (
"github.com/TarsCloud/TarsGo/tars"
"helloworld"
)
type GreeterImp struct {
}
func (imp *GreeterImp) SayHello(input helloworld.HelloRequest)(output helloworld.HelloReply, err error) {
output.Message = "hello" + input.GetName()
return output, nil
}
func main() { //Init servant
imp := new(GreeterImp) //New Imp
app := new(helloworld.Greeter) //New init the A JCE
cfg := tars.GetServerConfig() //Get Config File Object
app.AddServant(imp, cfg.App+"."+cfg.Server+".GreeterTestObj") //Register Servant
tars.Run()
}
```
- client
```golang
package main
import (
"fmt"
"github.com/TarsCloud/TarsGo/tars"
"helloworld"
)
func main() {
comm := tars.NewCommunicator()
obj := fmt.Sprintf("StressTest.HelloPbServer.GreeterTestObj@tcp -h 127.0.0.1 -p 10014 -t 60000")
app := new(helloworld.Greeter)
comm.StringToProxy(obj, app)
input := helloworld.HelloRequest{Name: "sandyskies"}
output, err := app.SayHello(input)
if err != nil {
fmt.Println("err: ", err)
}
fmt.Println("result is:", output.Message)
}
```
