# grpcox教程
grpc版本的postman使用教程
## grpcox介绍
[grpcox](https://github.com/gusaul/grpcox)是一个非常棒的工具,类似postman一样,可以帮助人们调试grpc接口. 当然目前还不能做到像postman一样,实现很多自动化的功能,但是作为界面友好的调试助手已经足够了.
## 使用教程
所有文件都位于[我的github](https://github.com/nkbai/-grpcox-example)
### proto文件
#### proto文件
```proto
syntax = "proto3";
package proto;
// 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;
}
```
#### Makefile
```Makefile
.PHONY: gogen
gogen:
protoc -I=. -I=$(GOPATH)/src --go_out=plugins=grpc:. ./*.proto
```
### grpcServer
按照grpcox文档中的说明,要求server必须支持reflection,对于go语言版本的grpc来说,支持的非常完善. 两行代码即可.
```go
package main
import (
"log"
"net"
pb "github.com/nkbai/grpcox-example/proto"
"golang.org/x/net/context"
"google.golang.org/grpc"
"google.golang.org/grpc/reflection"
)
const (
port = ":50051"
)
type Config struct {
IP string `json:"ip"`
Port string `json:"port"`
}
// server is used to implement helloworld.GreeterServer.
type server struct{}
// SayHello implements helloworld.GreeterServer
func (s *server) SayHello(ctx context.Context, in *pb.HelloRequest) (*pb.HelloReply, error) {
log.Println("get request")
return &pb.HelloReply{Message: "Hello " + in.Name}, nil
}
func main() {
lis, err := net.Listen("tcp", "0.0.0.0:50051")
if err != nil {
log.Fatalf("failed to listen: %v", err)
}
s := grpc.NewServer()
pb.RegisterGreeterServer(s, &server{})
// Register reflection service on gRPC server.
reflection.Register(s)
if err := s.Serve(lis); err != nil {
log.Fatalf("failed to serve: %v", err)
}
}
```
其中重要的是` "google.golang.org/grpc/reflection" `和`reflection.Register(s)`两行.其他与普通的grpc server没有区别.
### grpcox和greeter_server配合效果
```bash
cd $GOPATH/github.com/nkbai/grpcox-example/greeter_server
go run main.go &
cd $GOPATH/github.com/gusaul/grpcox
go run grpcox.go
```
然后打开浏览器:
