go grpc 枚举使用

有不明白的地方欢迎提问交流，共同进步
日积一小步，月累一大步。。。。。
1 .proto文件如下

syntax = "proto3";  // 协议为proto3

package api;  // 包名
option go_package = "/;api";
// 空消息
message Empty {};
// 简单返回结果
message ResultCode {
  int32 code = 1;
}

enum PushP{
  LowPush = 0;
  HighPush = 1;
}

message Push {
  PushP pushOption=1;
}

// 定义服务,可定义多个服务,每个服务可多个接口
service Data {
  //==============================================
  //向下位机设置低推，高推
  rpc SetPushPressure(Push)returns (ResultCode);
}
//protoc.exe --go_out=plugins=grpc:. api.proto

2 客户端文件如下

package main

import (
	"fmt"
	"golang.org/x/net/context"
	"google.golang.org/grpc"
	api "grpc-test/src/test"
	"log"
	"time"
)

type client struct {
	receive api.DataClient
}

var c client = client{}

func main() {

	// 建立连接到gRPC服务
	conn, err := grpc.Dial("127.0.0.1:9999", grpc.WithInsecure())
	if err != nil {
		log.Fatalf("did not connect: %v", err)
	}
	// 函数结束时关闭连接
	defer conn.Close()

	// 创建Waiter服务的客户端
	//t := test.NewWaiterClient(conn)

	c.receive = api.NewDataClient(conn)

	cycleTest()

}




func cycleTest(){
	timer := time.NewTicker(time.Millisecond * 100)
	for {
		select {
		case <-timer.C:
			//c.GetOrder()
			c.setPush()
		}
	}
}

//枚举通信
func(c *client)setPush(){

	var set *api.Push

	set = &api.Push{PushOption: api.PushP_LowPush}

	v, err := c.receive.SetPushPressure(context.Background(), set)
	if err != nil {
		log.Fatalf("请求服务失败: %v", err)
	}
	if v.Code == 1 {
		//value= &api.ResultCode{}
		fmt.Println("请求成功", v.Code)
	}
}

3.服务端程序

package api

import (
	"context"
	"errors"
	"fmt"
	"google.golang.org/grpc"

)



var simpleSuccessCode = &ResultCode{
	Code: 1,
}
var failCode = &ResultCode{
	Code: 2,
}

func (h *dataServer) SetPushPressure(ctx context.Context, value *Push) (*ResultCode, error) {
	ctl := service.GetValveControlInstance().Rock.Handle
	v := value.GetPushOption()
	r := value.GetDrillRotate()
	switch v.Number() {
	case 0:
		ctl.LowPush = true
		ctl.HighPush = false
	case 1:
		ctl.HighPush = true
	ctl.LowPush = false
	default:
	ctl.LowPush = true
	}
	ctl.PushState=int(v.Number())
	
	c := v.Number()
	fmt.Println(c)
	return simpleSuccessCode, nil
}
func StartApiService() {
	lis, err := net.Listen("tcp", "0.0.0.0:9999")
	if err != nil {
		panic(err)
	}
	s := grpc.NewServer()
	RegisterDataServer(s, &dataServer{mu: &sync.Mutex{}})
	err = s.Serve(lis)
	if err != nil {
		panic(err)
	}
}
