注册服务到etcd中

如上存放一些服务的key到etcd中，商品有两个，主要是为了负载均衡的key

func NewService() *Service {
    config := clientv3.Config{
        Endpoints:   []string{"106.12.72.181:23791", "106.12.72.181:23792"},
        DialTimeout: 10 * time.Second,
    }
    client, _ := clientv3.New(config)
    return &Service{client: client}
}

func (this *Service) RegService(id string, name string, address string) error {
    fmt.Println(22)
    kv := clientv3.NewKV(this.client)
    key_prefix := "/services/"
    _, err := kv.Put(context.Background(), key_prefix+id+"/"+name, address)
    fmt.Println(err)
    return err
}
