GO操作etcd-526互联

PUT和SET
package main

import (
   "fmt"
   "go.etcd.io/etcd/Godeps/_workspace/src/golang.org/x/net/context"
   "go.etcd.io/etcd/clientv3"
   "time"
)

func main() {
   cli, err := clientv3.New(clientv3.Config{
      Endpoints:   []string{"127.0.0.1:2379"},
      DialTimeout: time.Second * 5,
   })
   if err != nil {
      fmt.Printf("connect to faild,err:%v", err)
      return
   }
   defer cli.Close()

   ctx, cancel := context.WithTimeout(context.Background(), time.Second)
   _, err = cli.Put(ctx, "zl", "最牛")
   if err != nil {
      fmt.Printf("put key faild,err:%v", err)
      return
   }
   cancel()

   ctx, cancel = context.WithTimeout(context.Background(), time.Second)
   goKey, err := cli.Get(ctx, "zl")
   if err != nil {
      fmt.Printf("get key faild,err:%v", err)
      return
   }

   for _, ev := range goKey.Kvs {
      fmt.Printf("key:%s,value:%s\n", ev.Key, ev.Value)
   }

   cancel()
}

使用ETCDCTL.exe操作的话，在操作前先设置环境变量
SET ETCDCTL_API=3
