先用 go get go.etcd.io/etcd/clientv3 获得etcd的客户端

下面为测试代码
package main

import (

"fmt"
"time"

"go.etcd.io/etcd/clientv3"
context "golang.org/x/net/context"

)

func main() {

cli, err := clientv3.New(clientv3.Config{
    Endpoints:   []string{"localhost:2379", "localhost:22379", "localhost:32379"},
    DialTimeout: 5 * time.Second,
})
if err != nil {
    fmt.Println("clientv3.New faild", err)
    return
}
fmt.Println("clientv3.New success")
defer cli.Close()

ctx, cancel := context.WithTimeout(context.Background(), time.Second*50)
defer cancel()
i := 0
for {
    resp, err := cli.Put(ctx, fmt.Sprintf("sample_key_%d", i), "sample_value")

    if err != nil {
        fmt.Println("clientv3 put key faild", err)
        return
    }

    fmt.Println("clientv3 put key  success, return", resp)

    if i == 10 {
        break
    }
    i++
    time.Sleep(time.Second)
}

time.Sleep(time.Second * 3)

}
