go语言操作etcd,get 读取目录下所有的kv

package main

import (
    "github.com/coreos/etcd/clientv3"
    "time"
    "fmt"
    "context"
)

func main() {
    var (
        config clientv3.Config
        client *clientv3.Client
        err error
        kv clientv3.KV
        getResp *clientv3.GetResponse
    )

    config = clientv3.Config{
        Endpoints: []string{"192.168.1.1:2379"}, // 集群列表
        DialTimeout: 5 * time.Second,
    }

    // 建立一个客户端
    if client, err = clientv3.New(config); err != nil {
        fmt.Println(err)
        return
    }

    // 用于读写etcd的键值对
    kv = clientv3.NewKV(client)

    // 写入另外一个Job
    kv.Put(context.TODO(), "/nginx/logs/", "{...}")

    // 读取/cron/jobs/为前缀的所有key
    if getResp, err = kv.Get(context.TODO(), "/nginx/logs/", clientv3.WithPrefix()); err != nil {
        fmt.Println(err)
    } else {    // 获取成功, 我们遍历所有的kvs
        fmt.Println(getResp.Kvs)
    }
}
