解决golang使用elastic连接elasticsearch时自动转换连接地址

 elastic.SetSniff(false)

client, _ := elastic.NewClient(
  // ...
  // 将sniff设置为false后，便不会自动转换地址
   elastic.SetSniff(false),
)

var client *elastic.Client

var host = "http://xxx:9200"

//初始化es驱动
func init() {

   errorlog := log.New(os.Stdout, "app", log.LstdFlags)

   var err error
   client, err = elastic.NewClient(elastic.SetErrorLog(errorlog), elastic.SetURL(host), elastic.SetSniff(false))
   if err != nil {
      panic(err)
   }
   info, code, err := client.Ping(host).Do(context.Background())
   if err != nil {
      panic(err)
   }
   fmt.Printf("Es return with code %d and version %s \n", code, info.Version.Number)
   esversionCode, err := client.ElasticsearchVersion(host)
   if err != nil {
      panic(err)
   }
   fmt.Printf("es version %s\n", esversionCode)
}
