注: go-es包使用的是https://github.com/olivere/elastic

当es配置了ssl,但是证书是自签证书,那可能在操作初始化es-client时候会报这样错误

certificate signed by unknown authority

这个问题我在issue中找到了答案

可以通过配置httpclient来忽略ssl验证

最终改造结果如下

var client *elastic.Client
var host = "https://192.168.56.103:9200"
var userName = "elastic"
var passWord = "xiaowu"
