Python3 操作Elasticsearch，獲取xpack的license信息

一.下載依賴模塊

# pip3 install elasticsearch elasticsearch-xpack

二.實例代碼

 

#!/usr/bin/python3

#--coding:utf-8--

from elasticsearch import Elasticsearch

from elasticsearch_xpack import LicenseClient

es = Elasticsearch(

    ['IP_HOST:9200'],

    http_auth=('用戶名','密碼')

)

xpack = LicenseClient(es)

print(xpack.get())

ps:過程中網上的方法不全，還是需要通過查詢模塊的用法結合模塊源碼來編寫方法
