from elasticsearch import Elasticsearch
obj = Elasticsearch()
# 创建索引（Index）
result = obj.indices.create(index=\'user\', body={"userid":\'1\',\'username\':\'lqz\'},ignore=400)
# print(result)
# 删除索引
# result = obj.indices.delete(index=\'user\', ignore=[400, 404])
# 插入数据
# data = {\'userid\': \'1\', \'username\': \'lqz\',\'password\':\'123\'}
# result = obj.create(index=\'news\', doc_type=\'politics\', id=1, body=data)
# print(result)
