下面是我的代码-
Elasticsearch没有使用https协议，而是使用http协议。

pip uninstall elasticsearch
pip install elasticsearch==7.13.4
import elasticsearch.helpers
from elasticsearch import Elasticsearch

# from elasticsearch import Elasticsearch, RequestsHttpConnection

es_host = '<>'
es_port = '<>'
es_username = '<>'
es_password = '><'
es_index = '<>'

es = Elasticsearch([{'host':str(es_host),'port':str(es_port)}], http_auth=(str(es_username), str(es_password)))

es.indices.refresh(index=es_index)

错误-

10 es = Elasticsearch([{'host': str(es_host), 'port': str(es_port)}],http_auth=(str(es_username), str(es_password)))
     11 
     12 es.indices.refresh(index=es_index)

TypeError: __init__() missing 1 required positional argument: 'scheme'

当我加上“方案”
代码-

es = Elasticsearch([{'host':str(es_host),'port':str(es_port)}], http_auth=(str(es_username), str(es_password)), scheme="http",verify_certs=False)

错误-

__init__() got an unexpected keyword argument 'scheme'

我检查并尝试连接到ES，但它没有连接。
