python环境：python3.8.8

ES（elasticsearch）版本 7.1.1

1.进行https请求时，忽略ssl证书验证，将context赋值给ssl_context 即可

from elasticsearch import Elasticsearch
#查看证书位置
import ssl
##忽视证书
context = ssl._create_unverified_context()

ES =["127.0.0.1:9200"]
# 创建elasticsearch客户端
es = Elasticsearch(
    ES,
    http_auth=('username', 'passward'),##账号密码
    scheme="https",
    ssl_context=context,
)
index = "index"
print(es)
print(es.ping())
res = es.indices.exists(index = index)
print(res)

2.

elasticsearch.exceptions.UnsupportedProductError: The client noticed that the server is not a supported distribution of Elasticsearch

这里的问题是python中的elasticsearch 包的版本和 ES服务端的版本不匹配

可以改变python 中elasticsearch的版本,与服务端ES版本保持一致

pip uninstall elasticsearch
pip install elasticsearch==7.1

3.

ssl证书报警

# 加上这行代码即可，关闭安全请求警告
