service = 'es' # still es???
credentials = boto3.Session().get_credentials()
awsauth = AWS4Auth(credentials.access_key, credentials.secret_key, my_region, service, session_token=credentials.token)
openSearch_endpoint = config.openSearch_endpoint

# sth wrong here:
openSearch_client = OpenSearch(hosts = [openSearch_endpoint], auth = awsauth)

根据以下博客：

• https://docs.aws.amazon.com/opensearch-service/latest/developerguide/search-example.html

但它不起作用（它不想进行身份验证，"errorMessage":"AuthorizationException(403, '')"。但是，如果我不使用 python 客户端，而只是简单地执行requests以下操作：

import requests
host = config.openSearch_endpoint
url = host + '/' …
