我正在尝试将 Django 应用程序从使用 AWS ElasticSearch 2.3 升级到 7.4（并同时升级 Django 包）。

我让它在本地运行，但是当我尝试使用 AWS ElasticSearch7.4 运行时，我得到以下 Traceback

Traceback (most recent call last):

我正在使用django-elasticsearch-dsl，所以我只是在其中声明了主机settings.py（这是我之前的直接替换）

ELASTICSEARCH_DSL = {
    'default': {
        'hosts': 'https://search-elastic7-zoqohjbiedz2ozmthfi4a3ccm4.eu-west-2.es.amazonaws.com', # I've changed this string
    },
}

我正在使用 IAM 身份验证，并且已授予 IAM 帐户对我所有 ElasticSearch 实例的完全访问权限（但这与我在设置实例时使用的主用户和密码不同）。如果我需要这些，我该如何通过它们？如果没有，我做错了什么？

如果其他人有问题，以下对其进行排序 

from elasticsearch import Elasticsearch, RequestsHttpConnection
from requests_aws4auth import AWS4Auth

AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID',"some key")
AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY',"another secret key")
AWS_SERVICE = 'es'
AWS_ELASTICSEARCH = os.environ.get('AWS_ELASTICSEARCH','search-elastic7-zoqohjbiedz2ozmthfi4a3ccm4.eu-west-2.es.amazonaws.com')
http_auth = AWS4Auth(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, AWS_SERVICE)
ELASTICSEARCH_DSL = {
    'default': {
        'hosts': [{'host': AWS_ELASTICSEARCH, 'port': 443}],
        'http_auth' : http_auth,
        'use_ssl' : True,
        'verify_certs' : True,
        'connection_class' : RequestsHttpConnection
    },

它看起来不像 django-elasticsearch-dsl 支持 AWS ES 请求签名，当您启用 IAM 身份验证时这是必需的： https ://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/es-request-签名.html

您可以通过使 AWS ES 实例完全打开（无身份验证）来检查这是否是问题所在。
