无法解决python中的Elasticsearch.exceptions.SerializationError，无法从Elastic Search获取数据

Question

我已连接到远程ElasticSearch服务器，并尝试从中获取数据，但无法解决SerializationError。如果有人可以帮助我，那将是很棒的。赞赏使用Python的任何其他方法

  from elasticsearch import Elasticsearch, RequestsHttpConnection
  import certifi
    es = Elasticsearch( ['23t4t273545273547288fr8t83rtf8.us-east-1.aws.found.io'],
         https_auth=('userid', 'pwd'),

         connection_class= (RequestsHttpConnection),
         port=9200,
         use_ssl=True,
         verify_certs=True,
         ca_certs=certifi.where(),
      )
        if es.ping():
            print('Yay Connect')
        else:
            print('Awww it could not connect!')


     search_param = {
        "query": {
            "terms": {
                "contentType": "criteria"
             }
            }
           }

response = es.search(index="content-page-rwr-v1", body=search_param)


print ('response:', response)

我在python中收到以下错误

Yay Connect
Traceback (most recent call last):
File "Q:/MIS-DEV/QA/Pranit/PyCharm Projects/ALL Orig Scripts/ES.py", line 175, in <module>
response = es.search(index="content-page-rwr-v1", body=search_param)

raise SerializationError('Unknown mimetype, unable to deserialize: %s' % mimetype)
elasticsearch.exceptions.SerializationError: Unknown mimetype, unable to deserialize: text/html

提前谢谢您

我相信正在发生的事情是ES <6.0期望在标头（特别是application / json）中显式设置内容类型。您可以按照this github issue

中的建议修改连接类以执行此操作
