ElasticsearchWarning：[删除类型] 不推荐在文档索引请求中指定类型，请改用无类型端点

Question

我应该在我的脚本中使用什么无类型端点，我想索引给定目录中的 json 文件。遇到一个小错误，搜索了很多但没有任何线索。 完整的错误：

C:\Users\USER\AppData\Local\Programs\Python\Python310\lib\site-packages\elasticsearch\connection\base.py:209: ElasticsearchWarning: [types removal] Specifying types in document index requests is deprecated, use the typeless endpoints instead (/{index}/_doc/{id}, /{index}/_doc, or /{index}/_create/{id}).
  warnings.warn(message, category=ElasticsearchWarning)

我的脚本：

import requests, json, os
from elasticsearch import Elasticsearch

#folder containing the json folders of scraped data
directory = '../spider/'

#Elasticsearch instance will listen on port 9200
res = requests.get('http://localhost:9200')
print (res.content)
es = Elasticsearch([{'host': 'localhost', 'port': '9200'}])

#index value object to iterate over the JSON files
i = 1

#Iterate over each JSON file and load it into Elasticsearch
for filename in os.listdir(directory):
    if filename.endswith(".json"):
        fullpath=os.path.join(directory, filename)
        f = open(fullpath)
        docket_content = f.read()
        # Send the data into es
        es.index(index='myIndex', ignore=400, doc_type='docket', id=i, document=json.loads(docket_content),)
        i = i + 1

这是我第一次尝试 Elasticsearch，我很笨，解决方案已经被应用了。

您需要将doc_type='docket' 更改为doc_type='_doc'，它将与您所拥有的一起工作
