elasticsearch - Elasticsearch按查询删除API:Curl正常运行，但无法使用Python(请求)实现相同功能？

Question

我正在使用Delete By Query API删除一堆文件。下面的 curl 是完美的工作:

POST /tom-access/doc/_delete_by_query
{
  "query": {
    "terms": {
      "_id": [
        "xxxxx",
        "yyyyy"
      ]
    }
  }
}

现在，我想利用Python中的 requests库实现相同的功能。

import requests,json

url = "http://elastic.tool.com:80/tom-access/doc/_delete_by_query"
headers = {"Content-type": "application/json", "Accept": "application/json", "Authorization": "Basic asdadsasdasdasd"}

data = {
        'query':{
                'terms':{
                        '_id':[
                                'xxxxx',
                                'yyyyy'
                        ]
                }
        }
}

try:
    r = requests.post(url,
                 headers=headers,
                 data=data,
                 verify=False)
except blablaaa

response_dict = r.json()
print(response_dict)

我得到以下错误:

{'error': {'root_cause': [{'type': 'json_parse_exception', 'reason': "Unrecognized token 'query': was expecting ('true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@bc04803; line: 1, column: 7]"}], 'type': 'json_parse_exception', 'reason': "Unrecognized token 'query': was expecting ('true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@bc04803; line: 1, column: 7]"}, 'status': 500}

我究竟做错了什么？

我认为您应该尝试在""变量中使用双引号(data)而不是单引号('')。另外，使用json.dumps()转换查询。
这是https://marcobonzanini.com/2015/02/02/how-to-query-elasticsearch-with-python/的示例，其中显示了requests库的用法:

def search(uri, term):
    """Simple Elasticsearch Query"""
    query = json.dumps({
        "query": {
            "match": {
                "content": term
            }
        }
    })
    response = requests.get(uri, data=query)
    results = json.loads(response.text)
    return results
