Python 用反斜杠查询 ElasticSearch 路径

Question

我正在使用 Python 的弹性搜索扩展，试图查询特定路径。

这是我封装的查询：

{
"size": 1000,
 "query": {
   "filtered": {
     "filter": {
       "bool": {
         "must": [
           {
             "term": {
               "Path": "c:\myfolder\myfile.txt"
             }
           }
         ]
       }
     }
   }
 }
}

在 kopf 插件中工作正常。

这是我的 Python 代码：

from elasticsearch import Elasticsearch
es = Elasticsearch(hosts=['my_server'])
index = "my_index"
query = '{"size":1000,"query":{"filtered":{"filter":{"bool":{"must":[{"term":{"Path":"c:\myfolder\myfile.txt"}}]}}}}}'
response = es.search(index=index, body=query)

出于某种原因，我遇到了这个错误（没有反斜杠就不会发生）：

/usr/local/lib/python2.7/dist-packages/elasticsearch/client/utils.py", line 69, in _wrapped return func(*args, params=params, **kwargs) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/client/init.py", line 530, in search doc_type, '_search'), params=params, body=body) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/transport.py", line 329, in perform_request status, headers, data = connection.perform_request(method, url, params, body, ignore=ignore, timeout=timeout) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/connection/http_urllib3.py", line 106, in perform_request self._raise_error(response.status, raw_data) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/connection/base.py", line 105, in _raise_error raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info) elasticsearch.exceptions.RequestError

这个问题只有在有反斜杠的时候才会出现。

注意：我正在研究 Ubuntu。

提前致谢。

尝试将 "Path" 更改为 c:\\myfolder\\myfile.txt。
