如何使用Elasticsearch DSL for python访问响应对象 [英] How to access the response object using elasticsearch DSL for python

问题描述

我有以下代码:

s = Search(using=Elasticsearch('http://user:passwd@ipaddress'), index="myindex")
q = Q("multi_match", query='some query', fields=['_all'])
s = s.query(q)

response = s.execute()
print('Total %d hits found.' % response.hits.total)
for hit in response:
    print(hit.title)

我得到了错误:

Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/elasticsearch_dsl/utils.py", line 102, in __getattr__
return _wrap(self._d_[attr_name])
KeyError: 'title'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "FindImage.py", line 89, in <module>
main(args.image_file)
File "FindImage.py", line 82, in main
query_db([1], [2])
File "FindImage.py", line 77, in query_db
print(hit.title)
File "/usr/local/lib/python3.5/dist-packages/elasticsearch_dsl/utils.py", line 105, in __getattr__
'%r object has no attribute %r' % (self.__class__.__name__, attr_name))
AttributeError: 'Result' object has no attribute 'title'

但是，这与文档所述内容直接矛盾:文档

However that is in direct contradiction to what the docs state: Docs

我做错了什么?如何从响应中正确提取匹配和我的值?

What am I doing wrong? How can I correctly extract the hits and my values from the response?

EDIT

EDIT

响应对象也应该具有方法"toDict"，但是当我尝试调用它时，我再次得到AttributeError.

Also the response object ist supposed to have a method "toDict" but when I try to call it I again get an AttributeError.

推荐答案

对于"toDict"问题， response.to_dict()对我有用.不知道此行为在lib版本之间是否相同.

For the "toDict" question, response.to_dict() works for me. Not sure if this behaviour is the same across lib versions.
