python 中的 Elasticsearch 更新文档

Question

我正在尝试更新 elasticsearch 中的文档 python、

from elasticsearch import Elasticsearch
from datetime import datetime
from scapy.all import *
import json
# es = Elasticsearch()
es = Elasticsearch(['http://localhost:9200'])

doc = getDoc("1")
    print doc
    if doc != None:
      doc['_op_type'] = 'update'
      doc['_source']['macList'].append('new')
      helpers.bulk(es, doc, stats_only=False)

但这不起作用。有人可以告诉我我做错了什么吗？谢谢

这是错误：

Traceback (most recent call last):
  File "./req.py", line 48, in <module>
    helpers.bulk(es, doc, stats_only=False)
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch/helpers/__init__.py", line 188, in bulk
    for ok, item in streaming_bulk(client, actions, **kwargs):
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch/helpers/__init__.py", line 160, in streaming_bulk
    for result in _process_bulk_chunk(client, bulk_actions, raise_on_exception, raise_on_error, **kwargs):
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch/helpers/__init__.py", line 89, in _process_bulk_chunk
    raise e
elasticsearch.exceptions.RequestError: TransportError(400, u'action_request_validation_exception', u'Validation Failed: 1: index is missing;2: type is missing;3: index is missing;4: type is missing;5: index is missing;6: type is missing;7: index is missing;8: type is missing;9: index is missing;10: type is missing;11: index is missing;12: type is missing;13: index is missing;14: type is missing;')

更新我试过这个：es.update(index='macs', doc_type='users', id="1", body=doc) 我遇到了这个错误：追溯（最近一次通话最后一次）：

  File "./req.py", line 50, in <module>
    es.update(index='macs', doc_type='users', id="1", body=doc)
  File "/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 460, in update
    doc_type, id, '_update'), 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 109, in perform_request
    self._raise_error(response.status, raw_data)
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch/connection/base.py", line 108, in _raise_error
    raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info)
elasticsearch.exceptions.RequestError: TransportError(400, u'action_request_validation_exception', u'Validation Failed: 1: script or doc is missing;').

用 postman 很容易，但我真的不明白为什么用 Elasticsearch (python) 来更新 doc。有人有其他想法可以帮助吗？

Answer 1

由于 helpers.bulk() 方法中的第二个参数应该是一个 iterable，请尝试将其包含在列表中。

另外查看您的代码，您似乎只希望 getDoc() 函数提供一份文档。所以如果你使用简单的 es.update() 方法而不是使用 helpers.bulk()

会更好

Answer 2

解决方案对我有用。

doc= ess.get(...) 
# modify my doc and ...   
coll = Elasticsearch()
coll.update(index='stories-test',doc_type='news',id=hit.meta.id,
                    body= {"doc": doc['_source']} )

Answer 3

（万一有人遇到类似问题，）我遇到了上面提到的第一个错误：

elasticsearch.exceptions.RequestError: TransportError(400, 
'action_request_validation_exception', 'Validation Failed: 
1: index is missing;2: type is missing;

下面为我修复了它：

obj.to_dict(include_meta=True)

在将 obj 转换为 dict 时，我添加了 include_meta=True，它对我有用。
