elasticsearch python bulk api（elasticsearch-py）

Question

我对py-elasticsearch批量@Diolor解决方案的工作很困惑https://stackoverflow.com/questions/20288770/how-to-use-bulk-api-to-store-the-keywords-in-es-by-using -python ，但我想使用普通的es.bulk（）

我的代码：

from elasticsearch import Elasticsearch
es = Elasticsearch()
doc = '''\n {"host":"logsqa","path":"/logs","message":"test test","@timestamp":"2014-10-02T10:11:25.980256","tags":["multiline","mydate_0.005"]} \n'''
result = es.bulk(index="logstash-test", doc_type="test", body=doc)

错误是：

 No handlers could be found for logger "elasticsearch"
Traceback (most recent call last):
  File "./log-parser-perf.py", line 55, in <module>
    insertToES()
  File "./log-parser-perf.py", line 46, in insertToES
    res = es.bulk(index="logstash-test", doc_type="test", body=doc)
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch-1.0.0-py2.7.egg/elasticsearch/client/utils.py", line 70, in _wrapped
    return func(*args, params=params, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch-1.0.0-py2.7.egg/elasticsearch/client/__init__.py", line 570, in bulk
    params=params, body=self._bulk_body(body))
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch-1.0.0-py2.7.egg/elasticsearch/transport.py", line 274, in perform_request
    status, headers, data = connection.perform_request(method, url, params, body, ignore=ignore)
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch-1.0.0-py2.7.egg/elasticsearch/connection/http_urllib3.py", line 57, in perform_request
    self._raise_error(response.status, raw_data)
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch-1.0.0-py2.7.egg/elasticsearch/connection/base.py", line 83, in _raise_error
    raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info)
elasticsearch.exceptions.TransportError: TransportError(500, u'ActionRequestValidationException[Validation Failed: 1: no requests added;]')

POST调用生成的URL是

/ logstash测试/检验/ _bulk

POST主体是：

{“host”：“logsqa”，“path”：“/ logs”，“message”：“test test”，“@ timestamp”：“2014-10-02T10：11：25.980256”，“tags”：[“多”， “mydate_0.005”]}

所以我手工卷曲：这种卷曲不起作用：

> curl -XPUT http://localhost:9200/logstash-test/test2/_bulk -d
> '{"host":"logsqa","path":"/logs","message":"test
> test","@timestamp":"2014-10-02T10:11:25.980256","tags":["multiline","mydate_0.005"]}
> '
>
> {"error":"ActionRequestValidationException[Validation Failed: 1: no requests added;]","status":500}

所以错误部分正常，但我确实期望elasticsearch.bulk（）将正确管理输入参数。

pythonf函数是：

bulk(*args, **kwargs)
    :arg body: The operation definition and data (action-data pairs), as
        either a newline separated string, or a sequence of dicts to
        serialize (one per row).
    :arg index: Default index for items which don't provide one
    :arg doc_type: Default document type for items which don't provide one
        :arg consistency: Explicit write consistency setting for the operation
    :arg refresh: Refresh the index after performing the operation
    :arg routing: Specific routing value
    :arg replication: Explicitly set the replication type (default: sync)
    :arg timeout: Explicit operation timeout

如果有人正在尝试使用批量api并想知道格式应该是什么，这对我有用：

doc = [
    {
        'index':{
            '_index': index_name,
            '_id' : <some_id>,
            '_type':<doc_type>
        }
    },
    {
        'field_1': <value>,
        'field_2': <value>
    }
]

docs_as_string = json.dumps(doc[0]) + '\n' + json.dumps(doc[1]) + '\n'
client.bulk(body=docs_as_string)

嗨sirkubax，

批量api（和所有其他的一样）非常接近弹性搜索本身的批量api格式，所以主体必须是：

doc ='''{“index”：{}} \\ n {“host”：“logsqa”，“path”：“/ logs”，“message”：“test test”，“@ timestamp”：“2014- 10-02T10：11：25.980256“，”标签“：[”multiline“，”mydate_0.005“]} \\ n'''它可以工作。 或者它可以是这两个词的列表。

这是一个复杂而笨拙的格式，可以使用python，这就是为什么我尝试在elasticsearch.helpers.bulk（0）中创建一个更方便的方法来处理批量。 它只接受文档的迭代器，将从中提取任何可选元数据（如_id，_type等）并构造（并执行）批量请求。 有关接受格式的更多信息，请参阅上面的streaming_bulk文档，该文档是以迭代方式处理流的帮助程序（从用户点开始一次一个，在后台以块的形式批处理）。

希望这可以帮助。
