How to get a list of all indexes in python-elasticsearch
提问by David542
How would I get a list of the names of an index in Python? Here is what I have so far:
我如何获得 Python 中索引名称的列表？这是我到目前为止所拥有的：
>>> es=e.es
>>> es
<Elasticsearch([{'host': '14555f777d8097.us-east-1.aws.found.io', 'port': 9200}])>
>>> es.indices
<elasticsearch.client.indices.IndicesClient object at 0x10de86790>
# how to get a list of all indexes in this cluster?

This question comes up when searching for information on retrieving aliasesusing the python-elasticsearchlibrary. The accepted answer says to use get_aliasesbut that method has been removed (as of 2017). To get aliases, you can use the following:
在搜索有关aliases使用python-elasticsearch库检索的信息时会出现此问题。接受的答案说要使用，get_aliases但该方法已被删除（截至 2017 年）。要获取aliases，您可以使用以下方法：
es.indices.get_alias("*")

I use curl to call the stats API and get information about the indices. Then I parse the JSON object that is returned to find the index names.
我使用 curl 调用 stats API 并获取有关索引的信息。然后我解析返回的 JSON 对象以查找索引名称。
curl localhost:9200/_stats
In Python you can call curl using the requests library. I don't know of a way to do this using the Elasticsearch or Elasticsearch-DSL Python library.
在 Python 中，您可以使用 requests 库调用 curl。我不知道有什么方法可以使用 Elasticsearch 或 Elasticsearch-DSL Python 库来做到这一点。

Here is one way to do it with the get_alias()method:
这是使用该get_alias()方法执行此操作的一种方法：
>>> indices=es.indices.get_alias().keys()
>>> sorted(indices)
[u'avails', u'hey', u'kibana-int']

You can get _mapping to get list of all indexes by doing something like that.
您可以通过执行类似操作来获取 _mapping 以获取所有索引的列表。
requests.get(full_elastic_url + "/_mapping")

If you are willing to use pyelasticsearch modulethey have support for the GET _mappingcommand, which produces the schema of the cluster. This will allow you to see the indices, and drill into each index to see doc_types, and their fields, etc. Here's an example:
如果您愿意使用pyelasticsearch 模块，它们会支持该GET _mapping命令，该命令会生成集群的架构。这将允许您查看索引，并深入查看每个索引以查看 doc_types 及其字段等。这是一个示例：
import pyelasticsearch as pyes
es = pyes.ElasticSearch(["http://hostname0:9200", "http://hostname1:9200"]) ## don't accidentally type Elasticsearch, the class from the other two modules
schema = es.get_mapping() ## python dict with the map of the cluster
To get just the list of indices,
只获取索引列表，
indices_full_list = schema.keys()
just_indices = [index for index in indices_full_list if not index.startswith(".")] ## remove the objects created by marvel, e.g. ".marvel-date"

如何获取该集群中所有索引的列表？
Use the wildcard. Works with elasticsearch-py.
使用通配符。与 elasticsearch-py 一起使用。
for index in es.indices.get('*'):
print index
