Elasticsearch Java Rest Client:如何获取所有索引的列表 [英] Elasticsearch Java Rest Client: how to get the list of all indices

问题描述

如何使用Rest Client在Elasticsearch中获取所有索引的列表?

How do I get the list of all indices in Elasticsearch using the Rest Client?

(我在网上找到的所有答案似乎都与旧类型的客户有关.

(All answers I've found online seem to deal with the old type of client.

我无法在文档中找到直接答案，

I fail to find the direct answer in the doc,

https://www.elastic.co/guide/zh-CN/elasticsearch/client/java-rest/current/index.html

无法确定要查找哪个部分，无论是集群API还是索引API等.

can't figure out which section to look into, either Cluster or Index APIs etc.)

推荐答案

通过REST API，您可以使用以下URL进行验证:

Via the REST API you can verify with this URL : http://elasticsearch:9200/_cat/indices?v

通过Java Client API(我才刚刚意识到您是这样问的):您可以押注Cluster Health API:

Via the Java Client API (I just realised you asked this way) : you can bet on the Cluster Health API : https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-cluster-health.html

并使用

ClusterHealthRequest request = new ClusterHealthRequest();
ClusterHealthResponse response = client.cluster().health(request, RequestOptions.DEFAULT);
Set<String> indices = response.getIndices().keySet();

您将获得索引列表;)
