ElasticSearch之Get index API

获取指定索引的基本信息。

命令样例如下：

curl -X GET "https://localhost:9200/testindex_001?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果的样例，如下：

{
  "testindex_002" : {
    "aliases" : { },
    "mappings" : { },
    "settings" : {
      "index" : {
        "routing" : {
          "allocation" : {
            "include" : {
              "_tier_preference" : "data_content"
            }
          }
        },
        "number_of_shards" : "3",
        "provided_name" : "testindex_002",
        "creation_date" : "1701498436722",
        "number_of_replicas" : "2",
        "uuid" : "k6twq9y9Qtmcs2AHK-USEQ",
        "version" : {
          "created" : "8500003"
        }
      }
    }
  }
}

假如索引不存在，执行结果的样例，如下：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "index_not_found_exception",
        "reason" : "no such index [testindex_003]",
        "resource.type" : "index_or_alias",
        "resource.id" : "testindex_003",
        "index_uuid" : "_na_",
        "index" : "testindex_003"
      }
    ],
    "type" : "index_not_found_exception",
    "reason" : "no such index [testindex_003]",
    "resource.type" : "index_or_alias",
    "resource.id" : "testindex_003",
    "index_uuid" : "_na_",
    "index" : "testindex_003"
  },
  "status" : 404
}

方法参数

features，默认值为aliases,mappings,settings。

使用逗号分隔，可选值，如下：

• aliases
• mappings
• settings

flat_settings，使用展平的形式，呈现参数的名称。

include_defaults，指示响应中包含使用默认值的参数。

增加flat_settings和include_defaults，命令样例如下：

curl -X GET "https://localhost:9200/testindex_002?flat_settings=true&include_defaults=true&pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"
