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：
aliasesmappingssettings
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"
