Elasticsearch Nest 6-获取索引元数据

您可以使用

var defaultIndex = "default-index";
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));

var settings = new ConnectionSettings(pool)
    .DefaultIndex(defaultIndex);

var client = new ElasticClient(settings);

var mappingResponse = client.GetMapping<MyDocument>();

它将向发送请求

GET http://localhost:9200/default-index/_mapping/mydocument

在这种情况下

• index 将 "default-index"
• type 将 "mydocument" ,从POCO类型推断 MyDocument

var mappingResponse = client.GetMapping<MyDocument>(m => m
    .Index("foo")
    .Type("bar")
);

哪个发送以下请求

GET http://localhost:9200/foo/_mapping/bar

以及目标 和/或 所有类型

var mappingResponse = client.GetMapping<MyDocument>(m => m
    .AllIndices()
    .AllTypes()
);

哪个发送以下请求

GET http://localhost:9200/_mapping
