es 索引操作（创建、查看、删除）

创建

PUT /test01_demo

{ "settings": { "name": "张三" } }

Elasticsearch采用Rest风格API，因此其API就是一次http请求，只要能发起http请求。

settings：表示索引库设置，其中可以定义索引库的各种属性 比如分片数 副本数等，暂时不设置，都走默认。

判断索引是否存在

HEAD /test01_demo

查看索引

GET /索引名称

GET /test01_demo

批量查看索引

GET /索引名称1,索引名称2,索引名称3,…

GET /test01_demo1,test01_demo

查看所有索引

GET _all

信息就比较多了
