## 查看API ##

JSON格式非常适合计算机，虽然打印得很好，但用户试图在数 据中查找到关系时也会感到乏味。人类的眼睛，尤其是在看终端时， 需要的是紧凑和对齐的文本。/\_cat旨在满足这一需求。

### 1、查看子目录 ###

\_cat/后不跟任何子节点，返回的结果是目录，也就是可用的 URL节点，这个功能是非常有用的，当忘记某个接口时可以先执行这 个接口。示例如下:

get /_cat

返回结果就是所有可用的Cat API：

/_cat/allocation
    /_cat/shards
    /_cat/shards/{
        index}
    /_cat/master
    /_cat/nodes
    /_cat/tasks
    /_cat/indices
    /_cat/indices/{
        index}
    /_cat/segments
    /_cat/segments/{
        index}
    /_cat/count
    /_cat/count/{
        index}
    /_cat/recovery
    /_cat/recovery/{
        index}
    /_cat/health
    /_cat/pending_tasks
    /_cat/aliases
    /_cat/aliases/{
        alias}
    /_cat/thread_pool
    /_cat/thread_pool/{
        thread_pools}
    /_cat/plugins
    /_cat/fielddata
    /_cat/fielddata/{
        fields}
    /_cat/nodeattrs
    /_cat/repositories
    /_cat/snapshots/{
        repository}
    /_cat/templates
    /_cat/transforms
    /_cat/transforms/{
        transform_id}

### 2、公共参数 ###

可以多个参数一起使用，用&连接

GET /_cat/indices?v&s=store.size:desc

#### 2.1、Verbose ####

每个命令都接受一个查询字符串参数v来打开详细输出。例如:

GET /_cat/master?v

id                     host      ip        node
    Cc6ARDA6TY-poOdtxvsA6g 127.0.0.1 127.0.0.1 zhangchenglongdeMacBook-Pro.local

#### 2.2、help ####

每个命令都接受一个查询字符串参数help，该参数将输出其可用 值。示例:

GET /_cat/master?help

id   |   | node id    
    host | h | host name  
    ip   |   | ip address 
    node | n | node name

#### 2.3、h ####

每个命令都接受一个查询字符串参数h，该参数只强制显示这些 列。示例

GET /_cat/nodes?h=ip,port,heapPercent,name

127.0.0.1 9300 35 zhangchenglongdeMacBook-Pro.local

#### 2.4、sort ####

指定输出的列进行排序，默认按照升序排序:

GET /_cat/indices/?v&s=pri,rep:desc

health status index                           uuid                   pri rep docs.count docs.deleted store.size pri.store.size
    yellow open   a                               G8WjS7PoQRG9kCQznaDmsg   1   1          1            0      3.4kb          3.4kb
    yellow open   recipes                         agtHN2npS2GE90N81xtjEA   1   1          9            0      4.8kb          4.8kb
    yellow open   b                               lnBia7kNQJOBAKvFLWefTg   1   1          1            0      3.6kb          3.6kb
    yellow open   log                             H3bResC1QyK-9hdZQ0gs0g   1   1          1            0      4.3kb          4.3kb
    yellow open   geo_shape

#### 2.5、format ####

指定响应返回的数据格式：text（默认）,json,yaml,smile,cbor  
（通过设置 Accept的HTTP头部的多媒体格式的优先级更高）

GET /_cat/master?format=json

[
      {
        
        "id" : "Cc6ARDA6TY-poOdtxvsA6g",
        "host" : "127.0.0.1",
        "ip" : "127.0.0.1",
        "node" : "zhangchenglongdeMacBook-Pro.local"
      }
    ]

### 3、常用接口 ###
