## 描述

`node-status` 是 `APISIX` 的请求状态查询插件，返回基本的状态信息。

## 插件属性

无。

## 插件接口

插件增加接口 `/apisix/status`，需要通过 [public-api](../../../en/latest/plugins/public-api.md) 插件来暴露它。

## 启用插件

1. 配置文件 `conf/config.yaml` 的 plugin list 中配置 `node-status`

```
plugins:                          # plugin list
  - example-plugin
  - limit-req
  - node-status
  - jwt-auth
  - zipkin
  ......
```

2. 为状态 API 配置路由，它将使用 [public-api](../../../en/latest/plugins/public-api.md) 插件。

```shell
$ curl http://127.0.0.1:9080/apisix/admin/routes/ns -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/apisix/status",
    "plugins": {
        "public-api": {}
    }
}'
```

## 测试插件

1. 发送请求

```sh
$ curl localhost:9080/apisix/status -i
HTTP/1.1 200 OK
Date: Tue, 03 Nov 2020 11:12:55 GMT
Content-Type: text/plain; charset=utf-8
Transfer-Encoding: chunked

{"status":{"total":"23","waiting":"0","accepted":"22","writing":"1","handled":"22","active":"1","reading":"0"},"id":"6790a064-8f61-44ba-a6d3-5df42f2b1bb3"}
```

2. 参数说明

## 禁用插件

1. 配置文件 `apisix/conf/config.yaml` 的 plugin list 中删除 `node-status`

```
plugins:                          # plugin list
  - example-plugin
  - limit-req
  - jwt-auth
  - zipkin
  ......
```

2. 删除 route 中的 `node-status` 插件信息

```sh
$ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
{
    "uri": "/route1",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "192.168.1.100:80": 1
        }
    },
    "plugins": {}
}'
```
