注：镜像请求返回的响应会被忽略。

### 参数

|名称    |必须|类型|描述|
|------- |-----|------|------|
|host|是|string|指定镜像服务地址，例如：http://127.0.0.1:9797（地址中需要包含 schema ：http或https，不能包含 URI 部分）|

### 示例

#### 启用插件

示例1：为特定路由启用 `proxy-mirror` 插件：

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "plugins": {
        "proxy-mirror": {
           "host": "http://127.0.0.1:9797"
        }
    },
    "upstream": {
        "nodes": {
            "127.0.0.1:1999": 1
        },
        "type": "roundrobin"
    },
    "uri": "/hello"
}'
```

测试：

```shell
$ curl http://127.0.0.1:9080/hello -i
HTTP/1.1 200 OK
Content-Type: application/octet-stream
Content-Length: 12
Connection: keep-alive
Server: APISIX web server
Date: Wed, 18 Mar 2020 13:01:11 GMT
Last-Modified: Thu, 20 Feb 2020 14:21:41 GMT

hello world
```

> 由于指定的 mirror 地址是127.0.0.1:9797，所以验证此插件是否已经正常工作需要在端口为9797的服务上确认，例如，我们可以通过 python 启动一个简单的 server： python -m SimpleHTTPServer 9797。

#### 禁用插件

移除插件配置中相应的 JSON 配置可立即禁用该插件，无需重启服务：

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1999": 1
        }
    }
}'
```

这时该插件已被禁用。
