## 描述

`proxy-control` 能够动态地控制 Nginx 代理的行为。

**这个插件需要 APISIX 在 [APISIX-Base](../FAQ.md#如何构建-APISIX-Base-环境？) 上运行。**

## 属性

| 名称      | 类型          | 必选项 | 默认值    | 有效值                                                                    | 描述                                                                                                                                         |
| --------- | ------------- | ----------- | ---------- | ------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| request_buffering | boolean        | 可选    |  true            |  | 动态设置 [`proxy_request_buffering`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_request_buffering) |

## 如何启用

以下是一个示例，在指定路由中启用插件：

```shell
curl -i http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/upload",
    "plugins": {
        "proxy-control": {
            "request_buffering": false
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
```

## 测试插件

使用 `curl` 去测试：

```shell
curl -i http://127.0.0.1:9080/upload -d @very_big_file
```

将不会在 error 日志中找到 "a client request body is buffered to a temporary file" 。

## 禁用插件

当您要禁用这个插件时，这很简单，您可以在插件配置中删除相应的 json 配置，无需重新启动服务，它将立即生效：

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/upload",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
```

现在就已经移除 `proxy-control` 插件了。其他插件的开启和移除也是同样的方法。
