## 分块传输编码 Chunk
## 返回文件下载
`Hyperf\HttpServer\Contract\ResponseInterface` 提供了 `download(string $file, string $name = '')` 返回一个已设置下载文件状态的 `Psr7ResponseInterface` 对象。
如果请求中带有 `if-match` 或 `if-none-match` 的请求头，Hyperf 也会跟根据协议标准与 `ETag` 进行比较，如果一致则会返回一个 `304` 状态码的响应。
`download` 方法：
| 参数 | 类型 | 默认值 | 备注 |
|:----:|:------:|:------:|:-------------------------------------------------------------------:|
| file | string | 无 | 要返回下载文件的绝对路径，同通过 BASE_PATH 常量来定位到项目的根目录 |
| name | string | 无 | 客户端下载文件的文件名，为空则会使用下载文件的原名 |
