extend a method `ctx.downloader` to download file

## Install

```bash

$ npm i egg-downloader --save

```

## Usage

```js

// {app_root}/config/plugin.js

exports.downloader = {

  enable: true,

  package: 'egg-downloader',

};

```

## Features

`ctx.downloader`用于提供文件下载的功能，支持三个参数，ctx.download(file, [name], [header]) 

  

  * file: 必选，文件路径

  * name: 可选，下载文件名（包含后缀）

  * header: 可选，附加头信息, 并且header会改为全部小写（感谢[天猪](https://github.com/atian25)的建议：egg 推荐 header 全部小写，会有一定的性能提升）。

> 如果 file 是个不带路径的文件，将默认视为下载 app/public/file 。

## Example

```js

// {app_root}/controller/home.js

const Controller = require('egg').Controller;

class HomeController extends Controller {

  async index() {

    // 下载为 package.json

    this.ctx.downloader('./package.json');

    

    // 下载为 new-name.json

    // this.ctx.downloader('package.json', 'new-name.json');

    

    // 下载为 new-name.json, header: X-Token: 123

    // this.ctx.downloader('package.json', 'new-name.json', { 'x-token': '123' });

  }

}

module.exports = HomeController;

```
