只有100多行PHP 代码的七牛云离线下载

下载谷歌上面的android studio的程序包，速度实在太慢了。然后弄了个 php+shell 脚本的七牛云下载和 for codeigniter 版本的。今天又花了点时间来整理成 PHP 的。（PS：有个写法是用??这种 PHP7的新特征，可自行修改成 PHP5的）首发于：https://www.zzzzy.com/201605084032.html 持续更新 Github: [https://github.com/skiy/dev/blob/master/api/qiniu.php](https://github.com/skiy/dev/blob/master/api/qiniu.php)```<?php/** * 七牛云离线下载 * qiniu.php * @author  : Skiychan  * @link    : https://www.zzzzy.com * @created : 5/8/16 * @modified: * @version : 0.0.1 * @doc     : https://www.zzzzy.com/201605084032.html * 用了点 PHP7的新特征：?? 和 PHP5高版本的 [] 代替 array()，可自行修改 */$thisPage = basename($_SERVER['PHP_SELF']);if (empty($_POST)) {    ?>
