不用加载官方那一大坨sdk了，简单一点
看过网上的一些例子都过于复杂，包含了官方的phpsdk那一大坨东西，理论上我只需要简单的上传文件而已，不需要那么多东西，于是自己写了一下。

以下代码保存到/yourpath/ThinkPHP/Library/Think/Upload/Driver/Oss.class.php即可<?php // +---------------------------------------------------------------------- // | ThinkPHP [ WE CAN DO IT JUST THINK IT ] // +---------------------------------------------------------------------- // | Copyright (c) 2006-2014 http://thinkphp.cn All rights reserved. // +---------------------------------------------------------------------- // | Licensed ( http://www.apache.org/licenses/LICENSE-2.0 ) // +---------------------------------------------------------------------- // | Author: 废墟 <r.anerg> <http:> // +---------------------------------------------------------------------- namespace Think\Upload\Driver; class Oss { const OSS_HOST = 'oss.aliyuncs.com'; /** * 上传文件根目录 * @var string */ private $rootPath; /** * 上传错误信息 * @var string */ private $error = ''; private $config = array( 'access_id' => '', //阿里云Access Key ID 'access_key' => '', //阿里云Access Key Secret 'bucket' => '', //空间名称 'timeout' => 90, //超时时间 ); /** * 构造函数，用于设置上传根路径 * @param array $config FTP配置 */ public function __construct($config) { /* 默认FTP配置 */ $this->config = array_merge($this->config, $config); } /** * 检测上传根目录(阿里云上传时支持自动创建目录，直接返回) * @param string $rootpath 根目录 * @return boolean true-检测通过，false-检测失败 */ public function checkRootPath($rootpath) { /* 设置根目录 */ $this->rootPath = trim($rootpath, './') .
