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 <br />

'UPLOAD_TYPE_CONFIG' => array(<br>
'access_id' => 'access_id', //阿里云Access Key ID<br>
'access_key' => 'access_key', //阿里云Access Key Secret<br>
'bucket' => 'bucket' //阿里云的bucket<br>
),如果你需要将不同的文件存入不同的bucket则需要在上传方法中采用动态配置$config = array(<br>
'maxSize' => 0,<br>
'exts' => array('jpg', 'jpeg', 'png'),<br>
'saveName' => array('uniq_photo_name', '__FILE__'),<br>
'rootPath' => '/',<br>
);<br>
$oss_config = array(<br>
'access_id' => 'access_id', //阿里云Access Key ID<br>
'access_key' => 'access_key', //阿里云Access Key Secret<br>
'bucket' => 'bucket'<br>
);<br>
$upload = new \Think\Upload($config, 'Oss', $oss_config);
