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 '', //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
);

}使用方法也比较简单，如果只有一个bucket则可以把配置写入config.php里，内容如下'file_upload_type' => 'oss',
'upload_type_config' => array(
'access_id' => 'access_id', //阿里云access key id
'access_key' => 'access_key', //阿里云access key secret
'bucket' => 'bucket' //阿里云的bucket
),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(
'maxsize' => 0,
'exts' => array('jpg', 'jpeg', 'png'),
'savename' => array('uniq_photo_name', '__file__'),
'rootpath' => '/',
);
$oss_config = array(
'access_id' => 'access_id', //阿里云access key id
'access_key' => 'access_key', //阿里云access key secret
'bucket' => 'bucket'
);
$upload = new \think\upload($config, 'oss', $oss_config);
