ECStore图片云端集群存储实践－又拍云存储

通过又拍云存储REST API ,为ECStore新增图片存储引擎，从而达到图片数据与主站数据分离。提高网站性能。

1. 图片存储引擎相关文件添加与修改

 一共涉及到ECStore 2个APP 的文件添加和修改。

 新增 ：app/base/lib/storage/upyunclass.php

<?php

    public function __construct($message, $code, Exception $previous = null) {

注意：此文件内有upyun权限及图片空间域名信息，如直接使用此文件，请做修改！

修改：app/image/lib/clip.php 2处：

修改1：

修改2：

修改：app/image/model/image.php

修改config/config.php ECStore站点配置文件

修改(去除注释)#define('FILE_STORAGER','filesystem'); 为define('FILE_STORAGER','upyunsystem');

修改后实现功能

1. ECStore所有图片上传功能（在商品相册上传图片、在图片相册上传图片、在图库上传图片，统一会上传到upyun api指定帐户空间，并返回"随机已绑定域名+存储目录+图片后缀"形式的绝对URL
2. 商品批量重新生成图片将调用upyun API并生成对应尺寸图片绝对URL到对应图片尺寸数据库字段
3. 图库批量图片尺寸重新生成队列将调用upyun API并生成对应尺寸图片绝对URL到对应图片尺寸数据库字段

最终实现全站图片云端集群存储。
