阿里云CDN刷新链接接口实践

今天更改了一个线上的css文件，由于项目部署了cdn，需要对缓存进行清理。有两种方式;

一、清除cdn缓存

二、更改页面引入文件地址，如加入版本号

第一种方式需要登录阿里云，然后进行缓存清理操作，比较麻烦;

第二种方式如果是涉及的页面数量过多，在更改起来也是非常麻烦的。

我们使用的阿里云的cdn产品，记得以往的产品都有api接口，想通过阿里云cdn接口模式对链接进行缓存清除操作。

下面是php实例：

一、安装SDK

使用composer进行安装，命令：

composer require alibabacloud/client

二、获取阿里云参数

1、accessKeyId

2、accessSecret

建议使用子密钥

建议在提交刷新后，2分钟后查看效果，注意要清除浏览器缓存哦!
