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、清楚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楚操作。
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
建议使用子秘钥
三、编写代码
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2019/10/29 0029 * Time: 10:10 */ namespace app\index\controller; use AlibabaCloud\Client\AlibabaCloud; use AlibabaCloud\Client\Exception\ClientException; use AlibabaCloud\Client\Exception\ServerException; use think\Controller; use think\Request; class Cdn extends Controller { protected $accessKeyId; protected $accessSecret; public function __construct(Request $request = null) { parent::__construct($request); $this->accessKeyId = '123456789'; $this->accessSecret = '123456789'; } public function index() { $url = 'http://www.demo.com/css/index.css'; // Download:https://github.com/aliyun/openapi-sdk-php // Usage:https://github.com/aliyun/openapi-sdk-php/blob/master/README.md AlibabaCloud::accessKeyClient($this->accessKeyId, $this->accessSecret) ->regionId('cn-hangzhou') ->asDefaultClient(); try { $result = AlibabaCloud::rpc() ->product('Cdn') // ->scheme('https') // https | http ->version('2018-05-10') ->action('RefreshObjectCaches') ->method('POST') ->host('cdn.aliyuncs.com') ->options([ 'query' => [ 'RegionId' => "cn-hangzhou", 'ObjectPath' => $url, ], ]) ->request(); $res = $result->toArray(); if(isset($res['RefreshTaskId'])) { echo '刷新成功'; } else { echo '刷新失败'; } } catch(ClientException $e) { echo $e->getErrorMessage() . PHP_EOL; } catch(ServerException $e) { echo $e->getErrorMessage() . PHP_EOL; } } }
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!
