阿里云CDN的API操作

阿里云提供CDN的多种刷新方式，可以通过阿里云控制台刷新，也可以直接通过阿里云的SDK进行CDN刷新，本文主要记录使用JAVA API刷新CDN。
1.CDN操作前提是已经开通了阿里云CDN服务，拿到AccessKeyID和AccessKeySecret。
API说明手册
2.引入SDK，主要使用maven：

<dependency>  <groupId>com.aliyun</groupId>  <artifactId>aliyun-java-sdk-cdn</artifactId>  <version>2.2.3</version></dependency><dependency>  <groupId>com.aliyun</groupId>  <artifactId>aliyun-java-sdk-core</artifactId>  <version>3.0.6</version></dependency>

引入maven可以从阿里云上获取：
maven仓库：下载最新版本SDK
github源码库：这里写链接内容
3.初始化client：

public static void init() throws ClientException {        IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou",          "<your accessKey>", "<your accessSecret>");        client = new DefaultAcsClient(profile);    }

4.CDN API调用：

    /**     * 刷新资源方式-域名和资源路径分开     */    public static void purgeObjectCaches() {        PurgeObjectCachesRequest request = new PurgeObjectCachesRequest();        //要刷新的域名        request.setDomainName("<only your domain name>");        //要刷新的文件路径        request.setObjectPath("<file path in your domain>");        //刷新类型，默认是File,刷新目录为Directory        request.setObjectType("File");        //设置返回格式为JSON        request.setAcceptFormat(FormatType.JSON);        try {            HttpResponse httpResponse = client.doAction(request);            System.out.println(httpResponse.getUrl());            System.out.println(new String(httpResponse.getContent()));            System.out.println(httpResponse.getStatus());        } catch (ServerException e) {            e.printStackTrace();        } catch (ClientException e) {            e.printStackTrace();        }    }    /**     * 刷新资源方式-域名和资源路径不分开     */    public static void refreshObjectCaches() {        RefreshObjectCachesRequest request = new RefreshObjectCachesRequest();        //要刷新的URI        request.setObjectPath("<your complete resourse url>");        //刷新类型，默认是File,刷新目录为Directory        request.setObjectType("File");        //设置返回格式为JSON        request.setAcceptFormat(FormatType.JSON);        try {            HttpResponse httpResponse = client.doAction(request);            System.out.println(httpResponse.getUrl());            System.out.println(new String(httpResponse.getContent()));            System.out.println(httpResponse.getStatus());        } catch (ServerException e) {            e.printStackTrace();        } catch (ClientException e) {            e.printStackTrace();        }    }    /**     * 查询资源刷新纪录     */    public static void describeRefreshTasks() {        DescribeRefreshTasksRequest request = new DescribeRefreshTasksRequest();        //request.setTaskId("<your taskid>");        request.setObjectPath("<your complete url>");        request.setPageSize(10);        request.setPageNumber(1);        //设置返回格式为JSON        request.setAcceptFormat(FormatType.JSON);        try {            HttpResponse httpResponse = client.doAction(request);            System.out.println(httpResponse.getUrl());            System.out.println(new String(httpResponse.getContent()));            System.out.println(httpResponse.getStatus());    } catch (ServerException e) {        // TODO Auto-generated catch block        e.printStackTrace();    } catch (ClientException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    }    /**     * 查询CDN刷新剩余量     */    public static void describeRefreshQuota() {        DescribeRefreshQuotaRequest request = new DescribeRefreshQuotaRequest();        //设置返回格式为JSON        request.setAcceptFormat(FormatType.JSON);        try {            HttpResponse httpResponse = client.doAction(request);            System.out.println(httpResponse.getUrl());            System.out.println(new String(httpResponse.getContent()));            System.out.println(httpResponse.getStatus());        } catch (ServerException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (ClientException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }
