* 2. 请使用您的API授权密钥填充ACCESS_ID和ACCESS_KEY常量; * 3. 需要准确上传用的测试文件,并修改常量uploadFilePath为测试文件的路径; * 修改常量downloadFilePath为下载文件的路径。 * 4. 该程序仅为示例代码,仅供参考,并不能保证足够健壮。 *OSS Java API手册:http://aliyun_portal_storage.oss.aliyuncs.com/oss_api/oss_javahtml/index.html?spm=5176.7150518.1996836753.8.d5TjaG *OSS Java SDK开发包:http://help.aliyun.com/view/13438814.html *OSSClient:www.mvnrepository.com/artifact/cglib/cglib/2.2 *@author PineTree *@date 2014年12月1日 下午3:23:32 *@version */ public class TestOSS { /** * 阿里云ACCESS_ID */ private static String ACCESS_ID = "你的ACCESS_ID"; /** * 阿里云ACCESS_KEY */ private static String ACCESS_KEY = "你的ACCESS_KEY"; /** * 阿里云OSS_ENDPOINT 青岛Url */ private static String OSS_ENDPOINT = "http://oss-cn-qingdao.aliyuncs.com"; /** * 阿里云BUCKET_NAME OSS */ private static String BUCKET_NAME = "demo10"; public static void main(String[] args) { //String bucketName = "demo10"; String Objectkey = "photo1.jpg"; String uploadFilePath = "D:\\photo.jpg"; String downloadFilePath = "D:\\photo1.jpg"; // 使用默认的OSS服务器地址创建OSSClient对象,不叫OSS_ENDPOINT代表使用杭州节点,青岛节点要加上不然包异常 OSSClient client = new OSSClient(OSS_ENDPOINT, ACCESS_ID, ACCESS_KEY); //如果你想配置OSSClient的一些细节的参数,可以在构造OSSClient的时候传入ClientConfiguration对象。 //ClientConfiguration是OSS服务的配置类,可以为客户端配置代理,最大连接数等参数。 //具体配置看http://aliyun_portal_storage.oss.aliyuncs.com/oss_api/oss_javahtml/OSSClient.html#id2 //ClientConfiguration conf = new ClientConfiguration(); //OSSClient client = new OSSClient(OSS_ENDPOINT, ACCESS_ID, ACCESS_KEY, conf); try { ensureBucket(client, BUCKET_NAME); setBucketPublicReadable(client, BUCKET_NAME); System.out.println("正在上传..."); uploadFile(client, BUCKET_NAME, Objectkey, uploadFilePath); System.out.println("正在下载..."); downloadFile(client, BUCKET_NAME, Objectkey, downloadFilePath); }catch(Exception e){ e.printStackTrace(); } finally { deleteBucket(client, BUCKET_NAME); } } /** * 创建Bucket * * @param client OSSClient对象 * @param bucketName BUCKET名 * @throws OSSException * @throws ClientException */ public static void ensureBucket(OSSClient client, String bucketName)throws OSSException, ClientException{ try{ client.createBucket(bucketName); }catch(ServiceException e){ if(!OSSErrorCode.BUCKES_ALREADY_EXISTS.equals(e.getErrorCode())){ throw e; } } } /** * 删除一个Bucket和其中的Objects * * @param client OSSClient对象 * @param bucketName Bucket名 * @throws OSSException * @throws ClientException */ private static void deleteBucket(OSSClient client, String bucketName)throws OSSException, ClientException{ ObjectListing ObjectListing = client.listObjects(bucketName); List<OSSObjectSummary> listDeletes = ObjectListing.getObjectSummaries(); for(int i = 0; i < listDeletes.size(); i++){ String objectName = listDeletes.get(i).getKey(); System.out.println("objectName = " + objectName); //如果不为空,先删除bucket下的文件 client.deleteObject(bucketName, objectName); } client.deleteBucket(bucketName); } /** * 把Bucket设置成所有人可读 * * @param client OSSClient对象 * @param bucketName Bucket名 * @throws OSSException * @throws ClientException */ private static void setBucketPublicReadable(OSSClient client, String bucketName)throws OSSException, ClientException{ //创建bucket client.createBucket(bucketName); //设置bucket的访问权限, public-read-write权限 client.setBucketAcl(bucketName, CannedAccessControlList.PublicRead); } /** * 上传文件 * * @param client OSSClient对象 * @param bucketName Bucket名 * @param Objectkey 上传到OSS起的名 * @param filename 本地文件名 * @throws OSSException * @throws ClientException * @throws FileNotFoundException */ private static void uploadFile(OSSClient client, String bucketName, String Objectkey, String filename) throws OSSException, ClientException, FileNotFoundException{ File file = new File(filename); ObjectMetadata objectMeta = new ObjectMetadata(); objectMeta.setContentLength(file.length()); //判断上传类型,多的可根据自己需求来判定 if (filename.endsWith("xml")) { objectMeta.setContentType("text/xml"); } else if (filename.endsWith("jpg")) { objectMeta.setContentType("image/jpeg"); } else if (filename.endsWith("png")) { objectMeta.setContentType("image/png"); } InputStream input = new FileInputStream(file); client.putObject(bucketName, Objectkey, input, objectMeta); } /** * 下载文件 * * @param client OSSClient对象 * @param bucketName Bucket名 * @param Objectkey 上传到OSS起的名 * @param filename 文件下载到本地保存的路径 * @throws OSSException * @throws ClientException */ private static void downloadFile(OSSClient client, String bucketName, String Objectkey, String filename) throws OSSException, ClientException { client.getObject(new GetObjectRequest(bucketName, Objectkey), new File(filename)); } }
