Java-SDK之如何实现上传文件（六）？

简单列举分片上传事件

1. // endpoint以杭州为例，其它region请按实际情况填写
2. String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
3. // 云账号AccessKey有所有API访问权限，建议遵循阿里云安全最佳实践，创建并使用RAM子账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建
4. String accessKeyId = "<yourAccessKeyId>";
5. String accessKeySecret = "<yourAccessKeySecret>";
6. String bucketName = "<yourBucketName>";
8. // 创建OSSClient实例
9. OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
10. // 列举分片上传事件
11. ListMultipartUploadsRequest listMultipartUploadsRequest = new ListMultipartUploadsRequest(bucketName);
12. MultipartUploadListing multipartUploadListing = ossClient.listMultipartUploads(listMultipartUploadsRequest);
13. for (MultipartUpload multipartUpload : multipartUploadListing.getMultipartUploads()) {
14.     // Upload Id
15.     multipartUpload.getUploadId();
16.     // Key
17.     multipartUpload.getKey();
18.     // Date of initiate multipart upload
19.     multipartUpload.getInitiated();
20. }
21. // 关闭client
22. ossClient.shutdown();

提示：

• 默认情况下，如果存储空间中的分片上传事件的数量大于1000，则只会返回1000个文件， 且返回结果中 IsTruncated 为 false，返回 NextKeyMarker 和 NextUploadIdMarker 作为下次读取的起点。
• 如果没有一次性获取所有的上传事件，可以采用分页列举的方式。
