方法一，复制文件但不修改名称仅修改存储类型
/**
* 设置对象的存储类型
*/
public void setObjectStorageClassWhenCopy() {
// 初始化 Ks3Client，参见“初始化”文档
Ks3Client ks3Client = initKs3Client();
try {
CopyObjectRequest request = new CopyObjectRequest("bucketName", "objectKey", "bucketName", "objectKey");
request.setStorageClass(StorageClass.Standard);
// 发起请求，设置对象的存储类型
CopyResult copyResult = ks3Client.copyObject(request);
System.out.println("ETag: " + copyResult.getETag());
System.out.println("CRC64: " + copyResult.getCrc64Ecma());
System.out.println("Last Modified: " + copyResult.getLastModified());
} catch (Ks3ServiceException e) {
System.out.println("Ks3ServiceException occurred, which means the request was made to KS3, but KS3 returned an error response for some reason.");
System.out.println("Error Message: " + e.getErrorMessage());
System.out.println("Error Code: " + e.getErrorCode());
System.out.println("Request ID: " + e.getRequestId());
} catch (Ks3ClientException e) {
System.out.println("Ks3ClientException occurred, which means the client encountered an internal error while trying to communicate with KS3.");
System.out.println("Error Message: " + e.getMessage());
} finally {
// 关闭 Ks3Client
ks3Client.shutdown();
}
}方法二，使用 putObjectStorageClass 方法（1.4.0 版本及之后）
/**
* 设置对象的存储类型
* 本质上仍是 copy object，与上面的方式相同
* 1.4.0 及之后版本支持
*/
public void putObjectStorageClass() {
// 初始化 Ks3Client，参见“初始化”文档
Ks3Client ks3Client = initKs3Client();
try {
// 发起请求，设置对象的存储类型
CopyResult copyResult = ks3Client.putObjectStorageClass("bucketName", "objectKey", StorageClass.Standard);
System.out.println("ETag: " + copyResult.getETag());
System.out.println("CRC64: " + copyResult.getCrc64Ecma());
System.out.println("Last Modified: " + copyResult.getLastModified());
} catch (Ks3ServiceException e) {
System.out.println("Ks3ServiceException occurred, which means the request was made to KS3, but KS3 returned an error response for some reason.");
System.out.println("Error Message: " + e.getErrorMessage());
System.out.println("Error Code: " + e.getErrorCode());
System.out.println("Request ID: " + e.getRequestId());
} catch (Ks3ClientException e) {
System.out.println("Ks3ClientException occurred, which means the client encountered an internal error while trying to communicate with KS3.");
System.out.println("Error Message: " + e.getMessage());
} finally {
// 关闭 Ks3Client
ks3Client.shutdown();
}
