func (*ObjectService) AbortMultipartUpload 

func (s *ObjectService) AbortMultipartUpload(ctx context.Context, name, uploadID string) (*Response, error)

AbortMultipartUpload 用来实现舍弃一个分块上传并删除已上传的块。当您调用Abort Multipart Upload时， 如果有正在使用这个Upload Parts上传块的请求，则Upload Parts会返回失败。当该UploadID不存在时，会返回404 NoSuchUpload。

建议您及时完成分块上传或者舍弃分块上传，因为已上传但是未终止的块会占用存储空间进而产生存储费用。

func (*ObjectService) CompleteMultipartUpload 

func (s *ObjectService) CompleteMultipartUpload(ctx context.Context, name, uploadID string, opt *CompleteMultipartUploadOptions) (*CompleteMultipartUploadResult, *Response, error)

CompleteMultipartUpload 用来实现完成整个分块上传。当您已经使用Upload Parts上传所有块以后，你可以用该API完成上传。 在使用该API时，您必须在Body中给出每一个块的PartNumber和ETag，用来校验块的准确性。

由于分块上传的合并需要数分钟时间，因而当合并分块开始的时候，COS就立即返回200的状态码，在合并的过程中， COS会周期性的返回空格信息来保持连接活跃，直到合并完成，COS会在Body中返回合并后块的内容。

当上传块小于1 MB的时候，在调用该请求时，会返回400 EntityTooSmall； 当上传块编号不连续的时候，在调用该请求时，会返回400 InvalidPart； 当请求Body中的块信息没有按序号从小到大排列的时候，在调用该请求时，会返回400 InvalidPartOrder； 当UploadId不存在的时候，在调用该请求时，会返回404 NoSuchUpload。

建议您及时完成分块上传或者舍弃分块上传，因为已上传但是未终止的块会占用存储空间进而产生存储费用。
