API Description

You can use this API to set lifecycle rules for a bucket, to periodically transit storage classes of objects and delete objects in the bucket.

Method Definition

func (obsClient ObsClient) SetBucketLifecycleConfiguration(input *SetBucketLifecycleConfigurationInput) (output *BaseModel, err error)

Method Definition If a Signed URL Is Used

func (obsClient ObsClient) SetBucketLifecycleConfigurationWithSignedUrl(signedUrl string, actualSignedRequestHeaders http.Header, data io.Reader) (output *BaseModel, err error)

Request Parameter

Returned Result

Sample Code

func main() {
       input := &obs.SetBucketLifecycleConfigurationInput{}
