Problem Description
The time when a request is initiated to access OSS objects by using a signed URL that contains a V4 signature is not within the validity period of the URL.
Cause
The time when a request is initiated to access OSS objects by using a signed URL that contains a V4 signature is later than the end time of the validity period of the signed URL.
Examples
The start time of the validity period of the signed URL specified by x-oss-date is 20231220T083018Z. The validity period of the signed URL specified by x-oss-expires is 86,400 seconds (one day). As a result, the time when a request is initiated to access OSS objects by using a signed URL that contains a V4 signature cannot be later than 20231221T083018Z. However, the actual time when the request is initiated is 20231222T083018Z.
