Object Storage Service:0002-00000070

Problem description

The expiration time in the URL signature is invalid.

Causes

You use the URL signature method to initiate a request. However, the values of the Expires or x-oss-expires field in the URL is invalid.

Examples

• Use the V1 signature to initiate a request

  If you use the V1 signature to initiate a request, the Expires field is used to specify the expiration time of the URL. The following sample code provides an example of invalid value of the Expires field:

  GET /test.txt?OSSAccessKeyId=nz2p****&Expires=abc&Signature=vjbyPxybdZaNmGa%2ByT272YEAiv**** HTTP/1.0
  Date: Tue, 20 Dec 2022 08:48:18 GMT
  Host: oss-example.oss-cn-hangzhou.aliyuncs.com

• Use the V2 signature to initiate a request

  If you use the V2 signature to initiate a request, the x-oss-expires field is used to specify the expiration time of the URL. The following sample code provides an example of invalid value of the x-oss-expires field:

  GET /test.txt?x-oss-signature-version=OSS2&x-oss-expires=abc&x-oss-signature=abc***&x-oss-access-key-id=asfd*** HTTP/1.0
  Date: Tue, 20 Dec 2022 08:48:18 GMT
  Host: oss-example.oss-cn-hangzhou.aliyuncs.com

The expiration time of the URL is a UNIX timestamp, which is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. If the time when Object Storage Service (OSS) receives the request that contains the URL is later than the value of the Expires or x-oss-expires parameter that is included in the signature, a request timeout error is returned.

Solutions

Make sure that the Expires or x-oss-expires field is included in the URL and a correct value is specified for the field. For example, if the current time is 1141889060 and you want to create a URL that is valid within 60 seconds, you must set the Expires parameter to 1141889120. The following code provides an example of a request that uses the V1 signature:

GET /test.txt?OSSAccessKeyId=nz2p****&Expires=1141889120&Signature=vjbyPxybdZaNmGa%2ByT272YEAiv**** HTTP/1.0
Date: Tue, 20 Dec 2022 08:48:18 GMT
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
