Issue description

The X-Amz-Expires parameter is missing in the request.

Cause

You initiate a request that uses the Amazon S3-compatible V4 signature. However, the X-Amz-Expires parameter is missing in the request.

Example

The following code provides an example:

GET /test.txt?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=LTAI****************/20221220/us-east-1/s3/aws4_request&X-Amz-Date=20221220T084818Z86400&X-Amz-SignedHeaders=host&X-Amz-Signature=ab2***st HTTP/1.0
Date: Tue, 20 Dec 2022 08:48:18 GMT
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
x-oss-s3-compat: true

The X-Amz-Expires parameter, whose value is a UNIX timestamp, is used to specify the expiration time of the request.

Solution

Make sure that the URL parameters are complete and valid values are specified for the parameters.

GET /test.txt?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=LTAI****************/20221220/us-east-1/s3/aws4_request&X-Amz-Date=20221220T084818Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=ab2s**** HTTP/1.0
Date: Tue, 20 Dec 2022 08:48:18 GMT
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
x-oss-s3-compat: true

We recommend that you use Amazon S3 SDKs to initiate the request. For more information, see Use Amazon S3 SDKs to access OSS.
