Problem description

Anonymous access is not supported for the operation.

Causes

No identity information is provided in requests that require identity authentication, such as PutBucket and DescribeRegions.

Examples

For example, you initiate the following request:

GET /?regions HTTP/1.1
Host: oss-cn-hangzhou.aliyuncs.com
Date: Fri, 20 Aug 2021 06:38:30 GMT

The error is returned for the DescribeRegions request because the Authorization request header is not included in the request.

Solutions

We recommend that you use OSS SDK to initiate a request and specify the correct identity information such as the AccessKey pair. For more information, see Overview.

If you want to construct a request, include the Authorization header in the request headers or URL parameters. The following sample code provides a sample request:

GET /?regions HTTP/1.1
Host: oss-cn-hangzhou.aliyuncs.com
Date: Fri, 20 Aug 2021 06:38:30 GMT
Authorization: SignatureValue

For more information, see Include signatures in the Authorization header and Add signatures to URLs.
