Problem description

OSS returns a 403 error when you call an API operation signed with a V1 signature.

Causes

OSS no longer supports V1 signatures. For details, see Notice on the Discontinuation of the OSS V1 Signature Algorithm.

Examples

A V1 signature passes OSSAccessKeyId, Expires, and Signature as query parameters in the URL. The following example shows a PutBucketAcl request signed with V1:

PUT /?acl
    &OSSAccessKeyId=nz2p****     # AccessKey ID passed as a query parameter
    &Expires=abc                 # Request expiration timestamp
    &Signature=vjbyPxybdZaNmGa%2ByT272YEAiv****  # V1 signature value
    HTTP/1.1
x-oss-acl: Permission
Host: BucketName.oss-cn-hangzhou.aliyuncs.com
Date: GMT Date

Solutions

Upgrade to V4 signatures. See Upgrade from V1 to V4 signatures for migration instructions.
