The value of the AccessKeyId field in the signature request is invalid.

Causes

You initiated a signature request in which the AccessKeyId field in the Authorization header has an invalid value.

Examples

The following code provides an example of a signature request in which the value of the AccessKeyId field in the Authorization header is invalid. For example, \t is included in the value of the AccessKeyId field.

Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Authorization: OSS  qn6qrrqxo2\t:UNQDb7GapEgJkcde6OhZ9J*****

Solutions

Calculate the value of the Authorization field as follows:

Authorization = "OSS " + AccessKeyId + ":" + Signature
Signature = base64(hmac-sha1(AccessKeySecret,
            VERB + "\n"
            + Content-MD5 + "\n" 
            + Content-Type + "\n" 
            + Date + "\n" 
            + CanonicalizedOSSHeaders
            + CanonicalizedResource))
