Issue description
Bucket tags cannot start with acs.
Causes
You called the PutBucketTags operation to configure tags for a bucket and the value of the Key child node whose name starts with acs is contained in the request body in the XML format. However, you cannot call the PutBucketTags operation to configure tags whose names contain the acs prefix.
Invalid examples
For example, you initiate a request by running the following command:
PUT /?tagging
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Tue, 20 Dec 2018 11:49:13 GMT
Authorization: OSS qn6q**************:77Dv****************
</Tagging>
<TagSet>
<Tag>
<Key>acs:abc</Key>
<Value>test</Value>
<Tag>
</TagSet>
</Tagging>In the preceding command, the value of the Key child node of the Tag node in the request body in the XML format starts with acs, which does not meet the requirements of the PutBucketTags operation. In this case, an error is reported.
Solutions
Make sure that the XML request body conforms to the specifications and contains a Tag node that meets the requirements of the PutBucketTags operation. You can refer to the following example.
PUT /?tagging
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
