Review Comment:
> What's the difference of `CNAME` compared to `path-style`?
For path style, the bucket name will appear in the URL path, i.e.
https://oss-$region.aliyuncs.com/mybucket/objectname. However, this is normally
forbidden. But for some historical reasons, some buckets are allowed to be
accessed using this method.
For cname, the user should bind a bucket to a custom domain and point the
domain to official endpoints using CNAME records. For example, if the user
binds a bucket named `mybucket` to a domain `storage.foo.com` and sets up a
CNAME record to point `storage.foo.com` to an official endpoint (e.g.
`oss-us-east-1.aliyuncs.com`), then no bucket name will be needed to appear
when using this domain to access objects. The URL is just
https://storage.foo.com/objectname.
Technically, this is all about the `Host` header in the request. If a custom
domain is not bound to a bucket in OSS, the access will be denied.
