Why base64.DecodeString and base64.Decoder behavior different?

[Googol Lee]

Code is here: http://play.golang.org/p/bl8rUPBEmu

Content in str can be decoded by base64.StdEncoding.DecodeString, but using base64.Decoder will raise error "illegal base64 data at input byte 210". How to make base64.Decoder work?
