总结：共用了HandyJSON的三个用法，分别是
->###
1、SwiftJSON+HandyJSON解析为String .deserializeFrom(json:JSON(result!).description
2、HandyJSON解析为dictionary JSONDeserializer<AlbumsModel>.deserializeFrom(dict: dict)
3、HandyJSON的Array 用法 self.doubanList = (JSONDeserializer<DouBanListModel>
.deserializeModelArrayFrom(json: JSON(arr!).description) as! [DouBanListModel]?)!
->###
