Base64.decode介绍

[英]Decodes an Object using the base64 algorithm. This method is provided in order to satisfy the requirements of the Decoder interface, and will throw a DecoderException if the supplied object is not of type byte[].
[中]使用base64算法解码对象。提供此方法是为了满足解码器接口的要求，如果提供的对象不是byte[]类型，则将抛出DecoderException。
