Base64.decode介绍

[英]Low-level access to decoding ASCII characters in the form of a byte array. Ignores GUNZIP option, if it's set. This is not generally a recommended method, although it is used internally as part of the decoding process. Special case: if len = 0, an empty array is returned. Still, if you need more speed and reduced memory footprint (and aren't gzipping), consider this method.
[中]对字节数组形式的ASCII字符进行解码的低级访问。忽略GUNZIP选项（如果已设置）。这通常不是推荐的方法，尽管它在内部用作解码过程的一部分。特殊情况：如果len=0，则返回空数组。不过，如果你需要更多的速度和减少内存占用（而不是GZIPIP），请考虑这个方法。
