本文整理了Java中net.i2p.data.Base64类的一些代码示例，展示了Base64类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Base64类的具体详情如下：
包路径：net.i2p.data.Base64
类名称：Base64

Base64介绍

[英]Encodes and decodes to and from Base64 notation.

Change Log:

  • v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.
  • v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input stream where last buffer being read, if not completely full, was not returned.
  • v1.3.4 - Fixed when "improperly padded stream" error was thrown at the wrong time.
  • v1.3.3 - Fixed I/O streams which were totally messed up.

I am placing this code in the Public Domain. Do with it as you will. This software comes with no guarantees or warranties but with plenty of well-wishing instead! Please visit http://iharder.net/xmlizable periodically to check for updates or to contribute improvements.
Modified by jrandom for i2p, using safeEncode / safeDecode to create filesystem and URL safe base64 values (replacing / with ~, and + with -)
[中]对Base64符号进行编码和解码。
更改日志：
*v1。3.6-固定输出流。刷新（），以便重置“位置”。
*v1。3.5-添加了用于打开和关闭换行符的标志。修复了输入流中最后一个被读取的缓冲区（若未完全填满）未返回的错误。
*v1。3.4-修复了在错误时间抛出“未正确填充的流”错误。
*v1。3.3-修复了完全混乱的I/O流。
我将此代码置于公共域中。你想怎么做就怎么做。这个软件没有任何保证或保证，但却有很多美好的愿望！请定期访问http://iharder.net/xmlizable，检查更新或作出改进。
由jrandom针对i2p进行修改，使用safeEncode/safeDecode创建文件系统和URL safe base64值（替换为~，替换为-）
