本文整理了Java中org.apache.tomcat.util.codec.binary.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：org.apache.tomcat.util.codec.binary.Base64
类名称：Base64

Base64介绍

[英]Provides Base64 encoding and decoding as defined by RFC 2045.

This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.

The class can be parameterized in the following manner with various constructors:

  • URL-safe mode: Default off.
  • Line length: Default 76. Line length that aren't multiples of 4 will still essentially end up being multiples of 4 in the encoded data.
  • Line separator: Default is CRLF ("\r\n")

Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).

This class is thread-safe.
[中]提供由RFC 2045定义的Base64编码和解码。
此类实现了第6.8节。RFC 2045多用途Internet邮件扩展（MIME）的Base64内容传输编码第一部分：Freed和Borenstein的Internet邮件正文格式。
该类可以通过以下方式使用各种构造函数进行参数化：
*URL安全模式：默认关闭。
*行长度：默认为76。在编码数据中，不是4的倍数的行长度实际上仍然是4的倍数。
*行分隔符：默认为CRLF（“\r\n”）
由于该类直接对字节流而不是字符流进行操作，因此它被硬编码为仅对与较低的127 ASCII图表（ISO-8859-1、Windows-1252、UTF-8等）兼容的字符编码进行编码/解码。
这个类是线程安全的。
