在网页中嵌入Base64编码文件
通过这种方法可以将任何文件转换为Base64编码
这里给出在线转换的网站：http://www.motobit.com/util/base64-decoder-encoder.asp
例子：
显示被存储为Base64编码字符串的图片的例子
使用data: URI直接在网页中嵌入.
data: URI定义于IETF标准的RFC 2397
data: URI的基本使用格式如下：
data:[<MIME-type>][;base64|charset=some_charset],<data>
mime-type是嵌入数据的mime类型，比如png图片就是image/png。
如果后面跟base64，说明后面的data是采用base64方式进行编码的。
代码如下：
- <html> ??
- <body> ??
- <img src='data:image/gif;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAkGBwgHBgkIBwgKCgkLDRYPDQwMDRsUFRAWIB0iIiAd ??
