* BASE64编码规则:将一组连续的字节数据按6个bit位进行分组,然后对每组数据用
* 一个ASICC字符来表示,6个bit位最多能表示2的6次方即64个数值,这64个ASICC字符
* 就是:"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/",
* 其中每个字符表示的数值就是该字符在上面的排列中对应的索引号,
* BASE64编码要求在对字节数据按每6个bit位进行分组时,如果不够6位则补"0",
* 另一条规定就是编码后的结果长度必须是4的整数倍,否则补"=".
-* BASE64 encoding rules: a group of consecutive bytes of data bit by 6-bit group, and then for each data character* A ASICC expressed as six bit digital up to that 2 of the 6-th power or 64 value, this 64* is ASICC characters: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/,* in which each character is expressed by the numerical characters in the above with the corresponding index number,* BASE64 encoded byte data requested in each six bit-bit group, if not 6 then fill 0 ,* another requirement is the result of the length of encoding must be integer multiple of 4, or else fill =.
