1. 自定义编码规则

可以用于URL的编码
解码规则可自行补充

扩展：可以每次生成不同的编解码字符映射

找出大量的中文繁体形近字，作为‘编码字符池’
每次使用随机抽取形式，找出的N个不重复字符作为当下编码字符

将这N个字符组成的字符串保存下来，用于生成特定的编解码逻辑

获取当下编码字符串

//获取当下编解码字符串
//将currEncodeStr保存下来，用于生成特定的编解码逻辑
String currEncodeStr = gainCurrEncodeStr();

编码

//将获取的编码字符串传入，生成数组
String[] encodeStrs = gainEncodeStrs(currEncodeStr);
//编码逻辑中的字符，取数组中对应索引的值
URL_COLON = encodeStrs[0];
***
URL_HTTPS = encodeStr[X];

//对特定字符串的加密/编码，逻辑不变

解码使用编码逆逻辑
