从1开始计数将保证简短的唯一URL./1，/2，/3 ...等

Counting up from 1 will guarantee short, unique URLS. /1, /2, /3 ... etc.

在字母表中添加大写和小写字母将提供与问题中类似的URL.而且您只是以62为基础，而不是以10为基础.

Adding uppercase and lowercase letters to your alphabet will give URLs like those in your question. And you're just counting in base-62 instead of base-10.

现在唯一的问题是URL连续出现.要解决此问题，请在此处阅读我对这个问题的回答:

Now the only problem is that the URLs come consecutively. To fix that, read my answer to this question here:

地图将整数范围增加到最大为26位的六位数字，但出乎意料地

基本上，该方法是简单地在递增的值中交换位以给出随机性，同时保持确定性并确保您没有任何冲突.

Basically the approach is to simply swap bits around in the incrementing value to give the appearance of randomness while maintaining determinism and guaranteeing that you don't have any collisions.
