This article will explain in detail how to generate short URL Python based on Redis as a sender. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Description

How to convert a long address URL into a short address URL, an ideal solution is to use the generator to generate a unique integer ID (this unique ID corresponds to the long URL), and then convert it to base 62, which is used as a short address URL.

The implementation of the generator uses Redis's incr function incr ('SID') / / 62 characters as the 62-ary symbol 0123456789 abcdefghijknopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ color _ 12345678 converted to RPGS code # python import redisclass ShortenURL: _ alphabet =' 0123456789 abcdefghijknopqrstuvwzABCDEFHJKLMNOPQRSTUVWXYZMST'_ base = len (alphabet) def encode (self Number): string =''while (number > 0): string = self._ alphabet [number% self._base] + string number / / = self._base return string def decode (self String): number = 0 for char in string: number = number * self._base + self._alphabet.index (char) return numbert = ShortenURL () # Redis as ID sender r = redis.StrictRedis (host='127.0.0.1', port=6379, db=0,password='hooyes') if r.exists ('SID')! = 1: r.set (' SID') 12345677) r.incr ('SID') sid = int (r.get (' SID')) # generate short URL If the domain name is 85.sisn = t.encode (sid) shorturl = 'https://85.si/' + snprint (shorturl) # run python redis-short.py through ShortURL SN decoding to the original SIDprint (t.decode (sn)) test can be tested. / / pay attention to the need to have redis to share the practice of generating short URL Python based on Redis as a sender.
