简介

短链接(Short Link)是指将一个原始的长 URL(Uniform Resource Locator)通过特定的算法或服务转化为一个更短、易于记忆的 URL。短链接通常只包含几个字符,而原始的长 URL 可能会非常长。

短链接的原理非常简单,通过一个原始链接生成个相对短的链接,然后通过访问短链接跳转到原始链接。

如果更细节一些的话,那就是:

  1. 生成唯一标识符:当用户输入或提交一个长 URL 时,短链接服务会生成一个唯一的标识符或者短码。
  2. 将标识符与长 URL 关联:短链接服务将这个唯一标识符与用户提供的长 URL 关联起来,并将其保存在数据库或者其他持久化存储中。
  3. 创建短链接:将生成的唯一标识符加上短链接服务的域名(例如:http://nurl.ink )作为前缀,构成一个短链接。
  4. 重定向:当用户访问该短链接时,短链接服务接收到请求后会根据唯一标识符查找关联的长 URL,然后将用户重定向到这个长 URL。
  5. 跟踪统计:一些短链接服务还会提供访问统计和分析功能,记录访问量、来源、地理位置等信息。

短链接经常出现在咱们日常生活中,大家总是能在某些活动节日里收到各种营销短信,里边就会出现短链接。帮助企业在营销活动中,识别用户行为、点击率等关键信息监控。

主要作用包括但不限于以下几个方面:

  • 提升用户体验:用户更容易记忆和分享短链接,增强了用户的体验。
  • 节省空间:短链接相对于长 URL 更短,可以节省字符空间,特别是在一些限制字符数的场合,如微博、短信等。
  • 美化:短链接通常更美观、简洁,不会包含一大串字符。
  • 统计和分析:可以追踪短链接的访问情况,了解用户的行为和喜好。

项目质量怎么样?

短链接项目采用 SaaS 方式开发。"SaaS"代表“软件即服务”(Software as a Service),与传统的软件模型不同,SaaS 不需要用户在本地安装和维护软件,而是通过互联网直接访问在线应用程序。

既然是 SaaS 系统,那势必会带来 N 多个问题。在我看来,问题即项目亮点。一起来看下:

  1. 海量并发:可能会面对大量用户同时访问的情况,尤其在高峰期,这会对系统的性能和响应速度提出很高的要求。
  2. 海量存储:可能需要存储大量的用户数据,包括数据库、缓存等,需要足够的存储空间和高效的存储管理方案。
  3. 多租户场景:通常支持多个租户共享同一套系统,需要保证租户间的数据隔离、安全性和性能。
  4. 数据安全性:需要保证用户数据的安全性和隐私,防止未经授权的访问和数据泄露。
  5. 扩展性&可伸缩性:需要具备良好的扩展性,以应对用户数量和业务规模的增长。

项目实现过程中会充分考虑以上问题,最终实现高可用、可扩展、支持海并发以及存储的 SaaS 短链接系统。另外,会额外交付精美前端控制台页面,学生可用于校招、毕设等场景。

可谓是出门面试,必备好项目!

如何学习?

我个人是偏向于通过文档进行学习,在写 12306 铁路购票系统的时候,写了大量的源码、设计以及从零到一的文档。最终呈现给用户的就是,内容接近130篇,文字20万的 12306 文档库。

但是部分用户在学习过程中,更希望能够通过项目视频学习搭配文档的形式学习。大家都知道,咱们这里只要建议合理都会支持。所以我在开始写 SaaS 短链接项目时,结合大家的建议和想法,最终呈现给大家下面的成果。

视频大概在 80 小节上下,课程总时长在 20-30 小时左右。跟着视频目录看下去,绝对能从零到一复刻出支持海量并发、海量存储的 SaaS 短链接系统。

如果要问,那就是项目代码是我从零到一录视频时写的。
