本专栏为【底层库】,主要介绍编程过程中 通用函数。我们将这些通用固化的源码,进行重写、封装、拓展,再进行单元测试、集成测试、beta测试,最终形成通用化模板,这里我们称为“底层库”。
作为研发人员的你,并不需要花大量时间,研究“底层库”的含义,及“底层库”的实现方法。你只需要几行调用代码,就可以解决项目上碰到的难题。而底层库使用方法,本专栏均有详细介绍,也有项目应用场景。
底层库已实现功能:MySQL脚本构建器、MySQL数据库访问操作、参数配置文件读写、加解密算法、日志记录、HTTP通信、Socket通信、API前后端交互、邮件发送、文件操作、配置参数存储、Excel导入导出、CSV和DataTable转换、压缩解压、自动编号、Session操作等。
本专栏会持续更新,不断优化【底层库】,大家有任何问题,可以私信我。本专栏之间关联性较强(我会使用到某些底层库,某些文章可能忽略介绍),如果您对本专栏感兴趣,欢迎关注,我将带你用最简洁的代码,实现最复杂的功能。
