篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了HDwiki 源代码 - 互动百科开源相关的知识,希望对你有一定的参考价值。

昨日3.15,在曝光的企业中出现了一家让我好奇的企业(互动百科),一直不敢想百科能独立出来做成一家公司。出于对网站的好奇,今日进入该网站,惊讶的是此公司已经上市(股票代码:835799),在网站的底部看到 “Powered by HDwiki”。进入HDwiki,赫然写着合作用户“移动”、“华为”。。。而且 “免费开源”。故此下载下来看一下 HDwiki 里面的源代码。很简陋的架构,有 MVC 的样子。几分钟看完,虽然谈不上很有吸引力的项目,也在此留一段里面的代码做个脚印。
