补充一下:数据库里是原生态的md文本,我的问题是存储到数据库之前,对用户输入的md要怎么处理?

回答:

这个,你得注意两点:

1.入库前的数据验证,牢记,所有用户输入的内容都是不可信的。切记!!!

2.目测你要显示在网页这些内容是吧,你不能直接显示吧...你得显示给用户的是MD转换成HTML的格式,才能友好嘛!对吧~

鉴于以上两点:可以去一个网站:https://packagist.org/

搜索markdown。。你会发现好多好多轮子~当然,你得使用composer~什么?你说你没用这个?Why not?

  • 用一个markdown 解析器,页面上边显示markdown格式的边显示已经解析完毕的

  • 存数据库的时候两个都进行保存

  • 需要更新的时候取出保存的markdown

  • 输出成要看的时候直接输出保存的html
