hexo-abbrlink插件功能:
全自动生成惟一的不带中文的博客链接

原理:
标题+时间进行md5而后再转base64,保存在front-matter中。

npm install hexo-abbrlink --save

permalink: posts/:abbrlink.html
#abbrlink
abbrink:
alg: crc32
rep: dec

链接是修改了,但是图片不能成功显示。
后来发现是与hexo-asset-image不能适配的问题,hexo-abbrlink使用后导致图片路径变化,所以不能成功识别图片。
所以需要修改下面的文件:\node_modules\hexo-asset-image\index.js

  1. 在源码的12行附近var link = data.permalink;这一行的下面,添加一行var abbrlink = data.abbrlink(意思是定义一个变量abbrlink)
  2. 在44行附近,源码的$(this).attr('src', config.root + link + src);这一行,修改 为下面一行:
    $(this).attr('src', config.root + 'posts/' + abbrlink + '/' + src); //适配abbrlink(意思是生成的图片链接中,拼接abbrlink)
