Hexo 永久链接优化

使用 Hexo 博客时，访问文章的默认链接看起来十分杂乱，使用 hexo-abbrlink 插件 可以完美解决这一痛点

食用教程

1. 安装插件$
   npm install hexo-abbrlink --save --registry=https://registry.npmmirror.com
   
   
2. 配置链接格式
   打开 Hexo 根目录下的 _config.yml
   修改 permalink 为如下内容：

   permalink: 'posts/:abbrlink/'
   # 或
   # permalink: 'posts/:abbrlink.html'
   

   
   
3. 插件配置
   在当前配置文件中添加如下代码：

   # hexo-abbrlink
   abbrlink:
     alg: crc16 # 支持crc16和crc32算法（默认crc16）
     rep: hex # 支持dec和hex值（默认dec）
     drafts: false # (true)Process draft,(false)Do not process draft. false(default)
     # Generate categories from directory-tree
     # depth: the max_depth of directory-tree you want to generate, should > 0
     auto_category:
       enable: true # true(default)
       depth: # 3(default)
       over_write: false
     auto_title: false # enable auto title, it can auto fill the title by path
     auto_date: false # enable auto date, it can auto fill the date by time today
     force: false # enable force mode,in this mode, the plugin will ignore the cache, and calc the abbrlink for every post even it already had abbrlink.
   

   
   通过配置 alg 和 rep 参数可以改变链接大小，如下：

   #crc16 & hex
   https://example.com/posts/64c8.html
   # crc16 & dec
   https://example.com/posts/67535.html
   # crc32 & hex
   https://example.com/posts/8dff18eb.html
   # crc32 & dec
