博客旧数据迁移

祝福大家中秋快乐！！

在中秋到来之际，终于把以前BO-BLOG的数据全部迁移到这里，其实代码没有多少，但是分析的时间比较多。

之前非常非常喜欢写博客，所以写了很多很多年，但由于一些事情，我停止了博客的更新，不过最近，我又开始将线下写日记改成了线上写博客了。

之前的往事，我是不想再提了。

我以前是Bo-Blog 2.1.1这个版本，为了适配到新的WP，我查看了2边数据库的差别，然后直接采用数据库转存的方式，将Bo-Blog 的数据迁移到了这里。

迁移中，我迁移了附件，图片。但我的WP主题，是有特色图片的，以前 Bo-Blog中并没有这个功能，所以，这部分估计到时候还需要慢慢来添加好看的特色图片。

其中有2个模块，我也完整的迁移过来，第一个是代码，第二个是分类，我按照我需要的，在WP中增加了一个AH代码高亮的插件，然后将以前的代码标签转换成了现在的标签。

图片附件标签同样我也做了转换。

下面就是完整的python迁移代码 [ 因为AH没有PYTHON高亮，我用的其他高亮展示]：
