本文代码基于Typecho构建，handsome主题测试，其他主题理论上不通用。
基于很受欢迎的handsome主题堆出来一个聚合页。
加入了异步加载机制，并支持缓存，默认2小时。
重要提示：假如以下代码文件在handsome文件夹下，使用缓存时，在handsome文件夹下建立cache目录，总之此文件和cache目录必须在同一个目录下。
第一次刷新获取，所有友链将缓存存储在cache目录下，2小时后自动过期。2小时内刷新页面直接取cache文件显示，2小时后过期重新获取新的xml存储在cache目录。如果需要强制更新，删除cache目录下所有文件并重新刷新页面即可。
本地演示如下：
代码逻辑可以参考WordPress篇，这个和WP不同的地方在于没有加入缓存机制，实时的，但是本地测试挺快。
代码如下：
