群晖 Download Station BT 种子下载 自动添加trackerlist

群晖的DownloadStation（简称DS）不支持订阅trackerlist的功能，trackerlist可以让ds去连接更多的种子服务器，让下载速度加快很多；

虽然ds本身不支持订阅trackerlist，但是可以手动向每个下载的任务添加tracker列表，如下图

trackerlist可以从github上公开的仓库获取，也可以找其他的tracker列表，比较有名的trackerlist是这个仓库 https://ngosang.github.io/trackerslist/， 该仓库会定时更新最新的trackerlist。

如果之前看过我的另一篇文章的话，就知道我找到了个万能api可以操作群晖上的任意功能

所以基于这个万能api，我写了个脚本来用于自动向ds的下载任务添加trackerlist，

脚本的配置方法和上面的文章一样，配置一个1分钟的定时任务自动执行，

该脚本就会自动检测ds的下载任务，并且添加trackerlist，这样去下载东西就不用手动添加了
