在Angular中，如何在启动之前从服务器获取引导数据？

A bit of info. I'm working on a single page app, but am attempting to make it just an HTML file, rather than an actual dynamic page that contains all the bootstrap information in it. I'm also hoping to, when the app boots (or perhaps prior to), check to see if the current session is 'logged in', and if not then direct the hash to the 'login'. A bit of info.
