路由

视图的路由会优先。
要注意，如果你
删除
了一个访问过的视图，这种方法就会出现问题。这个视图将被添加到
autoViews
对象中，因此即使它已经被
删除
，后续的请求也会试图渲染它，这样就出错了。
不过，这个问题是可以解决的，只要使用
try/catch
块把渲染的代码包装起来
，当发现错误
时把视图从
autoViews
中移除即可。我把这个功能增强留作读者的练习。

路由是项目的重要组成部分，而路由处理函数可能的组织方式很多，比在这里概括的要多
得多，所以你大可放心地试验，并找出一种适合你以及你的项目的技术。
我鼓励你优先
采用那些既清晰又易于追踪的技术。在外部世界（客户端，通常是浏览器）看来，路由就
像是一张地图，导向响应它的服务器端代码。如果地图错综复杂，就很难追踪应用的信息
流，对开发和调试都将是障碍。
