问题是你可能在之前运行的控制器中注入了 $routeParams 或 $route发生了路线变化，例如您的主/主/页面控制器.

The problem is that you probably inject $routeParams or $route in a controller that is run before a route change has occurred, e.g. your main/master/page controller.

如果您将 $routeParams 注入控制器中的特定路由(在定义路由时由 controller 属性指定)，那么它将起作用，否则您***听一下路由服务广播的各种事件.

If you inject $routeParams in a controller for a specific route (specified by the controller property when you define the route), then it will work, otherwise you're probably better of listening to the various events the route service broadcasts.
