使用 UI 路由器访问从解析函数调用的服务中新状态的 $stateParams [英] Access $stateParams of new state in service called from resolve function with UI Router

问题描述

有没有办法访问 $stateParams 以获取您要从解析函数中调用的服务转换到的状态?使用 ngRoute，您将使用 $route.current.params.正如这个最小的 plunk 显示的那样，该服务只会看到您要离开的状态:

Is there a way to access $stateParams for the state you're transitioning to from a service called in a resolve function? With ngRoute you'd use $route.current.params. As this minimal plunk shows, the service only sees the state you're leaving:

当 $stateParams 直接注入解析函数时，我得到了新的 $stateParams，但这些值仍然落后于服务中的一个路由.

I get the new $stateParams when $stateParams is injected directly into a resolve function, but the values are still behind by one route in the service.

我错过了什么?

推荐答案

你不能将传入的参数注入到服务本身，但是你可以将它们传递给一个函数(或者您也可以将它们分配给服务中的属性).

You can't inject the the incoming parameters into the service itself, but you can pass them to a function in the service (or you could also assign them to a property in the service).

this plunker 展示了如何将它们传递给函数，该函数又将它们存储到服务.使用虚拟"属性不应该受到伤害，但它有点难看.:)

this plunker shows how to pass them to a function, which in turns stores them to a property in the service. Using a "dummy" property shouldn't hurt, but it is a bit ugly. :)

将参数作为解析属性传递给控制器​​，然后将它们从控制器构造函数传递给服务可能更有意义……这就是我要做的.

It might make more sense to pass the parameters to the controller as a resolve property and then hand them out to a service from the controller constructor... that's what I'd do.
