在Angular中，如何从控制器内部找到"called"控制器的路由？

Question

我知道两条或多条路线可以共享同一个控制器。但是，在控制器上，我想知道是哪条路由"called"而已。为什么？哪条路线将决定我是加载记录列表、通过其 ID 加载一条记录，还是根本不加载任何内容。

我有以下路线配置：

angular.module("app").config(function ($routeProvider) {

    $routeProvider.when("/", {
        templateUrl: "home.html"
    }).when("/records", {
        templateUrl: "records.html",
        controller: "RecordsController"
    }).when("/record/create", {
        templateUrl: "editRecord.html",
        controller: "RecordsController"
    }).when("/template/edit/:id", {
        templateUrl: "editRecord.html",
        controller: "RecordsController"        
    }).otherwise({
        redirectTo: "/"
    });

});

我只想使用一个控制器，所以我有一个：

angular.module("app").controller("RecordsController", function($http, $routeParams){
     /* I know that if $routeParams.id exists, it's probably the
        /record/edit/:id route. But if $routeParams.id is null/undefined,
        I don't know which of /records or /record/create "called"
        this controller. I would like to know which route so I can
        decide to load a list (if /records) or not (for /record/create).
     */
});

除非有一些技巧可以从路由配置中提取，比如 resolve，不知何故？

Answer 1

使用$location.path()

来自 docs：

The $location service parses the URL in the browser address bar (based on window.location) and makes the URL available to your application.

...

Getter and setter methods

// get the current path
$location.path();

在你的控制器中使用

angular.module("app").controller("RecordsController", function($http, $routeParams, $location){
   var path = $location.path();
   // Do something with `path` ...       

});

Answer 2

导入 $locationProvider 并在控制器中检查 $location.path()

if($location.path() == '/record")
