AngularJS - 如何从URL获取参数

Question

我试图将参数传递给AngularJS控制器。

AngularJs路线

$routeProvider.when('/post-ads/', {
            templateUrl: "ui/view/post-ads.php",
            controller: "adPostController",
            controllerAs: 'vm'
        })

        $routeProvider.when('/post-ads/:category/:subcategory', {
            templateUrl: "ui/view/ad-details.php",
            controller: "adPostController",
            controllerAs: 'vm'
        })

AdPostController

adPostController.$inject = ['ApiService', '$scope'];
    function adPostController(ApiService, $scope, $routeParams) {
        console.log("im here");
        console.log($routeParams.category, $routeParams.subcategory);
    }

HTML a href

<a href="#/post-ads/automobile/car>click</a>

错误

  

TypeError：无法读取属性＆＃39;类别＆＃39;未定义的

Answer 1

更改为：

adPostController.$inject = ['ApiService', '$scope', '$routeParams'];

Answer 2

我想你必须改变：

adPostController.$inject = ['ApiService', '$scope'];
    function adPostController(ApiService, $scope, $routeParams) {
        console.log("im here");
        console.log($routeParams.category, $routeParams.subcategory);
    }

要：

adPostController.$inject = ['ApiService', '$scope', '$srouteParams'];
    function adPostController(ApiService, $scope, $routeParams) {
        console.log("im here");
        console.log($routeParams.category, $routeParams.subcategory);
    }
