自定义路由提供程序不是功能时 [英] Custom Route Provider when is not a function

问题描述

这是从今天早上开始的问题的更新版本.

This is an updated version of a question from this morning.

我有两个独立的模块，管理员"和授权".在授权的提供程序块中，我扩展了 $ routeProvider 以便将相同的路由附加到所有路由定义.

I have two separate modules, 'admin' and 'authorization'. In the provider block of authorization, I extend $routeProvider in order to attach an identical route to all of the route definitions.

首先，这是admin.js:

First, here is admin.js:

angular.module('authorization', [])
    .provider('$appRoute', function () {
        this.$get = function($routeProvider) {
            var universalResolves = {authorize: function($authorization) {
                    return $authorization.authorize();
                }};

            var extendedRouter = angular.extend({}, $routeProvider, {
                when: function(path, route) {
                    route.resolve = (route.resolve) ? route.resolve : {};
                    angular.extend(route.resolve, universalResolves);
                    $routeProvider.when(path, route);
                    return this;
                }
            });

            return new extendedRouter();
        }
    })
    .factory('$authorization', ['$http', '$location', function($http, $location) {

        var $authorization = {};

        $authorization.authorize = function() {

            var path = $location.path();

            return promise = $http.get('/svc/authorize/view?urlPath=' + path).then(function(response) {
                var data = response.data;
                if (response.data.result === 'NOT_AUTHORIZED') {
                    throw "NOT_AUTHORIZED";
                }

                return data;
            });

        };

        return $authorization;
    }]);

接下来，我的管理模块:

Next, my admin module:

angular.module('admin', ['ngRoute', 'ngSanitize', 'ngCsv'
        , 'authorization'
    ])

    .controller('mainCtrl', function() {

    })
    .config(['$routeProvider', '$appRouteProvider', function($routeProvider, $appRouteProvider) {

        // old definition that needs to be changed to $appRouteProvider
        $routeProvider.when('/login', {
            templateUrl: '/login/auth.html',
            controller: 'loginCtrl'
        });

        $appRouteProvider.when('/page', {
            templateUrl: 'page.tmpl.html',
            controller: 'pageCtrl'
        });

不幸的是，我收到以下错误:

Unfortunately, I get the following error:

Error: [$injector:modulerr] Failed to instantiate module app due to:

因此它看到了$ appRouteProvider，但只看到了 this.$ get()方法.有人可以帮忙吗?

So it sees the $appRouteProvider, but only the this.$get() method. Can anyone help?

推荐答案

仅就该错误而言， $ appRoute 提供程序不会在其自身上公开任何方法(其他方法除外 $ get ).因此，它是一个空的api配置提供程序对象.

Just regarding the error, the $appRoute provider is not exposing any methods on it self (other then $get). So its an empty api config provider object.

在使用基本提供者配方时， $ get 方法用于提供生成服务的功能，以及提供者提供的 this 用于绑定额外的配置功能，以放置 $ get 函数以后可以使用的数据.

When using the base provider recipe, the $get method is used to provide a function to generate the service, and the this from the provider is used to bind extra config functions to put data the $get function can later use.

来自角度提供者文档:

myApp.provider('unicornLauncher', function UnicornLauncherProvider() {
  var useTinfoilShielding = false;

  // provider config api method.
  this.useTinfoilShielding = function(value) {
    useTinfoilShielding = !!value;
  };

  this.$get = ["apiToken", function unicornLauncherFactory(apiToken) {

    // let's assume that the UnicornLauncher constructor was also changed to
    // accept and use the useTinfoilShielding argument
    return new UnicornLauncher(apiToken, useTinfoilShielding);
  }];
});

如果要在提供程序上添加其他方法，则可以使用 this.when = ... 或 Angular.extends(this，....)例如.

If you want to add additional methods on the provider, you can use this.when = ... or Angular.extends(this, ....) for instance.
