javascript - Angular UI-Router 缩小错误 - 如何将解析语法更改为基于字符串注入(inject)？

Question

我正在使用带有解析函数的 Angular UI-Router，但是当我缩小解析函数时，我的整个应用程序都崩溃了，因为解析函数语法不适合缩小。它需要是基于字符串注入(inject)的概述 here .我只是不确定如何写它。有什么建议吗？

// Resolves
var checkAuthentication = function($q, $location, $rootScope, Users) {
    if ($rootScope.user) return true;
    if (!$rootScope.user) {
        var deferred = $q.defer();
        Users.get(null, function(user) {
            if (!user) {
                window.location = '/';
                return false;
            }
            console.log('User fetched: ', user);
            $rootScope.user = user;
            deferred.resolve();
        }, function() {
            window.location = '/';
            return false;
        });
        return deferred.promise;
    }
};

// Routes
angular.module('Dashboard').config(['$stateProvider', '$urlRouterProvider',
    function($stateProvider, $urlRouterProvider) {
        // For any unmatched url, redirect to '/'
        $urlRouterProvider.otherwise('/dashboard');
        // Now set up the states
        $stateProvider
            .state('dashboard', {
                url: '/dashboard',
                templateUrl: 'views/content/dashboard.html',
                resolve: {
                    checkAuthentication: checkAuthentication
                }
            })

您通常执行此操作的方式是将数组传递给解析:

resolve: {
    welcome: ['$q', function ($q) {
        var def = $q.defer();
        setTimeout(function () {
            def.resolve("Hello World!");
        },500);
        return def.promise;
    }]
}

考虑到这一点，您可以像这样定义您的 var:

var welcome = ['$q', function ($q) {
    var def = $q.defer();
    setTimeout(function () {
        def.resolve("Hello World!");
    },500);
    return def.promise;
}]

但这当然不是真正可重用的，所以在这一点上我建议将其移至服务。
