AngularJS + RequireJS -- 未知提供程序，Angular bug

AngularJS + RequireJS -- Unknown Provider, Angular Bug?

本文关键字：程序 Angular bug RequireJS 未知 AngularJS 更新时间：2023-09-26

我收到以下异常"未知提供程序：authSvc"，它源自我的配置.js文件，我将在下面发布。我知道此错误意味着我的authSvc模块尚未注册并且不可用，但是该服务是在我尝试注入之前创建的。有人可以帮我吗？我迷失在这一点上...所以以为我会转向SO。谢谢。

主.js

require.config({
    paths: {
        'angular': 'vendor/angular',
        'domReady': 'vendor/domready',
        'angularRoute': 'vendor/angular-route',
        'angularLocalStorage': 'vendor/angular-local-storage',
        'bootstrapCss': 'vendor/bootstrap-css'
    },
    shim: {
        'angular': {
            exports: 'angular'
        },
        'angularRoute': {
            deps: ['angular']
        },
        'angularLocalStorage': {
            deps: ['angular']
        }
    },
    deps: ['./bootstrap']
});

引导.js

require([
    'angular', 
    'app',
    'services/authSvc',
    'controllers/navCtrl',
    'controllers/landingPageCtrl',
    'controllers/homeCtrl',
    'controllers/loginCtrl',
    'config',
    'routes'
    ], function (angular) {
    'use strict';
    angular.element(document).ready(function () {
        angular.bootstrap(document, ['myApp']);
    });
});

应用.js

define([
    'angular',
     'angularRoute',
     'angularLocalStorage'
 ], function(angular, angularRoute, angularLocalStorage) {
'use strict';
var app = angular.module('myApp', ['ngRoute', 'LocalStorageModule']);
return app;
});

authSvc.js

define(['app'], function(app) {
    app.service('authSvc', function($http, localStorageService) {
        this.setToken = function(token) {
            return localStorageService.set('token', token);
        }
        this.getToken = function() {
            return localStorageService.get('token');
        }
        this.login = function(username, password) {
            return $http.post('/api/login', {username: username, password: password});
        }
    });
    console.log('authSvc registered');
});

配置.js

define(['app'], function(app) {
    'use strict';
    app.config(function($httpProvider, authSvc) {
        $httpProvider.interceptors.push(function($q) {
          return {
           'request': function(config) {
               // same as above
               //config.headers.token = authSvc.getToken();
               return config;
            },
            'response': function(response) {
               // same as above
               return response;
            }
          };
        });
    });
    console.log('config registered');
});

不能在配置块中注入服务。只有提供者。

app
    .factory('yourInterceptor', yourInterceptor)
    .config(configureInterceptor);
function configureInterceptor($httpProvider) {
    $httpProvider.interceptors.push('yourInterceptor');
}
function yourInterceptor(authSvc) {
    return {
        'request': function (config) {
            // same as above
            //config.headers.token = authSvc.getToken();
            return config;
        },
        'response': function (response) {
            // same as above
            return response;
        }
    };
}

编辑：

将注入器

传递给侦听器，并使用注入器获取服务实例

function yourInterceptor($injector) {
    return {
        'request': function (config) {
            var authService = $injector.get('authSvc');

            //config.headers.token = authSvc.getToken();
            return config;
        },
        'response': function (response) {
            // same as above
            return response;
        }
    };
}
