未知提供者：toasterProvider <- toaster <- RugHttpInterceptor <- $http <- ng1UIRouter

Question

如果我的应用程序在 responseError 代码中捕获到 http 错误，我正在使用拦截器显示 toast 消息。我正在使用 AngularJS 拦截器。这是一个 MEAN.JS 应用程序。

拦截器代码

angular.module('rugCoPro')

.factory('RugHttpInterceptor', ['$q', 'Session', '$state', 'toaster',
function($q, session, $state, toaster) {

    return {        
        'request': function(config) {
            console.log("inside the request."); 
            return config;
        },       

        // Optional method        
        'response': function(response) {
            // do something on response success
            console.log('inside of response');

            return response;
        },

        // optional method 
        'responseError': function(rejection) {
            // Here you can do something in response error, like handle errors, present error messages etc.
            if(rejection.status === 401){
                console.log( "inside the response error : "+ rejection.status);
                $state.go('auth');
            }

            // console.log("inside the response error " + rejection.status);
            return $q.reject(rejection);
        }
    };
}]);

错误：

我正在尝试找出解决方案，但几个小时后就卡住了...

app.js

angular.module('rugCoPro', [
    'ngMaterial',
    'ngMdIcons',
    'ui.router',
    'e3-core-ui.services', 
    'e3-core-ui.utils'  
])

.config(['$stateProvider', '$routeProvider','$httpProvider','$mdThemingProvider', '$mdIconProvider', function($stateProvider, $routeProvider, $httpProvider, $mdThemingProvider, $mdIconProvider) { 

        //rug interceptor code
    $httpProvider.interceptors.push('RugHttpInterceptor');
...
}

脚本和css 使用 npm install 并添加 gruntfile.js

"node_modules/angularjs-toaster/toaster.css",
"node_modules/angularjs-toaster/toaster.js",

Answer 1

通常这是因为它没有包含在您的.html.

确保已加载，在 angular.js 加载后：

<script src="https://cdnjs.cloudflare.com/ajax/libs/angularjs-toaster/1.1.0/toaster.min.js"></script>

Answer 2

您的主应用程序缺少 angularjs-toaster 模块：

angular.module('rugCoPro', [
    'ngMaterial',
    'ngMdIcons',
    'ui.router',
    'toaster', // This was missing from your code
    'e3-core-ui.services', 
    'e3-core-ui.utils'  
]);

您可以从 angularjs-toaster README 查看示例：

// Display an info toast with no title
angular.module('main', ['toaster', 'ngAnimate'])
  .controller('myController', function($scope, toaster) {
    $scope.pop = function(){
      toaster.pop('success', "title", "text");
    };
  });

您还需要在主模板 (index.html) 中包含 angularjs-toaster 模块。这是文档中的示例：

<script src="https://cdnjs.cloudflare.com/ajax/libs/angularjs-toaster/1.1.0/toaster.min.js"></script>
