$httpProvider.responseInterceptors 的替代方案

Question

在 AngularJS V1.3 中，$httpProvider.responseInterceptors 被停用了，它的替代方案是什么？

我的拦截器在 Angular JS 1.2 中可以使用，但在版本 1.3 中无法使用。

var angularErrorHandling = angular.module('xx-http-error-handling', []);
angularErrorHandling.config(function ($provide, $httpProvider, $compileProvider) {
    var elementsList = $();

     push function to the responseInterceptors which will intercept 
     the http responses of the whole application
    $httpProvider.responseInterceptors.push(function ($timeout, $q) {
        return function (promise) {
            return promise.then(function (successResponse) {                
                // if there is a successful response on POST, UPDATE or DELETE we display
                // a success message with green background
                if (successResponse.config.method.toUpperCase() == 'GET') {
                    var length = successResponse.data.length;                    
                    if (length == 0)
                    {
                        var countactivetoaster = $('#toast-container').find('.toast').length;
                        if (countactivetoaster == 0) {
                            toastr.warning('No Records Found!', '');
                        }
                    }                    
                    return successResponse;
                }
                else if (successResponse.config.method.toUpperCase() == 'PUT') {                   
                    toastr.success('Data Saved Sucessfully..', '');
                    return successResponse;
                }
                else if (successResponse.config.method.toUpperCase() == 'POST') {                   
                    toastr.success('Data Saved Sucessfully..', '');
                    return successResponse;
                }
            },
            // if the message returns unsuccessful we display the error 
            function (errorResponse) {
                switch (errorResponse.status) {
                    case 400: // if the status is 400 we return the error                           
                        toastr.error('400 error.', '');
                        // if we have found validation error messages we will loop through
                        // and display them
                        if (errorResponse.data.errors.length > 0) {
                            for (var i = 0; i < errorResponse.data.errors.length; i++) {
                                toastr.error('xx-http-error-validation-message', '');
                            }
                        }
                        break;
                    case 401: // if the status is 401 we return access denied                            
                        toastr.error('Wrong email address or password!', '');

                        break;
                    case 403: // if the status is 403 we tell the user that authorization was denied                          
                        toastr.error('You have insufficient privileges to do what you want to do!', '');
                        break;
                    case 500: // if the status is 500 we return an internal server error message                            
                        toastr.error('Error: <br />' +
                            errorResponse.data.exceptionMessage != null && errorResponse.data.exceptionMessage.length > 0 ? errorResponse.data.exceptionMessage : 
                            errorResponse.data.message, '');
                        break;
                    default: // for all other errors we display a default error message                            
                        toastr.error('Error ' + errorResponse.status + ': ' + errorResponse.data.message, '');
                }
                return $q.reject(errorResponse);
            });
        };
    });

    $compileProvider.directive('httpErrorMessages', function () {
        return {
            link: function (scope, element, attrs) {
                elementsList.push($(element));
            }
        };
    });
});

我认为更加干净/更好的是你必须使用新的拦截器语法：

现在，你会发现可以单独处理4种拦截器：请求、请求错误、响应和响应错误。

// register the interceptor as a service
  $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
    return {
      // optional method
      'request': function(config) {
        // do something on success
        return config;
      },

      // optional method
     'requestError': function(rejection) {
        // do something on error
        if (canRecover(rejection)) {
          return responseOrNewPromise
        }
        return $q.reject(rejection);
      },



      // optional method
      'response': function(response) {
        // do something on success
        return response;
      },

      // optional method
     'responseError': function(rejection) {
        // do something on error
        if (canRecover(rejection)) {
          return responseOrNewPromise
        }
        return $q.reject(rejection);
      }
    };
  });

  $httpProvider.interceptors.push('myHttpInterceptor');

我遇到了错误：Uncaught ReferenceError: $provider未定义。 - Vipul

我给了你AngularJS文档的例子..找到/修复你的错误或编辑你的帖子展示新代码。 - Jscti

当我用我的应用程序对象替换$provider时，它对我起作用了。 - Vipul
