【问题标题】：Angular $httpBackend error "No more request expected"Angular $httpBackend 错误“不再需要请求”

【问题描述】：

下面是我的控制器，

function adminController($scope, $http, $location) {
$scope.enabledRights = [];
$http.get('user/rights').success(function(data) {
        $scope.enabledRights = data;

}).error(function() {
        $scope.enabledRights = [];
});
}

angular.module('queueManagerApp')
.controller('adminController',
    ['$scope', '$http', '$location', '$filter', '$window',    adminController]);

下面是我上面控制器的测试用例

'use strict';

describe('Admin controller', function () {
    var $controller;
    var $httpBackend;
    var $scope;
    var testData = {
      query: {
        input: ['XYZ']

      }
    }

beforeEach(module('queueManagerApp' ));

beforeEach(inject(function(_$controller_, _$httpBackend_) {
$controller = _$controller_;
$scope = {};
$httpBackend = _$httpBackend_;
}));

describe('http test ( Get user rights details -1 )', function () {
 it('should fetch user details', function() {
     $httpBackend.when('GET', '/user/rights')
     .respond(testData);

     $controller('adminController',{ $scope: $scope });

     //$scope.isEnabled();
     $httpBackend.flush();
     expect($scope.enabledRights).toEqual(testData.query.input);
 });
});

describe('http test (get User rights - 2 )', function () {
it('should fetch user rights details',inject(function($http) {
    var $scope = {};

    $http.get('/user/rights')
         .success(function(data,status,headers,config) {
             $scope.enabledRights = data;
         }).error(function(data, status,headers,config) {
             $scope.enabledRights = "Error";
         });

    $httpBackend
     .when('http://localhost:9999/user/rights')
     .respond(200, { enabledRights : 'XYZ' });

     $httpBackend.flush();

     expect($scope.enabledRights).toEqual ( { enabledRights : 'XYZ' }    
);   
}));
});  
});

当我运行测试用例时，我遇到了错误，我不知道如何解决这个问题。请建议我解决同样的问题。

【问题讨论】：

您已将其配置为期待'http://localhost:9999/user/rights'，但您只是请求'/user/rights'。 $httpBackend 关于论点的字面意思
stackoverflow.com/questions/20432482/…的可能重复
嗨，斯科特，感谢您的回复。我已更改为localhost:9999/user/rights，但我仍然遇到同样的错误。
也许你需要把期望放在 $http.get 调用之前？

【解决方案1】：

直到您为您模拟的特定 URL 添加请求，直到那时您将收到此错误

你只做了模拟
确保您在代码中执行特定的 URL 调用
如果您正在加载某些文件，例如 readJson 或require("file.json")
