使用$ resource调用远程webapi时，angularjs访问被拒绝

我不确定我的Angular应用程序调用WebAPI是否存在CORS问题 . 我的ASP.Net MVC / Angular App1和Web API托管在同一个IIS服务器上 . 例如，App1的url是https://example.com/App1 . Web API网址是http://example.com/wcf_webapi/clinicaluserprofile/api/ . 在MVC视图页面上有一个 <div ng-include=" 'path to an angular view template' "></div> ，它使用$ resource从WebAPI获取数据 . 在Visual Studio 2013 IDE中，当我按F5在我的开发工作站上进行调试时，一切都按预期工作 . 我可以在IE Developer Tools中看到对Web API的调用' Network tab. However, when I publish App1 to that IIS server, the Web API call doesn' . 相反，我在IE Developer Tools Console中看到了 access denied . 我在不同文件夹中的同一个IIS上有另一个MVC / Angular App2，几乎相同的Angular代码 . App2的网址是https://example.com/App2 . 它不会被拒绝访问 . 你能帮我吗？谢谢 .

这是Config.js

/// <reference path="C:\Users\myName\Source\Repos\Apps\App1\Scripts/angular.js" />
(function() {
  'use strict'

  var moduleName = 'configModule';
  angular.module(moduleName, []);

  var apiKeyValuePair = {
    'api': {
      centralAdmin: 'http://example.com/wcf_webapi/CentralAdmin/api/',
      fsr: 'http://example.com/FSRManagement/api/',
      userProfile: 'http://example.com/wcf_webapi/clinicaluserprofile/api/'
    }
  }

  var userKeyValuePair = {
    'userAccount': {
      //this is bootstraped and updated in MVC view page <script> block
      userName: ''
    }
  }

  //populate the constant collection
  angular.forEach(apiKeyValuePair, function(val, key) {
    angular.module(moduleName).constant(key, val);
  });
   
  //populate the value collection
  angular.forEach(userKeyValuePair, function(val, key) {
    angular.module(moduleName).value(key, val);
  });
})();

这是App.js

/// <reference path="C:\Users\myName\Source\Repos\Apps\App1\Scripts/angular.js" />
(function() {
  'use strict'
  var moduleName = 'ufsrAppModule';
  var requiredModules = [
    'configModule',
    'fsrFactoryModule',
    'userFsrFactoryModule',
    'userProfileFactoryModule'
  ]
  var app = angular.module(moduleName, requiredModules);
  //  app.config(
  //    )

})();

这是userProfileFactory.js

/// <reference path="C:\Users\myName\Source\Repos\Apps\App1\Scripts/angular.js" />
/// <reference path="C:\Users\myName\Source\Repos\Apps\App1\Scripts/angular-resource.js" />
/// <reference path="../config.js" />

(function() {
  'use strict';

  var moduleName = 'userProfileFactoryModule';
  var factoryName = 'userProfileFactory';
  var requiredModules = ["ngResource", "configModule"];
  var dependencyInjection = ['$resource', 'api', 'userAccount', internalFunc];

  angular.module(moduleName, requiredModules)
    .factory(factoryName, dependencyInjection);

  function internalFunc($resource, api, userAccount) {
    function getUserProfile() {
      return $resource(api.userProfile + 'user/profile/:NN', {
        NN: '@NN'
      });
    };

    return {
      //usage: userProfileFactory.getUserProfile()
      getUserProfile /*public method*/ : getUserProfile /*internal method above*/
    }
  }
})();
