Question

运行我的代码时出现控制台错误的空白屏幕：

获取http://localhost/templates/home.html 404（未找到）

导致黑屏。代码将运行到灯服务器（localhost）。

好的，让我们看看

这就是你的HTML应该是什么样子

<html ng-app="ionicApp">
  <head>
    //links and stuff
  </head>

  <body>

    <ion-nav-view></ion-nav-view>

    <script id="templates/home.html" type="text/ng-template">
      <ion-side-menus enable-menu-with-back-views="false">
        ...
      </ion-side-menus>
    </script>

    <script id="templates/tester.html" type="text/ng-template">
      <ion-view view-title="TESTER">
        <ion-content>
          ...
        </ion-content>
      </ion-view>
    </script>
  </body>
</html>

这里是Angular部分

angular.module('ionicApp', ['ionic'])

.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider

  .state('home', {
    url: "/home",
    abstract: true,
    templateUrl: "templates/home.html",
    controller: 'TestMenuCtrl'
  })

  .state('home.tester', {
    url: "/tester",
    views: {
      'menuContent': {
        templateUrl: "templates/tester.html",
        controller: 'TesterCtrl'
      }
    }
  });
  // if none of the above states are matched, use this as the fallback
  $urlRouterProvider.otherwise('/home/tester');
})

.controller('TestMenuCtrl', function($scope, $ionicModal, $timeout) {
  // Form data for the login modal
  $scope.loginData = {};

})

.controller('TesterCtrl', function($scope) {
  $scope.oneAndtwo = [
    { title: 'one', id: 1 },
    { title: 'two', id: 2 },
    { title: 'three', id: 3 },
    { title: 'four', id: 4 },
    { title: 'five', id: 5 },
    { title: 'six', id: 6 }
  ];
});

这里有一个工作示例http://jsbin.com/diliru/1/edit?html,js,output

请记住在您的终端中执行ionic serve，请注意这一点：<ion-nav-view name="menuContent"></ion-nav-view>应与您应放在此处的名称相同

  .state('home.tester', {
    url: "/tester",
    views: {
      'menuContent': {
        templateUrl: "templates/tester.html",
        controller: 'TesterCtrl'
      }
    }
  });

记得提到你的依赖。

我不知道还有什么。请告诉我如果我可以提供帮助。

Ionic有自己的服务器来测试您的应用程序。 AFIK，它不是作为普通网站/服务器运行的。作为服务器运行只是他们为更快速地构建应用程序而提供的工具

所以要运行应用程序，

cd to your app folder

run ionic serve

默认情况下

it should start at localhost:8100

详细了解getting started

Answer 3

您可以查看您正在使用的Cordova版本。

cordova -v

如果版本为＆gt; 4.3，请尝试添加白名单插件

ionic plugin add cordova-plugin-whitelist

新的cordova阻止了http请求，当应用程序尝试发出http请求时会出现此错误。

<access origin="*" />

将访问源添加到 config.xml 文件中。

这应该可以解决您的问题
