我今天要写我的第一个科多瓦和离子密码。我想拍一段视频却失败了。除了创建一个空白的Ionic项目外，我还做了以下工作：

bower install ngCordova
将<script src="lib/ngCordova/dist/ng-cordova.js"></script>添加到index.html
cordova plugin add org.apache.cordova.media-capture

我的index.html：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title></title>


    <!-- compiled css output -->
    <link href="css/ionic.app.css" rel="stylesheet">

    <!-- ionic/angularjs js -->
    <script src="lib/ionic/js/ionic.bundle.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="lib/ngCordova/dist/ng-cordova.js"></script>
    <script src="cordova.js"></script>

    <!-- your app's js -->
    <script src="js/app.js"></script>
  </head>
  <body ng-app="locoqr" ng-controller="VideoCtrl">

    <ion-pane>
      <ion-header-bar class="bar bar-header bar-calm">
        <h1 class="title">LocoQR</h1>
      </ion-header-bar>
      <ion-content style="padding: 10px">
          <button class="button button-block button-positive icon ion-videocamera" ng-click="onCaptureVideoClick()">
              Capture a video
          </button>
      </ion-content>
    </ion-pane>
  </body>
</html>

和app.js：

angular.module('locoqr', ['ionic', 'ngCordova'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
    // for form inputs)
    if(window.cordova && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
})

.controller('VideoCtrl', function($scope, $ionicPlatform, $cordovaCapture) {
        $scope.onCaptureVideoClick = function() {
            $ionicPlatform.ready(function() {
                var options = { limit: 3, duration: 15 };
                $cordovaCapture.captureVideo(options).then(function(videoData) {
                    console.log('hooray');
                }, function(err) {
                    console.log('sad :(');
                });
            });
        };
});

我甚至还不知道如何正确地调试，但这正是我从亚行logcat获得的：
