angular.module('starter.controllers', [])

    $scope.data = {};


    $scope.takePicture = function () {

             controller: 'LoginCtrl'
         });

    $urlRouterProvider.otherwise('/login');  
});

问题：

当我点击按钮以使用相机时

我得到以下例外：

 Module 'ngCordova' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

我在上面错过的地方

任何帮助都将不胜感激

谢谢。

摘自：

在index.html文件中包括ng-cordova.js或ng-cordova.min.js 在cordova.js之前和AngularJS/Ionic文件之后（自 ngCordova取决于AngularJS）

简而言之：您的index.html中缺少ngCordova。

是

当您将图像发送到数据库时，图像来自摄像头的base64字符串。因此，您会自动将该字符串发送到数据库。在您的项目中安装cordova插件add org.apache.cordova.camera

var options = {
      quality: 50,
      destinationType: Camera.DestinationType.DATA_URL,
      sourceType: Camera.PictureSourceType.CAMERA,
      allowEdit: true,
      encodingType: Camera.EncodingType.JPEG,
      targetWidth: 100,
      targetHeight: 100,
      popoverOptions: CameraPopoverOptions,
      saveToPhotoAlbum: false,
      correctOrientation:true
    };

    $cordovaCamera.getPicture(options).then(function(imageData) {
      var image = document.getElementById('myImage');
      image.src = "data:image/jpeg;base64," + imageData;
$scope.Base64string="data:image/jpeg;base64," + imageData;
    }, function(err) {
      // error
    });

write this in your controller and base64 string came in $scope.Base64string but when you send this string one problem came that is you have to store this amount of data in the middle **spaces** came so to neglect the one you will write in services
srting Image="data:image/jpeg;base64,/9j/sfgdhbygcecechghchchvfhcghfvhv57egdhbgh.........";  
string imagerty = Image.Replace(" ", "+");

Or

in Angularjs
var str = 'data:image/jpeg;base64,/9j/sfgdhbygcecechghchchvfhcghfvhv57egdhbgh.........';
var replaced = str.split(' ').join('+');

首先，您需要定义ngCordova脚本（beetween-ionic.bundle.js脚本和cordova.js脚本）

此外，您可能需要安装白名单插件并将元数据添加到索引中，因为在某些移动设备中，由于违反centent安全策略权限，该插件无法工作

这将允许您也使用pictureSelection
