Windows 8 Phonegap windows 8应用程序，具有摄像头功能，导航。摄像头。getPicture（）回调函数在部署时从不调用

我们使用phonegap制作了一个Win8应用程序。 该应用程序还引用了用于执行某些asyc任务的Windows运行时组件。 该应用程序有一个摄像头功能，在摄像头中调用，拍摄照片，然后在成功回调功能的屏幕上显示照片。直接从visual studio express运行时，一切都可以完美运行。当我们创建应用程序包并使用metro sideloader或powershell部署它时，就会出现问题。从未调用照相机成功回调函数。 调用相机的代码如下所示：

    CameraService = function() {
        var that = {};

        that.invokecamera = function(callback) {
            try {
                GLOBALS.callback = callback;
                if (GLOBALS.Ready) {
                    navigator.camera.getPicture(that.onSuccess, GLOBALS.ThrowException, {
                        quality : 50,
                        saveToPhotoAlbum : true,
                        destinationType : Camera.DestinationType.FILE_URI
                    });
                }
            } catch (err) {
                alert(err);
            } finally {
            }
        }
        that.onSuccess=function(imageURI) {
        GLOBALS.ImagePath = imageURI;
        GLOBALS.callback(imageURI);
    }
        return that;
    }

好的，我解决了这里提到的问题：

要修复此问题，请参见替换的链接

Windows.Storage.StorageFolder.getFolderFromPathAsync(packageId.path).done(function (storageFolder) {

与

在cordova.js文件中。我正在使用cordova 2.4.0

更详细的例子

Windows.Storage.StorageFolder.getFolderFromPathAsync(packageId.path).done(function (storageFolder) {
                                        storageFolder.createFileAsync(tempPhotoFileName, Windows.Storage.CreationCollisionOption.generateUniqueName).done(function (file) {
                                            file.openAsync(Windows.Storage.FileAccessMode.readWrite).done(function (fileStream) {
                                                Windows.Storage.Streams.RandomAccessStream.copyAndCloseAsync(_stream, fileStream).done(function () {
                                                    var _imageUrl = URL.createObjectURL(file);
                                                    successCallback(_imageUrl);
                                                }, function () { errorCallback("Resize picture error."); });
                                            }, function () { errorCallback("Resize picture error."); });
                                        }, function () { errorCallback("Resize picture error."); });
                                    });

变成

var storageFolder = Windows.Storage.ApplicationData.current.localFolder;                                    
storageFolder.createFileAsync(tempPhotoFileName, Windows.Storage.CreationCollisionOption.generateUniqueName).done(function (file) {
                                            file.openAsync(Windows.Storage.FileAccessMode.readWrite).done(function (fileStream) {
                                                Windows.Storage.Streams.RandomAccessStream.copyAndCloseAsync(_stream, fileStream).done(function () {
                                                    var _imageUrl = URL.createObjectURL(file);
                                                    successCallback(_imageUrl);
                                                }, function () { errorCallback("Resize picture error."); });
                                            }, function () { errorCallback("Resize picture error."); });
                                        }, function () { errorCallback("Resize picture error."); });

var storageFolder = Windows.Storage.ApplicationData.current.localFolder;                                    
storageFolder.createFileAsync(tempPhotoFileName, Windows.Storage.CreationCollisionOption.generateUniqueName).done(function (file) {
                                            file.openAsync(Windows.Storage.FileAccessMode.readWrite).done(function (fileStream) {
                                                Windows.Storage.Streams.RandomAccessStream.copyAndCloseAsync(_stream, fileStream).done(function () {
                                                    var _imageUrl = URL.createObjectURL(file);
                                                    successCallback(_imageUrl);
                                                }, function () { errorCallback("Resize picture error."); });
                                            }, function () { errorCallback("Resize picture error."); });
                                        }, function () { errorCallback("Resize picture error."); });
