javascript - 如何将照片从图库复制到数据目录？

Question

我正在尝试将文件从照片库复制到 Android 5.0 设备上的 dataDirectory。 不幸的是，Cordova 相机插件以如下格式返回路径:content://media/external/images/media/8793

 var options = {
                quality: 50,
                destinationType: Camera.DestinationType.FILE_URI,
                sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
                saveToPhotoAlbum: false
            };

            return $cordovaCamera.getPicture(options).then(function (result) {
                return handlePictureResult(result);
            })

$cordovaFile.copyFile('content://media/external/images/media/8793', null, cordova.file.dataDirectory, newFileName) 根本不起作用。

关于如何将文件从图库(内容为://)复制到 cordova.file.dataDirectory 有什么想法吗？

这是你应该如何处理它(使用 fileTransfer plugin 而不是 file one ):

app.controller(
    'MainController',
    [
        '$scope', '$cordovaCamera', '$cordovaFileTransfer',
        function($scope, $cordovaCamera, $cordovaFileTransfer)
        {
            $scope.images = { imageUri: '' };

            $scope.getImage = function()
            {
                var options = {
                    quality: 50,
                    destinationType: Camera.DestinationType.FILE_URI,
                    sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
                    saveToPhotoAlbum: false
                };

                $cordovaCamera.getPicture(options).then(
                    function(fileUri)
                    {
                        console.log(fileUri);

                        $cordovaFileTransfer.download(fileUri, cordova.file.dataDirectory + 'my-image.jpg', {}, true).then(
                            function(fileEntry)
                            {
                                $scope.images.imageUri = fileEntry.nativeURL;
                            },
                            function (error)
                            {
                                console.log(error);
                            }
                        );
                    },
                    function(error)
                    {
                        console.log(error);
                    }
                );
            }
        }
    ]
);

还有 HTML(以防万一):

<section ng-controller="MainController">
    <img ng-src="{{ images.imageUri }}">
    <button ng-click="getImage()">GET IMAGE</button>
</section>
