Question

我正在使用visual studio 2015 rc的Apache cordova模板和离子框架开发跨平台移动应用程序.App的主要功能是将图像从相机上传到远程主机。为此，我在角度控制器中使用文件传输插件，在服务器端使用RestApi（ASP.net webapi）。

但在测试时不断给我这个错误。

例外：

错误： { ＆＃34;代码＆＃34;：1，＆＃34;源＆＃34;：＆＃34; API /文件上传/ uploadfile＆＃34;＆＃34;目标＆＃34;：＆＃34; API /文件上传/ uploadfile＆＃34;＆＃34; HTTP_STATUS＆＃34;：空，＆＃34;主体＆＃34;：空，＆＃34;例外＆＃34; {＆＃34;描述＆＃34;：访问被拒绝＆＃34; ...}

这是我的控制器代码

.controller("ImageUploadCtrl", function($scope, $cordovaFileTransfer) {

    $scope.upload = function() {
        var options = {
            fileKey: "file",
            fileName: "image.jpg",
            chunkedMode: false,
            mimeType: "image/jpeg"
            uploadOptions.httpMethod = "POST";
                uploadOptions.headers = {
                    Connection:"close"
                };
        };
        $cordovaFileTransfer.upload("api/fileupload/uploadfile", "/images/image.jpg", options).then(function (result) {
            console.log("SUCCESS: " + JSON.stringify(result.response));
        }, function (err) {
            console.log("ERROR: " + JSON.stringify(err));
        }, function (progress) {
            // constant progress updates
        });
    }

})

这是我的Api代码

 public void UploadFile()
        {
            if (HttpContext.Current.Request.Files.AllKeys.Any())
            {
                // Get the uploaded image from the Files collection
                var httpPostedFile = HttpContext.Current.Request.Files["file"];

                if (httpPostedFile != null)
                {
                    // Validate the uploaded image(optional)

                    // Get the complete file path
                    var fileSavePath = Path.Combine(HttpContext.Current.Server.MapPath("~/UploadedFiles"), httpPostedFile.FileName);

                    // Save the uploaded file to "UploadedFiles" folder
                    httpPostedFile.SaveAs(fileSavePath);
                }
            }
        }

需要帮助。欢迎提出任何建议。此致

我为公司构建的应用程序有同样的问题，我们无法让文件加载器工作，我们做的是我们刚刚将图像作为base64字符串发布到我们的服务器。然后，您可以简单地从数据库中提取字符串并将其显示在div中。我们使用NgCordova相机，然后只传入takePhoto功能的数据。在android（而不是ios）设备上，您可以使用lz-string.js压缩字符串。同样在Ios上我们必须制作图像png。如果您的应用只需要处理上传图片，这是一种简单易用的方法。

$scope.takePhoto = function () {
            $ionicScrollDelegate.scrollTop();
            console.log('fired camera');
            $scope.uploadList = false;
            $ionicPlatform.ready(function() {
                var options = {
                    quality: 100,
                    destinationType: Camera.DestinationType.DATA_URL,
                    sourceType: Camera.PictureSourceType.CAMERA,
                    allowEdit: false,
                    encodingType: Camera.EncodingType.PNG,
                    targetWidth: 800,
                    targetHeight: 1100,
                    popoverOptions: CameraPopoverOptions,
                    saveToPhotoAlbum: false
                };
                $cordovaCamera.getPicture(options).then(function (imageData) {
                    $ionicLoading.show({
                        template: 'Processing Image',
                        duration: 2000
                    });
                    $scope.image = "data:image/png;base64," + imageData;
                    if (ionic.Platform.isAndroid() === true) {
                        $scope.Data.Image = LZString.compressToUTF16($scope.image);
                        $scope.Data.isCompressed = 1;
                    } else {
                        $scope.Data.Image = $scope.image;
                        $scope.Data.isCompressed = 0;
                    }
                    if ($scope.tutorial) {
                        $scope.showAlert("Instructions: Step 3", '<div class="center">Now that you have taken a photo of the POD form, you must upload it to the server. Press the upload doc button in the bottom right of the screen.</div>');
                    }
                    $scope.on('')
                }, function (err) {
                    console.log(err);
                });
            }, false);
        };

 $scope.UploadDoc = function () {
            var req = {
                method: 'POST',
                url: ffService.baseUrlAuth + 'cc/upload',
                headers: {
                    'x-access-token': ffService.token
                },
                data: $scope.Data
            };
            if ($scope.Data.Image === null || $scope.Data.Value === '') {
                $scope.showAlert("Uh Oh!", '<div class="center">Please take a photo of your document before attempting an upload.</div>');
            } else {
                $http(req).success(function (data, status, headers, config) {
                    localStorage.setItem('tutorial', false);
                    $scope.tutorial = false;
                    $scope.getUploads($scope.PODOrder.OrderNo);
                    $scope.showAlert("Success!", '<div class="center">Your Document has been successfully uploaded!</div>');
                    $scope.uploadList = true;
                }).error(function (data, status, headers, config) {
                    $rootScope.$broadcast('loading:hide');
                    $scope.showAlert("Something went wrong!", '<div class="center">Please make sure you have an internet connection and try again.</div>');
                }).then(function(data, status, headers, config){
                    $scope.Data.Image = null;
                });
            }
        };

最后这个简单的解决方案对我有用。

<强>更新在App控制器和Webapi控制器中更改代码之后每件像魅力和图像一样的东西都是通过API开始在服务器上保存的。

更改代码 我在App控制器选项中添加这些行：

 uploadOptions.httpMethod = "POST";
                    uploadOptions.headers = {
                        Connection:"close"
                    };

并在WebApi Controller中更改此行

var httpPostedFile = HttpContext.Current.Request.Files["file"];

我还在API中启用了CORS。
