Question

我正在使用nervgh的Angular-File-Upload https://github.com/nervgh/angular-file-upload

当我对preOpKey进行硬编码时，它就像一个魅力。我想要做的是发送preOpKey和文件，以便我可以将文件保存到数据库中的相应记录。

angular-file-upload在API中有一个fileData，我在$scope.OnPreinspectionSubmit()中填充但由于某种原因，我在MVC控制器中找不到SaveFile()的值被称为。

我只需要知道如何将值与我的文件一起传递，然后在我的MVC控制器中访问它。我想在fileData发送它会很方便，但这不是回答我的问题所必需的。

这是我的Angular控制器：

var OperatorPreinspectionControllers = angular.module('OperatorPreinspectionControllers', ['angularFileUpload']);

OperatorPreinspectionControllers.controller('OperatorPreinspectionCtrl', ['$scope', '$http', 'FileUploader',
    function ($scope, $http, FileUploader) {

        $scope.uploader = new FileUploader({
            url: pageBaseUrl + 'image/SaveFile'
        });

        $scope.uploader.filters.push({
            name: 'imageFilter',
            fn: function (item /*{File|FileLikeObject}*/, options) {
                var type = '|' + item.type.slice(item.type.lastIndexOf('/') + 1) + '|';
                return '|jpg|png|jpeg|bmp|gif|pdf|'.indexOf(type) !== -1;
            }
        });

        // Send the form data to the database
        $scope.OnPreinspectionSubmit = function () {
            if (confirm("Are you sure you want to save this information?")) {
                $http.post(pageBaseUrl + 'api/PreInspectionForm', $scope.formInformation).success(function (returnData) {
                    $scope.uploader.formData.push({ preOpKey: returnData });
                    $scope.uploader.uploadAll(); // Upload file
                });
            } else { }
        }
    }
]);

这是我的MVC控制器：

public void SaveFile()
    {
        HttpFileCollectionBase files = Request.Files;
        HttpPostedFileBase uploadedFile = files[0];

        var preOpKey = 123; // ???????

        // Turn the file into bytes
        byte[] data;
        using(Stream inputStream = uploadedFile.InputStream)
        {
            MemoryStream memoryStream = inputStream as MemoryStream;
            if(memoryStream == null)
            {
                memoryStream = new MemoryStream();
                inputStream.CopyTo(memoryStream);
            }
            data = memoryStream.ToArray();
        }

        PreOpManager.SaveImage(preOpKey, data, uploadedFile.FileName, uploadedFile.ContentType);
    }

谢谢，

到目前为止，对我来说完美无缺的解决方案一直是：

$scope.uploader.onBeforeUploadItem = onBeforeUploadItem;

function onBeforeUploadItem(item) {
  item.formData.push({your: 'data'});
  console.log(item);
}
