来自角度ng-file-upload的ng-model，用于上传的mongodb文件名

Question

你好，我有一个问题上传照片在平均堆栈由休息api。上传已经工作正常，但我有问题，在我的解决方案中如何传递上传到mongodb的文件名。这是我的上传代码和api我使用两个api的一个表单一个页面desc标题另一个上传它的好决定？还是最好用一个api页面？上传工作文件上传提交表单但在mongodb featuredImage为null。如何使用ng-file-upload将名称传递给mongodb进行上传即可使用ng-model =“pageContent.featuredImage”？

form.html

<textarea ui-tinymce="tinymceOptions"  rows="15" class="form-control" type="text" ng-model="pageContent.content"></textarea>
    <input type="file" ngf-select ng-model="picFile" name="file"
             accept="image/*" ngf-max-size="2MB"
             ngf-model-invalid="errorFile">
    <input type="submit" class="btn btn-success" value="Save" ng-click="uploadPic(picFile)">

将名称作为form/multipart中的单独部分发送：

  $scope.uploadPic = function(file) {
    file.upload = Upload.upload({
      url: 'http://localhost:3000/upload',
      data: {file: file,
             name: file.name},
    });
