背景：

我正在使用 ng-file-upload 在单独的 ngf-selects 和 Javascript 对象文字中提交两个文件。我遇到的问题是，当发送请求时，所有部分的内容配置都设置为表单数据，但我希望这两个文件的内容配置是附件。

问题：

有没有办法让我覆盖表单部分的内容配置，使其成为文件的附件而不是表单数据？

代码

因此，尽管没有一个库允许我这样做，但我仍然需要更改内容处置和其他事情，所以我在以下问题https://stackoverflow.com/a/28143262/844809的帮助下设法做到了

我仍在使用 ng-file-upload 来实现 UI 中的各种有用功能，但在控制器中我正在构建我自己的帖子。

(function () {
