背景：
我有一个表单，可以将两个文件连同以另一种表单创建的 Javascript 对象文字一起上传到服务器。
上传这些文件是可选的，因此可能没有，一个或两个，但始终需要 Javascript 对象文字。
表单正在工作，并且文件正在上传为无、一个或两个以及 Javascript 对象文字。
问题：
我遇到的问题是捕获响应并根据它采取行动。进度事件似乎被正确捕获，但看起来响应对象不是，这可能是我使用 ng-file-upload 的方式的副作用，或者可能只是服务器端没有返回正确的响应对象。
有人可以确认使用没问题吗？
我尝试将.error()和.success()添加到Upload.upload调用，但它说Upload.upload(...).then(...).error 不是函数或Upload.upload(.. .).then(...).success 不是函数
源代码：
这只是一个 POC，所以不是生产代码。
