With the development of the front-end framework, data separation between the front-end and back-end has become a trend. That is to say,
Example of submitting a vue axios form to upload images,
The element framework used in the project, and the requirement for adding data in the project is that images can be uploaded or not uploaded,
The problem is that the upload control in the element does not trigger the submission when there is no image, but the interface writes the multipart/form-data receiving mode with file.
Only one form can be imitated by the other.
Let file = e.tar get.

Then (function (response) {Console.log (response); }) .Catch(function (Error) {Console.log (error); });//optionally the request above could also is done asAxios.Get('/user'

The architecture I used before was both front and back, so there was a cross-domain problem. I wrote the Post request method based on Axios's official documentation on GitHub, but the error in the browser console console output cross-domain issues.Server I've done the cross-domain process
