How to upload a multi-part file with xhrRequestAdapter?

[proddy]

I'm using FormData() to upload files. Using axiosRequestAdapter as the requestAdapter works fine (following the example https://alova.js.org/tutorial/extension/alova-adapter-axios/#upload) but the whole point of me porting my code from axios to alova was not to use axios and save on space as the library states "4kb+, only 30% of axios+".

Is there a way to upload multi-part files using the xhrRequestAdapter as well?

@JOU-amjs any thoughts on how to do this? I've tried every option by setting the header and appending the boundary with 'Content-Type': 'multipart/form-data; boundary=${formData._boundary}' but still can't get it to work. This is the last thing I need to port and them I'm Axios free!

I think this may be a bug so I will create a new GH issue.
