Binding form file using a struct

[confusionhill]

Hello, i got this requirement where the payload look like this

{
userID
file_type
file
}

I tried to do something like this

type UploadDocumentRequestDTO struct { UserID 'form:"uid"' File *multipart.FileHeader 'form:"file" validate:"required"' Msg string 'file:"msg" validate:"required"' }

doesn't seems to work.

Is it possible to do something like that?

Thank you
