Does anyone know the best method for transferring an image from the frontend (using ANGULARJS) to the backend (Java) through a g Ajax call?
I want to save this image on a local server, utilizing streams. Any suggestions or tips would be greatly appreciated!
To achieve the desired functionality, you can implement a file input that remains hidden and is activated by clicking another element on the page.
Once you select a file using the file input, you can add the file to a FormData object and then send it as the post body in an ajax request.
var data = new FormData()
var file = document.getElementById('my-file-element').files[0]
data.set('key', file)
// Proceed with sending the ajax request including the form data.
Check out the FormData documentation
