Laravel-excel: allow alter http headers before they get sent prior to download
In order to facilitate the use of a jquery plugin that implements an ajax like downloading experience:
http://johnculviner.com/jquery-file-download-plugin-for-ajax-like-feature-rich-file-downloads
The implementation requires a particular header to be sent back as part of the server side response which currently cannot be done within the LaravelExcelWriter::_download() method.
Utilising an event prior to sending headers would allow the default headers to be flexibly adjusted as required.

1.3.0 will have the ability to pass an array of headers as the 2nd parameter of the export() method:
->export('xls', [
'Set-Cookie' => 'fileDownload=true; path=/'
]);

How can I do this with version 3.1?

@andreshg112 you can add the use Exportable; Concern to the class e.g.
class MyExportClass implements FromView
{
use Exportable;
}
Then in your controller you can add the header:
return (new MyExportClass())->download('myexportfile.xlsx', \Maatwebsite\Excel\Excel::XLSX, [
'X-Vapor-Base64-Encode' => 'True'
]);
Documentation is here, took me a bit to figure out as well: https://docs.laravel-excel.com/3.1/exports/exportables.html
