Laravel：无法下载生成的文件

Question

I have a function where I generates excel (.csv) file. Everything is working except download. So my idea was to download the file automatically in the browser after generating the csv file. When the file was generated we store it in the public folder. So when I call my function, the function is opening the url: http://127.0.0.1:8000/project/tools/export/exportData and displaying the file instead of downloading it. So for this I need your help. Thank you in advance: My codes :

public function exportData() {
 
$size=sizeof($arr);
   for($i=0; $i<$size; $i++)
   {
    fputcsv($fh,$arr[$i]);
   }
   fclose($fh);
   $file="Export.csv";
   $headers = array(

    'Content-Type: text/csv',

  );
   return response()->download($file, 'Export.csv', $headers);
  
}

Answer 1

You can add the content-disposition to your headers to indicate how to handle file:

$headers = [
    'Content-type'        => 'text/csv',
    'Content-Disposition' => 'attachment; filename="filename.csv"',
];

To display the file in the browser instead of downloading it, you would exchange attachment for inline .
