javascript - Get zip file from non-public folder (php) -

-

i have zip file in non-public folder of web server. want make file not accessible public, looking use php readfile read zip file , create file object zip file in javascript. not sure if best way appreciate suggestion.

how use returned data construct file object?

here php code (getzipfile.php):

<?php  $filename = "abc.zip";     $filepath = "/path/to/zip/";      // http headers zip downloads     header("pragma: public");     header("expires: 0");     header("cache-control: must-revalidate, post-check=0, pre-check=0");     header("cache-control: public");     header("content-description: file transfer");     header("content-type: application/octet-stream");     header("content-disposition: attachment; filename=\"".$filename."\"");     header("content-transfer-encoding: binary");     header("content-length: ".filesize($filepath.$filename));     ob_end_flush();     $buffer = readfile($filepath . $filename);     echo $buffer; ?>

and here javascript code

$.ajax({         url: 'getzipfile.php',         error: function(e) {             console.log(e);         },         datatype: 'text',         success: function(data) {             console.log(data);              var parts = [               new blob([data], {type: 'application/zip'}),               new uint16array([33])             ];              var f = new file(parts, "myzip.zip");         },         type: 'get'     });

one thing noticed size of th original zip file 2302 bytes, when print data.length in success function, data length 2287. should same?

where $buffer comes ? additionnaly don't seem sending file, should add : 

echo readfile($filepath . $filename);

you add control check if file exists, beyond question's scope.
