firefox无法下载csv文件

Question

我正在尝试生成，然后默认使用php脚本下载csv文件。我有代码在chrome和Internet Explorer中工作正常，但相同的脚本在Firefox中不起作用。在firefox脚本中没有正确生成csv文件。以下是脚本

require('core.php');
$master = new db();
$s = $master->getRecords();
function array2csv(array &$array)
{
   if (count($array) == 0) {
     return null;
   }
   ob_start();
   $df = fopen("php://output", 'w');
   fputcsv($df, array_keys(reset($array)));
   foreach ($array as $row) {
      fputcsv($df, $row);
   }
   fclose($df);
   return ob_get_clean();
}

function download_send_headers($filename) {

     // disable caching
    $now = gmdate("D, d M Y H:i:s");
    header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
    header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
    header("Last-Modified: {$now} GMT");

    // force download  
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");


    // disposition / encoding on response body
    header("Content-Disposition: attachment;filename={$filename}");
    header("Content-Transfer-Encoding: binary");
    header("Content-Disposition: attachment;filename={$filename}");
    header("Content-Transfer-Encoding: binary");
}
download_send_headers(site_title .' '. date("d M Y") . ".csv");
echo array2csv($s);
die();

HTML和JS

<a class="list-group-item" href="javascript:void(0);" onclick="return exportUser();">Export to CSV</a> 

function exportUser(){ 
        $.ajax({
        url: 'get_csv.php',
        type: 'POST',
        success: function() {
            window.location = 'get_csv.php';
        }
    });
}

我还附上了截图供您理解。

Answer 1

尝试添加此标头：

header('Content-Type: application/csv; charset=utf-8');

Answer 2

您需要向js函数添加事件

函数exportUser（event）将执行此操作
