Question

我有一个页面，用户点击＆＃34; DOWNLOAD＆＃34;按钮。这将打开一个模式，需要CODE来授权下载。

插入后，CODE将被提交给PHP脚本，该脚本验证代码并恢复文件OUTSIDE webroot并需要强制下载。

但是，我在Firebug中看到脚本＆＃34;回声＆＃34;文件内容......

我需要＆＃34;关闭＆＃34;模式和强制下载。非常感谢你！

JQUERY提交

var data = $form.serialize();
            data = data+'&ajax=true';
            $.ajax({
                    data    : data,
                    type    : $form.attr('method'),
                    url     : $form.attr('action'),
                    success : function(response) {
                        // nothing to do here
                    } // success
            });

PHP脚本

// other stuffssss
if ($validate===true) {
                // IL PIN E' CORRETTO, TIRIAMO FUORI IL CEDOLINO
                $payroll = $this->service->getPayroll($id_payroll,'id',null,'ASC',1);
                $path = \SupportText::removeSubstringFromString($this->f3->get('SERVER.DOCUMENT_ROOT'), '/httpdocs').'/private';
                $filename = $path.'/'.$this->id_user.'/'.$payroll[0]->filename;
                \SupportFile::returnFile($filename);
                exit;
            }

PHP SupportFile类

class SupportFile {

    public static function returnFile( $filename ) {
        // Check if file exists, if it is not here return false:
        if ( !file_exists( $filename )) return false;
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        // Suggest better filename for browser to use when saving file:
        header('Content-Disposition: attachment; filename='.basename($filename));
        header('Content-Transfer-Encoding: binary');
        // Caching headers:
        header('Expires: 0');
        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
        header('Pragma: public');
        // This should be set:
        header('Content-Length: ' . filesize($filename));
        // Clean output buffer without sending it, alternatively you can do ob_end_clean(); to also turn off buffering.
        ob_clean();
        // And flush buffers, don't know actually why but php manual seems recommending it:
        flush();
        // Read file and output it's contents:
        readfile( $filename );
        // You need to exit after that or at least make sure that anything other is not echoed out:
        exit;
    }

}

尝试使用ob_start（）;在header（）之前。然后使用下面的代码

class SupportFile {

 public static function returnFile( $filename ) {
    if ( !file_exists( $filename )) return false;

    ob_strat();

    header('Content-Description: File Transfer');
    header('Content-Disposition: attachment; filename='.basename($filename));
    header("Content-Length: " . filesize($filename));
    header('Content-Type: '.mime_content_type($filename));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($filename));
    ob_end_clean(); 
    ob_clean();
    flush();
    readfile( $filename );
    exit;
  }
}
