php – Codeigniter强制下载文件

通过执行codeigniter文档,我使用以下代码强制从我的服务器下载文件.

function download($file_id){
        $file = $this->uploadmodel->getById($file_id); //getting all the file details
                                                      //for $file_id (all details are stored in DB)
        $data = file_get_contents($file->full_path); // Read the file's contents
        $name = $file->file_name;;

        force_download($name,$data);
    }

代码是图像的工作文件,但是当与PDF文件一起使用时,它不起作用.我没有测试所有文件扩展名,但由于它不适用于PDF,它可能不适用于其他各种文件类型.
任何解决方案？

我有类似的问题,我认为问题在于某些mime和头文件发送到浏览器.我最终使用我在这里找到的代码 http://taggedzi.com/articles/display/forcing-downloads-through-codeigniter.使用下面的功能而不是force_download.到目前为止我已经为我工作了.

function _push_file($path,$name)
{
  // make sure it's a file before doing anything!
  if(is_file($path))
  {
    // required for IE
    if(ini_get('zlib.output_compression')) { ini_set('zlib.output_compression','Off'); }

    // get the file mime type using the file extension
    $this->load->helper('file');

    $mime = get_mime_by_extension($path);

    // Build the headers to push out the file properly.
    header('Pragma: public');     // required
    header('Expires: 0');         // no cache
    header('Cache-Control: must-revalidate,post-check=0,pre-check=0');
    header('Last-Modified: '.gmdate ('D,d M Y H:i:s',filemtime ($path)).' GMT');
    header('Cache-Control: private',false);
    header('Content-Type: '.$mime);  // Add the mime type from Code igniter.
    header('Content-Disposition: attachment; filename="'.basename($name).'"');  // Add the file name
    header('Content-Transfer-Encoding: binary');
    header('Content-Length: '.filesize($path)); // provide file size
    header('Connection: close');
    readfile($path); // push it out
    exit();
}

希望它有帮助.
