Question

我使用CodeIgniter3来构建项目。但是我不确定存储生成的PDF文件的最佳位置在哪里。由于它的大小，我不想让它们保留在MySQL中。

我不希望别人访问直接链接，例如：http://mydomain/pdf/file.pdf 但我想为codeigniter登录用户提供这种访问权限。

最好的方法是什么？

Answer 1

创建site/pdf_files/.htaccess文件并添加以下行：
```
Deny from all
```

按如下方式进行路由器配置

/*
 anything in second segment of pdf controller will be routed to
 index method 

 serve file like : 
 http://example.com/pdf/myfile.pdf
*/
$route['pdf/(:any)'] = "pdf/index/$1";

/*
 Note: if you got some more methods in same controller prefer below one
 because, with above one, anything in second segment will be routed to 
 index method  

 $route['pdf/display/(:any)'] = "pdf/index/$1";

 and serve files like
 http://example.com/pdf/display/myfile.pdf
*/

然后在向用户提供pdf时更喜欢codeigniter文件助手，如下所示

class Pdf extends CI_Controller
{

function download_file($path, $name)
{
  // make sure it's a file before doing anything!
  if(is_file($path))
  {

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

    header('Content-Type: '.get_mime_by_extension($path));  
    header('Content-Disposition: attachment; filename="'.basename($name).'"');  // Add the file name
    header('Content-Transfer-Encoding: binary');
    header('Content-Length: '.filesize($path)); // provide file size
    header('Connection: close');
    readfile($path); 
    die();
  }
}

 public function index($file)
 {
    // here you check whether user logged in or not

     $this->download_file('pdf_files/'.$file, $file);
 }
}

Answer 2

将PDF文档根目录外的PDF存储在非公开的位置。

您可以使用应用程序逻辑来允许登录用户查看/访问：

class pdf extends ci_controller{

     public function view()
     {
        //check if user is logged in and has permission to view
        //set proper header information
        //readfile('non_public_path\to\pdf);
     }

}

只要你的pdf在你的公共目录之外 - 发送请求 domain.com/pdf/view只会在用户登录并有权查看时呈现pdf。
