Question

我在我的网站链接上下载了一些文件：

<a href="documents/myfile.pdf">Download</a>

但是，当我点击链接时，浏览器不会自动下载此文件，而是将我重定向到文件网址http://example.com/documents/myfile.pdf，我会在其中看到其内容。我只知道我的.htaccess文件存在一些问题，但我不知道它可能是什么。我在html5boilerplate项目中使用.htaccess，你可以在这里预览源代码：https://raw.githubusercontent.com/h5bp/html5-boilerplate/master/dist/.htaccess。我很感激帮助。

Answer 1

您可以尝试：

<FilesMatch "\.(gz|pdf|zip|rar)$" >
    Order allow,deny
    Allow from all
    Satisfy any
</FilesMatch>

Answer 2

也许您可以使用HTML5下载属性：http://davidwalsh.name/download-attribute

可能重复： (HTML) Download a PDF file instead of opening them in browser when clicked

Answer 3

<强>解决方案：

<FilesMatch "\.(txt|pdf|zip|rar)$">

  ForceType application/octet-stream
  Header add Content-Disposition "attachment"

  Order allow,deny
  Allow from all
  Satisfy any

</FilesMatch>

Answer 4

使用htaccess强制下载文件的最佳方法是在这里。我提供了一个完整的示例，将所有文件放在root中并测试它们：）

的.htaccess

RewriteEngine on
RewriteRule ^(.*).(txt|pdf|zip|rar)$ /download.php?file=$1.$2 [R,L]

的download.php

<?php
  if (!empty($_GET['file'])) {
    $file = basename($_GET['file']);
    $type = array("txt", "pdf", "zip", "rar");
    $exts = strtolower(substr(strrchr($file, "."), 1));
    if (!in_array($exts, $type)) {
      header("HTTP/1.0 403 Forbidden");
      exit('File not allowed!');
    } else {
      if (file_exists($file)) {
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename="' . $file . '"');
        header('Content-Transfer-Encoding: binary');
        header('Connection: Keep-Alive');
        header('Expires: 0');
        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
        header('Pragma: public');
        header('Content-Length: ' . sprintf("%u", filesize($file)));
        $fh = fopen($file, "rb");
        while (!feof($fh)) {
          echo fgets($fh);
          flush();
        }
        fclose($fh);
        exit;
      } else {
        header("HTTP/1.0 404 Not Found");
        exit('File not found!');
      }
    }
  }
?>
