Apache服务器URL重写

比如这是一张图片地址为：D:\Tim\PhpStudy2018\PHPTutorial\WWW\Uploadfile\Uploads\admin\2018-05-25\5b07b9cc1494c.jpg

需要在浏览器中以短地址方式显示这张图片，比如打开短地址: 127.0.0.1/Uploadfile/file/5b07b

这时需要用的URL重写:

要点1.建立控制器GetfileController.class.php

header()函数参考:http://www.jb51.net/article/127401.htm

<?php
namespace Admin\Controller;
use Think\Controller;
class GetfileController extends InitializeController {
    public function index()
    {
        $filesDB = M('files');
        $code = $_GET['code'];
        $web_path = dirname(THINK_PATH);   //D:\Tim\PhpStudy2018\PHPTutorial\WWW\Uploadfile
        if(!isset($code)){
            header("Content-Type:image/png");  
            echo file_get_contents($web_path .'/image/none.png');
            exit();
        }
        $row = $filesDB->where(" `keycode` = '$code' ")->find();

        if(!isset($row) || !isset($row['filepath'])){
            header("Content-Type:image/png"); 
            echo file_get_contents($web_path .'/image/none.png');
            exit();
        }

        $filepath = $row['filepath']; //比如: ./Uploads/admin/2018-05-25/5b07b9cc1494c.jpg
        $filetype = $row['filetype']; //"application/octet-stream";
        $filename = $row['filename'];
        header("Content-Type:$filetype"); 
        if(strlen($filetype)>5 && strtolower( substr($filetype, 0, 5))!="image"){
            header('Content-Disposition: attachment; filename="'.$filename.'"');
        }
        echo file_get_contents($web_path . $filepath);
    }
}
?>

要点2.数据库中设计到文件的类型:

 

要点3.Thinkphp框架中修改.htaccess文件:

(.htaccess文件在项目的根目录下)

<IfModule mod_rewrite.c>

  Options +FollowSymlinks

  RewriteEngine On

  RewriteCond %{REQUEST_FILENAME} !-d

  RewriteCond %{REQUEST_FILENAME} !-f

  RewriteRule ^file/([0-9a-zA-Z]*+) admin.php/Admin/Getfile/index?code=$1 [L]

</IfModule>
