引言

最近有点闲暇时间了,[email protected]

让PHP更快的提供文件下载》后,利用实际项目中的业务场景觉得有必须要去优化附件下载功能了。鸟哥的文章里面主要介绍的基于apache来做XSendfile讲解的,我有点强迫症,我对我的生产环境《顶岗实习管理系统》进行升级改造,我的webserver是nginx,所以基于nginx官方网站的 XSendfile

说明特做此改造笔记。

我的webroot目录在/var/vhost/demo,demo目录中存在一个uploadfiles文件夹,这个文件夹是存放用户上传的文件。比如一个用户上传一个hello.docx文件,那么它对应的物理路径应该是/var/vhost/demo/xsendfile/uploadfiles/hello.docx,如果我们以直接路径“http://demo.markdream.com/xsendfile/uploadfiles/hello.docx”来访问的话,那么我想对这个文件进行下载统计或者隐藏实体路径的话就只能使用php readfile()方法来把文件装载到内存中,在转发给客户端,如果文件超大的话,你的服务器估计很悬。所以我们要改进php下载方式,就是引言所阐述的利用nginx的XSendfile方式来传送文件给客户端,nginx默认已经包含了senfile模块了,你如果安装完nginx你会在nginx.conf文件会看到“sendfile on;”,OK说明你可以直接使用了不像apache那么复杂还要重新加载组件编译等等。好了我贴下我的配置文件和代码。

我的nginx虚拟主机配置文件

server {        listen 80;        server_name demo.markdream.com;        root /var/vhost/demo;        index  index.php;		# 这个是定义读取你的文件的目录的url开头  直接访问是不可以的 只能通过        location /protected {                internal;                alias   /var/vhost/demo/uploadfiles;        }        location ~ \.php$ {           fastcgi_pass   127.0.0.1:9000;           fastcgi_index  index.php;           fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;           include        fastcgi_params;        }}

一个简单的php下载文件脚本,downloads.php

<?php//eg: http://demo.markdream.com/xsendfile/downloads.php?filename=hello.docx// 获取文件名$filename = $_GET["filename"];// 你可以在这里写下你的查询数据库等你所想的功能 ……header ( "Content-type: application/octet-stream" );// 处理中文文件名$ua = $_SERVER ["HTTP_USER_AGENT"];if (preg_match ( "/MSIE/", $ua )) { $encoded_filename = rawurlencode ( $filename ); header ( 'Content-Disposition: attachment; filename="' . $encoded_filename . '"' );} else if (preg_match ( "/Firefox/", $ua )) { header ( "Content-Disposition: attachment; filename*=\"utf8''" . $filename . '"' );} else { header ( 'Content-Disposition: attachment; filename="' . $filename . '"' );}// 就这么简单一句话搞定 注意“protected”是和nginx配置文件的 protected要一致header("X-Accel-Redirect: /protected/" . $filename);?>
Copy after login

愉悦的demo

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
