本文介绍了使用php脚本从Server下载并重命名文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我需要一个脚本,让我可以访问www.website.com/getFile?id=2这样的文件,它下载文件并将其重命名为realFilename。
如何做到这一点?
解决方案
代码会做一个窍门你寻找
<?php
if(!is_numeric _GET ['id'])){//我们验证参数
echo'Wrong parameter';
exit();
}
$ oDb = new mysqli(ip,user,pass,databasename); //连接数据库
if($ oDb-> connect_errno){//检查错误
echo'Error';
exit();
}
$ oResult = $ oDb-> query('SELECT`pathOnServer`,`realFilename`
FROM --tablename--
WHERE id =' 。(int)$ _ GET ['id']。'
LIMIT 1'); // make query
if($ oResult-> num_rows!= 1){
echo'No file found';
exit();
}
$ oQuery = $ oResult-> fetch_object();
header('Content-disposition:attachment; filename ='。$ oQuery-> realFilename); // put special headers
readfile($ oQuery-> pathOnServer。$ oQuery-> id); //把文件
?>
您还可以使用filesize添加标题。
希望会帮助你。
I am storing all my files like "8asd98asd9as7d98asd9.file" and rerieve the "real" filename from a mysql-database: id (INT) AI PK, pathOnServer TEXT NOT NULL, realFilename VARCHAR(200) NOT NULL.
I need a script which allows me to access the files like "www.website.com/getFile?id=2" which downloads the file and renames it to "realFilename".
How can this be done?
解决方案
I do believe this code will do a trick you look for
<?php
if(!is_numeric($_GET['id'])) { // We validate parameter
echo 'Wrong parameter';
exit();
}
$oDb = new mysqli("ip","user","pass","databasename"); // Connecting to database
if($oDb->connect_errno) { // Check for an error
echo 'Error';
exit();
}
$oResult = $oDb->query('SELECT `pathOnServer`, `realFilename`
FROM --tablename--
WHERE id = '.(int)$_GET['id'].'
LIMIT 1'); // make query
if($oResult->num_rows != 1) {
echo 'No file found';
exit();
}
$oQuery = $oResult->fetch_object();
header('Content-disposition: attachment; filename='.$oQuery->realFilename); // put special headers
readfile($oQuery->pathOnServer.$oQuery->id); // put the file
?>
You could also add the header with filesize. Hope it will help you.
