我发现了一个很棒的脚本,可以从以下目录下载和保护文件:
http://www.gowondesigns.com/?page.getfile
我也从一个网站上看到了这个代码:
// local file that should be send to the client
$local_file = 'test-file.zip';
// filename that the user gets as default
$download_file = 'your-download-name.zip';
// set the download rate limit (=> 20,5 kb/s)
$download_rate = 20.5;
if(file_exists($local_file) && is_file($local_file)) {
// send headers
header('Cache-control: private');
header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($local_file));
header('Content-Disposition: filename='.$download_file);
// flush content
flush();
// open file stream
$file = fopen($local_file, "r");
while (!feof($file)) {
// send the current file part to the browser
print fread($file, round($download_rate * 1024));
// flush the content to the browser
flush();
// sleep one second
sleep(1);
}
// close file stream
fclose($file);
}
else {
die('Error: The file '.$local_file.' does not exist!');
}
我如何将它们组合在一起?我的意思是,我如何使用getfile脚本并为其添加下载速率?
我试着添加:
while (!feof($file)) {
// send the current file part to the browser
print fread($file, round($download_rate * 1024));
// flush the content to the browser
flush();
// sleep one second
sleep(1);
}
但我认为应该是$fd,而不是$file,我没有得到积极的结果
我做错了什么?
根据您的评论-我认为您想要以下内容:
// open file stream
$file = fopen($local_file, "r");
while (!feof($file)) {
// send the current file part to the browser
print fread($file, round($download_rate * 1024));
// flush the content to the browser
flush();
// sleep one second
sleep(1);
}
// close file stream
fclose($file);
但是,您应该注意,正是整个脚本成功地提示用户下载文件并限制速度。只需将问题中的第一个脚本重命名为download.php,然后将其链接为<a href='download.php?id=1'>Download 1</a>
(然后文件ID 1将下载)。
<?php
$file_id = $_GET['id'];
if($file_id == 1){
// local file that should be send to the client
$local_file = 'test-file.zip';
// filename that the user gets as default
$download_file = 'your-download-name.zip';
} else {
die('Invalid file selected for download');
}
// set the download rate limit (=> 20,5 kb/s)
$download_rate = 20.5;
if(file_exists($local_file) && is_file($local_file)) {
// send headers
header('Cache-control: private');
header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($local_file));
header('Content-Disposition: filename='.$download_file);
// flush content
flush();
// open file stream
$file = fopen($local_file, "r");
while (!feof($file)) {
// send the current file part to the browser
print fread($file, round($download_rate * 1024));
// flush the content to the browser
flush();
// sleep one second
sleep(1);
}
// close file stream
fclose($file);
} else {
die('Error: The file '.$local_file.' does not exist!');
}
?>
<?php
$file = @$_GET["file"];
$rate = 100; // kb/sn
if (!file_exists($file)) {die("File Not Found");}
header("Content-Disposition: attachment; filename=" . $file);
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Description: File Transfer");
header("Content-Length: " . filesize($file));
flush(); // this doesn't really matter.
$fp = fopen($file, "r");
while (!feof($fp))
{
echo fread($fp, $rate * 1024);
flush();
sleep(1);
}
fclose($fp);
?>
我用这个。没问题。
