跟踪直接文件下载的最佳方法是什么？我找到了一些解决方案,例如：

http://www.gayadesign.com/diy/download-counter-in-php-using-htaccess/

但它对我不起作用,当我试图下载文件时我只得到一个空白页面我不知道它是否足够安全……

Google Analytics仅适用于javascript,无法跟踪直接文件下载.

Best是一个安全且自己的托管解决方案.

解决方法

随意使用:)

的.htaccess：

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

MySQL的：

CREATE TABLE `download` (
    `filename` varchar(255) NOT NULL,`stats` int(11) NOT NULL,PRIMARY KEY  (`filename`)
)

的download.php

<?php

mysql_connect("localhost","name","password")
or die ("Sorry,can't connect to database.");
mysql_select_db("dbname"); 
$baseDir = "/home/public_html/downloads"; 
$path = realpath($baseDir . "/" . basename($_GET['file'])); 

if (dirname($path) == $baseDir) {
if(!is_bot())
mysql_query("INSERT INTO download SET filename='".mysql_real_escape_string(basename($_GET['file']))."' ON DUPLICATE KEY UPDATE stats=stats+1");


header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=" . basename($_GET['file']));
header("Content-Length: ".filesize($path));
header("Content-Type: application/force-download");
header("Content-Transfer-Encoding: binary");
ob_clean();
ob_end_flush();
readfile($path);    
}

function is_bot()
{

    $botlist = array("Teoma","alexa","froogle","Gigabot","inktomi","looksmart","URL_Spider_SQL","Firefly","NationalDirectory","Ask Jeeves","TECNOSEEK","InfoSeek","WebFindBot","girafabot","crawler","www.galaxy.com","Googlebot","Scooter","Slurp","msnbot","appie","FAST","WebBug","Spade","ZyBorg","rabaz","Baiduspider","Feedfetcher-Google","TechnoratiSnoop","Rankivabot","Mediapartners-Google","Sogou web spider","WebAlta Crawler","TweetmemeBot","Butterfly","Twitturls","Me.dium","Twiceler");

    foreach($botlist as $bot)
    {
        if(strpos($_SERVER['HTTP_USER_AGENT'],$bot)!==false)
        return true;    // Is a bot
    }

    return false;
}

?>
