dedecms 軟件下載頻道防盜鏈php代碼

字號(hào):


    因網(wǎng)站改版,以前的好多網(wǎng)站都是鏈接到我們的內(nèi)頁。導(dǎo)致達(dá)不到用戶體驗(yàn),也防止一些盜鏈我們資源的網(wǎng)站。
    dede做軟件站有的缺點(diǎn)
    就是別人轉(zhuǎn)帖你的下載的時(shí)候直接轉(zhuǎn)帖http://www.xxx.com/plus/download.php.........
    就是直接打開下載地址列表頁這種就可以下載了,耗費(fèi)資源卻又帶不了用戶。
    經(jīng)過研究,終于搞定了軟件頻道下載的防盜鏈,代碼發(fā)出來大家共享,希望能用的到
    改后的功能是
    假如軟件信息頁地址是:http://www.jb51.net/soft/1.htm
    下載地址連接是:http://www.jb51.net/plus/download.php?.........
    判斷來路,
    如果不是http://www.jb51.net/soft/1.htm,
    直接跳轉(zhuǎn)到http://www.jb51.net/soft/1.htm
    如果來路是http://www.jb51.net/soft/1.htm 則展示下載地址
    說明下:下邊的代碼是直接復(fù)制我自己站上的,我啟用的是全站迅雷下載,打開就自動(dòng)使用迅雷下載,你也可以做下小修改,不讓使用迅雷下載
    不使用迅雷的很容易修改:刪掉迅雷相關(guān)代碼,只引用$link就可以了
    需要修改的文件為 /plus/download.php
    演示:
    http://www.jb51.net/do/plus/download.php?open=0&aid=20975&cid=3
    必須從http://www.jb51.net/codes/20975.html這個(gè)頁面進(jìn)入才正常
    代碼如下:
    <script src="http://pstatic.xunlei.com/js/webThunderDetect.js"></script>
    <?php require("encode.inc"); ?>
    <?php
    require_once(dirname(__FILE__)."/../include/config_base.php");
    require_once(dirname(__FILE__)."/../include/inc_channel_unit.php");
    if(!isset($open)) $open = 0;
    if(!isset($aid)) $aid = "";
    $dsql = new DedeSql(false);
    //讀取文檔基本信息
    $arctitle = "";
    $arcurl = "";
    $gquery = "Select
    dede_archives.title,dede_archives.senddate,dede_archives.arcrank,
    dede_archives.ismake,dede_archives.typeid,dede_archives.channel,dede_archives.money,
    dede_arctype.typedir,dede_arctype.namerule
    From dede_archives
    left join dede_arctype on dede_arctype.ID=dede_archives.typeid
    where dede_archives.ID='$aid'
    ";
    $arcRow = $dsql->GetOne($gquery);
    if(is_array($arcRow)){
    $arctitle = $arcRow['title'];
    $arcurl = GetFileUrl($aid,$arcRow['typeid'],$arcRow['senddate'],$arctitle,$arcRow['ismake'],$arcRow['arcrank'],$arcRow['namerule'],$arcRow['typedir'],$arcRow['money']);
    }else{
    $dsql->Close();
    ShowMsg("無法獲取未知文檔的信息!","-1");
    exit();
    }
    $cu = new ChannelUnit($arcRow['channel'],$aid);
    if(!is_array($cu->ChannelFields)) {
    $cu->Close();
    $dsql->Close();
    ShowMsg("獲取文檔鏈接信息失??!","-1");
    exit();
    }
    $vname = "";
    foreach($cu->ChannelFields as $k=>$v){
    if($v['type']=="softlinks"){ $vname=$k; break; }
    }
    if(!is_array($cu->ChannelFields)) {
    $cu->Close();
    $dsql->Close();
    ShowMsg("獲取文檔鏈接信息失??!","-1");
    exit();
    }
    if(!strstr($_SERVER['HTTP_REFERER'],$arcurl))
    {
    echo "<script language='javascript'>location=\"$arcurl\";</script>";
    }
    $row = $dsql->GetOne("Select $vname From ".$cu->ChannelInfos['addtable']." where aid='$aid'");
    $downlinks = $cu->GetAddLinks($row[$vname]);
    $dsql->Close();
    $cu->Close();
    $link = base64_decode($link);
    $thunderUrl = ThunderEncode($link);
    echo "<script>OnDownloadClick('".$thunderUrl."','',location.href,'07231',2,'')</script>";
    ?>

    </div>

    </div>
    </div>

    </html>
    補(bǔ)充:
    1.本軟件頻道防盜鏈功能必須在軟件頻道設(shè)置中設(shè)置
    鏈接顯示方式: 要求進(jìn)入下載地址列表頁
    2.如果例子的情況與您網(wǎng)站的不一樣,您也可以手動(dòng)修改您的/plus/download.php
    修改方法如下:
    找到:
    $row = $dsql->GetOne("Select $vname From ".$cu->ChannelInfos['addtable']." where aid='$aid'");
    在他的上面加上
    if(!strstr($_SERVER['HTTP_REFERER'],$arcurl))
    {
    echo "<script language='javascript'>location=\"$arcurl\";</script>";
    }
    這樣就可以了.
