织梦dedecms搜索功能禁止特定地区用户访问
由于很多人有一些需求在做国内站的时候,不做国内某个地区的业务的时候,他想屏蔽用户访问网站,我这边以dedecms搜索功能为例子,因为是以前开发的,时间比较有限现在,不重新调整做整站的功能,如果有需要,可以将以下相关代码放入一个php文件,然后在data/common.ini.php里面包含就可以了。目前网络上有很多资源,例如著名的珊瑚虫ip数据库,但是其文件在本地,得定时更新。我们现在使用淘宝ip数据库,通过json返回的数据来解析ip是否某地区,下面以"上海市"为例:
首页找到dedecms底下plus下的search.php文件,查找以下代码
if($cfg_notallowstr !='' && preg_match("#".$cfg_notallowstr."#i", $keyword))
{
ShowMsg("你的搜索关键字中存在非法内容,被系统禁止!","-1");
exit();
}
在上面加入
function get_ip_data(){
$ip=file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=".get_client_ip());
$ip = json_decode($ip);
if($ip->code){
return false;
}
$data = (array) $ip->data;
if($data['city']=='上海市' && !isCrawler()){
// exit('http://www.adminbuy.cn');
return true;
/* header("location:".getenv("HTTP_REFERER")); // 返回其调用页面 */
}
}
function isCrawler() {
$spiderSite= array(
"TencentTraveler",
"Baiduspider+",
"BaiduGame",
"Googlebot",
"msnbot",
"Sosospider+",
"Sogou web spider",
"ia_archiver",
"Yahoo! Slurp",
"YoudaoBot",
"Yahoo Slurp",
"MSNBot",
"Java (Often spam bot)",
"BaiDuSpider",
"Voila",
"Yandex bot",
"BSpider",
"twiceler",
"Sogou Spider",
"Speedy Spider",
"Google AdSense",
"Heritrix",
"Python-urllib",
"Alexa (IA Archiver)",
"Ask",
"Exabot",
"Custo",
"OutfoxBot/YodaoBot",
"yacy",
"SurveyBot",
"legs",
"lwp-trivial",
"Nutch",
"StackRambler",
"The web archive (IA Archiver)",
"Perl tool",
"MJ12bot",
"Netcraft",
"MSIECrawler",
"WGet tools",
"larbin",
"Fish search",
);
if(in_array(strtolower($_SERVER['HTTP_USER_AGENT']),$spiderSite)){
return true;
}else{
return false;
}
}
//获取客户端ip
function get_client_ip()
{
if (isset($_SERVER)){
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
$realip = $_SERVER["HTTP_X_FORWARDED_FOR"];
} else if (isset($_SERVER["HTTP_CLIENT_IP"])) {
$realip = $_SERVER["HTTP_CLIENT_IP"];
} else {
$realip = $_SERVER["REMOTE_ADDR"];
}
} else {
if (getenv("HTTP_X_FORWARDED_FOR")){
$realip = getenv("HTTP_X_FORWARDED_FOR");
} else if (getenv("HTTP_CLIENT_IP")) {
$realip = getenv("HTTP_CLIENT_IP");
} else {
$realip = getenv("REMOTE_ADDR");
}
}
return $realip;
}
if(get_ip_data())
{
ShowMsg("你的IP被禁止!","-1");
exit();
}
保存文件后,你让上海市的朋友访问,系统就会提示"你的IP被禁止!"的提示
