利用淘宝ip库限制地区访问

有些应用可能需要对某些地区的用户进行限制访问

在采用才此方法的时候，可以利用一些ip库对访问者的ip进行判断

淘宝ip库地址：淘宝ip库

从而对相应地区的用户进行对应的操作

下面的实例仅是限制了只能安徽省的用户访问

需要的用户可以进行相应的修改

$verification = '安徽省';//需要屏蔽省份的IP  $ip = $_SERVER['REMOTE_ADDR'];//获取访客IP  $antecedents = $_SERVER['HTTP_REFERER'];//访客来路地址  $result = file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=".$ip);//IP数据库来自淘宝。  $address = json_decode($result,true);  //判断访客是否属于XX省，是否来自百度，是否来自谷歌  if($address['data']['region'] != $verification && strpos($antecedents, 'baidu') === false && strpos($antecedents, 'google') === false){  echo "仅限安徽省用户访问";  exit();  }else{  echo "<script>window.location.href='/';</script>";  exit;  }

附文：从APNIC提取IP信息

保存成xx.sh的shell文件

#!/bin/bash# download from apnic
rm -f delegated-apnic-latest
wget http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest# IPs allocated to china.
grep 'apnic|CN|ipv4|' delegated-apnic-latest | cut -f 4 -d'|' > delegated-apnic-CN# get detail of echo IP from apnic database.
rm -f apnic_CN.txt
while read ip
do
# query apnic database
echo "query who is $ip"
whois -h whois.apnic.net $ip > tmp.txt
grep inetnum tmp.txt >> apnic_CN.txt # IP range
grep netname tmp.txt >> apnic_CN.txt # netname which include sp information
grep descr tmp.txt >> apnic_CN.txt # description which include province information
echo "" >> apnic_CN.txt
done < delegated-apnic-CN# clean up
rm -f tmp.txt
rm -f delegated-apnic-latest
rm -f delegated-apnic-CN
