复制代码 代码如下:
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['region']=='湖北省' && !iscrawler()){
        exit('http://www.a.net');
    }
