关于调用淘宝IP获取城市信息-- 随笔

首先获取客户端的IP地址

function getIPaddress(){
$IPaddress='';
if (isset($_SERVER)){
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
$IPaddress = $_SERVER["HTTP_X_FORWARDED_FOR"];
} else if (isset($_SERVER["HTTP_CLIENT_IP"])) {
$IPaddress = $_SERVER["HTTP_CLIENT_IP"];
} else {
$IPaddress = $_SERVER["REMOTE_ADDR"];
}
} else {
if (getenv("HTTP_X_FORWARDED_FOR")){
$IPaddress = getenv("HTTP_X_FORWARDED_FOR");
} else if (getenv("HTTP_CLIENT_IP")) {
$IPaddress = getenv("HTTP_CLIENT_IP");
} else {
$IPaddress = getenv("REMOTE_ADDR");
}
}
return $IPaddress;
}

再次通过调用淘宝API 查询城市信息

public function taobaoIP($clientIP){
$taobaoIP = 'http://ip.taobao.com/service/getIpInfo.php?ip='.$clientIP;
$IPinfo = json_decode(file_get_contents($taobaoIP));
$province = $IPinfo->data->region;
$city = $IPinfo->data->city;
$data = $province.$city;
return $data;
}

可以了
