通过淘宝IP库获取定位

//获取ip地址
function get_ip(){
    if (isset($_SERVER)) {
        if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
            $realip = $_SERVER['HTTP_X_FORWARDED_FOR'];
        } elseif (isset($_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 {

        }
    }
    return $realip;
}
 
   //淘宝库ip接口
    public function get_ip()
    {
        $ip = get_ip();
        $url = file_get_contents("http://ip.aliyun.com/outGetIpInfo?accessKey=alibaba-inc&ip=$ip");
        $res1 = json_decode($url,true);
