利用淘宝IP库获取用户ip地理位置 我们查ip的时候都是利用ip138查询的,不过那个有时候是不准确的,还不如自己引用淘宝的ip库来查询,这样准确度还高一些。不多说了,介绍一下: 淘宝IP地址库 淘宝公布了他们的IP库http://ip.taobao.com/,还有REST API接口,

利用淘宝IP库获取用户ip地理位置


我们查ip的时候都是利用ip138查询的,不过那个有时候是不准确的,还不如自己引用淘宝的ip库来查询,这样准确度还高一些。不多说了,介绍一下:


淘宝IP地址库



淘宝公布了他们的IP库http://ip.taobao.com/,还有REST API接口,不过每个用户的访问频率需小于10qps,访问方    式:http://ip.taobao.com/service/getIpInfo.php?ip=[ip地址字串],返回内容以json格式的。具有IP查询,IP统计等功能。各大运营商拥有的IP数等信息。接下来介绍一下获取ip的实例:

  
/**


  * 通过淘宝IP接口获取IP地理位置


  * @param string $ip


  * @return: string


  **/


  function getCity($ip)


  {


  $url="http://ip.taobao.com/service/getIpInfo.php?ip=".$ip;


  $ipinfo=json_decode(file_get_contents($url));


  if($ipinfo->code=='1'){


  return false;


  }


  $city = $ipinfo->data->region.$ipinfo->data->city;


  return $city;


  }


  header("Content-Type:text/html;charset=utf-8");


  // 这样调用,显示山东省临沂市 (PS:^_^不错的php开发学习交流群:256271784,验证:csl,有兴趣的话可以加入进来一起讨论)


  var_dump(getCity("112.234.69.189"));


  ?>
Copy after login


调用的时候吧固定的ip替换成你想查询的ip就可以了。
