php通过淘宝API查询IP地址归属等信息


            淘宝公司提供了一个很好用的IP地理信息查询接口。



在这里:http://ip.taobao.com/



TaobaoIPQuery2这个类将极大的简化相关的信息查询。

类 TaobaoIPQuery2 文件：





<?php

/* Usage:

 * $IPInfo = TaobaoIPQuery2::getIPInfo('IPAddress');

 */

Class TaobaoIPQuery2{

  private static $_requestURL = 'http://ip.taobao.com/service/getIpInfo.php';

  public static function getIPInfo($ip){

    $long = ip2long($ip);

    if($long === 0){

      throw new Exception('IP address error', 5);

    }

    $ip=long2ip($long);

    $IPInfo = self::queryIPInfo($ip);

    return self::parseJSON($IPInfo);

  }

  

  private static function queryIPInfo($ip){

    $query = http_build_query(array('ip'=>$ip));

    $ch = curl_init();

    $options = array(

      CURLOPT_URL => sprintf('%s?%s', self::$_requestURL, $query),

      CURLOPT_RETURNTRANSFER => true,

      CURLOPT_AUTOREFERER => false,

      CURLOPT_FOLLOWLOCATION => false,

      CURLOPT_HEADER => false,

      CURLOPT_TIMEOUT => 3.0,

    );

    curl_setopt_array($ch, $options);

    $content = curl_exec($ch);

    curl_close($ch);

    return $content;

  }

  

  private static function parseJSON($json){

    $O = json_decode ($json, true);

    if(false === is_null($O)){

      return $O;

    }

    if (version_compare(PHP_VERSION, '5.3.0', '>=')) {

      $errorCode = json_last_error();

      if(isset(self::$_JSONParseError[$errorCode])){

        throw new Exception(self::$_JSONParseError[$errorCode], 5);

      }

    }

    throw new Exception('JSON parse error', 5);

  }

  

  private static $_JSONParseError = array(

    JSON_ERROR_NONE=>'No error has occurred',  

    JSON_ERROR_DEPTH=>'The maximum stack depth has been exceeded',  

    JSON_ERROR_CTRL_CHAR=>'Control character error, possibly incorrectly encoded',  

    JSON_ERROR_STATE_MISMATCH=>'Invalid or malformed JSON',  

    JSON_ERROR_SYNTAX=>'Syntax error',  

    JSON_ERROR_UTF8=>'Malformed UTF-8 characters, possibly incorrectly encoded',

  );

}







TaobaoIPQuery2.Class.php：





<?php

Class TaobaoIPQuery2{

  private static $_requestURL = 'http://ip.taobao.com/service/getIpInfo.php';

  public static function getIPInfo($ip){

    $long = ip2long($ip);

    if($long === 0){

      throw new Exception('IP address error', 5);

    }

    $ip=long2ip($long);

    $IPInfo = self::queryIPInfo($ip);

    return self::parseJSON($IPInfo);

  }

  

  private static function queryIPInfo($ip){

    $query = http_build_query(array('ip'=>$ip));

    $ch = curl_init();

    $options = array(

      CURLOPT_URL => sprintf('%s?%s', self::$_requestURL, $query),

      CURLOPT_RETURNTRANSFER => true,

      CURLOPT_AUTOREFERER => false,

      CURLOPT_FOLLOWLOCATION => false,

      CURLOPT_HEADER => false,

      CURLOPT_TIMEOUT => 3.0,

    );

    curl_setopt_array($ch, $options);

    $content = curl_exec($ch);

    curl_close($ch);

    return $content;

  }

  

  private static function parseJSON($json){

    $O = json_decode ($json, true);

    if(false === is_null($O)){

      return $O;

    }

    if (version_compare(PHP_VERSION, '5.3.0', '>=')) {

      $errorCode = json_last_error();

      if(isset(self::$_JSONParseError[$errorCode])){

        throw new Exception(self::$_JSONParseError[$errorCode], 5);

      }

    }

    throw new Exception('JSON parse error', 5);

  }

  private static $_JSONParseError = array(

    JSON_ERROR_NONE=>'No error has occurred',  

    JSON_ERROR_DEPTH=>'The maximum stack depth has been exceeded',  

    JSON_ERROR_CTRL_CHAR=>'Control character error, possibly incorrectly encoded',  

    JSON_ERROR_STATE_MISMATCH=>'Invalid or malformed JSON',  

    JSON_ERROR_SYNTAX=>'Syntax error',  

    JSON_ERROR_UTF8=>'Malformed UTF-8 characters, possibly incorrectly encoded',

  );

}







调用：





$ip = $_SERVER["REMOTE_ADDR"];

$ipquery = new taobaoIPQuery($ip);

$region = $ipquery->get_region();

$country = $ipquery->get_country();

$city = $ipquery->get_city();







我们再来看个腾讯api接口的





/* 

 *根据腾讯IP分享计划的地址获取IP所在地，比较精确 

 */ 

function getIPLoc_QQ($queryIP){ 

  $url = 'http://ip.qq.com/cgi-bin/searchip?searchip1='.$queryIP; 

  $ch = curl_init($url); 

  curl_setopt($ch,CURLOPT_ENCODING ,'gb2312'); 

  curl_setopt($ch, CURLOPT_TIMEOUT, 10); 

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回 

  $result = curl_exec($ch); 

  $result = mb_convert_encoding($result, "utf-8", "gb2312"); // 编码转换，否则乱码 

  curl_close($ch); 

  preg_match("@<span>(.*)</span></p>@iU",$result,$ipArray); 

  $loc = $ipArray[1]; 

  return $loc; 

} 



腾讯的IP分享计划的查询接口连接是：http://ip.qq.com/cgi-bin/searchip，该连接后面会带有一个get参数searchip1，即searchip1=你要查询的IP地址。采用PHP向http://ip.qq.com/cgi-bin/searchip发送http get request，然后获取相应，获得相应结果后，将结果用正则表达式将需要的地理位置信息提取出来就OK了。当然，PHP发送get请求的方法有很多，我用curl来模拟http请求的方法

Curl是PHP的一个扩展，进行测试之前，先确认PHP已经加载了curl扩展。打开PHP配置文件php.ini，搜索 “extension=php_curl.dll”，将其前面的分号（;）去掉，然后重启HTTP服务器，查看phpinfo()，若能看到curl的信 息，说明PHP扩展curl成功

接下来是新浪网的API接口

新浪的IP查询接口地址是：http://int.dpool.sina.com.cn/iplookup/iplookup.php，该连接后面也带有get参数，参数ip=你要查询的IP地址，format=返回的查询结果格式。为了方便起见，返回的格式采用json，即format=json，因此，PHP出来扩展curl外，还得扩展json：





/* 

 *根据新浪IP查询接口获取IP所在地 

 */ 

function getIPLoc_sina($queryIP){ 

  $url = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$queryIP; 

  $ch = curl_init($url); 

  //curl_setopt($ch,CURLOPT_ENCODING ,'utf8'); 

  curl_setopt($ch, CURLOPT_TIMEOUT, 10); 

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回 

  $location = curl_exec($ch); 

  $location = json_decode($location); 

  curl_close($ch); 

   

  $loc = ""; 

  if($location===FALSE) return ""; 

  if (emptyempty($location->desc)) { 

    $loc = $location->province.$location->city.$location->district.$location->isp; 

  }else{ 

    $loc = $location->desc; 

  } 

  return $loc; 

} 







使用getIPLoc_sina("183.37.209.57")即可得到IP地址所在的地址位置。
