php通过淘宝API查询IP地址归属等信息

前端技术 2023/09/05 PHP

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。
