php通過淘寶API查詢IP地址歸屬等信息

淘寶公司提供了一個很好用的IP地理信息查詢接口。

在這里:http://ip.taobao.com/

TaobaoIPQuery2這個類將極大的簡化相關的信息查詢。

類 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：

<?phpClass 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',  );}

調用：

$ip = $_SERVER["REMOTE_ADDR"];$ipquery = new taobaoIPQuery($ip);$region = $ipquery->get_region();$country = $ipquery->get_country();$city = $ipquery->get_city();

我們再來看個騰訊api接口的

/*  *根據騰訊IP分享計劃的地址獲取IP所在地，比較精確  */ 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) ; // 獲取數據返回   $result = curl_exec($ch);   $result = mb_convert_encoding($result, "utf-8", "gb2312"); // 編碼轉換，否則亂碼   curl_close($ch);   preg_match("@<span>(.*)</span></p>@iU",$result,$ipArray);   $loc = $ipArray[1];   return $loc; }

騰訊的IP分享計劃的查詢接口連接是：http://ip.qq.com/cgi-bin/searchip，該連接后面會帶有一個get參數searchip1，即searchip1=你要查詢的IP地址。采用PHP向http://ip.qq.com/cgi-bin/searchip發送http get request，然后獲取相應，獲得相應結果后，將結果用正則表達式將需要的地理位置信息提取出來就OK了。當然，PHP發送get請求的方法有很多，我用curl來模擬http請求的方法

Curl是PHP的一個擴展，進行測試之前，先確認PHP已經加載了curl擴展。打開PHP配置文件php.ini，搜索 “extension=php_curl.dll”，將其前面的分號（;）去掉，然后重啟HTTP服務器，查看phpinfo()，若能看到curl的信息，說明PHP擴展curl成功

接下來是新浪網的API接口

新浪的IP查詢接口地址是：http://int.dpool.sina.com.cn/iplookup/iplookup.php，該連接后面也帶有get參數，參數ip=你要查詢的IP地址，format=返回的查詢結果格式。為了方便起見，返回的格式采用json，即format=json，因此，PHP出來擴展curl外，還得擴展json：

/*  *根據新浪IP查詢接口獲取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) ; // 獲取數據返回   $location = curl_exec($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。
