PHP queries IP address ownership and other information through Taobao API, _PHP tutorial

php queries IP address ownership and other information through Taobao API.

Taobao company provides a very useful IP geographical information query interface.

Here: http://ip.taobao.com/

TaobaoIPQuery2 This class will greatly simplify related information query.

Class TaobaoIPQuery2 File:

<&#63;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_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',

TaobaoIPQuery2.Class.php：

<&#63;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();
    $options = array(
      CURLOPT_URL => sprintf('%s&#63;%s', self::$_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',
  );
}

Call:

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

Let’s take a look at the Tencent API interface

/* 
 *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; 
} 

The query interface connection of Tencent’s IP sharing plan is: http://ip.qq.com/cgi-bin/searchip. The connection will be followed by a get parameter searchip1, that is, searchip1=the IP address you want to query. . Use PHP to send an http get request to http://ip.qq.com/cgi-bin/searchip, and then obtain the response. After obtaining the corresponding result, use the result to extract the required geographical location information using regular expressions and it is OK. Of course, there are many ways to send get requests in PHP. I use curl to simulate the http request method

Curl is an extension of PHP. Before testing, make sure that PHP has loaded the curl extension. Open the PHP configuration file php.ini, search for "extension=php_curl.dll", remove the semicolon (;) in front of it, then restart the HTTP server and check phpinfo(). If you can see curl information, it means that PHP extends curl Success

The next step is Sina.com’s API interface

Sina’s IP query interface address is: http://int.dpool.sina.com.cn/iplookup/iplookup.php. The connection also has a get parameter behind it. The parameter ip=the IP address you want to query. format=The returned query result format. For convenience, the returned format is json, that is, format=json. Therefore, in addition to extending curl, PHP must also extend 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; 
} 

Use getIPLoc_sina("183.37.209.57") to get the address location of the IP address.
