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：，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：，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。
