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。
