《PHP教程：php通過(guò)淘寶API查詢IP地址歸屬等信息》要點(diǎn)：
本文介紹了PHP教程：php通過(guò)淘寶API查詢IP地址歸屬等信息，希望對(duì)您有用。如果有疑問(wèn)，可以聯(lián)系我們。
PHP應(yīng)用淘寶公司提供了一個(gè)很好用的IP地理信息查詢接口.
PHP應(yīng)用在這里:http://ip.taobao.com/
PHP應(yīng)用TaobaoIPQuery2這個(gè)類將極年夜的簡(jiǎn)化相關(guān)的信息查詢.
PHP應(yīng)用類 TaobaoIPQuery2 文件：
PHP應(yīng)用
<?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',
);
}
PHP應(yīng)用TaobaoIPQuery2.Class.php：
PHP應(yīng)用
<?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',
);
}
PHP應(yīng)用調(diào)用：
PHP應(yīng)用
$ip = $_SERVER["REMOTE_ADDR"];
$ipquery = new taobaoIPQuery($ip);
$region = $ipquery->get_region();
$country = $ipquery->get_country();
$city = $ipquery->get_city();
PHP應(yīng)用我們?cè)賮?lái)看個(gè)騰訊api接口的
PHP應(yīng)用
/*
*根據(jù)騰訊IP分享計(jì)劃的地址獲取IP所在地,比較精確
*/
function getIPLoc_QQ($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(shù)據(jù)返回
$result = curl_exec($ch);
$result = mb_convert_encoding($result, "utf-8", "gb2312"); // 編碼轉(zhuǎn)換,否則亂碼
curl_close($ch);
preg_match("@<span>(.*)</span></p>@iU",$result,$ipArray);
$loc = $ipArray[1];
return $loc;
}
PHP應(yīng)用騰訊的IP分享計(jì)劃的查詢接口連接是：http://ip.qq.com/cgi-bin/searchip,該連接后面會(huì)帶有一個(gè)get參數(shù)searchip1,即searchip1=你要查詢的IP地址.采用PHP向http://ip.qq.com/cgi-bin/searchip發(fā)送http get request,然后獲取相應(yīng),獲得相應(yīng)結(jié)果后,將結(jié)果用正則表達(dá)式將需要的地理位置信息提取出來(lái)就OK了.當(dāng)然,PHP發(fā)送get哀求的方法有很多,我用curl來(lái)模擬http哀求的方法
PHP應(yīng)用Curl是PHP的一個(gè)擴(kuò)展,進(jìn)行測(cè)試之前,先確認(rèn)PHP已經(jīng)加載了curl擴(kuò)展.打開PHP配置文件php.ini,搜索 “extension=php_curl.dll”,將其前面的分號(hào)(;)去掉,然后重啟HTTP服務(wù)器,查看phpinfo(),若能看到curl的信 息,闡明PHP擴(kuò)展curl成功
PHP應(yīng)用接下來(lái)是新浪網(wǎng)的API接口
PHP應(yīng)用新浪的IP查詢接口地址是：http://int.dpool.sina.com.cn/iplookup/iplookup.php,該連接后面也帶有g(shù)et參數(shù),參數(shù)ip=你要查詢的IP地址,format=返回的查詢結(jié)果格式.為了便利起見,返回的格式采用json,即format=json,因此,PHP出來(lái)擴(kuò)展curl外,還得擴(kuò)展json：
PHP應(yīng)用
/*
*根據(jù)新浪IP查詢接口獲取IP所在地
*/
function getIPLoc_sina($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(shù)據(jù)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;
}
PHP應(yīng)用使用getIPLoc_sina("183.37.209.57")即可獲得IP地址所在的地址位置.
