淘宝ip地址查询类(使用淘宝ip库API接口)
我们在网站建设过程中经常需要用到显示访客IP的功能,这里提供一个简单的淘宝IP地址查询类,方便调用。
以下这个taobaoIPQuery类极大的简化了我们IP查询的过程
<?php
class taobaoIPQuery {
private $m_ip;
private $m_content;
public function __construct($ip) {
if (isset($ip)) {
$this->m_ip = $ip;
} else {
$this->m_ip = "";
}
if (!empty($this->m_ip)) {
$url_handle = curl_init();
curl_setopt($url_handle, CURLOPT_URL, "http://ip.taobao.com/service/getIpInfo.php?ip=" . $this->m_ip);
curl_setopt($url_handle, CURLOPT_RETURNTRANSFER, true);
$this->m_content = curl_exec($url_handle);
curl_close($url_handle);
if ($this->m_content) {
$this->m_content = json_decode($this->m_content);
if ($this->m_content->{'code'} == 1) {
exit("query error!");
}
} else {
exit("curl error!");
}
} else {
exit("ip address must be not empty!");
}
}
public function get_region() {
return $this->m_content->{'data'}->{'region'};
}
public function get_isp() {
return $this->m_content->{'data'}->{'isp'};
}
public function get_country() {
return $this->m_content->{'data'}->{'country'};
}
public function get_city() {
return $this->m_content->{'data'}->{'city'};
}
}
调用很简单
$ip = $_SERVER["REMOTE_ADDR"]; $ipquery = new taobaoIPQuery($ip); $region = $ipquery->get_region(); $country = $ipquery->get_country(); $city = $ipquery->get_city();
