}4 IP-API接口的整合案例
// 根据IP地址获取城市信息
protected function getCity($ip)
{
$url = "http://ip-api.com/json/".$ip."?lang=zh-CN";
$data = file_get_contents($url);
$data = json_decode($data, true);
if (!empty($data['status']) && $data['status'] == 'success') {
// 国家-省份-城市-经度,纬度
return $data['country'].'-'.$data['regionName'].'-'.$data['city'].'-'.$data['lon'].','.$data['lat'];
}
return '获取城市信息失败';
}
