免费IP归属地查询接口汇总
代码实现
网络请求库，使用 Requests（PHP：rmccue/requests进行网络请求）
通过ip获取位置信息不太准确，需要对获取的省市县三级区域码做判断处理
<?php namespace app\service; use app\common\AppException; use Requests; class IpService { public static function getIpInfo($ip) { $base_url = 'http://whois.pconline.com.cn/ipJson.jsp'; $params = [ 'ip' => $ip, // 注意，此处不能写boolean值，需要给string 'json' => 'true' ]; $url = $base_url . '?' . http_build_query($params); $response = Requests::get($url); if ($response->success) { // 编码转换处理，并移除字符串两边的空白 $body=iconv("GBK", "UTF-8", trim($response->body)）; $data = json_decode($body, true); // 优先取区县码 $code = $data['regionCode']; // 其次取城市码 if (!self::isRegionCode($code)) { $code = $data['cityCode']; } //再次取省份码 if (!self::isRegionCode($code)) { $code = $data['proCode']; } return [ 'ip' => $data['ip'], 'code' => $code ]; // 此处仅返回区位码即可 return [ 'ip' => $data['ip'], 'code' => $data['regionCode'], ]; } else { throw new AppException('ip信息获取失败'); } } public static function isRegionCode($code) { if (empty($code) || count($code) != 6) { return false; } else { return true; } } }
异常类
<?php namespace app\common; use Exception; /** * 自定义的业务异常 * Class AppException * @package app\common */ class AppException extends Exception { }
