thinkphp中根据ip获取国家省市

这个业务逻辑多少都有点奇怪了，阅读浏览次数增值在新闻详情页的控制器方法里setInc，这怎么还写进模型事件里了。如果非要用onAfterRead也可以，把新闻文章的内容单独分出来一个news_content表，然后把它和news做关联，然后给news_content表的onAfterRead事件做增值处理，这样点进新闻页内查询到文章内容时才会触发它。: 评 TP6模型事件-查询后onAfterRead不好用

引入扩展文件

\extend\iplocation\Location.php

Location.php文件内容为：

<?php

namespace iplocation;

class Location {
    public static function GetIp(){
        $realip = '';
        $unknown = 'unknown';
        if (isset($_SERVER)){
            if(isset($_SERVER['HTTP_X_FORWARDED_FOR']) && !empty($_SERVER['HTTP_X_FORWARDED_FOR']) && strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'], $unknown)){
                $arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
                foreach($arr as $ip){
                    $ip = trim($ip);
                    if ($ip != 'unknown'){
                        $realip = $ip;
                        break;
                    }
                }
            }else if(isset($_SERVER['HTTP_CLIENT_IP']) && !empty($_SERVER['HTTP_CLIENT_IP']) && strcasecmp($_SERVER['HTTP_CLIENT_IP'], $unknown)){
                $realip = $_SERVER['HTTP_CLIENT_IP'];
            }else if(isset($_SERVER['REMOTE_ADDR']) && !empty($_SERVER['REMOTE_ADDR']) && strcasecmp($_SERVER['REMOTE_ADDR'], $unknown)){
                $realip = $_SERVER['REMOTE_ADDR'];
            }else{
                $realip = $unknown;
            }
        }else{
            if(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), $unknown)){
                $realip = getenv("HTTP_X_FORWARDED_FOR");
            }else if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), $unknown)){
                $realip = getenv("HTTP_CLIENT_IP");
            }else if(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), $unknown)){
                $realip = getenv("REMOTE_ADDR");
            }else{
                $realip = $unknown;
            }
        }
        $realip = preg_match("/[\d\.]{7,15}/", $realip, $matches) ? $matches[0] : $unknown;
        return $realip;
    }

    public static function GetIpLookup($ip = ''){
        if(empty($ip)){
            $ip = Location::GetIp();
        }
        $res = @file_get_contents('http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip=' . $ip);
        if(empty($res)){ return false; }
        $jsonMatches = array();
        preg_match('#\{.+?\}#', $res, $jsonMatches);
        if(!isset($jsonMatches[0])){ return false; }
        $json = json_decode($jsonMatches[0], true);
        if(isset($json['ret']) && $json['ret'] == 1){
            $json['ip'] = $ip;
            unset($json['ret']);
        }else{
            return false;
        }
        return $json;
    }
}

然后是使用，\app\home\controller\Index.php

内容为：

<?php
namespace app\home\controller;

use iplocation\Location;
use think\Controller;
class Index extends Controller{
    public function index(){
        $ip = $_SERVER["REMOTE_ADDR"];//获取客户端IP
        $info = (new Location()) -> GetIpLookup('222.74.21.206');//将ip换成$ip
        dump($info);
    }
}
