//根据ip获得当前位置信息
use GeoIp2\Database\Reader;
function get_ip_location($ip = ''){
    if (empty($ip)) return [];
    //import('autoload',EXTEND_PATH.'GeoIP2/vendor');
    require 'GeoIP2/vendor/autoload.php'
    // This creates the Reader object, which should be reused across
    // lookups.
    //$reader = new Reader(EXTEND_PATH.'GeoIP2/maxmind-db/city_20180703/GeoLite2-City.mmdb');
    $reader = new Reader('GeoIP2/maxmind-db/city_20180703/GeoLite2-City.mmdb');
    $return = [];
    // Replace "city" with the appropriate method for your database, e.g.,
    // "country".
    $record = $reader->city($ip);
    $return['isoCode'] = $record->country->isoCode;
    $return['country_name'] = $record->country->name;
    $return['cn_country_name'] = $record->country->names['zh-CN'];
