class Latlon{
    public static function getinfo($addr)
        {
            $url = sprintf(config('addr'),$addr);
            $client = new Client(['timeout' => 5,'verify' => false]);
            $response = $client->get($url);
            $json = (string)$response->getBody();
            $v['lng'] = substr(explode('lng":',$json)[1],0,10);
            $v['lat'] = substr(explode('lat":',$json)[1],0,10);
