authcode

项目中用base64传输数据，使用后发现 base64 会有 +、/、= 三种特殊字符，会影响数据验证签名。所以在base64基础上进行了一次封装。保证数据传输过程无异常，并参考discuz的加密方法，为数据设置过期时间。

案例

include 'AuthCode.php';

//打包数据，获得串
$pack = AuthCode::pack([
    'name' => 'wolferhua',
    'mail' => '358273385@qq.com',
    'sex' => 'man',
    'site'=>'http://www.hashmop.com/'
]);

echo $pack . PHP_EOL;
