如何在编码器点火器中上传.ini文件

正在尝试在 Codeigniter 中上传.ini文件，但 CI 向我显示错误，不允许使用此文件类型。

我尝试将其放入哑剧中.php但没有奏效：

  $mimes = array('ini' => 'application/octet-stream')

我的代码是：

public function index()
{
$this->load->view('customer/upload/upload_ini', array('error' => ' ' ));
}
function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'ini';
    $this->load->library('upload', $config);
    $this->upload->initialize($config);

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());
        $this->load->view('customer/upload/upload_ini', $error);
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());
        $this->load->view('customer/upload/upload_success', $data);
    }
}
