我必须上传我从android应用程序收到的base64编码图像.我正在使用php codeigniter框架.在搜索论坛时,此链接上的问题如何在codeigniter中上传base64encoded图像与我的相同,但解决方案对我不起作用.

这是我写的代码:

private function _save_image() {
    $image = base64_decode($_POST['imageString']);
    #setting the configuration values for saving the image
    $config['upload_path'] = FCPATH . 'path_to_image_folder';
    $config['file_name'] = 'my_image'.$_POST['imageType'];
    $config['allowed_types'] = 'gif|jpg|jpeg|png';
    $config['max_size'] = '2048';
    $config['remove_spaces'] = TRUE;
    $config['encrypt_name'] = TRUE;


    $this->load->library('upload', $config);
    if($this->upload->do_upload($image)) {
        $arr_image_info = $this->upload->data();
        return ($arr_image_info['full_path']);
    }
    else {
        echo $this->upload->display_errors();
        die();
    }
}

我收到"你没有选择要上传的文件"

谢谢你的时间.
