    $upload = new \Think\Upload($config);
    // 实例化上传类 // 上传单个文件 $info = $upload->uploadOne($_FILES['test']);
    if(!$info) {
    // 上传错误提示错误信息 $qrcode_path_new = './Public/Home/images/code'.'_'.date("Ymdhis").'.png';
    $content = $_POST['content'];
    $matrixPointSize = $_POST['matrixPointSize'];
    $matrixMarginSize = $_POST['matrixMarginSize'];
    $errorCorrectionLevel = $_POST['errorCorrectionLevel'];
    makecode_no_pic($content,$qrcode_path_new,$matrixPointSize,$matrixMarginSize,$errorCorrectionLevel);
    $this->assign('img',$qrcode_path_new);
}
else {
    $qrcode_path = "./upload/".$info['savepath'].$info['savename'];
    $content = $_POST['content'];
    $matrixPointSize = $_POST['matrixPointSize'];
    $matrixMarginSize = $_POST['matrixMarginSize'];
    $errorCorrectionLevel = $_POST['errorCorrectionLevel'];
    $url = "./upload/qrcode/".date("YmdHis").".png";
    makecode($qrcode_path,$content,$matrixPointSize,$matrixMarginSize,$errorCorrectionLevel,$url);
    $this->assign('img',$url);
}
$this->display();
}
