.Chrome 会自动恢复下载.您也可以点击向下箭头向下箭头，然后点击继续"或更多"，然后点击继续"来继续下载文件.

. Chrome will automatically resume the download. You can also resume the file download by clicking the Down arrow Down Arrow and then Resume or More More and then Resume.

如果 1 和 2 不起作用.如果您尝试使用其他浏览器，那么问题出在您的文件和服务器上.

If 1 and 2 not work. and you trying with other browsers then the problem is in your file and server.

您可以通过检查 file_exists 来修复它并通过以下方式发送文件Yii2 sendFile.见例子:

You can fix it by checking file_exists and send file by Yii2 sendFile. see example:

$file_path = '/route/to/path/file.xlsx';
if (file_exists($file_path)) {
    return Yii::$app->response->sendFile($file_path);
}else{
    return 'file not found';
}

您可以在任何控制器中使用此代码.

you can use this code in any controller .
