在Laravel

Question

我使用fputcsv（）生成了一个CSV文件，然后从控制器返回下载的文件。它通过浏览器成功下载，但我也希望在下载后删除该文件。

//controller class
public function downloadCSV{
...
    return response()->download($filePath, $fileName, $headers);
}

我如何调用我的删除功能。

//controller class
csvService->deleteCSV($fileName);

//csvService class
public function deleteCSV($filename) {
    if (File::exists(storage_path($filename))) {
          File::delete(storage_path($filename));
    }
}

我尝试了以下内容。该文件未下载但已成功删除。

public function downloadCSV(...)
    ...
    response()->download($filePath, $fileName, $headers);

    return $csvService->deleteCSV($fileName);
}

Answer 1

使用deleteFileAfterSend方法：

return response()->download($filePath, $fileName, $headers)->deleteFileAfterSend(true);

File Download and Responses

//controller class
public function downloadAndDeleteCSV{
    ...
    return response()->download($filePath, $fileName, $headers)->deleteFileAfterSend(true);
}
