从 SharePoint 以编程方式使用 Python 代码下载时 Xlsx 文件已损坏：如何解决？

如何解决从 SharePoint 以编程方式使用 Python 代码下载时 Xlsx 文件已损坏：如何解决？

我正在使用以下 Python 代码连接 SharePoint 并下载特定文件。虽然文件正在下载到我设置的本地文件夹，但我无法打开下载的文件。尝试打开文件时，我收到一条错误消息，指出文件已损坏或格式不受支持

知道如何解决吗？还是使用更好的解决方案？

    with open(localPathForDownload+fileName,"wb") as local_file:
          local_file.write(response.content)
