Question

通过一个文件夹的元数据，我可以获取要下载到本地计算机的文件的相对文件路径。当我将此路径提供给do_get()的源代码时，它会向我提供权限被拒绝错误。这是代码，它应该下载文件并解密它们，但它无法直接下载文件。

  @command
  def do_decryptFiles(self, from_path, to_path, key):
    """
    Decrypt all the files given in the folder and subfolders of from_path 

    Examples:
    Dropbox> decryptFiles '/Photos' 'E:\temp' 'a13223132323232' 
    """

    folder_metadata = self.api_client.metadata(from_path)
    print "metadata:", folder_metadata
    for s in folder_metadata['contents']:
        if(s['is_dir'] == True):
            print "directory:", s['path']
        else:
            FFPath = s['path'] 
            print FFPath
            do_get(self, from_path, to_path)
            to_file = open(os.path.abspath(to_path), "wb")
            f, metadata = self.api_client.get_file_and_metadata(self.current_path + FFPath)
            to_file.write(f.read())

当它调用open()时，命令行给出了Permission Denied错误。任何帮助，将不胜感激。

发出本地目录权限问题？我最近遇到过类似的问题，如果它有一些可能的解决方案here。

听起来我觉得这不是Dropbox API问题，而是本地IO错误。

在Python中从Dropbox下载文件时出现权限被拒绝错误
