Python PyDrive没有downloadLink / exportLinks

Question

我正在使用pyDrive库，现在我需要获取xmls文件并读取它但我有错误

  

pydrive.files.FileNotDownloadableError：没有downloadLink / exportLinks   对于在元数据中找到的mimetype

white_list_xmls - 我的xmls文件

我的代码：

tmp_name = None
with NamedTemporaryFile(delete=False, suffix='.xlsx') as tf:
   tf.write(white_list_xmls.GetContentFile(white_list_xmls['title']))
      tf.flush()
      tmp_name = tf.name
   if tmp_name is not None:
      print(tmp_name)

然后我改变了这样的代码：

    tmp_name = None
                with NamedTemporaryFile(delete=False, suffix='.xlsx') as tf:
                    mimetypes = {
                        'application/vnd.google-apps.document': 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                        'application/vnd.google-apps.spreadsheet': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
                    }
                    if white_list_xmls['mimeType'] in mimetypes:
                        download_mimetype = mimetypes[white_list_xmls['mimeType']]
                        tf.write(white_list_xmls.GetContentFile(white_list_xmls['title'], mimetype=download_mimetype))
                        tf.flush()
                        tmp_name = tf.name
                if tmp_name is not None:
print(tmp_name)

但我也有错误：

  

TypeError：需要类似字节的对象，而不是＆＃39; NoneType＆＃39;
