MemoryError-如何使用Python通过Google Drive SDK下载大文件

从Google云端硬盘下载大文件时,我的内存不足.
我假设tmp = content.read(1024)不起作用,但是如何解决？
谢谢.

def download_file(service, file_id):
  drive_file = service.files().get(fileId=file_id).execute()
  download_url = drive_file.get('downloadUrl')
  title = drive_file.get('title')
  originalFilename = drive_file.get('originalFilename')
  if download_url:
    resp, content = service._http.request(download_url)
    if resp.status == 200:
      file = 'tmp.mp4'
      with open(file, 'wb') as f:
          while True:
              tmp = content.read(1024)
              if not tmp:
                  break
              f.write(tmp)
      return title, file
    else:
      print 'An error occurred: %s' % resp
      return None
  else:
    return None

解决方法:

正确的解决方案是实施部分下载.通过此过程,您将请求文件长度不同的块,直到完全下载为止.这是该过程的参考：https://developers.google.com/drive/web/manage-downloads#partial_download.
