python：我如何使用 api 从 Google 驱动器下载文件

Question

我想使用 google drive api 将 google drive 中的文件下载到我的系统。我该如何实现呢？

根据https://developers.google.com/drive/v2/reference/files/get#examples给出的例子

def print_file(service, file_id):

 """Print a file's metadata.

  Args:
    service: Drive API service instance.
    file_id: ID of the file to print metadata for.
  """
  try:
    file = service.files().get(fileId=file_id).execute()

    print 'Title: %s' % file['title']
    print 'MIME type: %s' % file['mimeType']
  except errors.HttpError, error:
    print 'An error occurred: %s' % error


def download_file(service, drive_file):
  """Download a file's content.

  Args:
    service: Drive API service instance.
    drive_file: Drive File instance.

  Returns:
    File's content if successful, None otherwise.
  """
  download_url = drive_file.get('downloadUrl')
  if download_url:
    resp, content = service._http.request(download_url)
    if resp.status == 200:
      print 'Status: %s' % resp
      return content
    else:
      print 'An error occurred: %s' % resp

我可以找到该文件，但是如何将其本地下载到我的机器上？

Answer 1

只需将内容变量写入文件而不是返回内容

fo = open("foo.jpg", "wb")
fo.write(content)
fo.close()

Answer 2

我想你应该看看这个：

代码看起来更简单

# Initialize GoogleDriveFile instance with file id.
file6 = drive.CreateFile({'id': file5['id']})
file6.GetContentFile('catlove.png') # Download file as 'catlove.png'.

# Initialize GoogleDriveFile instance with file id.
file7 = drive.CreateFile({'id': file4['id']})
content = file7.GetContentString()
# content: '{"firstname": "Claudio", "lastname": "Afshar"}'
