在Python中从Google API获取文件元数据
我现在正在尝试用Python从谷歌云盘下载文件的元数据。我基本上是从谷歌提供的文档中复制粘贴代码,之前都没什么问题。但是当我尝试调用:
drive_file = drive_service.files().get(id=file_id).execute()
时,我收到了以下错误:
drive_file = drive_service.files().get(id=file_id).execute()
File "build\bdist.win-amd64\egg\apiclient\discovery.py", line 452, in method
TypeError: Got an unexpected keyword argument "id"
不过,在谷歌的文档中,有一个示例在这里(在Python标签下),显示的内容和我写的几乎一模一样。我的代码不工作是因为我对Python不够熟悉,还是其他什么原因呢?完整的程序如下:
import httplib2
from apiclient.discovery import build
from oauth2client.client import OAuth2WebServerFlow
def getDriveService():
ClientID = <MY_CLIENT_ID>
ClientSecret = <MY_CLIENT_SECRET>
OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'
REDIRECT_URI = <MY_REDIRECT_URI>
flow = OAuth2WebServerFlow(ClientID, ClientSecret, OAUTH_SCOPE, REDIRECT_URI)
flow.redirect_uri = REDIRECT_URI
authorize_url = flow.step1_get_authorize_url()
print authorize_url
code = raw_input('Enter verification code: ').strip()
credentials = flow.step2_exchange(code)
http = httplib2.Http()
http = credentials.authorize(http)
return build('drive', 'v2', http=http)
drive_service = getDriveService()
files = drive_service.files().list().execute()
file_id = files['items'][0]['id']
#Error occurs here
drive_file = drive_service.files().get(id=file_id).execute()
print 'Title: %s' % drive_file['title']
print 'Description: %s' % drive_file['description']
print 'MIME type: %s' % drive_file['mimeType']

我解决了这个问题。
你可以修改这些代码
drive_file=drive_service.files().get(id=file_id).execute()
成
drive_file = drive_service.files().get(fileId=file_id).execute()
