存储来自Google OAuth 2.0的访问令牌，以便从应用程序帐户访问驱动器数据

Question

我能够使用python执行quickstart.py for Google Drive。但是，我们如何存储令牌并再次使用它—再次为同一用户而不提示用户。是他们的一些方式，我可以映射用户访问令牌时，发送请求的文件在谷歌驱动器。

Answer 1

google-api-python-client提供了许多不同的Storage类型，其中一些有很好的文档。

一些例子:<标题> oauth2client.file.Storage:

from oauth2client.file import Storage
...
storage = Storage('a_credentials_file')
storage.put(credentials)
...
credentials = storage.get()

<标题> oauth2client.keyring_storage.Storage:

from oauth2client.keyring_storage import Storage
...
storage = Storage('application name', 'user name')
storage.put(credentials)
...
credentials = storage.get()

<标题> oauth2client.appengine.StorageByKeyName:

from oauth2client.keyring_storage import StorageByKeyName
from oauth2client.keyring_storage import CredentialsNDBModel
...
storage = StorageByKeyName(CredentialsNDBModel, some_user_id, 'credentials')
storage.put(credentials)
...
credentials = storage.get()

<标题> oauth2client.django_orm.Storage:

from django.contrib.auth.models import User
from oauth2client.django_orm import Storage
from your_project.your_app.models import CredentialsModel
...
user = # A User object usually obtained from request.
storage = Storage(CredentialsModel, 'id', user, 'credential')
credential = storage.get()
...
storage.put(credential)

我认为你应该给bossylobster一个更完整的答案，但是根据你的评论，这正是我的设置，我使用Storage类增强了quickstart.py:

#!/usr/bin/python                                                                                                                         
import httplib2
import pprint
from apiclient.discovery import build
from apiclient.http import MediaFileUpload
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.file import Storage
# Copy your credentials from the console                                                                                                  
CLIENT_ID = 'PASTE_YOUR_ID'
CLIENT_SECRET = 'PASTE_YOUR_SECRET'
# Check https://developers.google.com/drive/scopes for all available scopes                                                               
OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'
# Redirect URI for installed apps                                                                                                         
REDIRECT_URI = 'urn:ietf:wg:oauth:2.0:oob'
# Create a credential storage object.  You pick the filename.
storage = Storage('a_credentials_file')
# Attempt to load existing credentials.  Null is returned if it fails.
credentials = storage.get()
# Only attempt to get new credentials if the load failed.
if not credentials:
    # Run through the OAuth flow and retrieve credentials                                                                                 
    flow = OAuth2WebServerFlow(CLIENT_ID, CLIENT_SECRET, OAUTH_SCOPE, REDIRECT_URI)
    authorize_url = flow.step1_get_authorize_url()
    print 'Go to the following link in your browser: ' + authorize_url
    code = raw_input('Enter verification code: ').strip()
    credentials = flow.step2_exchange(code)
    storage.put(credentials)

# Create an httplib2.Http object and authorize it with our credentials                                                                    
http = httplib2.Http()
http = credentials.authorize(http)
drive_service = build('drive', 'v2', http=http)
# Use 'drive_service' for all of the API calls
