Question

我使用django作为我的web框架，
我发现python-social-auth对于OAuth来说是一个很好的方案我还希望从谷歌OAuth2访问谷歌驱动器我在Google Drive SDK上看到了一些示例代码：

from apiclient.discovery import build

def build_service(credentials):

  http = httplib2.Http()
  http = credentials.authorize(http)
  return build('drive', 'v2', http=http)

所以，看起来我需要获取凭证来实例化服务器对象我该如何做才能获得凭据？或者我该怎么做才能使用谷歌驱动器？

Answer 1

我遇到了同样的情况，我一直在看oauth2client是如何工作的，所以我从使用python-social-auth认证获得的数据中生成了凭证，I当用户第一次登录网站时，将此逻辑放在管道中。如下：

import datetime
from django.conf import settings
from oauth2client import GOOGLE_REVOKE_URI, GOOGLE_TOKEN_URI
from oauth2client.client import OAuth2Credentials, _extract_id_token
from oauth2client.django_orm import Storage
from website.models import CredentialsModel


def set_google_credentials(strategy, details, response, user=None, *args, **kwargs):
    if user and kwargs.get('is_new'):
        token_expiry = datetime.datetime.utcnow() + datetime.timedelta(seconds=int(response.get('expires_in')))
        id_token = _extract_id_token(response.get('id_token'))
        credential = OAuth2Credentials(
            access_token=response.get('access_token'),
            client_id=settings.SOCIAL_AUTH_GOOGLE_PLUS_KEY,
            client_secret=settings.SOCIAL_AUTH_GOOGLE_PLUS_SECRET,
            refresh_token=response.get('refresh_token'),
            token_expiry=token_expiry,
            token_uri=GOOGLE_TOKEN_URI,
            user_agent=None,
            revoke_uri=GOOGLE_REVOKE_URI,
            id_token=id_token,
            token_response=response)
        storage = Storage(CredentialsModel, 'id', user, 'credential')
        storage.put(credential)

然后在我的设置中：

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.user.create_user',
    'myapp.pipeline.set_google_credentials'    
    # more pipelines
)

然后当我需要用户凭据时：

更新：由于@bcoover注意到Storage得到的结果需要解码和删除。

user = # get a user instance, from the request for example
storage = Storage(CredentialsModel, 'id', user, 'credential')
import pickle, base64
credentials = (pickle.loads(base64.b64decode(storage.get())))
# do what ever you want with the credentials

这种方法目前适用于我，但如果有人有更好的方法，我会感激不尽。 Storage和CredentialsModel来自https://developers.google.com/api-client-library/python/guide/django

这非常有帮助，谢谢@eyscode！我遇到了与@areyoueye相同的问题，结果看到谷歌代码后，结果需要解码和去除，然后效果很好！这是修改后的代码：

import pickle
...
storage = Storage(GoogleCredential, 'id', user, 'credential')
credentials = (pickle.loads(base64.b64decode(storage.get())))
...

然后执行print（），你应该得到一个像这样的输出对象：

...
print(credentials)
<oauth2client.client.OAuth2Credentials object at 0x7fa2837af630>
