Google正在弃用我正在使用的OpenID端点(我认为是v1.0,通过django_openid_auth
模块),我需要更新我的应用并迁移我的用户'帐户使用Google OAuth2。
我已将应用更改为使用python-social-auth
,并已成功通过social.backends.google.GoogleOAuth2
进行身份验证。
我已经编写了一个管道功能来查找旧表中的相关OpenID网址,这适用于我关心的其他后端但Google:
def associate_legacy_user(backend, response, uid=None, user=None,
*args, **kwargs):
if uid and not user:
# Try to associate accounts registered in the old openid table
identity_url = None
if backend.name == 'google-oauth2':
# TODO: this isn't working
identity_url = response.get('open_id')
else:
# for all other backends, see if there is a claimed_id url
# matching the identity_url use identity_url instead of uid
# as uid may be the user's email or username
try:
identity_url = response.identity_url
except AttributeError:
identity_url = uid
if identity_url:
# raw sql as this is no longer an installed app
user_ids = sql_query.dbquery('SELECT user_id '
'FROM django_openid_auth_useropenid '
'WHERE claimed_id = %s',
(identity_url,))
if len(user_ids) == 1:
return {'user': User.objects.get(id=user_ids[0]['user_id'])}
我最好通过阅读Google's migration guide告诉我,我需要在请求中添加openid.realm
,我已在settings.py中执行以下操作:
SOCIAL_AUTH_GOOGLE_OAUTH2_AUTH_EXTRA_ARGUMENTS \
= {'openid.realm': 'http://example.com/'}
但是这似乎没有返回传递给我的管道函数的open_id
中的response
值。
我似乎被卡在Step 3:
我尝试对后端进行子类化以更改RESPONSE_TYPE以添加id_token
但是返回了空响应:
import social.backends.google
class CustomGoogleOAuth2(social.backends.google.GoogleOAuth2):
RESPONSE_TYPE = 'code id_token'
我尝试向https://www.googleapis.com/oauth2/v3/token
添加类似于this example的额外请求,但我真的不知道如何将它们放在一起并进行调试。
更多细节:
claimed_id
内容如下:https://www.google.com/accounts/o8/id?id=AItOawmAW18QuHDdn6PZzaiI5BWUb84mZzNB9eo social.backends.google.GoogleOpenIdConnect
或类似的替代后端。虽然它似乎更接近Google文档所说的内容,但当我尝试时,我无法让它工作:
nonce
向social.backends.google.GoogleOpenIdConnect
添加id_token
,但我在RESPONSE_TYPE
中收到AuthMissingParameter
错误作为请求的端点,GET和POST为空。 (已尝试过代码id_token','令牌id_token',' id_token',...)/complete/google-openidconnect/
,因为它与我当前的登录表单不能很好地集成。social.backends.google.GooglePlusAuth
,但我只有80%的用户拥有电子邮件地址,因此会留下很多人拥有新帐户并需要支持才能手动关联尽可能地尝试,我无法找到人们使用social.pipeline.social_auth.associate_by_email
进行类似迁移的任何示例,但必须发生在很多人身上。
有什么想法吗?
答案 0 :(得分:1)
解决方案适用于python social auth 0.1.26
在python social auth的新版本(0.2。*)中,有 GoogleOpenIdConnect ,但它不能正常工作(至少我没有成功)。我的项目有一些遗产,所以我不能使用新版本的社交。
我写了自定义 GoogleOpenIdConnect 后端:
import datetime
from calendar import timegm
from jwt import InvalidTokenError, decode as jwt_decode
from social.backends.google import GoogleOAuth2
from social.exceptions import AuthTokenError
class GoogleOpenIdConnect(GoogleOAuth2):
name = 'google-openidconnect'
ACCESS_TOKEN_URL = 'https://www.googleapis.com/oauth2/v3/token'
DEFAULT_SCOPE = ['openid']
EXTRA_DATA = ['id_token', 'refresh_token', ('sub', 'id')]
ID_TOKEN_ISSUER = "accounts.google.com"
def user_data(self, access_token, *args, **kwargs):
return self.get_json(
'https://www.googleapis.com/plus/v1/people/me/openIdConnect',
params={'access_token': access_token, 'alt': 'json'}
)
def get_user_id(self, details, response):
return response['sub']
def request_access_token(self, *args, **kwargs):
"""
Retrieve the access token. Also, validate the id_token and
store it (temporarily).
"""
response = self.get_json(*args, **kwargs)
response['id_token_parsed'] = self.validate_and_return_id_token(response['id_token'])
return response
def validate_and_return_id_token(self, id_token):
"""
Validates the id_token according to the steps at
http://openid.net/specs/openid-connect-core-1_0.html#IDTokenValidation.
"""
try:
id_token = jwt_decode(id_token, verify=False)
except InvalidTokenError as err:
raise AuthTokenError(self, err)
# Verify the token was issued in the last 10 minutes
utc_timestamp = timegm(datetime.datetime.utcnow().utctimetuple())
if id_token['iat'] < (utc_timestamp - 600):
raise AuthTokenError(self, 'Incorrect id_token: iat')
return id_token
注意:
然后我创建了管道:
def social_user_google_backwards(strategy, uid, *args, **kwargs):
"""
Provide find user that was connect with google openID, but is logging with google oauth2
"""
result = social_user(strategy, uid, *args, **kwargs)
provider = strategy.backend.name
user = result.get('user')
if provider != 'google-openidconnect' or user is not None:
return result
openid_id = kwargs.get('response', {}).get('id_token_parsed', {}).get('openid_id')
if openid_id is None:
return result
social = _get_google_openid(strategy, openid_id)
if social is not None:
result.update({
'user': social.user,
'is_new': social.user is None,
'google_openid_social': social
})
return result
def _get_google_openid(strategy, openid_id):
social = strategy.storage.user.get_social_auth('openid', openid_id)
if social:
return social
return None
def associate_user(strategy, uid, user=None, social=None, *args, **kwargs):
result = social_associate_user(strategy, uid, user, social, *args, **kwargs)
google_openid_social = kwargs.pop('google_openid_social', None)
if google_openid_social is not None:
google_openid_social.delete()
return result
并更改了我的SOCIAL_AUTH_PIPELINE和AUTHENTICATION_BACKENDS设置:
AUTHENTICATION_BACKENDS = (
...
#'social.backends.open_id.OpenIdAuth' remove it
'social_extension.backends.google.GoogleOpenIdConnect', # add it
...
)
和
SOCIAL_AUTH_PIPELINE = (
'social.pipeline.social_auth.social_details',
'social.pipeline.social_auth.social_uid',
'social.pipeline.social_auth.auth_allowed',
# 'social.pipeline.social_auth.social_user', remove it
'social_extension.pipeline.social_user_google_backwards', # add it
'social.pipeline.user.get_username',
...
# 'social.pipeline.social_auth.associate_user', remove it
'social_extension.pipeline.associate_user', # add it
'social.pipeline.social_auth.load_extra_data',
...
)
