Rauth __attrs__与OAuth2Service.get_session

Question

遇到Rauth（或Reqeuests）Oauth2会话使用问题。希望下面的代码和错误是有道理的。

谢谢， 史蒂夫

错误讯息： 'OAuth2Session' object has no attribute '__attrs__'

代码：

self.auth_service = OAuth2Service(
  name=self.PARSER_NAME,
  client_id=self.CLIENT_ID,
  client_secret=self.CLIENT_SECRET,
  access_token_url=self.ACCESS_TOKEN_URL,
  authorize_url=self.AUTHORIZE_URL,
  base_url=self.BASE_URL,
)   
    session = self.auth_service.get_session(token=token_data["access_token"])
    # I tried this as an alternate way to get the session with same results
    #session = OAuth2Session(self.CLIENT_ID, self.CLIENT_SECRET, access_token=token_data["access_token"])
    self.request.session['oauth_session'] = session 

错误：

看起来它追溯到请求会话：

/Library/Python/2.7/site-packages/requests/sessions.py in __getstate__
    return dict((attr, getattr(self, attr, None)) for attr in self.__attrs__)

@maxcountryman帮助我在GitHub问题跟踪器上回答了这个问题。从1.1.0到1.2.3的请求的简单更新是修复。我猜pip install rauth --upgrade没有触发请求更新
