Missing OAuth request token cookie error using tornado and TwitterMixin

I'm using tornado and the TwitterMixin and I use the following basic code:

class OauthTwitterHandler(BaseHandler, tornado.auth.TwitterMixin): 
    @tornado.web.asynchronous 
    def get(self): 
        if self.get_argument("oauth_token", None): 
            self.get_authenticated_user(self.async_callback(self._on_auth)) 
            return 
        self.authorize_redirect() 
    def _on_auth(self, user): 
        if not user: 
            raise tornado.web.HTTPError(500, "Twitter auth failed") 
        self.write(user) 
        self.finish()

For me it works very well but sometimes, users of my application get a 500 error which says: Missing OAuth request token cookie

I don't know if it comes from the browser or the twitter api callback configuration. I've looked through the tornado code and I don't understand why this error appears.

Solution

  • I found the solution !!

    It was due to my DNS.

    I didn't put the redirection for www.mydomain.com and mydomain.com so sometimes the cookie was set in www. and sometimes not then my server didn't check in the good place, didn't find the cookie and then send me a 500 error.
