google app engine - GAE weapp2 Access-Control-Allow-Origin Error -

I get this error when using webapp2 user authentication

Before the redirection I have access header How do I add?

Redirect code: self.redirect (Users.create_login_url (self.request.uri))

Code:

 < Code> class certify (webapp2.RequestHandler): def mill (auto): user = users.get_current_user () cookie_value = self.request.cookies.get ('user') if user == cookie_value and user! = None: self.response.headers ['content type'] = 'text / plain' itself .response.write ('success') Other: self request. Title ['access-control-permission-origin'] = '*' self.redirect (users.create_login_url (self.request.uri))  

  DEF redirect (self, Yuri, permanent = fault, Ebert = Fell, code = none, body = none)  

and

  DEF redirect (Yuri, permanent = fault, abot = fault, code = none, body = none, request = none, feedback = none)  

So, I think you should call the other (if You want to pass the response object):

return webapp2.redirect (users.create_login_url (self.request.uri), correct, wrong, none, none, none , Self.response)
