Error validating wap authentication token
Google's OAuth 2.0 APIs can be used for both authentication and authorization.
This document describes our OAuth 2.0 implementation for authentication, which conforms to the Open ID Connect specification, and is Open ID Certified.
The following code demonstrates confirming the session tokens that you created in Step 1: // Ensure that there is no request forgery going on, and that the user // sending us this connect request is the user that was supposed to. request.query Params("state").equals( request.session().attribute("state"))) # Ensure that the request is not a forgery and that the user sending # this connect request is the expected user. = session['state']: response = make_response(json.dumps('Invalid state parameter.'), 401) response.headers['Content-Type'] = 'application/json' return response POST /oauth2/v4/token HTTP/1.1 Host: application/x-www-form-urlencoded code=4/P7q7W91a-o Ms Ce Lv Ia Qm6b Trgtp7& client_id=8819981768googleusercontent.com& client_secret=& redirect_uri=https://oauth2-login-demo.example.com/code& grant_type=authorization_code Note: There is a limit to the number of tokens per Google user account, and any authentication request above this limit might quietly invalidate an outstanding refresh token. An ID Token is a JWT (JSON Web Token), that is, a cryptographically signed Base64-encoded JSON object.
Normally, it is critical that you validate an ID token before you use it, but since you are communicating directly with Google over an intermediary-free HTTPS channel and using your client secret to authenticate yourself to Google, you can be confident that the token you receive really comes from Google and is valid.
An ID token's payload An ID token is a JSON object containing a set of name/value pairs.
This round-trip verification helps to ensure that the user, not a malicious script, is making the request.Provides validation that the access token is tied to the identity token.If the ID token is issued with an access token in the server flow, this is always included.Make sure you set up your app in the API Console to enable it to use these protocols and authenticate your users.When a user tries to log in with Google, you need to: https://accounts.google.com/o/oauth2/v2/auth?
