Polymer.js + OAuth2

Question

Is there an example out there which describes how to implement an OAuth2 authentication in the frontend based on Polymer.js?

I just found some examples that describe the procedure for AJAX, which is also part of the Polymer element set. So how to go on ahead?

Answer 1

I found a git repo here which have demo. So you can take a look.

  <oauth-user></oauth-user>

  <polymer-element name="oauth-user">
    <template>
        <oauth-authenticator id="authenticator" client_id="282331888208-06mufq54k942624lv803nlm6kvlq76fr.apps.googleusercontent.com" scopes="https://www.googleapis.com/auth/userinfo.profile" on-authenticated="{{authenticated}}"></oauth-authenticator>
        <core-ajax auto id="ajax" url="{{url}}" headers="{{headers}}" handleAs="json" on-core-response="{{ajaxResponse}}"></core-ajax>
        <p>{{greeting}}</p>
    </template>
    <script>
        Polymer({
            url: '',
            greeting: '...',

            authenticated: function(event){
              var token = event.detail.token;
              this.headers = {'Authorization': 'Bearer ' + token};
              this.url = "https://www.googleapis.com/oauth2/v1/userinfo?alt=json";
            },

            ajaxResponse: function(event, response) {
              this.greeting = 'Hello ' + response.response.name + '!';
            }
        });
    </script>
  </polymer-element>

You can see there're event handler so you can redirect user or update screen. There're also a url to get user info.
