jQuery plugin for doing Oauth2 login in a Cordova App

This jquery plugin can be used to perform Oauth2 login in Cordova app, it uses Cordova In-App-Browser to perform Oauth2 login flow and returns access_token or error in callback, along with actual response from the Oauth2 service.

Features

• Supports Oauth2 authorization code grant flow (server explicit)

• Supports Oauth2 implicit grant flow (client implicit)

  [Implicit grant is recomended for Cordova apps since it does not require app to store client_secret]

Usage

    $.oauth2({
        auth_url: '',           // required
        response_type: '',      // required  - "code"/"token"
        token_url: '',          // required for response_type ="code"
        logout_url: '',         // recommended if available
        client_id: '',          // required
        client_secret: '',      // required for response_type ="code"
        redirect_uri: '',       // required - any dummy url http://www.yourcompany.com
        other_params: {}         // optional params object for scope, state, ...
    }, function(token, response){
        // do something with token or response
    }, function(error, response){
        // do something with error object
    }); 

Example Oauth2 Calls:

1) Google Oauth2 (Authorization code grant): This example show how to make Google Oauth2 call, notice the scope parameter is sepcified in the other_params option as an object. The first callback function will return the access_token which can be passed to another function to save and make other API calls. The second callback function handle any errors.

    $.oauth2({
        auth_url: 'https://accounts.google.com/o/oauth2/auth',
        response_type: 'code',
        token_url: 'https://accounts.google.com/o/oauth2/token',
        logout_url: 'https://accounts.google.com/logout',
        client_id: 'CLIENT-ID-FROM-GOOGLE',
        client_secret: 'CLIENT-SECRET-FROM-GOOGLE',
        redirect_uri: 'http://www.yourwebsite.com/oauth2callback',
        other_params: {scope:'profile'}
    }, function(token, response){
        makeAPICalls(token);
    }, function(error, response){
        alert(error);
    }); 

2) Facebook Oauth2 (Implicit grant): Notice that token_url and client_secret is not required for Implicit grant and logout_url is not specified since facebook does not not have a logout url. Facebook also required a special display parameter to be passed in the URL, this is specified in the other_params.

    $.oauth2({
        auth_url: 'https://www.facebook.com/dialog/oauth',
        response_type: 'token',
        client_id: 'CLIENT-ID-FROM-FACEBOOK',
        redirect_uri: 'http://www.yourwebsite.com/oauth2callback',
        other_params: {scope: 'basic_info', display: 'popup'}
    }, function(token, response){
        makeAPICalls(token);
    }, function(error, response){
        alert(error);
    });
