Adds OAuth-based authentication to the [Spring Security plugin](http://grails.org/plugin/spring-security-core] using the [OAuth plugin](http://grails.org/plugin/oauth-scribe].

This plugin provides an OAuth realm that can easily be integrated into existing applications and a host of utility functions to make things like "log in with Twitter" almost trivial.

Installation

grails install-plugin spring-security-oauth

Usage

Install the plugin

grails install-plugin spring-security-oauth

then, follow Spring Security Core and OAuth plugins documentation.

Sample configuration for OAuth plugin:

oauth {
    debug = true
    providers {
        facebook {
            api = org.scribe.builder.api.FacebookApi
            key = 'oauth_facebook_key'
            secret = 'oauth_facebook_secret'
            successUri = '/oauth/facebook/success'
            failureUri = '/oauth/facebook/error'
            callback = "${baseURL}/oauth/facebook/callback"
        }
        twitter {
            api = org.scribe.builder.api.TwitterApi
            key = 'oauth_twitter_key'
            secret = 'oauth_twitter_secret'
            successUri = '/oauth/twitter/success'
            failureUri = '/oauth/twitter/error'
            callback = "${baseURL}/oauth/twitter/callback"
        }
        linkedin {
            api = org.scribe.builder.api.LinkedInApi
            key = 'oauth_linkedin_key'
            secret = 'oauth_linkedin_secret'
            successUri = '/oauth/linkedin/success'
            failureUri = '/oauth/linkedin/error'
            callback = "${baseURL}/oauth/linkedin/callback"
        }
        google {
            api = org.scribe.builder.api.GoogleApi
            key = 'oauth_google_key'
            secret = 'oauth_google_secret'
            successUri = '/oauth/google/success'
            failureUri = '/oauth/google/error'
            callback = "${baseURL}/oauth/google/callback"
            scope = 'https://www.googleapis.com/auth/userinfo.email'
        }
    }
}

Once you have an user domain and configured provider names, go with:

grails s2-init-oauth [domain-class-package] [oauthid-class-name]

Example:

grails s2-init-oauth com.yourapp OAuthID

that creates:

  • the domain class com.yourapp.OAuthID

  • the controller class com.yourapp.SpringSecurityOAuthController

  • the view springSecurityOAuth/askToLinkOrCreateAccount.gsp

Finally, add

static hasMany = [oAuthIDs: OAuthID]

to you user domain class.

In your view you can use the taglib exposed from this plugin and from OAuth plugin to create links and to know if the user is authenticated with a given provider:

<oauth:connect provider="twitter" id="twitter-connect-link">Twitter</oauth:connect>
<oauth:connect provider="facebook" id="facebook-connect-link">Facebook</oauth:connect>
<oauth:connect provider="google" id="google-connect-link">Google</oauth:connect>
<oauth:connect provider="yahoo" id="yahoo-connect-link">Yahoo</oauth:connect>
Logged with facebook? <s2o:ifLoggedInWith provider="facebook">yes</s2o:ifLoggedInWith><s2o:ifNotLoggedInWith provider="facebook">no</s2o:ifNotLoggedInWith>
Logged with twitter? <s2o:ifLoggedInWith provider="twitter">yes</s2o:ifLoggedInWith><s2o:ifNotLoggedInWith provider="twitter">no</s2o:ifNotLoggedInWith>
Logged with google? <s2o:ifLoggedInWith provider="google">yes</s2o:ifLoggedInWith><s2o:ifNotLoggedInWith provider="google">no</s2o:ifNotLoggedInWith>
Logged with linkedin? <s2o:ifLoggedInWith provider="linkedin">yes</s2o:ifLoggedInWith><s2o:ifNotLoggedInWith provider="linkedin">no</s2o:ifNotLoggedInWith>

That's it!
