grails-spring-security-oauth-google Build Status

Google extension for Grails Spring Security OAuth plugin

Installation

Add the following plugin definition to your BuildConfig:

// ...
plugins {
  // ...
  compile ':spring-security-oauth:2.0.2'
  compile ':spring-security-oauth-google:0.2'
  // ...
}

Usage

Add to your Config.groovy:

def appName = grails.util.Metadata.current.'app.name'
def baseURL = grails.serverURL ?: "http://127.0.0.1:${System.getProperty('server.port', '8080')}/${appName}"
oauth {
  // ...
  providers {
    // ...

    // Choose only one "google" block

    // for Google OAuth 1.0 DEPRECATED from Google
    // it uses api class provided from Scribe library
    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'
    }

    // for Google OAuth 2.0
    google {
      api = org.grails.plugin.springsecurity.oauth.GoogleApi20
      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.profile https://www.googleapis.com/auth/userinfo.email'
    }
    // ...
  }
}

Add the following to Config.groovy if you want to use Secured annotations together with Spring security. All references to InterceptUrlMap should be removed.

grails.plugin.springsecurity.securityConfigType = 'Annotation'
grails.plugin.springsecurity.controllerAnnotations.staticRules = [
        '/':                              ['permitAll'],
        '/index':                         ['permitAll'],
        '/index.gsp':                     ['permitAll'],
        '/login/**':                      ['permitAll'],
        '/assets/**':                     ['permitAll'],
        '/**/js/**':                      ['permitAll'],
        '/**/css/**':                     ['permitAll'],
        '/**/images/**':                  ['permitAll'],
        '/**/favicon.ico':                ['permitAll'],
        '/oauth/**':                      ['permitAll'],
        '/springSecurityOAuth/**':        ['permitAll']
]

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="google" id="google-connect-link">Google</oauth:connect>

Logged with google?
<s2o:ifLoggedInWith provider="google">yes</s2o:ifLoggedInWith>
<s2o:ifNotLoggedInWith provider="google">no</s2o:ifNotLoggedInWith>

You can look at bagage's sample app.
