A Basic Grails App with Authentication

This example creates a basic camera inventory application with Grails and adds authentication with Okta. See the corresponding blog posts for more info:

• Build Server Side Authentication in Grails with OAuth 2.0 and Okta - creates initial application and adds OAuth 2.0 support
• Build a Basic CRUD Application with Grails and Okta - adds additional endpoints and secures them with annotations

Prerequisites:

• Java 8
• Grails

Okta has Authentication and User Management APIs that reduce development time with instant-on, scalable user infrastructure. Okta's intuitive API and expert support make it easy for developers to authenticate, manage, and secure users and roles in any application.

Getting Started

To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/okta-grails-example.git
cd okta-grails-example

This will get a copy of the project installed locally. You can run the application with:

grails run-app

Setup Okta

Log in to your Okta Developer account (or # if you don’t have an account) and navigate to Applications > Add Application. Click Single-Page App, click Next, and give the app a name you’ll remember. Click Done.

Server Configuration

Open grails-app/conf/application.yml and replace {yourOktaDomain}, <Okta Client ID>, and <Okta Client Secret> in the following code block.

okta:
    api_key: '<Okta Client ID>'         
    api_secret: '<Okta Client Secret>'
    userInfoUrl: 'https://{yourOktaDomain}.com/oauth2/default/v1/userinfo'
    authorizeUrl: 'https://{yourOktaDomain}.com/oauth2/default/v1/authorize'
    tokenUrl: 'https://{yourOktaDomain}.com/oauth2/default/v1/token'
    scopes: 'email profile openid'

NOTE: The value of {yourOktaDomain} should be something like dev-123456.oktapreview. Make sure you don't include -admin in the value!
