Golang + Okta Hosted Login Example

This example shows you how to use Golang to login to your application with an Okta Hosted Login page. The login is achieved through the authorization code flow, where the user is redirected to the Okta-Hosted login page. After the user authenticates they are redirected back to the application with an access code that is then exchanged for an access token.

Prerequisites

Before running this sample, you will need the following:

• An Okta Developer Account, you can sign up for one at https://developer.okta.com/signup/.
• An Okta Application, configured for Web mode. This is done from the Okta Developer Console and you can find instructions here. When following the wizard, use the default properties. They are are designed to work with our sample applications.

Running This Example

To run this application, you first need to clone this repo and then enter into this directory:

git clone https://github.com/okta/samples-golang.git
cd samples-golang/okta-hosted-login

Then install dependencies:

go get

You also need to gather the following information from the Okta Developer Console:

• Client ID and Client Secret - These can be found on the "General" tab of the Web application that you created earlier in the Okta Developer Console.
• Issuer - This is the URL of the authorization server that will perform authentication. All Developer Accounts have a "default" authorization server. The issuer is a combination of your Org URL (found in the upper right of the console home page) and /oauth2/default. For example, https://dev-1234.oktapreview.com/oauth2/default.

Now that you have the information from your organization that you need, copy the .env.dist to .env and fill in the information you gathered.

CLIENT_ID={clientId}
CLIENT_SECRET={clientSecret}
ISSUER=https://{yourOktaDomain}/oauth2/default

Now start the app server:

go run main.go

Now navigate to http://localhost:8080 in your browser.

If you see a home page that prompts you to login, then things are working! Clicking the Log in button will redirect you to the Okta hosted sign-in page.

You can login with the same account that you created when signing up for your Developer Org, or you can use a known username and password from your Okta Directory.

Note: If you are currently using your Developer Console, you already have a Single Sign-On (SSO) session for your Org. You will be automatically logged into your application as the same user that is using the Developer Console. You may want to use an incognito tab to test the flow from a blank slate.
