Ajax and non-Ajax calls with OIDC in Helidon SE: A Comprehensive Guide

Are you tired of struggling with implementing OIDC in your Helidon SE application? Do you want to learn how to make Ajax and non-Ajax calls securely using OIDC? Look no further! In this article, we’ll take you on a step-by-step journey to master OIDC in Helidon SE, covering both Ajax and non-Ajax calls.

What is OIDC?

OIDC (OpenID Connect) is an extension of the OAuth 2.0 protocol that provides authentication and authorization for web applications. It’s a widely adopted standard for secure authentication and authorization, allowing users to access multiple applications with a single set of credentials.

Why Use OIDC in Helidon SE?

Helidon SE is a lightweight, open-source framework for building microservices-based applications. By using OIDC in Helidon SE, you can:

• Implement secure authentication and authorization
• Reduce the complexity of authentication and authorization logic
• Integrate with external identity providers
• Improve user experience with single sign-on (SSO)

Setting up OIDC in Helidon SE

To get started with OIDC in Helidon SE, you’ll need to:

1. Add the `helidon-oidc` dependency to your `pom.xml` file:

   <dependency>
     <groupId>io.helidon</groupId>
     <artifactId>helidon-oidc</artifactId>
   </dependency>

2. Configure OIDC in your `application.yaml` file:

   oidc:
     providers:
       - id: my-provider
         issuer-uri: https://my-issuer.com
         client-id: my-client-id
         client-secret: my-client-secret

3. Inject the `OidcProvider` instance in your application:

   @Inject
   @Config("oidc.providers.my-provider")
   OidcProvider oidcProvider;

Ajax Calls with OIDC in Helidon SE

To make Ajax calls with OIDC in Helidon SE, you’ll need to:

1. Obtain an access token using the `OidcProvider` instance:

   String accessToken = oidcProvider.getAccessToken();

2. Set the access token in the `Authorization` header of your Ajax request:

   XMLHttpRequest xhr = new XMLHttpRequest();
   xhr.open('GET', '/protected-resource', true);
   xhr.setRequestHeader('Authorization', 'Bearer ' + accessToken);
   xhr.send();

3. Handle the response from the protected resource:

   xhr.onload = function() {
     if (xhr.status === 200) {
       console.log('Response: ' + xhr.responseText);
     } else {
       console.error('Error: ' + xhr.status);
     }
   }

Non-Ajax Calls with OIDC in Helidon SE

To make non-Ajax calls with OIDC in Helidon SE, you’ll need to:

1. Obtain an access token using the `OidcProvider` instance:

   String accessToken = oidcProvider.getAccessToken();

2. Pass the access token as a query parameter or in the request body:

   @GET
   @Path("/protected-resource")
   public Response getProtectedResource(@QueryParam("access_token") String accessToken) {
     // Verify the access token and authenticate the user
     // ...
   }

3. Verify the access token and authenticate the user:

   if (oidcProvider.verifyAccessToken(accessToken)) {
     // Authenticate the user and return the protected resource
     // ...
   } else {
     // Return an error response
     // ...
   }

OIDC Flow in Helidon SE

The following table illustrates the OIDC flow in Helidon SE:

Step	Description
1	User requests access to a protected resource
2	Helidon SE redirects the user to the OIDC provider
3	OIDC provider authenticates the user and redirects back to Helidon SE
4	Helidon SE exchanges the authorization code for an access token
5	User requests access to the protected resource with the access token
6	Helidon SE verifies the access token and authenticates the user
7	Helidon SE returns the protected resource to the user

Best Practices for OIDC in Helidon SE

To ensure secure and efficient OIDC implementation in Helidon SE, follow these best practices:

• Use a secure connection (HTTPS) for OIDC communication
• Use a secure secret key for the OIDC provider
• Implement token refresh and revocation mechanisms
• Use a short-lived access token and a long-lived refresh token
• Implement rate limiting and IP blocking for OIDC requests

By following this comprehensive guide, you’ll be able to implement OIDC in your Helidon SE application with ease, securing both Ajax and non-Ajax calls. Remember to follow best practices and troubleshoot common issues to ensure a seamless user experience.

Happy coding!
