How to use the library

Kotlin

• Step 1: Load Client Configuration

 ClientConfiguration.
               .with()
               .client("<your-client-id>",
               "<your-redirect-uri>",
               "<your-secret>")
               .issuer("<issuer-url>")

• Step 2: Make an Authentication Request

AuthenticationRequestBuilder()
                        .basic()
                        .build()
                        .andRedirect(response);

• Step 3: Exchange Code for access token and id token

val user = OpenIdConnectCallBackInterceptor(httpServletRequest)
                .extractCode()
                .exchangeCodeForTokens()
                .extractAuthenticatedUserInfo();

Java

• Step 1: Load Client Configuration

 ClientConfiguration.INSTANCE
               .with()
               .client("<your-client-id>",
               "<your-redirect-uri>",
               "<your-secret>")
               .issuer("<issuer-url>")

• Step 2: Make an Authentication Request

new AuthenticationRequestBuilder()
                        .basic()
                        .build()
                        .andRedirect(response);

• Step 3: Exchange Code for access token and id token

AuthenticatedUser user = new OpenIdConnectCallBackInterceptor(httpServletRequest)
                .extractCode(null)
                .exchangeCodeForTokens()
                .extractAuthenticatedUserInfo(null);
