ContentGrid HAL Forms Client

Context

This is a minimal HAL and HAL-FORMS client, to be used with integration tests.

Usage

var halFormsClient = HalFormsClient.builder().restClient(restClient).build();

var orgs = halFormsClient.follow(HalLink.from(URI.create("http://api.contentgrid.test/orgs")));
var myOrg = halFormsClient.requestDefaultTemplate(orgs)
        .properties(Map.of("display_name", "test"))
        .execute().toHalDocument();

var projects = halFormsClient.follow(myOrg.getRequiredLink("projects"));
var testProject = halFormsClient.requestDefaultTemplate(projects)
        .properties(Map.of("name", "test"))
        .execute().toHalDocument();

Possible improvements

• More explicit support for OAuth2 clients
• Use Spring HATEOAS concepts: RepresentationModel<T>
• Use Spring HATEOAS / Traverson concepts: LinkRelation, LinkDiscoverer, ...
• Base internals on RestOperations to improve testability, potentially using RestOperationsAdapter
• Add support to automatically follow redirects (HTTP 302)
• Let DefaultHalFormsClient extend DefaultHalClient to avoid duplication (possibly via ServiceLoader)
