[keycloak-user] Library for external HTTP calls.

[Dmitry Telegin]

Hello Marco,

Keycloak ships Apache HttpClient, and offers HttpClientSpi for obtaining a preconfigured HttpClient instance:

HttpClientProvider provider = session.getProvider(HttpClientProvider.class);

InputStream is = provider.get("http://...");
// or
in rc = provider.postText("http://...", "foo=bar");
// or
HttpClient httpClient = provider.getHttpClient();

See org.keycloak.connections.httpclient.DefaultHttpClientFactory::lazyInit() for the list of configurable options.

Cheers,
