Hi again,
I have just dig deeper in the source code, and I found the way to extract
the *service URL*, here how it can be done in CAS 5.2.0-RC4 (I am too lazy
to test it in other version, please change the code accordingly)
public class CustomAuthenticationHandler implements AuthenticationHandler {
protected PrincipalFactory principalFactory = new
DefaultPrincipalFactory();
@Autowired
PropertiesConfiguration propertiesConfiguration;
private transient Logger logger =
LoggerFactory.getLogger(this.getClass());
@Override
public HandlerResult authenticate(Credential credential) throws
GeneralSecurityException, PreventedException {
UsernamePasswordCredential usernamePasswordCredential =
(UsernamePasswordCredential) credential;
// Here I would like to have access to the encoded address
final RequestContext context =
RequestContextHolder.getRequestContext();
final WebApplicationService service = WebUtils.getService(context);
//WebUtils use the CAS one
*String theUrlThatYouNeed = service.getId();*
//Of course you need to extract the hostname from the url
}
*Additional Info:*
I will also shows you the steps I acquire this information, so you might
reference if you want.
1) I search all types of AuthenticationHandler and see if any of them is
using the serviceParam url
2) I sumble accross this class *YubiKeyAuthenticationHandler *(actually, I
don't know what this handler does... but it doesn't matter much)
3) I see that it uses RequestContext, so I immediate see what this class
does (Since I know request context -> GET parameter -> service parameter ->
goal)
4) I see that with RequestContext, I can get WebApplicationService and
Service
https://github.com/apereo/cas/blob/master/api/cas-server-core-api-authentication/src/main/java/org/apereo/cas/authentication/principal/Service.java
5) I see this line *final String serviceUrl =
URLDecoder.decode(service.getId(), StandardCharsets.UTF_8.name());*
6) hence I know the I can use service.getId() to get the service URL
Hope this helps you!
