RESTlet + JAX-RS身份验证中间件

Question

I'm making a backend API using RESTlet and JAX-RS on app engine. I'd like to make a method that is called before each request to check whether the user is authenticated (has to make a query to an external API via HTTP) and then continue or stop depending.

How could I do this?

Thanks, Daniel

Turns out to be very simple.

Create a subclass of Authenticator ( http://restlet.com/technical-resources/restlet-framework/javadocs/2.3/jse/api/org/restlet/security/Authenticator.html?is-external=true ) and implement authenticate() with custom authentication and any other functions that are needed.

For example,

public class MyAuthenticator extends Authenticator {

public MyAuthenticator(Context context) {
    super(context);
}

@Override
protected boolean authenticate(Request request, Response response) {
    // do your custom authentication here and return true or false depending on result
}
