I'm just playing and testing a bit with the Restlet Client Api 2.2, but I don't get a non-blocking asynchronous request with a callback to work. I already have googled extensively but really not found an answer to a (working) non-blocking solution.
I have the following two approaches:
Approach 1 ( Client - Request ):
Client c = new Client(Protocol.HTTP);
Request r = new Request(Method.GET, url);
System.out.println("START1");
c.handle(r, new Uniform() {
@Override
public void handle(Request request, Response response) {
int statusCode = response.getStatus().getCode();
System.out.println(statusCode);
}
});
System.out.println("START2");
Approach 2 ( ClientResource - setOnResponse() - get() ):
ClientResource cr = new ClientResource(url);
cr.setOnResponse(new Uniform() {
@Override
public void handle(Request request, Response response) {
int statusCode = response.getStatus().getCode();
System.out.println(statusCode);
}
});
System.out.println("START1");
cr.get();
System.out.println("START2");
The Console-Output for both approaches is always:
START1
Starting the internal HTTP client
SOME WAITING HERE
200
START2
Can anyone give me a hint to make one of these approaches non-blocking? Is that at all possible with the Restlet API? What am I missing, do I need another connector or must I define a seperate thread for the request myself?
