Hello I am trying to look for a simple example in AKKA - Java to create a HTTP Client un an Actor. So far I am able to create a request and get the response Http Entity. I need to migrate it to an actor , so I can call multiple actors in parallel with a time out.
final ActorSystem system = ActorSystem.create();
final Materializer materializer = ActorMaterializer.create(system);
final List<HttpRequest> httpRequests = Arrays.asList(
HttpRequest.create(url) // Content-Encoding: gzip in respons
);
Unmarshaller<ByteString, BitTweet> unmarshal = Jackson.byteStringUnmarshaller(BitTweet.class);
JsonEntityStreamingSupport support = EntityStreamingSupport.json();
final Http http = Http.get(system);
final Function<HttpResponse, HttpResponse> decodeResponse = response -> {
// Pick the right coder
final Coder coder;
if (HttpEncodings.gzip().equals(response.encoding())) {
coder = Coder.Gzip;
} else if (HttpEncodings.deflate().equals(response.encoding())) {
coder = Coder.Deflate;
} else {
coder = Coder.NoCoding;
}
// Decode the entity
return coder.decodeMessage(response);
};
List<CompletableFuture<HttpResponse>> futureResponses = httpRequests.stream()
.map(req -> http.singleRequest(req, materializer)
.thenApply(decodeResponse))
.map(CompletionStage::toCompletableFuture)
.collect(Collectors.toList());
for (CompletableFuture<HttpResponse> futureResponse : futureResponses) {
final HttpResponse httpResponse = futureResponse.get();
system.log().info("response is: " + httpResponse.entity()
.toStrict(1, materializer)
.toCompletableFuture()
.get());
HttpEntity.Strict entity_ = HttpEntities.create(ContentTypes.APPLICATION_JSON, httpResponse.entity().toString());
Source<BitTweet, Object> BitTweet =
entity_.getDataBytes()
.via(support.framingDecoder()) // apply JSON framing
.mapAsync(1, // unmarshal each element
bs -> unmarshal.unmarshal(bs, materializer)
);
