More about migration from async4.1.3 to http5

Hello,

 

Just three more questions:

 

1.       Is this the way to set a byte array to the RequestBuilder’s entity
(using a org.apache.http.nio.entity.NByteArrayEntity)?

 

org.apache.hc.client5.http.classic.methods.RequestBuilder.RequestBuilder rb
= RequestBuilder.post(uri);

org.apache.http.nio.entity.NByteArrayEntity nbae = new
NByteArrayEntity(requestBody);

nbae.setContentType(contentType);

rb.setEntity(nbae);

return rb.build();

 

 

2.       With the Async client, in order to send an async request to be
consumed for an AsyncConsumer:

 

       HttpRequest httpRequest    = this.createPostRequest(uri,
responseTimeout);

HttpAsyncResponseConsumer<Void> harc = new ServerHttpResponse(…);

this.objHttp.getAsyncHttpClient().execute(new
BasicAsyncRequestProducer(this.createHttpHost(uri), httpRequest), harc,
null);

 

What request producer must I use now? I can’t find anyone that accomplish
with (
<eclipse-javadoc:%E2%98%82=vpfw/web%5C/WEB-INF%5C/lib%5C/httpcore5-5.0-beta3

.jar%3Corg.apache.hc.core5.http> http.Request)

 

 

3.       Regarding to the HttpAsyncResponseConsumer, what is the equivalent
interface in Http5 with the methods ‘responseReceived’, ‘consumeContent’ and
‘responseCompleted’?

 

 

I have been looking at the examples, but I couldn’t find anything similar.

 

Thanks,

 

Joan.

Do not use classic request builder. Use AsyncRequestBuilder instead.

Use AsyncRequestBuilder.

You might find AbstractBinResponseConsumer and
AbstractCharResponseConsumer useful as base classes for custom response
consumers.

This is a whole bunch of examples of all sorts.
