Vert.x includes an HttpClient and associated code for interacting with HTTP protocols, obviously this can be used to write client applications or in situations where we might use a reference from service discovery.

This is a very short post which is just mean’t to demonstrate the client capability which will be used in the next post (Service discovery with Vert.x).

HttpClient client = vertx.createHttpClient();
client.getNow(8080, "localhost", "/hello", response ->
{
   response.bodyHandler(
      body -> 
         System.out.println(body.toString()));
});

The HttpClient gives us get, post, head etc. the Now postfixed named methods tend to be simpler syntax including the supply of callback and are composable using fluent style syntax.
