Making an HTTP GET request

In this recipe, we will look at using the JDK 11 HTTP Client API to make a GET request to http://httpbin.org/get.

How to do it...

1. Create an instance of java.net.http.HttpClient using its builder, java.net.http.HttpClient.Builder:

        HttpClient client =HttpClient.newBuilder().build();

2. Create an instance of java.net.http.HttpRequest using its builder, java.net.http.HttpRequest.Builder. The requested URL should be provided as an instance of java.net.URI:

        HttpRequest request =HttpRequest
                    .newBuilder(newURI("http://httpbin.org/get"))
                    .GET()
                    .version(HttpClient.Version.HTTP_1_1)
                    .build();

3. Send the HTTP request using the send API of java.net.http.HttpClient. This API takes an instance of java.net.http.HttpRequest and an implementation of java.net.http.HttpResponse.BodyHandler:

        HttpResponse<String> response = client.send(request,
                             HttpResponse...
