get(); // the response: System.out.println(response.body().get().title); [ full code on GitHub ] Third-party Java HTTP client libraries If the built-in clients don't work for you, don't worry! There are many libraries that can be included in your project that will do the job just fine.
Apache HttpClient The Apache Software Foundation 's HTTP clients have been around for quite a while.
They are widely used and are the basis for a lot of high-level philippines mobile number example libraries. The history is a bit confusing. The old Commons HttpClient client is no longer developed, and the new version ( also called HttpClient) is part of the HttpComponents project . Version 5.0 of the library, released in early 2020, adds support for the HTTP/2 protocol.
It also supports both synchronous and asynchronous requests. Overall, the API is pretty low-level; you have to implement a lot of it yourself.
The code below calls the NASA API. It doesn't seem too hard to use, but I skipped a lot of the error handling that you'd want to see in production code, and I had to add some Jackson code to parse the JSON response.
You might also want to set up a logging framework to avoid warnings on the standard output stream (not a problem per se, but it's just a bit annoying). Anyway, here's the code: Java Copy the code ObjectMapper mapper = new ObjectMapper(); try (CloseableHttpClient client = HttpClients.createDefault()) { HttpGet request = new HttpGe
nasa.gov/planetary/apod?api_key=DEMO_KEY"); APOD response = client.
execute(request, httpResponse -> mapper.readValue(httpResponse.getEntity().getContent(), APOD.class)); System.out.println(response.title); } [ full code on GitHub ] Apache provides several other examples regarding synchronous and asynchronous requests . OkHttp OkHttp is a Square HTTP client that offers many useful built-in features, such as automatic GZIP handling, response caching, and retrying or falling back to alternate hosts on network errors, as well as support for HTTP/2 and WebSockets.
