![]() ![]() JavaFX Http Request / Response Inspector App You will see several other examples of constructing a HttpRequest throughout this article. POST(BodyPublishers.ofFile(Paths.get("file.json"))) header("Content-Type", "application/json") HttpRequest request = HttpRequest.newBuilder() The HttpRequest also utilizes a builder to configure and construct a reusable instance, again, here is the example from the OpenJDK docs. authenticator(Authenticator.getDefault()) proxy(ProxySelector.of(new InetSocketAddress("", 8080))) HttpClient client = HttpClient.newBuilder() However, the HttpClient utilizes the powerful builder pattern for creating HttpClient instances that require special configuration such as the following excerpt from the OpenJDK docs that introduces the Http Client API. In the examples for this article I am reusing the same HttpClient instance which I construct with the default creational method of HttpClient#newHttpClient as shown in step one above. There is a generalized workflow that occurs when using the Http Client API for the familar request / response cyclical nature of HTTP network calls that is as follows.ġ) Build a HttpClient instance HttpClient client = HttpClient.newHttpClient() Ģ) Build a HttpRequest instance HttpRequest request = HttpRequest.newBuilder(URI.create(""))ģ) Use the HttpClient instance to initiate sending the request to the target endpoint for the http request HttpResponse response = nd(request, BodyHandlers.ofString()) Ĥ) Handle the response as it is returned ("Hey look, an http response " + response.body()) HttpResponse represents the Http Response to a Http Request.HttpRequest represents the Http Request being made and send by HttpClient. ![]() HttpClient is the moderator which wraps all requests and responses.These are the key types to be familar with in the Http Client API: The Http Client API has an intuitive and modern API allowing for both synchronous and asynchronous code flows along with sensible defaults like first trying HTTP 2 then failing back to HTTP 1.1. The new Http Client API introduced in Java 11 lives in the package and is a revamped approach to handling HTTP based network communication. Introducing the Key HTTP Client API Classes ![]()
