[FIXED] HttpRequest DELETE with body

Issue

I have to submit an http DELETE request containing a body. I know how I can do it, but in my case it uses java.net.http.HttpRequest. Unfortunately, this component only allows submission of BodyPublisher to PUT and POST requests.

My question is, is there any way to use HttpRequest for the problematic DELETE request?

Solution

You can use the HttpRequest.Builder::method that takes two arguments:

HttpClient client = HttpClient.newBuilder().proxy(HttpClient.Builder.NO_PROXY).build();
HttpServer server = HttpServer.create();
server.bind(new InetSocketAddress(InetAddress.getLoopbackAddress(), 0), 0);
server.createContext("/test/", new HttpHandler() {
    @Override
    public void handle(HttpExchange exchange) throws IOException {
        byte[] bytes = exchange.getRequestBody().readAllBytes();
        exchange.sendResponseHeaders(200, bytes.length == 0 ? -1 : bytes.length);
        try (OutputStream os = exchange.getResponseBody()) {
            os.write(bytes);
        }
    }
});
server.start();
try {
    HttpRequest request = HttpRequest.newBuilder()
            .uri(new URI("http", null,
                    server.getAddress().getHostString(),
                    server.getAddress().getPort(),
                    "/test/test", null, null))
            .method("DELETE", HttpRequest.BodyPublishers.ofString("hahaha...")).build();
    var resp = client.send(request, HttpResponse.BodyHandlers.ofString());
    System.out.println(resp);
    System.out.println(resp.body());
} finally {
    server.stop(0);
}
