How do I wait for a my server to be updated? I am setting up my HttpServer and can get a response from my own status I pass in to the createContext handle with my GET method, but when I need to wait for the user (me) to click the Spotify auth link to redirect back to my server -
java.util.concurrent.ExecutionException: java.io.IOException: HTTP/1.1 header parser received no bytes
If I manually set the header String my GET will return the body fine. I've tried serverSocket and CompleteableFuture async(request, HttpResponse.BodyHandlers.ofString() ( from https://openjdk.java.net/groups/net/httpclient/recipes.html#asynchronousGet ) and still get the above exception.
In Chrome when I open http://localhost:8080 the Spotify code is there.
I'm thinking I need to loop the client.send(request, HttpResponse.BodyHandleers.ofString() until the server status code is updated, or set a wait time?
Here is the time I've been testing.
public static void startHttpServer() {
try {
server = HttpServer.create();
server.bind(new InetSocketAddress(8080), 0);
server.createContext("/", new HttpHandler() {
@Override
public void handle(HttpExchange exchange) throws IOException {
String query = /*"hey buddy, this is a Java server, wouldn't you know"; */exchange.getRequestURI().getQuery();
exchange.sendResponseHeaders(200, query.length());
exchange.getResponseBody().write(query.getBytes());
exchange.getResponseBody().close();
}
});
server.start();
System.out.println("*** Started server ***");
System.out.println("Use this link to request the access code:");
System.out.println("https://accounts.spotify.com/authorize?client_id=6edb9b1ac21042abacc6daaf0fbc4c4d&redirect_uri=http://localhost:8080&response_type=code");
} catch (IOException e) {
e.printStackTrace();
}
}
/*public static void getResponse() { // get the response from the server?!
try {
HttpClient client = HttpClient.newBuilder().connectTimeout(Duration.ofSeconds(15)).build();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("http://localhost:8080"))
.GET()
.build();
HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());
} catch (IOException | InterruptedException e) {
e.printStackTrace();
} finally {
server.stop(1);
}
}*/
public static CompletableFuture<String> get() {
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("http://localhost:8080"))
.GET()
.build();
return client.sendAsync(request, HttpResponse.BodyHandlers.ofString())
.thenApply(HttpResponse::body);
}
I am following a Hyperskill.org project. This is how the code should behave when this stage is complete.

use this link to request the access code:
https://accounts.spotify.com/authorize?client_id=a19ee7dbfda443b2a8150c9101bfd645&redirect_uri=http://localhost:8080&response_type=code
