Solved GET, POST, and PUT (OAuth client) libraries

I've worked with org.apache.httpcomponents's HttpClient before, but apparantly this library "is too big", and it's useless have I been told. So what do you suggest I use in order to make GET, POST, and PUT requests with headers, etc...?

 

All I want to be able to do is to send JSON Http GET, POST, and PUT requests which includes a header, and JSON-encoded dictionary as payload

The standard java HttpURLConnection class can do all of that with ease.

Code:java

URL url = new URL("[URL]https://www.helloworld.com[/URL]"); // obviously without the "URL" thing, the forums are just screwing with it.
HttpURLConnection httpConnection = (HttpURLConnection) url.openConnection();
// Setting the content-type (all json services may not require this, but I know Mojang's do)
httpConnection.setRequestProperty("content-type", "application/json");
// Setting the request method
httpConnection.setRequestMethod("POST");
// Just tell the connection that we actually wan't to receive something back from this request.
httpConnection.setDoOutput(true);
// Method of writing to the connection, anything capable of writing to an output stream works.
// Just be mindful to properly close the outputstream when you're done (either in a finally or try with resources block)
OutputStreamWriter streamWriter = new OutputStreamWriter(httpConnection.getOutputStream());
streamWriter.write("Hello World!");
// Checking the response code, so we know no error has occurred.
if (httpConnection.getResponseCode() == 200) {
    // Again, anything capable of reading from an inputstream will work here.
    // And as always, close properly.
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(httpConnection.getInputStream()));
    System.out.println("Response: " + bufferedReader.readLine());
}

Yeah, and don't forget to do it async.

 

@AlvinB
streamWriter.write("Hello World!");

So basically instead of this, I would put my JSON object?

 

Yeh, JsonObject#toString() am I right?

 

@DoggyCode™
Yep.

 

Works perfectly. Thanks!
