Refer to the documentation to learn how to use servers and handlers.

✨ Features

✔️ Complicated tasks made easy

Simplified exchange methods for:

• Parsing GET/POST requests, including multipart/form-data support.
• Accessing cookies.
• Sending byte arrays, strings, and files to clients.
• Sending gzip compressed responses.

SimpleHttpHandler handler = new SimpleHttpHandler(){
    @Override
    public void handle(SimpleHttpExchange exchange){
        Map POST = exchange.getPostMap();
        MultipartFormData form = exchange.getMultipartFormData();
        Record record = form.getRecord("record");
        FileRecord file = form.getRecord("file").asFile();
        exchange.send(new File("OK.png"), true);
    }
};

⭐ More Features

Features not included with a regular HTTP server:

• Cookies
• Sessions
• Multithreaded Servers

SimpleHttpServer server = new SimpleHttpServer(8080);
server.setHttpSessionHandler(new HttpSessionHandler());
SimpleHttpHandler handler = new SimpleHttpHandler(){
    @Override
    public void handle(SimpleHttpExchange exchange){
        HttpSession session = server.getHttpSession(exchange);
        String session_id = session.getSessionID();
        Map<String,String> cookies = exchange.getCookies();
        exchange.close();
    }
};

🌐 Simplified Handlers

Simple and extensible request handlers:

• Redirect Handler
• Predicate Handler
• Root / Handler
• File Handler
• Server-Sent-Events (SSE) Handler
• Temporary Handler
• Timeout Handler
• Throttled Handler

RedirectHandler redirect = new RedirectHandler("https://github.com/");
FileHandler fileHandler = new FileHandler();
fileHandler.addFile(new File("index.html"));
fileHandler.addDirectory(new File("/site"));
SSEHandler SSE = new SSEHandler();
SSE.push("Server sent events!");
ThrottledHandler throttled = new ThrottledHandler(new ServerExchangeThrottler(), new HttpHandler());
