HTTP 响应 java

Question

I am building a HTTP Server in java

The problem is that the browser (Chrome) says that it can't connect to the server after waiting some time. until the timeout

it's like the browser doesn't get the response back.

I tried

• Using different ways to write the response
• Using a different port

The code i use for sending the response is:

        BufferedOutputStream writer = new BufferedOutputStream(outputStream);
        String CRLF = HTTPServer.CRLF;
        
        try (writer) {
            writer.write((this.getResponseLine() + CRLF).getBytes());
    
            for (Map.Entry<String, String> entry : headers.entrySet()) {
                writer.write((entry.getKey() + ": " + entry.getValue() + CRLF).getBytes());
            }
            writer.write(CRLF.getBytes());
            
            writer.write(this.getResponseBody());
            writer.flush();
        } catch (IOException e) {
            throw e;
        }

The headers are this:

return new HashMap<>() {{
           put("Content-Length", Integer.toString(content.length));
           put("Date", new Date().toString());
           put("Content-Type", contentMimeType.trim() + "; charset=" + HTTPServer.DEFAULT_CHARSET.displayName());
           put("Server", "Steampunk");
           put("Host", "localhost");
}};

to accept/handle the client i use a ServerSocket .

ss = new ServerSocket();
ss.bind(new InetSocketAddress("localhost", operatingPort));

Answer 1

If you mean to access this server from other machines try:

ss.bind(new InetSocketAddress("0.0.0.0", operatingPort));

That will listen on all interfaces and not restrict connections to the local machine as 'localhost' does.
