public class NanoHTTPD
extends java.lang.Object

A simple, tiny, nicely embeddable HTTP 1.0 (partially 1.1) server in Java

NanoHTTPD version 1.25, Copyright © 2001,2005-2012 Jarno Elonen (elonen@iki.fi, http://iki.fi/elonen/) and Copyright © 2010 Konstantinos Togias (info@ktogias.gr, http://ktogias.gr) Improvements in Thread Handling (pooling) by Jeffrey I. Schiller (jis@mit.edu)

Features + limitations:

• Only one Java file
• Java 1.1 compatible
• Released as open source, Modified BSD licence
• No fixed config files, logging, authorization etc. (Implement yourself if you need them.)
• Supports parameter parsing of GET and POST methods (+ rudimentary PUT support in 1.25)
• Supports both dynamic content and file serving
• Supports file upload (since version 1.2, 2010)
• Supports partial content (streaming)
• Supports ETags
• Never caches anything
• Doesn't limit bandwidth, request time or simultaneous connections
• Default code serves files and shows all HTTP parameters and headers
• File server supports directory listing, index.html and index.htm
• File server supports partial content (streaming)
• File server supports ETags
• File server does the 301 redirection trick for directories without '/'
• File server supports simple skipping for files (continue download)
• File server serves also very long files without memory overhead
• Contains a built-in list of most common mime types
• All header names are converted lowercase so they don't vary between browsers/clients

Ways to use:

• Run as a standalone app, serves files and shows requests
• Subclass serve() and embed to your own program
• Call serveFile() from serve() with your own base directory

Constructor Detail

NanoHTTPD

public NanoHTTPD(int port,
         java.io.File wwwroot)
          throws java.io.IOException

Starts a HTTP server to given port.

Throws an IOException if the socket is already in use

Throws:

java.io.IOException

Method Detail

serve

public NanoHTTPD.Response serve(java.lang.String uri,
                       java.lang.String method,
                       java.util.Properties header,
                       java.util.Properties parms,
                       java.util.Properties files,
                       java.net.Socket mySocket)

Override this to customize the server.

(By default, this delegates to serveFile() and allows directory listing.)

Parameters:

uri - Percent-decoded URI without parameters, for example "/index.cgi"

method - "GET", "POST" etc.

parms - Parsed, percent decoded parameters from URI and, in case of POST, data.

header - Header entries, percent decoded

Returns:

HTTP response, see class Response for details

stop

public void stop()

Stops the server.

main

public static void main(java.lang.String[] args)

Starts as a standalone file server and waits for Enter.

serveFile

public NanoHTTPD.Response serveFile(java.lang.String uri,
                           java.util.Properties header,
                           java.io.File homeDir,
                           boolean allowDirectoryListing)

Serves file from homeDir and its' subdirectories (only). Uses only URI, ignores all headers and HTTP parameters.
