java.lang.Object
  com.ebay.carad.os.vitalsigns.util.NanoHTTPD

public class NanoHTTPD
extends java.lang.Object

A simple, tiny, nicely embeddable HTTP 1.0 server in Java

NanoHTTPD version 1.1, Copyright © 2001,2005-2007 Jarno Elonen (elonen@iki.fi, http://iki.fi/elonen/)

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
• Supports both dynamic content and file serving
• 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 does the 301 redirection trick for directories without '/'
• File server supports simple skipping for files (continue download)
• File server uses current directory as a web root
• 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 from current directory and shows requests
• Subclass serve() and embed to your own program
• Call serveFile() from serve() with your own base directory

Method Detail

serve

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

Override this to customize the server.

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

Returns:

HTTP response, see class Response for details

main

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

Starts as a standalone file server and waits for Enter.

encodeUri

private java.lang.String encodeUri(java.lang.String uri)

URL-encodes everything between "/"-characters. Encodes spaces as '%20' instead of '+'.

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.
