Class AuthHandler

java.lang.Object
  wt.httpgw.AuthHandler

All Implemented Interfaces:

HTTPClient.AuthorizationHandler

public class AuthHandler

extends Object

implements HTTPClient.AuthorizationHandler

A simple authorization handler that throws up a message box requesting both a username and password. This is default authorization handler. Currently only handles the authentication types "Basic" and "SOCKS5" (used for the SocksClient and not part of HTTP per se). This code is heavily based on 'MyAuthHandler' -- a part of the HTTPClient package.

Method Summary

static String	ByteToHex(byte[] hash) Turns array of bytes into string representing each byte as unsigned hex number.
private static String	calc_digest(HTTPClient.RoRequest req, String A1_hash, String nonce) Calculates the digest of the request body.
HTTPClient.AuthorizationInfo	fixupAuthInfo(HTTPClient.AuthorizationInfo info, HTTPClient.RoRequest req, HTTPClient.AuthorizationInfo challenge, HTTPClient.RoResponse resp) For Digest authentication we need to set the uri, response and opaque parameters.

void	handleAuthTrailers(HTTPClient.Response resp, HTTPClient.RoRequest req, HTTPClient.AuthorizationInfo prev, HTTPClient.AuthorizationInfo prxy) We handle the "Authentication-info" and "Proxy-Authentication-info" trailers here.

                                           throws HTTPClient.AuthSchemeNotImplException

For Digest authentication we need to set the uri, response and opaque parameters. For "Basic" and "SOCKS5" nothing is done.

Specified by:

fixupAuthInfo in interface HTTPClient.AuthorizationHandler

Throws:

HTTPClient.AuthSchemeNotImplException

getAuthorization

public HTTPClient.AuthorizationInfo getAuthorization(HTTPClient.AuthorizationInfo challenge,
                                                     HTTPClient.RoRequest req,
                                                     HTTPClient.RoResponse resp)
                                              throws HTTPClient.AuthSchemeNotImplException

returns the requested authorization, or null if none was given.

Specified by:

getAuthorization in interface HTTPClient.AuthorizationHandler

Parameters:

challenge - the parsed challenge from the server.

resp - the full response received

Returns:

a structure containing the necessary authorization info, or null

Throws:

HTTPClient.AuthSchemeNotImplException - if the authentication scheme in the challenge cannot be handled.
