Using Basic Authentication with OFBIZ

[Michael Imhof]

Following this link:
http://www.unix.org.ua/orelly/java-ent/servlet/ch08_01.htm
we can extend the OFBIZ SOAPEventHandler to support basic authentication.

Add the following code snipped to the start of SOAPEventHandler.invoke(..):

        Map serviceContext = new HashMap();
       
        String auth = request.getHeader("Authorization");

        try {
            // Do we have the authentication information?
            if (auth == null) {
                // Send response to get login information
                response.setHeader("WWW-Authenticate", "BASIC realm=\"users\"");
                response.sendError(response.SC_UNAUTHORIZED);
                return null;
            }
        } catch(IOException e) {
            sendError(response, e);
            throw new EventHandlerException("Error sending " + response.SC_UNAUTHORIZED + " response", e);
        }
       
        // Extract authentication information
        if (!auth.toUpperCase().startsWith("BASIC ")) {
            sendError(response, "Only basic authentication is supported!");
            throw new EventHandlerException("Only basic authentication is supported!");
        }

        // Get encoded user and password, comes after "BASIC "
        String userpassEncoded = auth.substring(6);

        try {
            // Decode it, using any base 64 decoder
            sun.misc.BASE64Decoder dec = new sun.misc.BASE64Decoder();
            String userpassDecoded = new String(dec.decodeBuffer(userpassEncoded));
           
            int sepIndex = userpassDecoded.indexOf(":");
            String user = userpassDecoded.substring(0, sepIndex);
            String pwd = userpassDecoded.substring(sepIndex + 1);
           
            serviceContext.put("login.password", pwd);
            serviceContext.put("login.username", user);
        } catch(IOException e) {
            sendError(response, e);
            throw new EventHandlerException("Error decoding authenticated information", e);
        }
