JOpenID Version 1.05 Highlights
1. Configurable Extension Namespace AliasEven during JOpenID's intial release, support for OpenID Attribute Exchange is already available. The extension namespace alias used is hard-coded with a value of ext1. It was Ok to do this back then because Yahoo still doesn't support OpenID Attribute Exchange during those times. But now that Yahoo already does (see this article), we did some test and found out Yahoo has it's own extension namespace alias requirement. As an RP connecting to Yahoo for OpenID authentication you must use this specific alias or else you won't be able to query any info aside from the Identity. That's why in this version of JOpenID we decided to add support for configurable extension namespace aliases to solve this issue. How to use this new featureUsing the MainServlet from Developer's Guide as our basis, we modify it's doGet method to now look this way: @Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String op = request.getParameter("op");
if (op==null) {
// check nonce:
checkNonce(request.getParameter("openid.response_nonce"));
// get authentication:
HttpSession session = request.getSession();
byte[] mac_key = (byte[]) session.getAttribute(ATTR_MAC);
String alias = (String) session.getAttribute(ATTR_ALIAS);
Authentication authentication = manager.getAuthentication(request, mac_key, alias);
String identity = authentication.getIdentity();
String email = authentication.getEmail();
// TODO: create user if not exist in database:
showAuthentication(response.getWriter(), identity, email);
}
else if ("Google".equals(op) || "Yahoo".equals(op)) {
// redirect to Google/Yahoo sign on page:
Endpoint endpoint = manager.lookupEndpoint(op);
Association association = manager.lookupAssociation(endpoint);
HttpSession session = request.getSession();
session.setAttribute(ATTR_MAC, association.getRawMacKey());
session.setAttribute(ATTR_ALIAS, endpoint.getAlias());
String url = manager.getAuthenticationUrl(endpoint, association);
response.sendRedirect(url);
}
else {
throw new ServletException("Bad parameter op=" + op);
}
}Notice that we are now storing two attributes in session. One is the ATTR_MAC and the other one is ATTR_ALIAS. The getAuthentication method also has an added new parameter, the alias we stored in the session from the previous call. 2. Additional AttributesOn this version of JOpenID we also added new properties to the Authentication class. Aside from email you can now also get the fullname, firstname, lastname, language, and gender as long as they are supported by the chosen OP at runtime. How to use this new featureUsing again the MainServlet from Developer's Guide as our basis, we modify it's showAuthentication method to now look this way: void showAuthentication(PrintWriter pw, Authentication user) {
pw.print("<html><body>");
pw.print(" <h2>Hi "+user.getFullname()+"!</h2><p>Congratulations, you have successfully logged-in!</p>");
pw.print("<p><b>Indentity:</b> "+user.getIdentity()+"<br>");
pw.print("<b>Email:</b> "+user.getEmail()+"<br>");
pw.print("<b>Gender:</b> "+user.getGender()+"<br>");
pw.print("<b>Firstname:</b> "+user.getFirstname()+"<br>");
pw.print("<b>Lastname:</b> "+user.getLastname()+"<br>");
pw.print("<b>Language:</b> "+user.getLanguage()+"</p>");
pw.print("</body></html>");
pw.flush();
}Do not forget to also modify the MainServlet's doGet method where a call to showAuthentication is used: .
.
Authentication authentication = manager.getAuthentication(request, mac_key, alias);
// TODO: create user if not exist in database:
showAuthentication(response.getWriter(), authentication);
.
