[Building Sakai] EB client example code?

[Stephen Marquard]

For reference (and Google), 

kernel-util/src/main/java/org/sakaiproject/util/BasicAuth.java

/**
 * This is implemented in a filter, since most httpclients (i.e. non
browser
 * clients) don't know what to do with a redirect.
 *
 * There are 2 mechanisms for selecting basic authentication. 1. The
client is
 * not a browser as reported by the BasicAuthFilter.isBrowser method.
2. The
 * user requested basic auth in the URL and the
 * BasicAuthFilter.requestedBasicAuth confirms this.
 *
 * in sakai.properties if allow.basic.auth.login = true, then this
feature is
 * enabled in BasicAuthFilter, the determination of non browser clients
is
 * driven by matching user agent headers against a sequence of regex
patterns.
 * These are defined in BasicAuthFilter with the form if the pattern
matches a
 * browser 1pattern or if it does not match 0pattern
 *
 * Additional patterns may be added to sakai.properties as a multiple
string
 * property against login.browser.user.agent
 *
 * The list is matched in order, the first match found being
definitive. If no
 * match is found, then the client is assumed to be a browser.
 *
 * e.g. if itunes was not listed as a client, either:
 *
 * Add
 *
 *    login.browser.user.agent.count=1
 *    login.browser.user.agent.1=0itunes.*
 *
 * to sakai.properties, or
 *
 * Add __auth=basic to the end of the url, e.g.
 *
 *   
http://localhost:8080/access/wiki/123-1231-32123-132123/-.20.rss?someparam=someval&__auth=basic

 *
 * This string is available in
BasicAuthFilter.BASIC_AUTH_LOGIN_REQUEST
 *

EB generally delegates the auth to Sakai.

>From
/direct/src/java/org/sakaiproject/entitybroker/servlet/SakaiDirectServlet.java

    public void handleUserLogin(HttpServletRequest req,
HttpServletResponse res, String path) {
        // attempt basic auth first
        try {
            if (basicAuth.doAuth(req, res)) {
                return;
            }
        } catch (IOException ioe) {
            throw new RuntimeException("IO Exception intercepted
during logon ", ioe);
        }

        // get the Sakai session (using the cover)
        Session session = SessionManager.getCurrentSession();
....

So you will need to have basic auth enabled to use the basic auth
portion. In that same way, you have to have the session keys enabled
to use that part. Otherwise you have login directly in the same way
you would for the access servlet (using normal user/pass challenge).
