Subject HttpClient 4.1.2 can not customize authentication by use the method that mentioned in "HTTP authentication and execution context" section 4.6.
Date Mon, 19 Sep 2011 13:11:52 GMT
When i write some code dealing with unfuddle api, i need use the Http Baisc
authentication, so i search the HttpClient Document, then i found this:

   -

   *ClientContext.TARGET_AUTH_STATE='http.auth.target-scope': *
AuthState instance
   representing the actual target authentication state. The value of this
   attribute set in the local context takes precedence over the default one.
   -

   *ClientContext.PROXY_AUTH_STATE='http.auth.proxy-scope': *
AuthState instance
   representing the actual proxy authentication state. The value of this
   attribute set in the local context takes precedence over the default one.

 Is the means  i can make a HttpContext then set a AuthState object
with ClientContext.TARGET_AUTH_STATE
key, then it can override the default one that init in
DefaultRequestDirector constructor(line 305 ~ 306 in
DefaultRequestDirector.java)?

*But when i run this method:*
    @Test
    public void unfuddle() throws IOException {
        HttpContext context = new BasicHttpContext();
        AuthState auth = new AuthState();
        auth.setAuthScheme(new BasicScheme());
        auth.setCredentials(new UsernamePasswordCredentials("wyatt",
"XXXXXXXXX"));
        auth.setAuthScope(AuthScope.ANY);

        //context.setAttribute(ClientContext.PROXY_AUTH_STATE, auth);
        context.setAttribute(ClientContext.TARGET_AUTH_STATE, auth);

System.out.println(context.getAttribute(ClientContext.TARGET_AUTH_STATE));
        try {
            String html = HttpClientManager.getInstance().fetchHTML(new
HttpGet("https://lmate.unfuddle.com/api/v1/projects.xml"), context);
        } catch(Exception e) {
            System.out.println(e.getMessage());

System.out.println(context.getAttribute(ClientContext.TARGET_AUTH_STATE));
        }
//        System.out.println(html);
    }

I get the Log:
*auth scope [<any realm>]; credentials set [true]  --- the one set by me.*

Is the AuthState object i set into HttpContext should override the
default AuthState
object?
