Usage

From source file:org.archive.modules.credential.HttpAuthenticationCredential.java

@Override
public boolean populate(CrawlURI curi, HttpClient http, HttpMethod method,
        Map<String, String> httpAuthChallenges) {
    boolean result = false;

    AuthChallengeProcessor authChallengeProcessor = new AuthChallengeProcessor(http.getParams());
    try {//from   ww w . j  a v  a 2s  .c  o  m
        AuthScheme authScheme = authChallengeProcessor.processChallenge(method.getHostAuthState(),
                httpAuthChallenges);
        method.getHostAuthState().setAuthScheme(authScheme);
    } catch (MalformedChallengeException e) {
        return result;
    } catch (AuthenticationException e) {
        return result;
    }

    // Always add the credential to HttpState. Doing this because no way of
    // removing the credential once added AND there is a bug in the
    // credentials management system in that it always sets URI root to
    // null: it means the key used to find a credential is NOT realm + root
    // URI but just the realm. Unless I set it everytime, there is
    // possibility that as this thread progresses, it might come across a
    // realm already loaded but the login and password are from another
    // server. We'll get a failed authentication that'd be difficult to
    // explain.
    //
    // Have to make a UsernamePasswordCredentials. The httpclient auth code
    // does an instanceof down in its guts.
    UsernamePasswordCredentials upc = null;
    try {
        upc = new UsernamePasswordCredentials(getLogin(), getPassword());
        http.getState().setCredentials(
                new AuthScope(curi.getUURI().getHost(), curi.getUURI().getPort(), getRealm()), upc);
        logger.fine("Credentials for realm " + getRealm() + " for CrawlURI " + curi.toString()
                + " added to request: " + result);

        http.getParams().setParameter(AuthPolicy.AUTH_SCHEME_PRIORITY,
                Arrays.asList(AuthPolicy.DIGEST, AuthPolicy.BASIC));

        result = true;
    } catch (URIException e) {
        logger.severe("Failed to parse host from " + curi + ": " + e.getMessage());
    }

    return result;
}
