•   使用httpunit处理HTTP Basic Authentication验证登录,

需要将httpunit源代码里的com.meterware.httpunit.WebClient.java类里的下面这行注释掉:
//throw new AuthorizationRequiredException( response.getHeaderField( "WWW-Authenticate" ) );

import com.meterware.httpunit.*;

/** This is a simple example of using HttpUnit to read and understand web pages. **/
public class LoginRoute {

    public static void main( String[] params ) {
        try {
            // create the conversation object which will maintain state for us
            WebConversation wc = new WebConversation();

 

           
            HttpUnitOptions.setScriptingEnabled(false);//禁用javascript
            HttpUnitOptions.setAcceptCookies(true);
            String credit = "username" + ":" + "password";
            String encoding = new sun.misc.BASE64Encoder().encode (credit.getBytes());
     
           

            // Obtain the main page on the meterware web site
            WebRequest request = new GetMethodWebRequest( "http://itindex.net/" );
           
            request.setHeaderField("Authorization", "Basic " + encoding);
          
            
            WebResponse response = wc.getResponse( request );

            // find the link which contains the string "HttpUnit" and click it
            WebLink httpunitLink = response.getFirstMatchingLink( WebLink.MATCH_CONTAINED_TEXT, "HttpUnit" );

            // print out the number of links on the HttpUnit main page
            System.out.println( "The HttpUnit main page contains " + response.getLinks().length + " links" );
           
            System.out.println(response.getText());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
