HttpClient client = new HttpClient();

- 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();
}
}
