"java.lang.UnsupportedOperationException:尚不支持."

Question

我想做什么:

我正在尝试使用Java连接到Web Portal [使用https].我编写了使用Authenticator类提供用户凭据的代码.当我运行程序时,我得到一个异常:"java.lang.UnsupportedOperationException:Not supported yet"

我发布了代码:

__CODE__ 根据Dreamweaver:

public class Main {

    public class MyAuthenticator extends Authenticator {

        protected PasswordAuthentication getpasswordAuthentication() {
            String username = "username";
            String password = "password";
            // Return the information
            return new PasswordAuthentication(username, password.toCharArray());
        }

        @Override
        public Result authenticate(HttpExchange he) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
    }

    public static void main(String[] args) {
        // TODO code application logic here


        TrustManager[] trustClients = new TrustManager[]{
            new X509TrustManager() {

                public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {

                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                    //throw new UnsupportedOperationException("Not supported yet.");
                }
            }
        };
        try {
            SSLContext sslcontext = SSLContext.getInstance("SSL");
            sslcontext.init(null, trustClients, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext.getSocketFactory());

        } catch (Exception e) {
            System.out.println("in 1st catch " + e);
        }


        try {
            URL url = new URL("https://someURL.server.com/fmk/jsp/ltpaLogin.jsp");
            URLConnection urlconnection = url.openConnection();
            System.out.println(urlconnection);
            System.out.print(urlconnection.getInputStream().toString());

        } catch (Exception e) {
            System.out.println("in 2ndcatch " + e.getMessage());
        }
    }
}

Answer 1

如果你不想实现这个方法:

    @Override
    public Result authenticate(HttpExchange he) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

放轻松,只删除这行方法:

throw new UnsupportedOperationException("Not supported yet.");

你见过这段代码吗？

    @Override
    public Result authenticate(HttpExchange he) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

每次尝试进行身份验证时,都会抛出上述异常.

因此,在我看来,您的身份验证问题的解决方案非常简单:实现此方法.
