"java.lang.UnsupportedOperationException:尚不支持." [英] "java.lang.UnsupportedOperationException: Not supported yet."

问题描述

我正在尝试做的事情:

我正在尝试使用Java连接到[使用https]的Web Portal.我已经编写了使用Authenticator类提供用户凭据的代码.运行该程序时，出现异常:

I am trying to connect to Web Portal [that uses https]using Java. I have written code for supplying user credentials using Authenticator class.When I run the program I get an Exception:

"java.lang.UnsupportedOperationException:尚不支持"

"java.lang.UnsupportedOperationException: Not supported yet"

我已经发布了代码:

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());
        }
    }
}

第二次尝试中引发了异常"java.lang.UnsupportedOperationException:目前尚不支持".我的方法正确吗?如果没有，还有其他选择吗?

the exception "java.lang.UnsupportedOperationException: Not supported yet"is raised in the 2nd Try.Is my approach correct ? if not is there any alternative to do so ?

在Web浏览器中打开页面时，会显示登录页面；一旦提供凭据，就会显示Web门户

When I open the page in web browser I get the login page;Once I supply my credentials the web portal is displayed

任何人都可以建议如何访问Webportal并提供我的凭据并检查身份验证是否成功吗?任何示例代码片段都将非常有帮助预先感谢..

Can any one please suggest how to hit the webportal and supply my credentials and check the authentication is success or not ? Any sample code snippets will be really helpful Thanks in advance..

推荐答案

您看过这段代码片段了吗?

Have you seen this code fragment ?

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

恰恰是每次您尝试进行身份验证时都会引发上述异常的人.

It's precisely the one that will throw the aforementionned exception each time you try to authenticate.

因此，在我看来，解决身份验证问题的方法非常简单:实施此方法.

So, to my mind, the solution to your authentication problem is quite simple : implement this method.
