“ java.lang.UnsupportedOperationException：尚不支持。”

Question

我正在尝试做的是：

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。运行程序时出现异常：

“ java.lang.UnsupportedOperationException：尚不支持”

我有张贴的代码：

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Try中引发了异常“
java.lang.UnsupportedOperationException：不支持”。我的方法正确吗？如果没有，还有其他选择吗？

当我在Web浏览器中打开页面时，我得到登录页面;一旦提供了凭据，就会显示Web门户

有人可以建议如何访问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对您有所帮助。

Answer 1

您看过这段代码片段了吗？

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

正是这种情况会在您每次尝试进行身份验证时引发上述异常。

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。
