Question

我真的是Java编码的新手。请查看我的问题并帮助我解决。我试图从内部Web服务器中提取数据，该Web服务器最初已请求同一站点的“协商”身份验证，然后请求“基本”身份验证。

我试图通过创建if else循环来通过基本身份验证，但是如果条件始终处于'False状态并且仅执行else循环。并且也厌倦了通过标头中的基本身份验证，但是没有运气。

身份验证类以传递NTLM凭据

public class RunHttpSpnego {

static final String kuser = "user"; // your account name
static final String kpass = "pass"; // your password for the account

static class MyAuthenticator extends Authenticator {
    public PasswordAuthentication getPasswordAuthentication() {
        // I haven't checked getRequestingScheme() here, since for NTLM
        // and Negotiate, the usrname and password are all the same.
        System.err.println("Feeding username and password for " + getRequestingScheme());
        System.err.println("Feeding username and password for " + getRequestorType()+"URL: "+ getRequestingURL());
       if (getRequestingScheme().contains("Negotiate ")) {
            return (new PasswordAuthentication(kuser, kpass.toCharArray()));
        }
        else {
            String name = "test_dom\\user";
            String password = "pass";
            System.err.println("Block 1");
            return (new PasswordAuthentication(name, password.toCharArray()));

        }
      }
}

public static void main(String[] args) throws Exception {
        // Key to provide internal handshake 
    System.setProperty("javax.net.ssl.trustStore", "InternalAndExternalTrustStore.jks");
    System.setProperty("javax.net.ssl.trustStorePassword", "pass");

    Authenticator.setDefault(new MyAuthenticator());
    URL url = new URL("https://test_dom.com/users/directory.json");

    HttpURLConnection conn = (HttpURLConnection)url.openConnection();

          // Verified by passing basic authentication but no luck 
    //String auth = getAuthorization("test_dom\\user", "pass");
        //conn.setRequestProperty ("Authorization", "Basic " + auth);
    conn.setRequestProperty ("Content-Type", "application/json");

    InputStream ins = conn.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(ins));
    String str;
    while((str = reader.readLine()) != null)
        System.out.println(str);
}

private static String getAuthorization(String user, String password)
{
    try 
    {
        return getBase64((user + ":" + password).getBytes("UTF-8"));
    }
    catch (UnsupportedEncodingException e)
    {
        // Not thrown
    }

    return "";
}

private static String getBase64(byte[] buffer){

... }

}

这是上面的代码显示的错误：

Http URL连接首先请求协商，然后再请求同一URL的基本身份验证方案
