Question

我有一台带有“my_ip”的服务器，其中SSL是通过apache2启用的。它也受密码保护。我有用户名和密码。当我输入https://my_ip/com/dir1/dir2时，它会提示我输入凭据。现在我想通过java将dir2或dir2本身的内容下载到我的机器上。我该怎么做？

我尝试了以下方法，

Authenticator.setDefault(new Authenticator()
             {
      protected PasswordAuthentication getPasswordAuthentication() {
        String prompt = getRequestingPrompt();
        System.out.println(prompt);
        String host = getRequestingHost();
        System.out.println(host);
        InetAddress adresseIP = getRequestingSite();
        System.out.println(adresseIP);
        int port = getRequestingPort();
        System.out.println (port);
        String username = "username";
        String password = "password";
        return new PasswordAuthentication(username, password.toCharArray());
      }
    });
        URL url = new URL("https://my_ip/com/dir1/dir2/test.xml");
        // print URL Content
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
        String str;
        while ((str = in.readLine()) != null) {
          System.out.println(str);
        }
        in.close();
      }

但是我收到以下错误：

我在这里做错了什么？

试试这个。

String url = "https://selfsolve.apple.com/wcResults.do";
    URL obj = new URL(url);
    HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

如何通过https从受密码保护的URL下载目录？
