java - NTLM 身份验证 Android Studio

Question

我花了很多时间试图弄清楚如何在 Android Studio 上执行 NTLM 身份验证，但没有成功。我意识到 NTLM 不是 Android 原生的。最近一直在用JCIFS库

jcifs.Config.registerSmbURLHandler();
URL url = new URL("https://domain%5cuser:pass@host");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

但是我得到了错误

"Unable to find default handler for protocol: https"

相同的代码适用于标准 Java。在这一点上，我已经用尽了我找到的所有建议，但我不知道该怎么做。

我试图解决同样的问题，并遇到了以下链接(类粘贴在下面以防链接失效): https://lists.samba.org/archive/jcifs/2013-July/010105.html

然后我使用以下命令强制使用处理程序:

    jcifs.Config.registerSmbURLHandler();

    System.setProperty("http.auth.ntlm.domain", domain);
    System.setProperty("jcifs.smb.client.domain", domain);
    System.setProperty("jcifs.smb.client.username", username);
    System.setProperty("jcifs.smb.client.password", password);
    System.setProperty("java.protocol.handler.pkgs", "domain.com.package");

但是，我遇到了问题，因为返回的响应是空的，因此需要在那里进行更多调查。
