HttpUrlConnection没有'；在Android上找不到NTLM挑战

我正在尝试使用HttpUrlConnection类将我的Android应用程序连接到IIS服务器

我的服务器需要对用户进行身份验证，因此它正在向客户端发送以下质询：

WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM

我的问题是HttpUrlConnection似乎无法解析它。因此getPasswordAuthentication（）永远不会被调用，它返回一个IOException“找不到身份验证挑战”

这是我的密码：

Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {                  

            return new PasswordAuthentication("myUsername", "myPassword".toCharArray());
    }               
});

URL url = new URL(myUrl);               
HttpURLConnection conn = (HttpURLConnection) url.openConnection();          

conn.setRequestMethod("GET");
conn.setRequestProperty("Accept-Encoding", "gzip");
conn.setRequestProperty("Accept-Charset", "UTF-8");         
conn.setRequestProperty("Accept", "*/*");
conn.setRequestProperty("Connection", "close");
conn.setDoOutput(true);
conn.setDoInput(true);          

try 
{   
    conn.connect();             
    status_code = conn.getResponseCode();   
}catch (IOException e) {
    ...             
}

我真的开始认为HttpUrlConnection不支持NTLM挑战。我看到一些库似乎可以完成这项工作，但我不想使用外部库

有人能确认在没有外部LIB的情况下是否可以让HttpUrlConnection处理NTLM质询吗？

我只能通过设置下面的AuthScheme和库来使它与HttpClient一起工作：

然后在JCIFS引擎和工厂中实现。您可以在

HttpUrlConnection与NTLM中找到示例，使用库只需进行一些小的调整，例如删除您不需要的smb java代码并修复检索响应代码。

我们仍然可以使用HttpsURLConnection使其工作-定义身份验证程序并绕过证书验证（信任所有证书）

感谢是的，看起来用当前的HttpURLConnection类无法做到这一点。Regards@NLemay我有一个类似的情况，我现在必须重新考虑。一旦您成功地进行了身份验证，需要添加什么标头，或者需要做什么来“保持”整个会话的连接？我在这里写了一个详细的问题：@whyoz我刚才看了你的问题，但我没有使用你的库，所以我没有任何线索。但你试过eplozada的解决方案吗？HttpClient是一个广泛使用的库，您将从中获得更多帮助。但实际上我自己并没有尝试，我只是决定不支持Android上的NTLM。@NLemay是的，最终我可以进行身份验证并获得200状态，但我如何保持这种状态？我可以用eplozada的代码进行身份验证，但这并不能“永远”打开连接。关于这个问题有什么想法吗？在androidAn的httpsurlconnection中，有没有其他方法可以使用HttpURLConnection和jcifs对NTLM auth头进行身份验证。如果您找到任何解决方案，请联系我们
