您如何通過 apache 的 commons httpclient 使用 NTLM 身份驗證以編程方式對 Web 服務器進行身份驗證？

Question

我正在使用此代碼，並獲得下面列出的堆棧跟蹤。 我只使用 https 和基本身份驗證，而不是 ntlm。

HttpClient client = null;
HttpMethod get = null;
try
{
  Protocol myhttps = new Protocol("https", ((ProtocolSocketFactory) new EasySSLProtocolSocketFactory()), 443);
  Protocol.registerProtocol("https", myhttps);
  client = new HttpClient();
  get = new GetMethod("https://tt.dummycorp.com/tmtrack/");
  Credentials creds = new NTCredentials("dummy", "dummy123", "host", "DUMMYDOMAIN");
  client.getState().setCredentials(AuthScope.ANY, creds);
  get.setDoAuthentication(true);
  int resultCode = client.executeMethod(get);
  System.out.println(get.getResponseBodyAsString());
}

Answer 1

HttpClient 不完全支持 NTLM。 請查看已知限制和問題。 關於 NTLM 的 HttpClient 文檔有點混亂，但最重要的是它們不支持 NTLMv2，這使得它在這方面幾乎不可用。

NTLM 由標准的 java HttpURLConnection ( link ) 支持，但 HttpClient 比 jdk 的 HttpURLConnection 有一些優勢。

Answer 2

看看這里發布的實用程序。

它解決了不同的問題，即缺少證書，而您安裝的證書無效，但它關於已安裝證書的詳細輸出可能會有所幫助。
