java - 使用 httpclient 4.x 验证单个请求

Question

我有一个HttpClient由多个线程共享的实例。我想用它来发出一个经过身份验证的请求。因为应该只对单个请求进行身份验证，所以我不想按照文档HttpClient中的描述修改实例。这是我已经解决的问题，但它不起作用。据我所知，它看起来根本没有被使用。有小费吗？CredentialsProvider

HttpContext context = null;
if(feedSpec.isAuthenticated()) {
  context = new BasicHttpContext();
  CredentialsProvider credsProvider = new BasicCredentialsProvider();
  credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(feedSpec.getHttpUsername(), feedSpec.getHttpPassword()));
  context.setAttribute(ClientContext.CREDS_PROVIDER, credsProvider);
  context.setAttribute(ClientPNames.HANDLE_AUTHENTICATION, true);
}
HttpGet httpGet = new HttpGet(feedSpec.getUri());
HttpResponse httpResponse = httpClient.execute(httpGet, context);

事实证明，我连接的服务器只提供 NTLM 身份验证。我使用此处的指南实现了 NTLM 身份验证。我修改了我的问题中列出的代码，看起来像这样，它可以工作：

HttpContext context = null;
if(feedSpec.isAuthenticated()) {
    context = new BasicHttpContext();
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(AuthScope.ANY, new NTCredentials(feedSpec.getHttpUsername(), feedSpec.getHttpPassword(), "", ""));
    context.setAttribute(ClientContext.CREDS_PROVIDER, credsProvider);
}
HttpGet httpGet = new HttpGet(feedSpec.getUri());
HttpResponse httpResponse = httpClient.execute(httpGet, context);
