使用 httpclient 4.x 验证单个请求

我有一个由多个线程共享的 HttpClient 实例。我想用它来发出单个经过身份验证的请求。因为只应验证单个请求，所以我不想按照文档。这是我已经解决的问题，但不起作用。据我所知，CredentialsProvider 看起来根本没有被使用。有什么建议吗？

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);

I have an HttpClient instance that's shared by a number of threads. I would like to use it to make a single authenticated request. Because only the single request should be authenticated, I don't want to modify the HttpClient instance as described in the documentation. Here's what I've worked out instead, which isn't working. From what I can tell, it doesn't look like the CredentialsProvider is being used at all. Any tips?

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。我使用此处指南实现了 NTLM 身份验证。我修改了问题中列出的代码，使其看起来像这样并且有效：

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);

It turns out the server I was connecting to was only offering NTLM authentication. I implemented NTLM authentication using the guide here. I modified the code listed in my question to look like so and it works:

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);
