带有代理NTLM Auth的Apache Client 4.3.4

Question

我必须发布一些数据，并且必须使用ntlm auth的代理。我的问题是，我从代理获得了407（需要代理身份验证）。我无法控制代理，所以我不能在这里调试！

客户端日志显示此代理状态：

1。）代理身份验证状态：UNCHALLENGED

2.。）代理身份验证状态：已挑战

3.。）代理身份验证状态：HANDSHAKE

也许有人可以检查我的代码，如果它应该有用，因为我希望代理设置是错误的。

NTCredentials ntCreds = new NTCredentials(ntUsername, ntPassword,localMachineName, domainName );

    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    HttpHost httpProxy = new HttpHost(InetAddress.getByName(proxyString), Integer.valueOf(proxyPort));
    credsProvider.setCredentials( new AuthScope(httpProxy), ntCreds );
    HttpClientBuilder clientBuilder = HttpClientBuilder.create();

    clientBuilder.setProxy(httpProxy);
    clientBuilder.setDefaultCredentialsProvider(credsProvider);
    clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());

    CloseableHttpClient client = clientBuilder.build();

    URI destination = new URI("http://requestb.in/1bpjk7g");
    HttpEntity entity = new StringEntity("test 123");
    HttpPost request = new HttpPost(destination);
    RequestConfig config = RequestConfig.custom().setProxy(httpProxy).build();
    request.setConfig(config );
    request.setEntity(entity);
    client.execute(request);
