使用Apache HTTPClient进行身份验证错误

Question

我正在尝试通过经过身份验证的代理发出请求，如下所示

<div class="sliders">
  <label for="name1">John</label><input id="name1" type="range" min="0" max="1.0" step="0.01" />
  <label for="name2">Jacob</label><input id="name2" type="range" min="0" max="1.0" step="0.01" />
  <label for="name3">Jingleheimer</label><input id="name3" type="range" min="0" max="1.0" step="0.01" />
  <label for="name4">Schmidt</label><input id="name4" type="range" min="0" max="1.0" step="0.01" />
</div>

我的问题是它给了我以下错误，我不太明白。我怀疑我可能没有使用正确的类来进行身份验证。

HttpHost proxy = new HttpHost("http-proxy", 80);
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(
            user, password));

    try (CloseableHttpClient client = HttpClientBuilder.create().setDefaultCredentialsProvider(credsProvider)
            .build()) {
        HttpPost post = new HttpPost(url);

        RequestConfig config = RequestConfig.custom().setProxy(proxy).build();
        post.setConfig(config);

        post.setEntity(new UrlEncodedFormEntity(urlParameters));

        HttpResponse response = client.execute(post);

        return response;
    }

似乎MS代理服务器配置有问题。您可以disable NTLM in HTTP client尝试基本身份验证，或者如果必须使用NTLM / Kerberos，请尝试HTTP wire logs以进一步解决问题。
