apache httpcomponents 摘要认证失败，旧的httpclient工作答案

【问题标题】：apache httpcomponents digest authentication failes, old httpclient worksapache httpcomponents 摘要认证失败，旧的httpclient工作

【问题描述】：

我有一个通过 web.xml 中的摘要身份验证保护的 solr 服务器，我需要从 java 调用 solr。我今天阅读了大量线程并做了很多示例，但没有运气。

我有这个代码与 commons-httpclient 3.1 一起工作，我得到了 200 OK。

    URL url = new URL(solrUrl);

    HttpClient httpClient = new HttpClient(new MultiThreadedHttpConnectionManager());
    httpClient.getState().setCredentials(new AuthScope(url.getHost(), url.getPort(), AuthScope.ANY_SCHEME),
            new UsernamePasswordCredentials(user, password));

    HttpMethod method = new GetMethod(solrUrl);
    int responseCode = httpClient.executeMethod(method);
    System.out.println(responseCode);

但是当我尝试使用 apache httpcomponent 4.2.2 时，我总是得到未经授权的 401。这和官方的例子几乎一模一样。

       DefaultHttpClient httpclient = null;
    try
    {
        URL url = new URL(solrUrl);
        HttpHost targetHost = new HttpHost(url.getHost(), url.getPort(), url.getProtocol());
        httpclient = new DefaultHttpClient();
        UsernamePasswordCredentials creds = new UsernamePasswordCredentials(user, password);
        httpclient.getCredentialsProvider().setCredentials(
                new AuthScope(targetHost.getHostName(),targetHost.getPort()),
                creds);


        HttpGet httpget = new HttpGet(solrUrl);
        HttpResponse response = httpclient.execute(targetHost,httpget);
        HttpEntity entity = response.getEntity();
        System.out.println(response.getStatusLine());
        EntityUtils.consume(entity);

        httpget.releaseConnection();


    } catch (ClientProtocolException e)
    {
        e.printStackTrace();
    } catch (IOException e)
    {
        e.printStackTrace();
    }  finally
    {
        httpclient.getConnectionManager().shutdown();
    }

我也尝试使用 HttpUrlConnection 并始终获得相同的 401。

Authenticator authenticator = new Authenticator()
    {
        protected PasswordAuthentication getPasswordAuthentication()
        {
            PasswordAuthentication pa = new PasswordAuthentication(user, password.toCharArray());
            System.out.println("calling solr with user:pass " + pa.getUserName() + ":******");
            return pa;
        }
    };

    Authenticator.setDefault(authenticator);
    try
    {
        URL url = new URL(solrUrl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("type", "submit");
        conn.setDoOutput(true);

        conn.connect();
    System.out.println( conn.getResponseCode());


        conn.disconnect();
    } catch (MalformedURLException mue)
    {
        mue.printStackTrace();
    } catch (IOException ioe)
    {
        ioe.printStackTrace();
    } catch (Exception e)
    {
        e.printStackTrace();
    }

由于类路径问题，我想使用 apache httpcomponents 4，我正在放弃..

有什么帮助吗？

【解决方案1】：

回答我自己：显然我遇到了 jdk + tomcat 错误的组合：

java bug

tomcat bug

它发生在 jdk 1.6.0_45-b06 和 tomcat 7.0.34，升级 tomcat 到 7.0.41 修复它。

谢谢。过去两天我一直在为此感到压力，我所需要的只是获得最新的 tomcat。
