  对于Basic-Auth，它看起来像这样：

  DefaultHttpClient httpclient = new DefaultHttpClient();
  httpclient.getCredentialsProvider().setCredentials(
      new AuthScope("PROXY HOST", 8080),
      new UsernamePasswordCredentials("username", "password"));
  
  HttpHost targetHost = new HttpHost("TARGET HOST", 443, "https");
  HttpHost proxy = new HttpHost("PROXY HOST", 8080);
  
  httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
  

  开箱即用不支持AFAIK NTLM . 但是您可以使用 NTCredentials 来管理它，并且可能会重载 DefaultProxyAuthenticationHandler .

  对于任何寻找4.3的答案的人来说...它相当新，他们的例子没有使用新的HttpClientBuilder ......所以我在这个版本中实现了这个：

  NTCredentials ntCreds = new NTCredentials(ntUsername, ntPassword,localMachineName, domainName );
  
  CredentialsProvider credsProvider = new BasicCredentialsProvider();
  credsProvider.setCredentials( new AuthScope(proxyHost,proxyPort), ntCreds );
  HttpClientBuilder clientBuilder = HttpClientBuilder.create();
  
  clientBuilder.useSystemProperties();
  clientBuilder.setProxy(new HttpHost(pxInfo.getProxyURL(), pxInfo.getProxyPort()));
  clientBuilder.setDefaultCredentialsProvider(credsProvider);
  clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());
  
  CloseableHttpClient client = clientBuilder.build();

  可以使用4.3 httpClient上的普通旧用户名和密码代替NTLM，如下所示：

  HttpHost proxy = new HttpHost("x.x.com",8080);
  Credentials credentials = new UsernamePasswordCredentials("username","password");
  AuthScope authScope = new AuthScope("x.x.com", 8080);
  CredentialsProvider credsProvider = new BasicCredentialsProvider();
  credsProvider.setCredentials(authScope, credentials);
  HttpClient client = HttpClientBuilder.create().setProxy(proxy).setDefaultCredentialsProvider(credsProvider).build();
  HttpResponse response=client.execute(new HttpGet("http://stackoverflow.com/questions/6962047/apache-httpclient-4-1-proxy-authentication"));

  如何使用Apache的httpclient设置代理身份验证

  （代理网络上的预授权）

  这个答案使用Apache的HttpClient v4.1及更高版本 .

  接受的答案对我不起作用，但我找到了其他的东西！

  以下是来自apache的一些经过测试验证的代码，演示了如何通过代理对HTTP请求进行身份验证 .

  完整文档位于：https://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html .

  Apache也有一个很好的例子：https://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientProxyAuthentication.java

  • 用您的代理用户名替换 my_username

  • 用您的代理密码替换 my_password

  • 将 proxy.mycompany.com 替换为您的代理主机

  • 将 8080 替换为您的代理端口

  • 将 google.com 替换为要将HTTP请求发送到的站点的主机 .

  • 将 /some-path 替换为您要将HTTP请求发送到的路径 . 这使用您之前指定的主机站点（google.com） .

  The following example will authenticate username:password@proxy.mycompany.com:8080 and send a GET request to http://www.google.com/some-path and will print the response HTTP code.

  CredentialsProvider credsProvider = new BasicCredentialsProvider();
      credsProvider.setCredentials(
              new AuthScope("proxy.mycompany", 8080),
              new UsernamePasswordCredentials("my_username", "my_password"));
      CloseableHttpClient httpclient = HttpClients.custom()
              .setDefaultCredentialsProvider(credsProvider).build();
      try {
          //Replace "google.com" with the target host you want to send the request to
          HttpHost target = new HttpHost("google.com", 80, "http");
          HttpHost proxy = new HttpHost("proxy.mycompany", 8080);
  
          RequestConfig config = RequestConfig.custom()
              .setProxy(proxy)
              .build();
          CloseableHttpResponse response = null;
  
          //Replace "/some-path" with the path you want to send a get request to.
          HttpPost httppost = new HttpPost("/some-path");
          httppost.setConfig(config);
          response = httpclient.execute(target, httppost);
  
          try {
              System.out.println("Return status code is "+response.getStatusLine().getStatusCode());          
          } finally {
              response.close();
          }
      } finally {
          httpclient.close();
      }

  对NTLM来说，一件简单的事情对我有用：

  httpclient.getCredentialsProvider().setCredentials(
                      new AuthScope(proxy_host, proxy_port), 
                      new NTCredentials(this.proxy_user, this.proxy_pass, this.proxy_host, this.proxy_domain));
  HttpHost proxy = new HttpHost(this.proxy_host, this.proxy_port, "http");
  httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

  对于HttpClient 4.5和每个请求身份验证：

  HttpContext httpContext = new BasicHttpContext();
  AuthState authState = new AuthState();
  
  authState.update(new BasicScheme(), new UsernamePasswordCredentials("userName", "password"));
  httpContext.setAttribute(HttpClientContext.PROXY_AUTH_STATE, authState);
  CloseableHttpResponse httpResponse = httpClient.execute(httpRequest, httpContext);
