proxy如何解决需要用户名密码

首先获取代理, 并且判断是否代理打开

/**
    * 获取代理
    * 
    * @return
    */
   private Map<String,Object> getProxy()
   {
      Map<String,Object> map = new HashMap<String,Object>();

      HttpHost httphost = null;
      InputStream in = this.getClass().getClassLoader().getResourceAsStream("app-context.properties");
      if (in != null)
      {
         Properties prop = new Properties();
         try
         {
            prop.load(in);
            String proxy = "";
            String proxyList = prop.getProperty("hcproxy.proxyList");  //在app-context.properties中设置的代理列表, 格式: proxyUrl:port/username:pwd
            if(null != proxyList && StringUtils.isNotBlank(proxyList)){
               String[] proArr = proxyList.split(",");
               Random random = new Random();
               int i = random.nextInt(proArr.length); //ip列表溢出问题
               proxy = proArr[i];
               if (!"".equals(proxy) && null != proxy)
               {
                  logger.info("用于发送请求的代理ip:" + proxy);
                  String[] array = proxy.split("/");
                  String host = array[0].split(":")[0];
                  String prot = array[0].split(":")[1];
                  httphost = new HttpHost(host, Integer.parseInt(prot));
                  if(array.length > 1){
                     String userAndPwd = array[1];  //用户名和密码
                     map.put("userAndPwd",userAndPwd);
                  }

                  map.put("httphost",httphost);
               }
            }

         }
         catch (IOException e)
         {
            logger.error("动态读取配置文件错误:" + e.getMessage(), e);
         }
      }
      return map;
   }

/**
 * 判断代理开关是否打开
 * 
 * @return
 */
private boolean isProxyOn()
{
   boolean open = false;
   InputStream in = this.getClass().getClassLoader().getResourceAsStream("app-context.properties");
   if (in != null)
   {
      Properties prop = new Properties();
      try
      {
         prop.load(in);
         String isOn = prop.getProperty("isProxyOn");
         if ("1".equals(isOn))
         {
            open = true;
         }
      }
      catch (IOException e)
      {
         logger.error("动态读取配置文件错误:" + e.getMessage(), e);
      }
   }
   return open;
}

一开始的时候并不需要用户名密码, 这样就可以获取返回数据

public CloseableHttpResponse post1(String url, List<NameValuePair> formparams) throws Exception
{
   HttpPost httpPost = new HttpPost(url);
   httpPost.setHeader("x-requested-with", "XMLHttpRequest");
   UrlEncodedFormEntity uefEntity = new UrlEncodedFormEntity(formparams, "UTF-8");
   httpPost.setEntity(uefEntity);
   // 组装代理
   if (isProxyOn())
   {
      Map<String,Object> mapProxy = getProxy();
      HttpHost proxy = (HttpHost) mapProxy.get("httphost");
      if (null != proxy)
      {
         RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(5000).setSocketTimeout(30000)
               .setProxy(proxy).build();
         httpPost.setConfig(requestConfig);
      }
   }
   CloseableHttpResponse HttpResponse = closeableHttpClient.execute(httpPost);
   return HttpResponse;
}

但后来要使用了(目标地址需要, 逼不得已), 所以原来的方法不能用了

改成这样

public CloseableHttpResponse post(String url, Map<String, String> map) throws Exception
{
   HttpPost httpPost = new HttpPost(url);
   if (map != null)
   {
      // 创建参数队列
      List<NameValuePair> formparams = new ArrayList<NameValuePair>();
      // 封装参数
      for (Map.Entry<String, String> m : map.entrySet())
      {
         formparams.add(new BasicNameValuePair(m.getKey(), m.getValue()));
      }
      UrlEncodedFormEntity uefEntity = new UrlEncodedFormEntity(formparams, "UTF-8");
      uefEntity.setContentType("application/x-www-form-urlencoded; charset=UTF-8");
      httpPost.setEntity(uefEntity);
   }
   // 组装代理
   if (isProxyOn())
   {
      Map<String,Object> mapProxy = getProxy();
      HttpHost proxy = (HttpHost) mapProxy.get("httphost");
      if (null != proxy)
      {
         CredentialsProvider credsProvider = new BasicCredentialsProvider();

         //要设置用户名密码的代理
         if(null != mapProxy.get("userAndPwd")){
            String username = ((String) mapProxy.get("userAndPwd")).split(":")[0];
            String password = ((String) mapProxy.get("userAndPwd")).split(":")[1];
            //创建认证，并设置认证范围
            logger.info("代理用户名: " + username + " 密码: " + password);
            credsProvider.setCredentials(new AuthScope(proxy.getHostName(),proxy.getPort()),   //可以访问的范围
                        new UsernamePasswordCredentials(username,password));      //用户名和密码
            //重新创建client
            this.closeableHttpClient = HttpClientUtil.getIgnoreSslCertificateHttpClient(credsProvider);
         }

         RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(5000).setSocketTimeout(30000)
               .setProxy(proxy).build();
         httpPost.setConfig(requestConfig);
      }
   }
   CloseableHttpResponse HttpResponse = closeableHttpClient.execute(httpPost);
   return HttpResponse;
}

其中, 因为目标有证书验证, 所以需要忽略证书

//忽略证书
    public static CloseableHttpClient getIgnoreSslCertificateHttpClient(CredentialsProvider credsProvider) throws HttpException {

        SSLContext sslContext = null;
        try {
            sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {

                @Override
                public boolean isTrusted(final X509Certificate[] arg0, final String arg1)
                        throws CertificateException {

                    return true;
                }
            }).build();
        } catch (Exception e) {
            throw new HttpException("can not create http client.", e);
        }
        SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext,
                new NoopHostnameVerifier());
        Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder
                .<ConnectionSocketFactory> create()
                .register("http", PlainConnectionSocketFactory.getSocketFactory())
                .register("https", sslSocketFactory).build();
        PoolingHttpClientConnectionManager connMgr = new PoolingHttpClientConnectionManager(
                socketFactoryRegistry);
        //keep alive 连接策略
        ConnectionKeepAliveStrategy connectionKeepAliveStrategy = new ConnectionKeepAliveStrategy() {
            @Override
            public long getKeepAliveDuration(HttpResponse httpResponse, HttpContext httpContext) {
                return 30 * 1000; // tomcat默认keepAliveTimeout为20s
            }
        };
        connMgr.setMaxTotal(200);
        connMgr.setDefaultMaxPerRoute(200);
//        RequestConfig requestConfig = RequestConfig.custom()
//                .setConnectTimeout(10 * 1000)
//                .setSocketTimeout(10 * 1000)
//                .setConnectionRequestTimeout(10 * 1000)
//                .build();
        RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(5000).setSocketTimeout(30000).build();
        return HttpClientBuilder.create()
                .setSslcontext(sslContext)
                .setConnectionManager(connMgr)
                .setDefaultRequestConfig(requestConfig)
                .setKeepAliveStrategy(connectionKeepAliveStrategy)
                .setDefaultCredentialsProvider(credsProvider)
                .build();
    }

还有些没写, 过后补上

另参考给代理ip设置用户名密码:
