JSP开发中Apache-HTTPClient 用户验证的实例详解
前言：
在微服务框架之外的系统中，我们经常会遇到使用httpClient进行接口调用的问题，除了进行白名单的设置，很多时候我们需要在接口调用的时候需要身份认证。翻了一下官方文档，解决方法很多，但是都不太符合实际业务场景，这里提供一种简单粗暴的解决方法。
解决方法：利用请求头，将验证信息保存起来。
实现代码：

public class HttpClientUtils {
  protected static final Logger LOG = LoggerFactory.getLogger(HttpClientUtils.class);
  private static final String AUTHENKEY = "Authorization";
  private static final String BASICKEY = "Basic ";
  public static String getConnect(String url,String username,String password) {
  CloseableHttpResponse response = null;
  CloseableHttpClient client = HttpClients.createDefault();
  HttpGet httpGet = new HttpGet(url);
  Base64 token = new Base64();
  String authenticationEncoding = token.encodeAsString(new String(username + ":" + password).getBytes());
  httpGet.setHeader(AUTHENKEY, BASICKEY + authenticationEncoding);
  String responseContent = "";
  try {
    response = client.execute(httpGet);
    HttpEntity entity = response.getEntity();
    responseContent = EntityUtils.toString(entity, "UTF-8");
  } catch (IOException e) {
    LOG.error(e.toString());
  } finally {
    if (response != null) {
    try {
      response.close();
    } catch (IOException e) {
      LOG.error(e.toString());
    }
    }
    if (client != null) {
    try {
      client.close();
    } catch (IOException e) {
      LOG.error(e.toString());
    }
    }
  }
  return responseContent;
  }

}
