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;
  }
}
