JSP开发中Apache-HTTPClient 用户验证的实例详解

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;
  }


}
