HttpClinent用法，url请求

今天项目上碰到一个请求接口获取到报文中某个参数，将这个参数放到另一个请求上拼接，完成请求，获取其报文数据入库的需求，刚开始一脸懵啊！这个该怎么做啊（技术小白）...就网上各种百度呀，脑壳疼呀。终于....
开始：首先定位maven坐标，pom文件中添加：

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
    </dependency>

这时候就可以使用httpclinent了。

          get请求:
  public static  void httpClientGetTest() throws URISyntaxException {
        //创建HttpClient对象
        CloseableHttpClient httpClient = HttpClients.createDefault();
        //无参url
        //HttpGet httpGet = new HttpGet("http://www.baidu.com");
        //有参url后面的addParameter,可以无限的追加不用使用&分割自动添加;

    URIBuilder uriBuilder = new URIBuilder("http://www.baidu.com").addParameter("wd", "新闻");
    HttpGet httpGet = new HttpGet(uriBuilder.toString());
    try {
            //发起请求,获取结果
            CloseableHttpResponse response= httpClient.execute(httpGet);
            //返回值200为响应成功
            if (response.getStatusLine().getStatusCode() == 200) {
                //获取响应实体
                HttpEntity entity = response.getEntity();
                //转码
                String utf8 = EntityUtils.toString(entity, "utf8");
                System.out.println(utf8);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
}

    post 用法
  public static void httpClientPostTest() throws UnsupportedEncodingException {

    //创建httpClient对象
    CloseableHttpClient aDefault = HttpClients.createDefault();

    //设置发送表单内容数据
    ArrayList<NameValuePair> nameValuePairs = new ArrayList<>();
    //使用NameValuePair的实现类添加键值对的参数 键值对格式
    nameValuePairs.add(new BasicNameValuePair("wd","音乐"));

    //创建表单entity对象就是封装好的参数的bean,前面是参数后面是编码
    UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(nameValuePairs, "utf8");
    //创建Post请求对象
    HttpPost httpPost = new HttpPost("http://www.baidu.com");

}

代码也附加一下吧，欢迎各位指出问题

    }  
    return null;

    Date now = new Date();  
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");//可以方便地修改日期格式  
String hah = dateFormat.format(now);  

    String result\_juid = httpClint("http://12.12.12.120/dsst.jhtml?account=11&password=22");

嗯！就是这样没错了，具体问题再具体分析吧，目前我还没有碰到其他的，告辞......
