GET请求：java

@Override
public Object Get(List<SysNews> sysNewsList,Integer num, Integer offset) {
   CloseableHttpClient httpClient = HttpClients.createDefault();

       try {
           // 签名
           String utf8Tag = java.net.URLEncoder.encode(tag,"utf-8");
           String uri = String.format(GET_FEEDS_URI, utf8Tag, num, offset);
           String auth_string = ak + "\n" + auth_time + "\n" + rand_num + "\n" + uri;
       String encrypt_string = HUAJIAOSign.Base64.encode(HUAJIAOSign.hmacSha1(auth_string, sk));
       String authorization = ak + ":" + encrypt_string;//

           String url = String.format(GET_FEEDS_URL, utf8Tag, num, offset);
           HttpGet httpget = new HttpGet(url);

           //header中传递的参数
           httpget.setHeader("Authorization", authorization);//签名
           httpget.setHeader("Channelid", Channelid);//开放平台建立应用是系统分配的channelID
           httpget.setHeader("Auth-Time", auth_time);//请求时间戳
           httpget.setHeader("Rand-Num", rand_num);//随机数

   //执行请求
           HttpResponse httpResponse = httpClient.execute(httpget);
           if(httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
                   String result = EntityUtils.toString(httpResponse.getEntity());// 返回json格式：
                   response = JSONObject.fromObject(result);
               }
           } catch (Exception e) {
               log.error(e.toString());
           }

       return response;
}

POST请求：json

public static Object doPay(String url) {
   CloseableHttpClient httpClient = HttpClients.createDefault();

   JSONObject response = null;
       try {
           StringBuilder sb = new StringBuilder();
           // 签名
           String auth_string = ak + "\n" + auth_time + "\n" + rand_num + "\n" + GET_FEEDS_URI;
       String encrypt_string = HUAJIAOSign.Base64.encode(HUAJIAOSign.hmacSha1(auth_string, sk));
       String authorization = ak + ":" + encrypt_string;//

           log.info(" authorization======" + authorization);ide

           HttpPost post = new HttpPost(url);

           //header中传递的参数
           post.setHeader("Authorization", authorization);//签名
           post.setHeader("Channelid", "qianqianluhui");//开放平台建立应用是系统分配的channelID
           post.setHeader("Auth-Time", auth_time);//请求时间戳
           post.setHeader("Rand-Num", rand_num);//随机数

           //请求体
           //建立参数列表
List<NameValuePair> list = new ArrayList<NameValuePair>();
list.add(new BasicNameValuePair("platform", "server"));// 平台（固定值传server）
list.add(new BasicNameValuePair("tag", "video"));//标签
list.add(new BasicNameValuePair("num", "1"));// 每次返回数量(默认50条记录，取值范围1~100)
list.add(new BasicNameValuePair("offset", "0"));// 偏移量,上次请求返回offset值，首次传0或不传
//url格式编码
UrlEncodedFormEntity uefEntity = new UrlEncodedFormEntity(list,"UTF-8");
post.setEntity(uefEntity);

   //执行请求
           HttpResponse httpResponse = httpClient.execute(post);
           if(httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
               HttpEntity entity = httpResponse.getEntity();
               String result = EntityUtils.toString(httpResponse.getEntity());// 返回json格式：
               response = JSONObject.fromObject(result);
               }
           } catch (Exception e) {
               throw new RuntimeException(e);
           }

       return response;
   }post
