使用 CloseableHttpClient

/** 

  * post json格式 

  * @param url 调用接口 

  * @param para  json格式数据 

  */ 

   public  static String sendPost(String url, String data) {  

          String response = null; 

          try { 

              CloseableHttpClient httpclient = null; 

              CloseableHttpResponse httpresponse = null; 

              try { 

                  httpclient = HttpClients.createDefault(); 

                  HttpPost httppost = new HttpPost(url); 

                  StringEntity stringentity = new StringEntity(data, 

                          ContentType.create("text/json", "UTF-8")); 

                  httppost.setEntity(stringentity); 

                  httpresponse = httpclient.execute(httppost);//关键一步 

                  response = EntityUtils 

                          .toString(httpresponse.getEntity(),"utf-8");//加上utf-8参数防止中文乱码 

                 System.out.println(response); 

              } finally { 

                  if (httpclient != null) { 

                      httpclient.close(); 

                  } 

                  if (httpresponse != null) { 

                      httpresponse.close(); 

                  } 

              } 

          } catch (Exception e) { 

              e.printStackTrace(); 

          } 

          return response; 

      }

使用HttpURLConnection

 /**
  * 向指定URL发送GET方法的请求

  * @param url
  *            发送请求的URL
  * @param param
  *            请求参数，请求参数应该是 name1=value1&name2=value2 的形式。
  * @return URL 所代表远程资源的响应结果
  */
 public static String sendGet(String url, String param) {
 String result = "";
 BufferedReader in = null;
 try {
 String urlNameString = url + "?" + param;
 URL realUrl = new URL(urlNameString);
 // 打开和URL之间的连接

 // 设置通用的请求属性

 // 定义 BufferedReader输入流来读取URL的响应

 connection.getInputStream(),"utf-8"));
 String line;
 while ((line = in.readLine()) != null) {

 }
 } catch (Exception e) {
