本文介绍了一种使用Java实现的HTTP请求与响应处理方法，包括如何构造带有JSON体的POST请求，以及如何解析HTTP响应中的JSON数据。同时，还提供了不同版本的HttpClient设置超时时间的方法。

//http请求 body内容添加

public static void do_json_req(){
       HttpPost request = new HttpPost("http://localhost:8080/DSQ_Payment/uccb.do");
       JSONObject param_data = new JSONObject();
       param_data.put("orderId", "abcf1330");
       param_data.put("gameId", 123);
       param_data.put("accountId", "12221222211123");
       param_data.put("creator", "JY");
       param_data.put("payWay", 1);
       param_data.put("amount", "100.00");
       param_data.put("callbackInfo", "custominfo=xxxxx#user=xxxx");
       param_data.put("orderStatus", "S");
       param_data.put("failedDesc", "");
       param_data.put("cpOrderId", "1234567");

       JSONObject param = new JSONObject();

       param.put("ver", "2.0");
       param.put("data", param_data);
       param.put("sign", "6362e564f832d2e8bbcbd50e75409d47");
       // 绑定到请求Entry
       StringEntity se;
       try {
           se = new StringEntity(param.toString());
           request.setEntity(se);
           // 发送请求
           HttpResponse httpResponse = new DefaultHttpClient().execute(request);
           String retSrc = EntityUtils.toString(httpResponse.getEntity());
           // 生成 JSON 对象
//           JSONObject result = new JSONObject( retSrc);
//           String token = result.get("token");
           System.out.println(retSrc);
       } catch (Exception e) {
           e.printStackTrace();
       }

//http body内容接收

public String ucCB(HttpServletRequest req){

       UcpayCBVO uccbvo=null;
       String ret = "error....";
       try {
           BufferedReader bf = new BufferedReader(new InputStreamReader(req.getInputStream()));
           String line = "";
           String reqstr = "";
           while((line=bf.readLine()) != null){
               reqstr += line;
           }

           if(null != reqstr && !"".equals(reqstr)){
               Map<String, Object> f_map =PayUtil.jsonToMap(reqstr);
               Map<String, Object> map_json =(Map<String, Object>)f_map.get("data");
               map_json.put("ver", f_map.get("ver"));
               map_json.put("sign", f_map.get("sign"));
               reqstr=PayUtil.ObjectToJsonStr(map_json);
               uccbvo = (UcpayCBVO) PayUtil.jsonToObject(reqstr, UcpayCBVO.class);
               ret = ucService.callBackPayCenter(uccbvo);
           }
           log.debug("uccb: " + PayUtil.ObjectToJsonStr(uccbvo));
       } catch (Exception e) {
           log.error("uc cb error!", e);
       }
       log.debug("uc cb ret=" + ret + "; orderid=" + uccbvo.getOrderId());
       return ret;
   }

不是全部的代码，留下主要的两部分，给以后做参考~~

以下是HttpClient不同版本超时时间的设置

3.X是这样的

HttpClient client=new DefaultHttpClient();

client.setConnectionTimeout(30000);

client.setTimeout(30000);

4.X是这样的

HttpClient httpClient=new DefaultHttpClient();
httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,2000);//连接时间
httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,2000);//数据传输时间
4.3是这样的
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpGet httpGet=new HttpGet("http://www.baidu.com");//HTTP
 Get请求(POST雷同)
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(2000).setConnectTimeout(2000).build();//设置请求和传输超时时间
httpGet.setConfig(requestConfig);
httpClient.execute(httpGet);//执行请求
