HttpClient请求地址并携带参数

废话不多，直接上代码！

     /**
      *
      * @param httpUrl
      * @param reqInfo
      * @return
      */
     public static StringBuffer sendPost(String httpUrl, RequestInfoDTO reqInfo) {
         try {
             logger.info("请求地址 --->" + httpUrl);
             PostMethod postMethod = new PostMethod(httpUrl);
             HttpClient httpClient = new HttpClient();
             String requestJson = com.bocins.springcloud.util.JsonUtils.obj2Json(reqInfo);
             logger.info("请求参数转json --->" + requestJson);
             postMethod.setRequestEntity(new StringRequestEntity(requestJson, "text/xml", "GBK"));
             httpClient.executeMethod(postMethod);
             BufferedReader reader = null;
             reader = new BufferedReader(new InputStreamReader(postMethod.getResponseBodyAsStream(),"UTF-8"));
             String lines;
             StringBuffer sb = new StringBuffer("");
             while((lines = reader.readLine()) != null){
                 lines = new String(lines.getBytes());
                 sb.append(lines);
             }
             logger.info("服务调用返回结果 --->" + sb);
             return sb;
         }catch(Exception e){
             logger.info("****************服务调用出错****************",e);
         }
         return null;
     }
