HttpClient client = new HttpClient();
PostMethod pm = new PostMethod(prop.getProperty("createInstanceURL"));

Properties prop = new Properties()

prop.load(InstanceHandler.class.getClassLoader().getResourceAsStream("/rest.properties"));

NameValuePair [] data = {new NameValuePair("pgmCode", pgmCode),new NameValuePair("parentId", parentId)};
    pm.setRequestBody(data);
    int statusCode = client.executeMethod(pm);;
    if(statusCode == HttpStatus.SC_MOVED_PERMANENTLY || statusCode ==HttpStatus.SC_MOVED_TEMPORARILY) {
            //4.读response
        Header locationHeader = pm.getResponseHeader("location");
          //6.处理得到的内容
        String location = "";
        if(locationHeader != null) {
          location = locationHeader.getValue();
          logger.debug("The page was redirected to: "+location);
        } else {
        logger.debug("Location field value was null");
                 }
             }
             return;
