处理请求方法

@Override
    	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
    	{
    		resp.setHeader("content-type","text/html;charset=UTF-8");
    		resp.setHeader("Access-Control-Allow-Origin", "*");
    		String respMsg = "ok";
    
    		try
    		{
    			String  json=req.getParameter("json");
    			String  reqUrl=req.getParameter("reqUrl");
    			System.out.println(json+"  :"+reqUrl);
    			
    			Map<String,String> param = JSON.parseObject(json,Map.class);
    
    			respMsg = HttpFormUtil.formForward(reqUrl, param);
    			System.out.println("[请求信息:]"+param);
    		}
    		catch (Exception e)
    		{
    			respMsg="系统异常！";
    		}
    		resp.getOutputStream().write(respMsg.getBytes("utf8"));
    	}
