微信用户鉴权获取openid，code可以得到Openid为空

@At
    public String  getCode(@Param("code")String code) {
    	PropertiesProxy conf =new PropertiesProxy();
        logger.info(code);
        conf.setPaths("/custom");
        String appid = conf.get("weixin.appid");
        String appsecret = conf.get("weixin.appsecret");
        String fmt = "https://api.weixin.qq.com/sns/oauth2/access_token"
                + "?appid=%s"
                + "&secret=%s"
                + "&code=%s"
                + "&grant_type=authorization_code";
        String url = String.format(fmt,appid,appsecret,code);
        logger.info(url);
        String json = Http.get(url).getContent();
        logger.info("resp"+json);
        NutMap map = Json.fromJson(NutMap.class, json);
        logger.info("map"+map);
        String openid = map.getString("openid");
        logger.info("用户的标识"+openid);

        return openid;
    }

我的wk设置了回调url这里只需要获得code然后掉接口获取openid就可以了但是获得的openid为空
