https://api.weixin.qq.com/wxa/generate_urllink?access_token=ACCESS_TOKEN

String accessToken = CommonUtils.getAccessToken();
JSONObject jsonObject = new JSONObject();
jsonObject.put("path", "/pages/index/index");
if(Objects.isNull(accessToken)){
    throw new BusinessException("1001","获取小程序token信息失败！");
}
String url = "https://api.weixin.qq.com/wxa/generate_urllink?access_token=" + accessToken;
String s = CommonUtils.sendPost(url, jsonObject.toJSONString());

这种返回的结果一直报错：

{"errcode":0,"errmsg":"ok","url_link":"******"}

这个接口调不通，请问大佬们知道怎么解决嘛
