钉钉新建套件回调Url问题

使用的是官方Java ISV demo    回调地址为url为:工程地址/isvreceive

调试过程能进去,但是Url参数(如下)都是null,请问这是什么问题?
** url中的签名 **/
            String msgSignature = request.getParameter("signature");
            /** url中的时间戳 **/
            String timeStamp = request.getParameter("timestamp");
            /** url中的随机字符串 **/
            String nonce = request.getParameter("nonce");

Re钉钉新建套件回调Url问题
已经fix了。原来会有两次调用，一次带参数一次不带。不带参数那次是因为安全问题故意做的保护性尝试。现在已经去掉不带参数的访问了。

回 2楼itas109的帖子
我的找到原因了
因为某些原因导致第一次调用失败之后，
再次创建的时候没有修改Env.java的ENCODING_AES_KEY从而失败的

如果参数是null，可以重试一次试试。
