 3.解决

　　测试回调成功，但是发现返回结果带了引号，可能是导致回调不成功原因。下面代码为错误示范。

    [HttpGet, Route("callback/interAspect")]
        public IActionResult ReveiceMsg(string msg_signature,string timestamp,string nonce,string echostr)
        {
            //验证
            WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(AppSetting.Configuration["Wx:CallBackToken"]
                , AppSetting.Configuration["Wx:EncodingAESKey"]
                , AppSetting.Configuration["Wx:corpid"]);
            
            int ret = 0;
            string sEchoStr = "";
            ret = wxcpt.VerifyURL(msg_signature, timestamp, nonce, echostr, ref sEchoStr);
            if (ret != 0)
            {
                return Json(null);
            }

            return Json(sEchoStr);
        }

返回值调整为ContentResult 或者string 后测试成功。

 [HttpGet, Route("callback/interAspect")]
        public ContentResult ReveiceMsg(string msg_signature,string timestamp,string nonce,string echostr)
        {
            //验证
            WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(AppSetting.Configuration["Wx:CallBackToken"]
                , AppSetting.Configuration["Wx:EncodingAESKey"]
                , AppSetting.Configuration["Wx:corpid"]);
            
            int ret = 0;
            string sEchoStr = "";
            ret = wxcpt.VerifyURL(msg_signature, timestamp, nonce, echostr, ref sEchoStr);
            if (ret != 0)
            {
                return Content(null);
            }

            return Content(sEchoStr);
        }

最后成功保存
