C# 钉钉注册回调接口二开

[allenfu]

谁有范例吗?


Register.html -ajax 调用 Register.ashx 注册 http://221.***.**.130:8013/Ding.ashx 接口 ，来做钉钉审批实例的处理。

点注册 返回上图错误 ， 如何才能跟踪到Ding.ashx ,点注册 设断点 ，直接 Register.ashx 执行完就结束了
Register.ashx
--------
public void ProcessRequest (HttpContext context)
{


context.Response.ContentType = "text/plain";

string accToken = DingDll.SqlHelper.ReadToken(); //获取 Token
DefaultDingTalkClient client = new DefaultDingTalkClient(Urls.RegisterCallBack);
OapiCallBackRegisterCallBackRequest req = new OapiCallBackRegisterCallBackRequest();
req.Url = "http://221.**.**.130:8013/Ding.ashx";
req.AesKey = "45skhqweass5232345IUJKWEDL5251054DSFdsuhfW2"; //随机生成43位字串
req.Token = "123456"; //随机填写
List<string> arrMsg = new List<string>(); //填写要监控的信息
arrMsg.Add("bpms_task_change");
arrMsg.Add("bpms_instance_change");
req.CallBackTag = arrMsg;
OapiCallBackRegisterCallBackResponse rep = client.Execute(req, accToken);
string ss = rep.Body;
context.Response.Write( ss);
