谢了，看到文档里写的了，https://open-doc.dingtalk.com/doc2/detail.htm?spm=a219a.7629140.0.0.Dp4dJv&treeId=171&articleId=104934&docType=1#s0

//代码贴给你，你就明白拉。
//前台JS获取timeStamp :
var d = new Date();
var timeStamp = Date.parse(d);  //当前日期减去1970年1月1号的值
//后台获取签名，即signature,其中nocestr是在前台自己设置的一个值
public string getSignInfo(string nocestr,string jsapi_ticket,string timestamp,string url)
        {
            var str = string.Format("jsapi_ticket={0}&noncestr={1}&timestamp={2}&url={3}",jsapi_ticket,nocestr,timestamp,url);
            return SHA1Encrypt(str).ToLower();
        }
        internal static string SHA1Encrypt(string str)
        {
            byte[] StrRes = Encoding.Default.GetBytes(str);
            HashAlgorithm iSHA = new SHA1CryptoServiceProvider();
            StrRes = iSHA.ComputeHash(StrRes);
            StringBuilder EnText = new StringBuilder();
            foreach (byte iByte in StrRes)
            {
                EnText.AppendFormat("{0:x2}", iByte);
            }
            return EnText.ToString();
        }
