//后台方法

//获取token

string token = string.Empty;

}

//获取ticket
using (WebClient wc = new WebClient())

获取签名，Url 为Request.Url

public static string getsign(string ticket,string timestamp,string url)
{
string arrString =
string.Format("jsapi_ticket={0}&noncestr=111111&timestamp={1}&url={2}", ticket,
timestamp,url);
string sign = FormsAuthentication.HashPasswordForStoringInConfigFile(arrString, "SHA1").ToLower();

return sign;
}
