微信开发之c#下缓存jssdk的access_token

因为access_token的寿命只有7200秒,每日获取access_token存在上限,所以在获取access_token后,需要将其缓存起来.

首先建立一个模型

 public class AccessToken

    {
        public string access_token { get; set; }

        public DateTime expires_in { get; set; }

    }

然后存储获取的access_token(获取方法),和当前的时间

    public static void Save()
        {
            var accessToken = new AccessToken();
            accessToken.access_token = a_token;
            accessToken.expires_in = DateTime.Now;
            //存储
            System.Web.HttpContext.Current.Application["accessToken"] = accessToken;
            //获取
            //var accessToken = System.Web.HttpContext.Current.Application["accessToken"] as AccessToken;
        }
