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;
         }
