微信开放平台之获取用户信息的授权方式扩展

在SENPARC底层,提供了微信用户授权验证的方式:

namespace Senparc.Weixin.MP.Sample.Filters
{
    /// <summary>
    /// OAuth自动验证,可以加在Action或整个Controller上
    /// </summary>
    public class CustomOAuthAttribute : SenparcOAuthAttribute
    {
        public CustomOAuthAttribute(string appId, string oauthCallbackUrl)
            : base(appId, oauthCallbackUrl)
        {
            base._appId = base._appId ?? System.Configuration.ConfigurationManager.AppSettings["TenPayV3_AppId"];
        }

        public override bool IsLogined(HttpContextBase httpContext)
        {
            return httpContext != null && httpContext.Session["OpenId"] != null;

            //也可以使用其他方法如Session验证用户登录
            //return httpContext != null && httpContext.User.Identity.IsAuthenticated;
        }
    }
}

在我近期的项目中进行了一些扩展:

            //return httpContext != null && httpContext.User.Identity.IsAuthenticated;
        }
    }
}

目前要基于开放平台进行开发,也需要获取用户的信息,开放平台获取用户返回的信息跟公众号的不一样,分别如下:

 公众号的用户:  Senparc.Weixin.MP.AdvancedAPIs.User.UserInfoJson.cs,我这里增加了  [Serializable]

                NLogHelper.Info("OAuthOpenCallback,WechatUserInfo=" + wechatUserInfo.FastToJson() + ",returnUrl=" + returnUrl);
                // 改为存储UserInfoJson对象
                Session[GlobalSetting.WechatOpenIdSessionKey] = wechatUserInfo;
            }
            catch (ErrorJsonResultException ex)
            {
                return Content(ex.Message);
            }

            return Redirect(returnUrl);
        }

 

大家对这个在开放平台获取用户授权方式有什么建议呢?
