.net core 在abp中扩展abpsession

1、定义扩展类

/// <summary>
    /// IAbpSession扩展类
    /// </summary>
    public static class SessionExtensions
    {
        /// <summary>
        /// 当前用户角色信息
        /// </summary>
        /// <param name="session"></param>
        /// <returns></returns>
        public static string GetRolesCode(this IAbpSession session)
        {
            try
            {
                var claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
                var claim = claimsPrincipal?.Claims.FirstOrDefault(c => c.Type == "rolesCode");
                if (claim == null || string.IsNullOrEmpty(claim.Value))
                {
                    return null;
                }
                return claim.Value.ToString();
            }
            catch
            {
                return null;
            }
        }
    }

2、为扩展的abpssion填充数据，可以在全局入口或者过滤器中定义。这里我使用action过滤器来做。

public class MyActionFilterAttribute : ActionFilterAttribute
    {
        private LoginMode _loginModel;
        /// <summary>
        /// 过滤器
        /// </summary>
        /// <param name="loginModel">登录类型</param>
        public MyActionFilterAttribute(LoginMode loginModel)
        {
            _loginModel = loginModel;
        }

       

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            string authType = ConfigManagerConf.GetValue("AppSetting:AuthType");
            if (authType == "debug")
            {
                string userId = "0";
                string userName = "system";
                string allCompany = "true";
                string companyId = "1";
                string rolecode = "pps_publish";
                CreateIdentity(userId, userName, allCompany, companyId, rolecode, filterContext.HttpContext);
            }
            base.OnActionExecuting(filterContext);
        }




        /// <summary>
        /// 添加用户数据到ClaimsIdentity，为扩展自定义IAbpSession准备数据
        /// </summary>
        /// <param name="userId"></param>
        /// <param name="userName"></param>
        /// <param name="allCompany"></param>
        /// <param name="companyId"></param>
        private void CreateIdentity(string userId, string userName, string allCompany, string companyId, string rolecodes, HttpContext HttpContext)
        {
            var claimsIdentity = new ClaimsIdentity();
            claimsIdentity.AddClaim(new Claim(ClaimTypes.NameIdentifier, userId, ClaimValueTypes.String));
            claimsIdentity.AddClaim(new Claim(ClaimTypes.Name, userName, ClaimValueTypes.String));
            claimsIdentity.AddClaim(new Claim("IsAllCompany", allCompany, ClaimValueTypes.String));
            claimsIdentity.AddClaim(new Claim("CompanyId", companyId, ClaimValueTypes.String));
            claimsIdentity.AddClaim(new Claim("rolesCode", rolecodes, ClaimValueTypes.String));
            var claimsPrincipal = new ClaimsPrincipal(claimsIdentity);
            Thread.CurrentPrincipal = claimsPrincipal;
            HttpContext.SignInAsync(claimsPrincipal);
            Thread.Sleep(10);
        }

    }

这样，就可以直接在应用层通过AbpSession或者在表示层构造函数注入IAbpSession来获取扩展字段的值了。
