Asp.net Boilerplate之AbpSession扩展

2018-06-22 07:43:38来源：未知阅读 ()

当前Abp版本1.4.2,项目类型为MVC5.

以属性的形式扩展AbpSession,并在"记住我"后,下次自动登录也能获取到扩展属性的值,版权归"角落的白板报"所有!

step1.添加IAbpSessionExtensions接口:

    /// <summary>
    /// IAbpSession Extensions 登录时"记住我"保存Cookie,也就是说关闭后再打开不重新登录的话,取得到值.
    /// </summary>
    public interface IAbpSessionExtensions : IAbpSession
    {
        string UserName { get; }
        string EmailAddress { get; }
        string Name { get; }
        string FullName { get; }
        string Surname { get; }
    }

step2.添加实现类AbpSessionExtensions:

/// <summary>
    /// IAbpSession Extensions
    /// </summary>
    public class AbpSessionExtensions : ClaimsAbpSession, IAbpSessionExtensions
    {

/// 如果是之前的版本,此处的构造函数会有所不同,只要把这个构造函数删除,再根据Vs的提示生成默认实现就可以.

　　　　　　public AbpSessionExtensions(IPrincipalAccessor principalAccessor,
　　　　　　　　IMultiTenancyConfig multiTenancy, ITenantResolver tenantResolver,
　　　　　　　　IAmbientScopeProvider<SessionOverride> sessionOverrideScopeProvider)
　　　　　　　　　　: base(principalAccessor, multiTenancy, tenantResolver, sessionOverrideScopeProvider)
　　　　　　{
　　　　　　}

　　　　 public string EmailAddress => GetKeyValue(ClaimTypes.Email);
        public string Surname => GetKeyValue(ClaimTypes.Surname);
        public string Name => GetKeyValue(ClaimTypes.Name);
        public string UserName => GetKeyValue(EnglishConsts.ClaimTypes.UserName);
        public string FullName => GetKeyValue(EnglishConsts.ClaimTypes.FullName);

        private string GetKeyValue(string key)
        {
            var claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;

            if (claimsPrincipal == null)
            {
                return null;
            }

            var claim = claimsPrincipal.Claims.FirstOrDefault(c => c.Type == key);
            if (string.IsNullOrEmpty(claim?.Value))
            {
                return null;
            }

            return claim.Value;

        }
    }

step3.在Mvc控制器基类(项目名称ControllerBase)里添加AbpSession属性:

        //IAbpSession Extensions
        public new IAbpSessionExtensions AbpSession { get; set; }

step4.在Account控制器的SignInAsync方法里成功登录后(AuthenticationManager.SignIn(new AuthenticationProperties { IsPersistent = rememberMe }, identity),添加需要扩展的属性:

            //IAbpSession Extensions
            identity.AddClaim(new Claim(ClaimTypes.Email, user.EmailAddress));
            identity.AddClaim(new Claim(ClaimTypes.Name, user.Name));
            identity.AddClaim(new Claim(ClaimTypes.Surname, user.Surname));
　　　　　　　//这个常量自己去定义
            identity.AddClaim(new Claim(EnglishConsts.ClaimTypes.UserName, user.UserName));
            identity.AddClaim(new Claim(EnglishConsts.ClaimTypes.FullName, user.FullName));

step5.这里我定义了两个自定义常量,加在了项目名称Consts常量定义文件里:

 public class EnglishConsts
    {
        public const string LocalizationSourceName = "English";

        public class ClaimTypes
        {
            public const string UserName = "UserName";
            public const string FullName = "FullName";
        }
    }
