自定义ServiceStack身份验证

我已经阅读了文档，并成功实现了一个自定义身份验证层，如下所示：

public class SmartLaneAuthentication : CredentialsAuthProvider
{
    private readonly SmartDBEntities _dbEntities;

    public SmartLaneAuthentication(SmartDBEntities dbEntities)
    {
        _dbEntities = dbEntities;
    }

    public override bool TryAuthenticate(IServiceBase authService, string userName, string password)
    {
        var user = _dbEntities.Users.FirstOrDefault(x => !((bool)x.ActiveDirectoryAccount) && x.UserName == userName);
        if (user == null) return false;

        // Do my encryption, code taken out for simplicity

        return password == user.Password;
    }

    public override void OnAuthenticated(IServiceBase authService, IAuthSession session, IOAuthTokens tokens, Dictionary<string, string> authInfo)
    {
        // user should never be null as it's already been authenticated
        var user = _dbEntities.Users.First(x => x.UserName == session.UserAuthName);
        var customerCount = _dbEntities.Customers.Count();
        session.UserName = user.UserName;
        session.DisplayName = user.DisplayName;
        session.CustomerCount = customerCount; // this isn't accessible?

        authService.SaveSession(session, SessionExpiry);
    }
}

然后，我在AppHost中注册它：

Plugins.Add(new AuthFeature(() => new SmartLaneUserSession(), 
    new IAuthProvider[]
    {
        new SmartLaneAuthentication(connection)
    })
{
    HtmlRedirect = null
});

Plugins.Add(new SessionFeature());

注意，我在SmartLaneUserSession下面使用“ like”，在其中添加了一个名为的自定义属性CustomerCount：

public class SmartLaneUserSession : AuthUserSession
{
    public int CustomerCount { get; set; }
}

当我尝试访问该属性以在类的OnAuthenticated方法中对其进行设置时，将SmartLaneAuthentication无法访问它。用户登录后如何访问和设置此属性？

在OnAuthenticated方法中，您需要将session（类型为IAuthSession）转换为会话对象类型，例如：

...
var customerCount = _dbEntities.Customers.Count();
var smartLaneUserSession = session as SmartLaneUserSession;
if(smartLaneUserSession != null)
{
    smartLaneUserSession.UserName = user.UserName;
    smartLaneUserSession.DisplayName = user.DisplayName;
    smartLaneUserSession.CustomerCount = customerCount; // Now accessible

    // Save the smartLaneUserSession object
    authService.SaveSession(smartLaneUserSession, SessionExpiry);
}

在您的服务中，您可以使用SessionAs<T>方法访问会话。因此，您可以使用：

public class MyService : Service
{
    public int Get(TestRequest request)
    {
        var session = SessionAs<SmartLaneUserSession>();
        return session.CustomerCount;
    }
}
