c# - 使用现有数据库的 ServiceStack 身份验证

Question

我一直在研究 ServiceStack，并试图了解如何在具有现有数据库的服务上使用 BasicAuthentication。我想生成一个公钥(用户名)和 secret key (密码)并将其放入现有用户记录中。然后，用户会将其与他们的请求一起传递给 ServiceStack 端点。

我需要在 ServiceStack 堆栈中实现什么才能使其正常工作？

我查看了 IUserAuthRepository 和 CredentialsAuthProvider 基类，看起来我应该在现有数据库表的基础上实现 IUserAuthRepository。

我也在尝试弄清楚我应该实现什么才能使身份验证正常工作。我不会使用该服务来添加或更新用户对服务的访问权限，而是使用单独的 Web 应用程序。

非常感谢任何帮助和过去的经验。

针对现有数据库进行身份验证的示例(在本例中是通过 Umbraco/ASP.NET 成员(member)系统)。 1) 创建您的 AuthProvider(请原谅冗长的代码，请注意您不必也覆盖 TryAuthenticate，这样做是为了检查用户是否是特定 Umbraco 应用程序别名的成员):

using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Web.Security;

using ServiceStack.Configuration;
using ServiceStack.Logging;
using ServiceStack.ServiceInterface;
using ServiceStack.ServiceInterface.Auth;
using ServiceStack.WebHost.Endpoints;

using umbraco.BusinessLogic;
using umbraco.providers;

public class UmbracoAuthProvider : CredentialsAuthProvider
{

    public UmbracoAuthProvider(IResourceManager appSettings)
    {
        this.Provider = "umbraco";
    }

    private UmbracoAuthConfig AuthConfig
    {
        get
        {
            return EndpointHost.AppHost.TryResolve<UmbracoAuthConfig>();
        }
    }

    public override void OnAuthenticated(IServiceBase authService, IAuthSession session, IOAuthTokens tokens, Dictionary<string, string> authInfo)
    {
        ILog log = LogManager.GetLogger(this.GetType());
        var membershipProvider = (UsersMembershipProvider)Membership.Providers["UsersMembershipProvider"];

        if (membershipProvider == null)
        {
            log.Error("UmbracoAuthProvider.OnAuthenticated - NullReferenceException - UsersMembershipProvider");
            session.IsAuthenticated = false;
            return;
        }

        MembershipUser user = membershipProvider.GetUser(session.UserAuthName, false);

        if (user == null)
        {
            log.ErrorFormat(
                "UmbracoAuthProvider.OnAuthenticated - GetMembershipUser failed - {0}", session.UserAuthName);
            session.IsAuthenticated = false;
            return;
        }

        if (user.ProviderUserKey == null)
        {
            log.ErrorFormat(
                "UmbracoAuthProvider.OnAuthenticated - ProviderUserKey failed - {0}", session.UserAuthName);
            session.IsAuthenticated = false;
            return;
        }

        User umbracoUser = User.GetUser((int)user.ProviderUserKey);

        if (umbracoUser == null || umbracoUser.Disabled)
        {
            log.WarnFormat(
                "UmbracoAuthProvider.OnAuthenticated - GetUmbracoUser failed - {0}", session.UserAuthName);
            session.IsAuthenticated = false;
            return;
        }

        session.UserAuthId = umbracoUser.Id.ToString(CultureInfo.InvariantCulture);
        session.Email = umbracoUser.Email;
        session.DisplayName = umbracoUser.Name;
        session.IsAuthenticated = true;
        session.Roles = new List<string>();
        if (umbracoUser.UserType.Name == "Administrators")
        {
            session.Roles.Add(RoleNames.Admin);
        }

        authService.SaveSession(session);
        base.OnAuthenticated(authService, session, tokens, authInfo);
    }

    public override bool TryAuthenticate(IServiceBase authService, string userName, string password)
    {
        ILog log = LogManager.GetLogger(this.GetType());
        var membershipProvider = (UsersMembershipProvider)Membership.Providers["UsersMembershipProvider"];

        if (membershipProvider == null)
        {
            log.Error("UmbracoAuthProvider.TryAuthenticate - NullReferenceException - UsersMembershipProvider");
            return false;
        }

        if (!membershipProvider.ValidateUser(userName, password))
        {
            log.WarnFormat("UmbracoAuthProvider.TryAuthenticate - ValidateUser failed - {0}", userName);
            return false;
        }

        MembershipUser user = membershipProvider.GetUser(userName, false);

        if (user == null)
        {
            log.ErrorFormat("UmbracoAuthProvider.TryAuthenticate - GetMembershipUser failed - {0}", userName);
            return false;
        }

        if (user.ProviderUserKey == null)
        {
            log.ErrorFormat("UmbracoAuthProvider.TryAuthenticate - ProviderUserKey failed - {0}", userName);
            return false;
        }

        User umbracoUser = User.GetUser((int)user.ProviderUserKey);

        if (umbracoUser == null || umbracoUser.Disabled)
        {
            log.WarnFormat("UmbracoAuthProvider.TryAuthenticate - GetUmbracoUser failed - {0}", userName);
            return false;
        }

        if (umbracoUser.UserType.Name == "Administrators"
            || umbracoUser.GetApplications()
                          .Any(app => this.AuthConfig.AllowedApplicationAliases.Any(s => s == app.alias)))
        {
            return true;
        }

        log.WarnFormat("UmbracoAuthProvider.TryAuthenticate - AllowedApplicationAliases failed - {0}", userName);

        return false;
    }
}

public class UmbracoAuthConfig
{

    public UmbracoAuthConfig(IResourceManager appSettings)
    {
        this.AllowedApplicationAliases = appSettings.GetList("UmbracoAuthConfig.AllowedApplicationAliases").ToList();
    }

    public List<string> AllowedApplicationAliases { get; private set; }

}

2) 通过常规的 AppHost Configure 方法注册提供者:

    public override void Configure(Container container)
    {
        // .... some config code omitted....

        var appSettings = new AppSettings();
        AppConfig = new AppConfig(appSettings);
        container.Register(AppConfig);

        container.Register<ICacheClient>(new MemoryCacheClient());

        container.Register<ISessionFactory>(c => new SessionFactory(c.Resolve<ICacheClient>()));

        this.Plugins.Add(
            new AuthFeature(
                // using a custom AuthUserSession here as other checks performed here, e.g. validating Google Apps domain if oAuth enabled/plugged in.
                () => new CustomAuthSession(), 
                new IAuthProvider[] { new UmbracoAuthProvider(appSettings) 
                                    }) {
                                          HtmlRedirect = "/api/login" 
                                       });

}

3) 现在可以对现有的 Umbraco 数据库进行身份验证 @ yourapidomain/auth/umbraco，使用 Umbraco 管理用户/访问 API。无需实现额外的用户 key / secret 或 BasicAuthentication，除非您真的想要....
