asp.net-mvc – 使用Windows身份验证和OWIN的ASP.NET MVC5 / AngularJS /

我可能是过于复杂的事情,但是我们有一个使用 Windows身份验证的AngularJS的内部ASP.NET MVC5 SPA.此应用程序具有SQL后端数据库,该数据库具有用户表,其中包含其帐户名称及其在应用程序中的相应角色.我们将拨打另一个启用Windows身份验证的Web API应用程序.

我已经尝试研究如何使用OWIN处理授权,但是找不到关于OWIN和Windows身份验证的任何具体示例.一切都会使用用户名和密码的表单身份验证.

我的应用程序如何使用OWIN和Windows Auth？以下是我的OAuthAuthorizationServerProvider类的示例.

public class SimpleAuthorizationServerProvider : OAuthAuthorizationServerProvider
{
    public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        context.Validated();
        return;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin",new[] { "*" });

        var container = UnityHelper.GetContainerInstance("***");
        var securityHelper = container.Resolve<ISecurityHelper>();

        User currentUser = securityHelper.GetCurrentUser(); // Validates user based on HttpContext.Current.User
        if (currentUser == null)
        {
            context.SetError("invalid_grant","The user could not be found.");
            return;
        }

        var identity = new ClaimsIdentity(context.Options.AuthenticationType);
        identity.AddClaim(new Claim("sub",currentUser.AccountName));
        identity.AddClaim(new Claim("role","user"));

        context.Validated(identity);
    }
}

更新：
糟糕,我忘了提供更多关于我们想要完成的信息.如果可能,我们想使用承载认证券,所以我们不必每次调用一个web api方法来查找用户和他们的角色.

更新2：
根据Andrew的要求,下面是我的_securityHelper类的TLDR版本,特别是GetCurrentUser()方法.你会注意到我试图打电话：

HttpContext.Current.GetOwinContext().Request.User.Identity.Name

这对User总是返回null.

public class SecurityHelper : ISecurityHelper
{
    private readonly ISecurityGroupController _securityGroupController;
    private readonly IUserController _userController;
    private readonly IEmployeeController _employeeController;
    private readonly IFieldPermissionController _fieldPermissionController;
    private readonly IOACController _oacController;

    public SecurityHelper(ISecurityGroupController securityGroupController,IUserController userController,IEmployeeController employeeController,IFieldPermissionController fieldPermissionController,IOACController oacController)
    {
        _securityGroupController = securityGroupController;
        _userController = userController;
        _employeeController = employeeController;
        _fieldPermissionController = fieldPermissionController;
        _oacController = oacController;
    }

    // ... other methods

    public User GetCurrentUser()
    {
        User user = _userController.GetByAccountName(HttpContext.Current.GetOwinContext().Request.User.Identity.Name);
        if (user != null)
        {
            List<OAC> memberships = _oacController.GetMemberships(user.SourceId).ToList();
            if (IsTestModeEnabled() && ((user.OACMemberships != null && user.OACMemberships.Count == 0) || user.OACMemberships == null))
            {
                user.OACMemberships = memberships;
            }
            else if (!IsTestModeEnabled())
            {
                user.OACMemberships = memberships;
            }
        }

        return user;
    }
}

解决方法

注意,将是以下代码,其基本上将承载令牌存储在本地存储器中并将其附加到头部.这显然比这更多,包括表单和实际的服务器认证系统,但这应该给你一个体面的开始.

服务器组件：

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        ConfigureOAuth(app);
    //Rest of code is here;
    }

    public void ConfigureOAuth(IAppBuilder app)
    {
        OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true,TokenEndpointPath = new PathString("/token"),AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),Provider = new SimpleAuthorizationServerProvider()
        };

        // Token Generation
        app.USEOAuthAuthorizationServer(OAuthServerOptions);
        app.USEOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());

    }
}

和以下客户端代码：

'use strict';
app.factory('authService',['$http','$q','localStorageService',function ($http,$q,localStorageService) {

    var serviceBase = 'http://ngauthenticationapi.azurewebsites.net/';
    var authServiceFactory = {};

    var _authentication = {
        isAuth: false,userName : ""
    };

    var _saveRegistration = function (registration) {

        _logOut();

        return $http.post(serviceBase + 'api/account/register',registration).then(function (response) {
            return response;
        });

    };

    var _login = function (loginData) {

        var data = "grant_type=password&username=" + loginData.userName + "&password=" + loginData.password;

        var deferred = $q.defer();

        $http.post(serviceBase + 'token',data,{ headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }).success(function (response) {

            localStorageService.set('authorizationData',{ token: response.access_token,userName: loginData.userName });

            _authentication.isAuth = true;
            _authentication.userName = loginData.userName;

            deferred.resolve(response);

        }).error(function (err,status) {
            _logOut();
            deferred.reject(err);
        });

        return deferred.promise;

    };

    var _logOut = function () {

        localStorageService.remove('authorizationData');

        _authentication.isAuth = false;
        _authentication.userName = "";

    };

    var _fillAuthData = function () {

        var authData = localStorageService.get('authorizationData');
        if (authData)
        {
            _authentication.isAuth = true;
            _authentication.userName = authData.userName;
        }

    }

    authServiceFactory.saveRegistration = _saveRegistration;
    authServiceFactory.login = _login;
    authServiceFactory.logOut = _logOut;
    authServiceFactory.fillAuthData = _fillAuthData;
    authServiceFactory.authentication = _authentication;

    return authServiceFactory;
}]);

随着

'use strict';
app.factory('authInterceptorService',['$q','$location',function ($q,$location,localStorageService) {

    var authInterceptorServiceFactory = {};

    var _request = function (config) {

        config.headers = config.headers || {};

        var authData = localStorageService.get('authorizationData');
        if (authData) {
            config.headers.Authorization = 'Bearer ' + authData.token;
        }

        return config;
    }

    var _responseError = function (rejection) {
        if (rejection.status === 401) {
            $location.path('/login');
        }
        return $q.reject(rejection);
    }

    authInterceptorServiceFactory.request = _request;
    authInterceptorServiceFactory.responseError = _responseError;

    return authInterceptorServiceFactory;
}]);
