我正在尝试使用IdentityServer4实现我自己的OAuth服务器,到目前为止除了注销外一切正常。
我不使用Microsoft Identity,因为我已经拥有一个WebApi的现有WebApp,它正在处理与用户相关的CRUD操作。因此,我使用现有数据库来获取用户并验证其用户名和PW。如果验证成功,我的验证方法将返回“AuthenticatedUser”类型的对象(这是我制作的UtilityClass)。
编辑我的客户端是一个Xamarin应用程序,并使用IdentityModel.OidcClient2进行登录。我正在使用UWP平台 Edit 进行测试,该平台使用WebAuthenticationBroker进行登录/注销调用。
我使用的代码是QuickStart UI示例中的代码,只需稍加修改即可验证现有数据库中的用户: 编辑现在我明确地创建了Claims,ClaimsIdentity,并尽可能地添加了CookieAuthenticationDefaults.AuthenticationScheme。
//my method for user validation
AuthenticatedUser user = await _userService.ValidateCredentials(model.Username, model.Password);
//rest of login code from quickstart ui
if (user != null)
{
await _events.RaiseAsync(new UserLoginSuccessEvent(user.FirstName, user.Id.ToString(), user.FirstName));
// only set explicit expiration here if user chooses "remember me".
// otherwise we rely upon expiration configured in cookie middleware.
AuthenticationProperties props = null;
if (AccountOptions.AllowRememberLogin && model.RememberLogin)
{
props = new AuthenticationProperties
{
IsPersistent = true,
ExpiresUtc = DateTimeOffset.UtcNow.Add(AccountOptions.RememberMeLoginDuration)
};
};
//things we know about the user that we wish to store on the cookie
var claims = new List<Claim>
{
new Claim(JwtClaimTypes.Role, user.RoleId.ToString()),
new Claim(JwtClaimTypes.Name, user.FirstName + " " + user.LastName),
new Claim(JwtClaimTypes.Subject, user.Id.ToString())
};
var userIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
ClaimsPrincipal principal = new ClaimsPrincipal(userIdentity);
//set the cookie using the SignInAsync method
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, props);
// issue authentication cookie with subject ID and username
await HttpContext.SignInAsync(user.Id.ToString(), user.FirstName, props);
//....
到目前为止,这似乎运作良好。当登录失败时,我无法访问受保护的Api,如果登录成功,我会获得一个带有我请求的声明的AccessToken,并且我可以按预期访问受保护的Api方法。
当我调用注销端点(通过对端点的HTTP请求完成,提供id_token_hint作为查询参数)时,由于某种原因,用户未经过身份验证 - 因此我的用户永远不会通过调用HttpContext.SignOutAsync来注销( )。
if (User?.Identity.IsAuthenticated == true) //always evaluates to false?! why?
{
// delete local authentication cookie
await HttpContext.SignOutAsync();
// raise the logout event
await _events.RaiseAsync(new UserLogoutSuccessEvent(User.GetSubjectId(), User.GetDisplayName()));
}
编辑使用WebAuthenticationBroker而不是简单的HTTP请求来调用注销端点后,控制台会记录“XamarinApp”已注销的状态。即使从未调用过HttpContext.SignOutAsync()这是什么意思?我怀疑这是好的,但是应用程序表现得像我想要的那样,例如我可以用新用户登录。

编辑据我所知,这可能与我的Xamarin客户端和Cookie有关。我找到了有关如何配置MVC客户端,IDSVR4和Cookie中间件的教程,但没有关于本机应用程序,IDSVR4和Cookie中间件的任何内容。
IDSVR4(或特别是注销)应该如何与非MVC客户端和IdentityModel.OidcClient一起使用?
答案 0 :(得分:0)
最后我找到了原因。在QuickstartUI示例中,仅当用户选择“记住我”选项时,类“ AccountConteroller.cs”才设置Explicit Expiration。我删除了if条件,并最终正确存储了身份验证Cookie,注销后我的用户不再为null,一切都很好。
class AccountController
...
AuthenticationProperties props = null;
//ALWAYS SET EXPLICIT EXPIRATION, SO COOKIE CAN BE DELETED WHEN LOGGING OUT
//if (AccountOptions.AllowRememberLogin && model.RememberLogin)
//{
props = new AuthenticationProperties
{
IsPersistent = true,
ExpiresUtc = DateTimeOffset.UtcNow.Add(AccountOptions.RememberMeLoginDuration)
};
//};
