在ASP.Net中,可以使用Identity Server来实现身份验证和授权的功能。当用户注销时,可能会遇到“ASP.Net身份验证属性在从Identity Server实例注销时未设置”的问题。以下是一个解决方法的代码示例:
public void ConfigureServices(IServiceCollection services)
{
// 注册Identity Server
services.AddIdentityServer()
.AddInMemoryClients(Config.Clients)
.AddInMemoryIdentityResources(Config.IdentityResources)
.AddInMemoryApiResources(Config.ApiResources)
.AddTestUsers(Config.Users)
.AddDeveloperSigningCredential();
// 其他配置...
}
public static class Config
{
public static IEnumerable Clients =>
new List
{
new Client
{
ClientId = "client",
AllowedGrantTypes = GrantTypes.ClientCredentials,
ClientSecrets =
{
new Secret("secret".Sha256())
},
AllowedScopes = { "api" }
}
};
public static IEnumerable IdentityResources =>
new List
{
new IdentityResources.OpenId(),
new IdentityResources.Profile(),
new IdentityResources.Email()
};
public static IEnumerable ApiResources =>
new List
{
new ApiResource("api", "My API")
};
public static List Users =>
new List
{
new TestUser
{
SubjectId = "1",
Username = "alice",
Password = "password"
}
};
}
public class AccountController : Controller
{
private readonly IIdentityServerInteractionService _interaction;
public AccountController(IIdentityServerInteractionService interaction)
{
_interaction = interaction;
}
public async Task Logout(string logoutId)
{
var logoutRequest = await _interaction.GetLogoutContextAsync(logoutId);
if (string.IsNullOrEmpty(logoutRequest.PostLogoutRedirectUri))
{
return RedirectToAction("Index", "Home");
}
return Redirect(logoutRequest.PostLogoutRedirectUri);
}
}
以上代码示例演示了如何使用Identity Server进行身份验证和注销操作,并解决了“ASP.Net身份验证属性在从Identity Server实例注销时未设置”的问题。请根据实际情况进行相应调整和配置。
