本文给大家介绍的是在ASP.NET 5中使用AzureAD实现单点登录的方法和示例,有需要的小伙伴可以参考下。
题记:在ASP.NET 5中虽然继续可以沿用ASP.NET Identity来做验证授权,不过也可以很容易集成支持标准协议的第三方服务,比如Azure Active Directory。
其实,在ASP.NET 5中集成AzureAD,利用其进行验证和授权,是非常简单的。因为:首先Azure Active Directory提供了OAuth2.0、OpenId Connect 1.0、SAML和WS-Federation 1.2标准协议接口;其次微软在ASP.NET 5中移植了集成OpenId Connect的OWIN中间件。所以,只要在ASP.NET 5项目中引用"Microsoft.AspNet.Authentication.OpenIdConnect"这个包,并正确配置AzureAD的连接信息,就可以很容易的进行集成。
大致步骤如下:
1,在config.json文件中添加AzureAD的配置信息:
- "AzureAd": {
- "ClientId": "[Enter the clientId of your application as obtained from portal, e.g. ba74781c2-53c2-442a-97c2-3d60re42f403]",
- "Tenant": "[Enter the name of your tenant, e.g. contoso.onmicrosoft.com]",
- "AadInstance": "https://login.microsoftonline.com/{0}", // This is the public instance of Azure AD
- "PostLogoutRedirectUri": https://localhost:44322/
- }
2,修改project.json,引入OpenIdConnect的中间件:
- "Microsoft.AspNet.Authentication.OpenIdConnect": "1.0.0-*"
3,在Startup中的ConfigureServices方法里面添加:
- // OpenID Connect Authentication Requires Cookie Auth
- services.Configure<ExternalAuthenticationOptions>(options =>
- {
- options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
- });
4,在Startup中的Configure方法里面添加:
- // Configure the OWIN Pipeline to use Cookie Authentication
- app.UseCookieAuthentication(options =>
- {
- // By default, all middleware are passive/not automatic. Making cookie middleware automatic so that it acts on all the messages.
- options.AutomaticAuthentication = true;
- });
- // Configure the OWIN Pipeline to use OpenId Connect Authentication
- app.UseOpenIdConnectAuthentication(options =>
- {
- options.ClientId = Configuration.Get("AzureAd:ClientId");
- options.Authority = String.Format(Configuration.Get("AzureAd:AadInstance"), Configuration.Get("AzureAd:Tenant"));
- options.PostLogoutRedirectUri = Configuration.Get("AzureAd:PostLogoutRedirectUri");
- options.Notifications = new OpenIdConnectAuthenticationNotifications
- {
- AuthenticationFailed = OnAuthenticationFailed,
- };
- });
5,Startup的OnAuthenticationFailed方法为:
- private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
- {
- notification.HandleResponse();
- notification.Response.Redirect("/Home/Error?message=" + notification.Exception.Message);
- return Task.FromResult(0);
- }
6,添加一个名为AccountController的Controller:
- public class AccountController : Controller
- {
- // GET: /Account/Login
- [HttpGet]
- public IActionResult Login()
- {
- if (Context.User == null || !Context.User.Identity.IsAuthenticated)
- return new ChallengeResult(OpenIdConnectAuthenticationDefaults.AuthenticationScheme, new AuthenticationProperties { RedirectUri = "/" });
- return RedirectToAction("Index", "Home");
- }
- // GET: /Account/LogOff
- [HttpGet]
- public IActionResult LogOff()
- {
- if (Context.User.Identity.IsAuthenticated)
- {
- Context.Authentication.SignOut(CookieAuthenticationDefaults.AuthenticationScheme);
- Context.Authentication.SignOut(OpenIdConnectAuthenticationDefaults.AuthenticationScheme);
- }
- return RedirectToAction("Index", "Home");
- }
- }
以上代码也可以到我Fork的完整示例项目中找到:https://github.com/heavenwing/WebApp-OpenIdConnect-AspNet5
【更新:2015-07-16】
如果你遇到添加了 [Authorize] ,但是不能自动转到登录页面的情况,那么需要:
- app.UseOpenIdConnectAuthentication(options => {
- options.AutomaticAuthentication = true;
- });
