题记:在ASP.NET 5负虽持续可以沿用ASP.NET
Identity来做证授权,不过呢得很轻集成支持标准协议的老三着服务,比如Azure
Active Directory。

实际上,在ASP.NET
5惨遭集成AzureAD,利用该进展求证和授权,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蒙受移植了集成OpenId
Connect的OWIN中间件。所以,只要在ASP.NET
5品类蒙引用”Microsoft.AspNet.Authentication.OpenIdConnect”这个包,并科学配置AzureAD的连天信息,就可死易之拓集成。

大概步骤如下:

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的中件:

"Microsoft.AspNet.Authentication.OpenIdConnect": "1.0.0-*"

3,在Startup中之ConfigureServices方法中添加:

// OpenID Connect Authentication Requires Cookie Auth
services.Configure<ExternalAuthenticationOptions>(options =>
{
    options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
});

4,在Startup中的Configure方法中添加:

// 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");
    }
}

以上代码也得交自我Fork的完全示例项目面临找到:https://github.com/heavenwing/WebApp-OpenIdConnect-AspNet5

一经您赶上添加了 [Authorize]
,但是不能自动转至登录页面的气象,那么需要:

app.UseOpenIdConnectAuthentication(options => {
    options.AutomaticAuthentication = true;
});
