c# - Azure AD Open ID Connect OAuth 2.0 in ASP.NET Web APP and Web API 无限重定向循环

Question

ASP.NET Web 应用程序可从任何 Azure Active Directory (Azure AD) 实例登录个人帐户以及工作和学校帐户。

OWIN 中间件 NuGet 包

Install-Package Microsoft.Owin.Security.OpenIdConnect
Install-Package Microsoft.Owin.Security.Cookies
Install-Package Microsoft.Owin.Host.SystemWeb

OWIN 创业类 OWIN 中间件使用在托管进程初始化时运行的启动类。在本快速入门中，startup.cs 文件位于根文件夹中。以下代码显示了本快速入门使用的参数

public void Configuration(IAppBuilder app)
{
    app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

    app.UseCookieAuthentication(new CookieAuthenticationOptions());
    app.UseOpenIdConnectAuthentication(
        new OpenIdConnectAuthenticationOptions
        {
            // Sets the ClientId, authority, RedirectUri as obtained from web.config
            ClientId = clientId,
            Authority = authority,
            RedirectUri = redirectUri,
            // PostLogoutRedirectUri is the page that users will be redirected to after sign-out. In this case, it is using the home page
            PostLogoutRedirectUri = redirectUri,
            Scope = OpenIdConnectScope.OpenIdProfile,
            // ResponseType is set to request the id_token - which contains basic information about the signed-in user
            ResponseType = OpenIdConnectResponseType.IdToken,
            // ValidateIssuer set to false to allow personal and work accounts from any organization to sign in to your application
            // To only allow users from a single organizations, set ValidateIssuer to true and 'tenant' setting in web.config to the tenant name
            // To allow users from only a list of specific organizations, set ValidateIssuer to true and use ValidIssuers parameter
            TokenValidationParameters = new TokenValidationParameters()
            {
                ValidateIssuer = false // Simplification (see note below)
            },
            // OpenIdConnectAuthenticationNotifications configures OWIN to send notification of failed authentications to OnAuthenticationFailed method
            Notifications = new OpenIdConnectAuthenticationNotifications
            {
                AuthenticationFailed = OnAuthenticationFailed
            }
        }
    );
}

ASP.NET MVC/Web API

//You can force a user to sign in by requesting an authentication challenge in your controller:
public void SignIn()
{
    if (!Request.IsAuthenticated)
    {
        HttpContext.GetOwinContext().Authentication.Challenge(
            new AuthenticationProperties{ RedirectUri = "/" },
            OpenIdConnectAuthenticationDefaults.AuthenticationType);
    }
}

ASP.NET Web 表单:

 protected void Login_click(object sender, EventArgs e)
        {
            if (!Request.IsAuthenticated)
            {
                HttpContext.Current.GetOwinContext().Authentication.Challenge(
                    new AuthenticationProperties { RedirectUri = "/" },
                    OpenIdConnectAuthenticationDefaults.AuthenticationType);
            }
        }

该问题已在 ASP.NET core 和新版本的 Katana Owin for ASP.NET 中得到修复。要解决此问题，您可以升级应用程序以使用 ASP.NET Core。如果您必须继续留在 ASP.NET，请执行以下操作:

将应用程序的 Microsoft.Owin.Host.SystemWeb 包更新为至少版本 3.1.0.0 并且修改您的代码以使用新的 cookie 管理器类之一，例如如下所示:

app.UseCookieAuthentication(new CookieAuthenticationOptions 
{ 
    AuthenticationType = "Cookies", 
    CookieManager = new Microsoft.Owin.Host.SystemWeb.SystemWebChunkingCookieManager() 
});
