我正在尝试使用 Azure Active Directory 处理 Web 应用程序上的身份验证。然而，当我尝试用AuthorizeAttribute https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.authorization.authorizeattribute?view=aspnetcore-3.1，应用程序抛出一个OptionsValidationException https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.options.optionsvalidationexception?view=dotnet-plat-ext-3.1。出现以下错误：
Microsoft.Extensions.Options.OptionsValidationException: The 'Instance' option must be provided.

我不知道是什么原因造成的。这是代码：
添加包引用Microsoft.AspNetCore.Authentication.AzureAD.UI https://www.nuget.org/packages/Microsoft.AspNetCore.Authentication.AzureAD.UI/版本 3.1.1。

public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(defaultScheme: AzureADDefaults.AuthenticationScheme)
.AddAzureAD(options =>
{
options.ClientId = "<client_id_goes_here>";
options.TenantId = "<tenant_id_goes_here>";
});
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseDeveloperExceptionPage();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints => endpoints.MapControllers());
}
家庭控制器
仅使用一个控制器。
public class HomeController : Controller
{
[Route("")]
[AllowAnonymous]
public string Index() => "Hello Anonymous User!";
[Route("restricted")]
[Authorize]
public string Restricted() => $"Hello, {User.Identity.Name}.";
}
当您运行应用程序并点击 Index 操作时，您将获得预期的输出：
Hello Anonymous User!
当你击中/restricted端点，然后抛出异常。
