我正在尝试使用 Azure Active Directory 处理 Web 应用上的身份验证。但是,当我尝试使用 AuthorizeAttribute
进行操作时,应用程序抛出 OptionsValidationException
。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。代码如下:
添加对 Microsoft.AspNetCore.Authentication.AzureAD.UI
的包引用版本3.1.1。
启动类
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 Controller
仅使用一个 Controller 。
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“索引”操作时,您会得到异常输出:
Hello Anonymous User!
当您到达 /restricted
端点时,就会引发异常。
最佳答案
您没有提供 Microsoft.AspNetCore.Authentication.AzureAD.UI
的多个配置Azure AD 身份验证中需要,例如 Instance
, CallbackPath
。您可以修改您的代码如下:
services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
.AddAzureAD(options => Configuration.Bind("AzureAd", options));
然后在 appsettings.json
,添加吹气配置:
"AzureAd": {
"Instance": "https://login.microsoftonline.com/",
"Domain": "xxxx.onmicrosoft.com",
"TenantId": "xxxxxx-a2dd-4fde-bf8f-f75ab18b21ac",
"ClientId": "xxxxxxxxx-a9bb-4722-b615-6dcbdc646326",
"CallbackPath": "/signin-oidc"
},
当然,您应该在Azure门户中提供真实的domian/tenant/clientid并注册https://localhost:xxx/signin-oidc
作为门户中的重定向网址。
另一种方法是使用 Azure AD 身份验证模板:新建 ASP.NET Core 应用程序 --> 选择 MVC/Razor 模板 --> 更改身份验证 --> 工作或学校帐户 --> 选择您的租户,模板将有所帮助配置您的应用程序以实现 Azure AD 身份验证。
关于c# - ASP.NET Core 3.1 Azure AD 身份验证抛出 OptionsValidationException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/60178378/
