c# - Azure AD 未在 .NET Core 3.1 中进行身份验证

Question

我正在尝试让 Azure AD 在现有应用程序中运行。我已按照说明进行操作并查看了 Microsoft 网站 ( https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-v2-aspnet-core-webapp ) 中的示例代码，但没有成功。示例代码使用.NET Core 2.1。我可以让它与 .NET Core 2.1 一起工作，但 3.1 由于几个原因而感到不舒服。

1. 与示例代码相比，需要将 EnableEndpointRouting 设置为 false。
2. 与示例代码相比，我尝试删除 AddMvc 上设置的兼容性版本，并尝试将其设置为 3.0。

当我在 .NET Core 3.1 中运行它时，它所做的只是加载页面，并且从不调用/执行身份验证，并且表现得就像 Controller 上没有 Authorize 标记一样。

我在 Controller 的类级别上有一个授权标签。

启动.cs:

...
            services.Configure<CookiePolicyOptions>(options =>
            {
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
                .AddAzureAD(options => Configuration.Bind("AzureAd", options));

            services.Configure<OpenIdConnectOptions>(AzureADDefaults.OpenIdScheme, options =>
            {
                options.Authority = options.Authority + "/v2.0/";
                options.TokenValidationParameters.ValidateIssuer = false;
            });

            services.AddMvc(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new AuthorizeFilter(policy));
                options.EnableEndpointRouting = false;
            });

然后在下面的配置功能中:

...
app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseAuthentication();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });

然后在我的 appsettings.json 中我有:

{
  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "Domain": "domain.onmicrosoft.com",
    "TenantId": "guid",
    "ClientId": "guid",
    "CallbackPath": "/signin-oidc"
  },
...

我的问题是为什么它会将请求视为未经身份验证？我还尝试使用 UseAuthentication 下面的 UseAuthorization。

谢谢!

Answer 1

根据我的测试，如果您想为.net core 3.1 Web应用配置Azure AD，请引用以下步骤

1. Register Azure AD web application

2. 配置应用程序

   a.安装 SDK Microsoft.AspNetCore.Authentication.AzureAD.UI

     <Project Sdk="Microsoft.NET.Sdk.Web">

      <PropertyGroup>
        <TargetFramework>netcoreapp3.1</TargetFramework>
      </PropertyGroup>

      <ItemGroup>
        <PackageReference Include="Microsoft.AspNetCore.Authentication.AzureAD.UI" Version="3.1.1" />
      </ItemGroup>

    </Project>

b.更新appsettings.json

      "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "Domain": "domain.onmicrosoft.com",
    "TenantId": "guid",
    "ClientId": "guid",
    "CallbackPath": "/signin-oidc"
  },
...  

c.更新startup.cs

• 在ConfigureServices函数中添加以下代码

  public void ConfigureServices(IServiceCollection services)
  {
      services.Configure<CookiePolicyOptions>(options =>
      {
  
          options.CheckConsentNeeded = context => true;
          options.MinimumSameSitePolicy = SameSiteMode.Unspecified;
  
      });
      services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
           .AddAzureAD(options => Configuration.Bind("AzureAd", options));
  
      services.Configure<OpenIdConnectOptions>(AzureADDefaults.OpenIdScheme, options =>
      {
          options.Authority = options.Authority + "/v2.0/";
          options.TokenValidationParameters.ValidateIssuer = false;
      });
      services.AddControllersWithViews(options =>
      {
          var policy = new AuthorizationPolicyBuilder()
              .RequireAuthenticatedUser()
              .Build();
          options.Filters.Add(new AuthorizeFilter(policy));
      });
      services.AddRazorPages();
  }
  

• 在Configure函数中添加以下代码

  public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
     {
        ...
         app.UseHttpsRedirection();
         app.UseStaticFiles();

         app.UseRouting();

         app.UseCookiePolicy();
         app.UseAuthentication();
         app.UseAuthorization();

         app.UseEndpoints(endpoints =>
         {
             endpoints.MapControllerRoute(
                 name: "default",
                 pattern: "{controller=Home}/{action=Index}/{id?}");
         });
     }
