使用 ASP.NET Core 2.0，我尝试实现以下目标：
- 通过 Azure AD 进行身份验证（注册应用程序）
- Custom JWT as the authentication scheme to
- 使 Web 应用程序身份验证能够跨服务器/实例工作
- 能够保存承载以使用桌面客户端登录
- 拥有自定义身份存储来引入自定义角色、策略等。
所有这些部分都有工作示例，但是在尝试将它们结合起来时我偶然发现了一些问题。
Web Api + Azure Ad Auth 示例使用 JWT 令牌进行身份验证，但没有用于验证或创建令牌的逻辑。它也没有登录/注销的逻辑，但这看起来很合理，它只是 Api。
下面是 Web Api 示例代码的快速提醒：
AzureAdAuthenticationBuilderExtensions.cs
using System;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Options;
namespace Microsoft.AspNetCore.Authentication
{
public static class AzureAdServiceCollectionExtensions
{
public static AuthenticationBuilder AddAzureAdBearer(this AuthenticationBuilder builder)
=> builder.AddAzureAdBearer(_ => { });
public static AuthenticationBuilder AddAzureAdBearer(this AuthenticationBuilder builder, Action<AzureAdOptions> configureOptions)
{
builder.Services.Configure(configureOptions);
builder.Services.AddSingleton<IConfigureOptions<JwtBearerOptions>, ConfigureAzureOptions>();
builder.AddJwtBearer();
return builder;
}
private class ConfigureAzureOptions: IConfigureNamedOptions<JwtBearerOptions>
{
private readonly AzureAdOptions _azureOptions;
public ConfigureAzureOptions(IOptions<AzureAdOptions> azureOptions)
{
_azureOptions = azureOptions.Value;
}
public void Configure(string name, JwtBearerOptions options)
{
options.Audience = _azureOptions.ClientId;
options.Authority = $"{_azureOptions.Instance}{_azureOptions.TenantId}";
}
public void Configure(JwtBearerOptions options)
{
Configure(Options.DefaultName, options);
}
}
}
}
摘录启动.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddAzureAdBearer(options => Configuration.Bind("AzureAd", options));
services.AddMvc();
}
另一方面，Web 应用程序 + Azure Ad 示例使用 OpenId 和 cookie，并且确实具有登录/注销逻辑：
AzureAdAuthenticationBuilderExtensions.cs
using System;
using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Options;
namespace Microsoft.AspNetCore.Authentication
{
public static class AzureAdAuthenticationBuilderExtensions
{
public static AuthenticationBuilder AddAzureAd(this AuthenticationBuilder builder)
=> builder.AddAzureAd(_ => { });
public static AuthenticationBuilder AddAzureAd(this AuthenticationBuilder builder, Action<AzureAdOptions> configureOptions)
{
builder.Services.Configure(configureOptions);
builder.Services.AddSingleton<IConfigureOptions<OpenIdConnectOptions>, ConfigureAzureOptions>();
builder.AddOpenIdConnect();
return builder;
}
private class ConfigureAzureOptions : IConfigureNamedOptions<OpenIdConnectOptions>
{
private readonly AzureAdOptions _azureOptions;
public ConfigureAzureOptions(IOptions<AzureAdOptions> azureOptions)
{
_azureOptions = azureOptions.Value;
}
public void Configure(string name, OpenIdConnectOptions options)
{
options.ClientId = _azureOptions.ClientId;
options.Authority = $"{_azureOptions.Instance}{_azureOptions.TenantId}";
options.UseTokenLifetime = true;
options.CallbackPath = _azureOptions.CallbackPath;
options.RequireHttpsMetadata = false;
}
public void Configure(OpenIdConnectOptions options)
{
Configure(Options.DefaultName, options);
}
}
}
}
摘录启动.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
sharedOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddAzureAd(options => Configuration.Bind("AzureAd", options))
.AddCookie();
services.AddMvc(options =>
{
var policy = new AuthorizationPolicyBuilder()
.RequireAuthenticatedUser()
.Build();
options.Filters.Add(new AuthorizeFilter(policy));
})
.AddRazorPagesOptions(options =>
{
options.Conventions.AllowAnonymousToFolder("/Account");
});
}
AccountController.cs
public class AccountController : Controller
{
[HttpGet]
public IActionResult SignIn()
{
var redirectUrl = Url.Page("/Index");
return Challenge(
new AuthenticationProperties { RedirectUri = redirectUrl },
OpenIdConnectDefaults.AuthenticationScheme
);
}
[HttpGet]
public IActionResult SignOut()
{
var callbackUrl = Url.Page("/Account/SignedOut", pageHandler: null, values: null, protocol: Request.Scheme);
return SignOut(
new AuthenticationProperties { RedirectUri = callbackUrl },
CookieAuthenticationDefaults.AuthenticationScheme, OpenIdConnectDefaults.AuthenticationScheme
);
}
}
我已经以某种方式合并了这两个变体，但显然它不起作用。我当然替换了CookieAuthenticationDefault with JwtBearerDefaults在登录方法中。
摘录启动.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddEntityFrameworkSqlServer().AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
sharedOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddAzureAd(options => Configuration.Bind("AzureAd", options))
.AddJwtBearer(options =>
{
options.IncludeErrorDetails = true;
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "localhost",
ValidAudience = "localhost",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("test"))
};
});
services.AddMvc(options =>
{
var policy = new AuthorizationPolicyBuilder()
.RequireAuthenticatedUser()
.Build();
options.Filters.Add(new AuthorizeFilter(policy));
})
.AddRazorPagesOptions(options =>
{
options.Conventions.AllowAnonymousToFolder("/Account");
});
}
我不完全理解不同的身份验证如何链接或相互依赖。据我了解，OpenId 在内部使用某种 JWT，但仍然存在以下问题：
- 为什么 Web Api 示例仅使用 JWT，而另一个示例则使用 OpenId 和 cookies ？
- 为什么 OpenId 示例首先不使用 JWT ？
- 自定义 JWT 可以与 OpenId 一起使用吗？
- 是否可以引入自定义身份存储，但保留用于登录的 Azure AD（以及登录名）？
如果您能为我提供一些指导，那就太好了，不需要完整的工作示例（尽管这会很棒）
