请帮助我了解来自 ASP netcore 应用程序和 netcore Kestrel 托管应用程序的 JWT 令牌验证之间的区别。
有两个应用程序使用如下源代码验证令牌:
public static IServiceCollection AddJwtToken(this IServiceCollection services, OAuthConfig config)
{
services.AddMvc();
services.AddAuthorization();
Logger.DebugFormat("AddJwtBearer authority:{0} audience:{1}", config.GetAuthority(), config.Resource);
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options => new JwtBearerOptions
{
Authority = config.GetAuthority(),
Audience = config.Resource,
});
return services;
}

它非常简单,如果从 asp net core 2.2 应用程序验证令牌,它就可以很好地工作
// in the asp.net core
var builder = WebHost.CreateDefaultBuilder(args);
builder
.UseStartup<Startup>()
.ConfigureKestrel(_ => _.ConfigureEndpoints())
.UseSerilog();

还有另一个应用程序(控制台)使用 UseKestrel
//in the console app
var builder = WebHost.CreateDefaultBuilder()
.UseNLog()
.UseKestrel(_ => _.ConfigureEndpoints())
.UseStartup<Startup>();

唯一的一个显着区别是UseKestrel控制台中的 via ConfigureKestrelfor asp.net core。
相同的源代码(和配置)用于从 Azure AD 获取令牌。请在这里找到它作为要点。它被配置为从https://login.microsoftonline.com/{tenant}/v2.0提供者获取令牌。两种情况都使用相同的令牌端点、clientid、secret 和 scope 值。
问题是AddJwtBearer在 asp.net 核心中验证令牌,而不是在控制台应用程序中。错误是
Microsoft.IdentityModel.Tokens.SecurityTokenSignatureKeyNotFoundException: IDX10501: Signature validation failed. Unable to match keys:
kid: 'BB8CeFVqyaGrGNuehJIiL4dfjzw',
token: '{"typ":"JWT","alg":"RS256","kid":"BB8CeFVqyaGrGNuehJIiL4dfjzw"}.{"aud":"2c163c99-935b-4362-ae0d-657f589f5565","iss":"https://login.microsoftonline.com/{tenantidhere}/v2.0

为什么 asp.net 核心主机验证令牌(对于第一个AddJwtBearer实现)而控制台主机失败?
谢谢

就我而言,相同的错误是由于无意中使用了从一个环境(https://dev/identity)接收并在另一环境(即 http://local/identity)中验证的令牌。

要解决此错误,我必须从 openid 提供程序加载密钥,如下所示:
Logger.DebugFormat("AddJwtBearer authority:{0} audience:{1}", config.GetAuthority(), config.Resource);
IList<string> validissuers = new List<string>()
{
config.GetAuthority(),
};
var configManager = new ConfigurationManager<OpenIdConnectConfiguration>($"{validissuers.Last()}/.well-known/openid-configuration", new OpenIdConnectConfigurationRetriever());
var openidconfig = configManager.GetConfigurationAsync().Result;
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, _ =>
{
_.TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters()
{
ValidateAudience = true,
ValidAudience = config.Resource,
ValidateIssuer = true,
ValidIssuers = new[] { config.GetAuthority() },
ValidateIssuerSigningKey = true,
IssuerSigningKeys = openidconfig.SigningKeys,
RequireExpirationTime = true,
ValidateLifetime = true,
RequireSignedTokens = true,
};
_.RequireHttpsMetadata = false;
});

它开始适用于这两种情况。但是旧AddJwtBearer实现和新实现(与密钥验证相关)有什么区别?钥匙在那里下载并使用附带的IssuerSigningKeys = openidconfig.SigningKeys,但为什么不使用自动加载.well-known/openid-configuration由AddJwtBearer中间件?
