在使用Identity Server作Identity Provider的时候，我们在NetCore的ConfigureServices((IServiceCollection services))方法中,常需要指定options的Authority，如下代码所示：
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
//
#region MVC client
//关闭了 JWT 身份信息类型映射
//这样就允许 well-known 身份信息（比如，“sub” 和 “idp”）无干扰地流过。
//这个身份信息类型映射的“清理”必须在调用 AddAuthentication()之前完成
JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
services.AddAuthentication(options =>
{
options.DefaultScheme = "Cookies";
options.DefaultChallengeScheme = "oidc";
})
.AddCookie("Cookies")
.AddOpenIdConnect("oidc", options =>
{
options.Authority = "http://localhost:5001";
options.RequireHttpsMetadata = false;
options.ClientId = "code_client";
//Client secret
options.ClientSecret = "511536EF-F270-4058-80CA-1C89C192F69A".ToString();
//code方式
options.ResponseType = "code";
//Scope可以理解为申请何种操作范围
options.Scope.Add("code_scope1"); //添加授权资源
options.SaveTokens = true;
options.GetClaimsFromUserInfoEndpoint = true;
});
#endregion
services.ConfigureNonBreakingSameSiteCookies();
}
其中options.Authority = “http://localhost:5001″需要设置，如果把它注释掉，则会报如下的错误，从这个异常看得出来，应该是Authority没有设置：
那么为什么我们一定要设置.Authority 呢？我们一步一步来看看：
1.在调用services.AddOpenIdConnect方法时，实质调用的是OpenIdConnectExtensions静态类的AddOpenIdConnect静态方法，如下所示：
public static AuthenticationBuilder AddOpenIdConnect(this AuthenticationBuilder builder, string authenticationScheme, string? displayName, Action<OpenIdConnectOptions> configureOptions)
{
builder.Services.TryAddEnumerable(ServiceDescriptor.Singleton<IPostConfigureOptions<OpenIdConnectOptions>, OpenIdConnectPostConfigureOptions>());
return builder.AddRemoteScheme<OpenIdConnectOptions, OpenIdConnectHandler>(authenticationScheme, displayName, configureOptions);
}
2.从上面的代码看得出，实际上调用的是AuthenticationBuilder的AddRemoteScheme扩展方法，如下所示：
/// <summary>
/// Adds a <see cref="AuthenticationScheme"/> which can be used by <see cref="IAuthenticationService"/>.
/// </summary>
/// <typeparam name="TOptions">The <see cref="AuthenticationSchemeOptions"/> type to configure the handler."/>.</typeparam>
/// <typeparam name="THandler">The <see cref="AuthenticationHandler{TOptions}"/> used to handle this scheme.</typeparam>
/// <param name="authenticationScheme">The name of this scheme.</param>
/// <param name="displayName">The display name of this scheme.</param>
/// <param name="configureOptions">Used to configure the scheme options.</param>
/// <returns>The builder.</returns>
public virtual AuthenticationBuilder AddScheme<TOptions, [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)]THandler>(string authenticationScheme, string? displayName, Action<TOptions>? configureOptions)
where TOptions : AuthenticationSchemeOptions, new()
where THandler : AuthenticationHandler<TOptions>
=> AddSchemeHelper<TOptions, THandler>(authenticationScheme, displayName, configureOptions);
private AuthenticationBuilder AddSchemeHelper<TOptions, [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)]THandler>(string authenticationScheme, string? displayName, Action<TOptions>? configureOptions)
where TOptions : AuthenticationSchemeOptions, new()
where THandler : class, IAuthenticationHandler
{
Services.Configure<AuthenticationOptions>(o =>
{
//注册Scheme对应的HandlerType
o.AddScheme(authenticationScheme, scheme => {
scheme.HandlerType = typeof(THandler);
scheme.DisplayName = displayName;
});
});
if (configureOptions != null)
{
Services.Configure(authenticationScheme, configureOptions);
}
//Options验证
Services.AddOptions<TOptions>(authenticationScheme).Validate(o => {
o.Validate(authenticationScheme);
return true;
});
Services.AddTransient<THandler>();
return this;
}
看得出来，实际上调用的是AddSchemeHelper方法，在这个方法里，有一个很重要的Options验证：
Services.AddOptions<TOptions>(authenticationScheme).Validate(o => { o.Validate(authenticationScheme); return true; });
在这里需要对AuthenticationSchemeOptions进行验证
3.上一步的Options验证中实际上调用的是OpenIdConnectOptions类的Validate方法，如下所示：
/// <summary>
/// Check that the options are valid. Should throw an exception if things are not ok.
/// </summary>
public override void Validate()
{
base.Validate();
if (MaxAge.HasValue && MaxAge.Value < TimeSpan.Zero)
{
throw new ArgumentOutOfRangeException(nameof(MaxAge), MaxAge.Value, "The value must not be a negative TimeSpan.");
}
if (string.IsNullOrEmpty(ClientId))
{
throw new ArgumentException("Options.ClientId must be provided", nameof(ClientId));
}
if (!CallbackPath.HasValue)
{
throw new ArgumentException("Options.CallbackPath must be provided.", nameof(CallbackPath));
}
//如果Authority没有设置,则报下面这个异常
if (ConfigurationManager == null)
{
throw new InvalidOperationException($"Provide {nameof(Authority)}, {nameof(MetadataAddress)}, "
+ $"{nameof(Configuration)}, or {nameof(ConfigurationManager)} to {nameof(OpenIdConnectOptions)}");
}
}
从这里看得出来，如果ConfigurationManager为空，则就会报前面中的异常了，所以异常就是这么来的。
4.那么为什么ConfigurationManager为空呢？我们回顾OpenIdConnectExtensions的AddOpenIdConnect方法：
public static AuthenticationBuilder AddOpenIdConnect(this AuthenticationBuilder builder, string authenticationScheme, string? displayName, Action<OpenIdConnectOptions> configureOptions)
{
builder.Services.TryAddEnumerable(ServiceDescriptor.Singleton<IPostConfigureOptions<OpenIdConnectOptions>, OpenIdConnectPostConfigureOptions>());
return builder.AddRemoteScheme<OpenIdConnectOptions, OpenIdConnectHandler>(authenticationScheme, displayName, configureOptions);
} 看得出AuthenticationBuilder的Services添加了一个名为OpenIdConnectPostConfigureOptions的单例服务： builder.Services.TryAddEnumerable(ServiceDescriptor.Singleton<IPostConfigureOptions<OpenIdConnectOptions>, OpenIdConnectPostConfigureOptions>());
继续看下OpenIdConnectPostConfigureOptions的源码：
/// <summary>
/// Invoked to post configure a TOptions instance.
/// </summary>
/// <param name="name">The name of the options instance being configured.</param>
/// <param name="options">The options instance to configure.</param>
public void PostConfigure(string name, OpenIdConnectOptions options)
{
options.DataProtectionProvider = options.DataProtectionProvider ?? _dp;
if (string.IsNullOrEmpty(options.SignOutScheme))
{
options.SignOutScheme = options.SignInScheme;
}
if (options.StateDataFormat == null)
{
var dataProtector = options.DataProtectionProvider.CreateProtector(
typeof(OpenIdConnectHandler).FullName!, name, "v1");
options.StateDataFormat = new PropertiesDataFormat(dataProtector);
}
if (options.StringDataFormat == null)
{
var dataProtector = options.DataProtectionProvider.CreateProtector(
typeof(OpenIdConnectHandler).FullName!,
typeof(string).FullName!,
name,
"v1");
options.StringDataFormat = new SecureDataFormat<string>(new StringSerializer(), dataProtector);
}
if (string.IsNullOrEmpty(options.TokenValidationParameters.ValidAudience) && !string.IsNullOrEmpty(options.ClientId))
{
options.TokenValidationParameters.ValidAudience = options.ClientId;
}
if (options.Backchannel == null)
{
options.Backchannel = new HttpClient(options.BackchannelHttpHandler ?? new HttpClientHandler());
options.Backchannel.DefaultRequestHeaders.UserAgent.ParseAdd("Microsoft ASP.NET Core OpenIdConnect handler");
options.Backchannel.Timeout = options.BackchannelTimeout;
options.Backchannel.MaxResponseContentBufferSize = 1024 * 1024 * 10; // 10 MB
}
if (options.ConfigurationManager == null)
{
if (options.Configuration != null)
{
options.ConfigurationManager = new StaticConfigurationManager<OpenIdConnectConfiguration>(options.Configuration);
}
else if (!(string.IsNullOrEmpty(options.MetadataAddress) && string.IsNullOrEmpty(options.Authority)))
{
if (string.IsNullOrEmpty(options.MetadataAddress) && !string.IsNullOrEmpty(options.Authority))
{
options.MetadataAddress = options.Authority;
if (!options.MetadataAddress.EndsWith("/", StringComparison.Ordinal))
{
options.MetadataAddress += "/";
}
options.MetadataAddress += ".well-known/openid-configuration";
}
if (options.RequireHttpsMetadata && !(options.MetadataAddress?.StartsWith("https://", StringComparison.OrdinalIgnoreCase) ?? false))
{
throw new InvalidOperationException("The MetadataAddress or Authority must use HTTPS unless disabled for development by setting RequireHttpsMetadata=false.");
}
options.ConfigurationManager = new ConfigurationManager<OpenIdConnectConfiguration>(options.MetadataAddress, new OpenIdConnectConfigurationRetriever(),
new HttpDocumentRetriever(options.Backchannel) { RequireHttps = options.RequireHttpsMetadata })
{
RefreshInterval = options.RefreshInterval,
AutomaticRefreshInterval = options.AutomaticRefreshInterval,
};
}
}
}
注意看两个if语句，才发现OpenIdConnectOptions的Authority和MetadataAddress在都没有设置的情况下，OpenIdConnectOptions的ConfigurationManager为空！
所以，从上文看得出，如果不设置OpenIdConnectOptions的Authority，那么无法进行OpenIdConnect认证哦！
