C# aspnet core 2.0的强类型OpenIdConnectOptions

我试图理解在构造OpenIDConnectOptions时如何利用强类型

我知道我们可以使用POCO类和IOptions实现为appsettings和其他项实现强类型，并从控制器构造函数访问这些项，但在这里，我的问题是在控制器部分之前。在运行时启动时失败

首先，我有startup.configureservice和：

services.AddAzureADOpenIDAuthentication(Configuration);

我有用于AddAzureADOpenIDAuthentication的IServiceCollection的扩展方法，如：

services.Configure<AzureADOptions>(configuration.GetSection("Authentication:AzureAd"));

        services.AddSingleton<IOptionsMonitor<OpenIdConnectOptions>, AzureADOpenIdConnectOptionsSetup>();

        services.AddAuthentication(auth =>
        {
            auth.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
            auth.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            auth.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
        })
        .AddCookie().AddOpenIdConnect();

        return services;

services.Configure（configuration.GetSection（“Authentication:AzureAd”）；
services.AddSingleton（）；
services.AddAuthentication（auth=>
{
auth.DefaultChallengeScheme=OpenIdConnectDefaults.AuthenticationScheme；
auth.DefaultAuthenticateScheme=CookieAuthenticationDefaults.AuthenticationScheme；
auth.DefaultSignenscheme=CookieAuthenticationDefaults.AuthenticationScheme；
})
.AddCookie（）.AddOpenIdConnect（）；
返回服务；

最后，我使用以下IOptionsMonitor实现了AzureADOpenIdConnectionOptions设置：

public class AzureADOpenIdConnectOptionsSetup : IOptionsMonitor<OpenIdConnectOptions>
{
    public OpenIdConnectOptions CurrentValue { get; set; }

    public AzureADOpenIdConnectOptionsSetup(IOptionsMonitor<AzureADOptions> azureADOptions)
    {
        CurrentValue = new OpenIdConnectOptions();

        CurrentValue.ClientId = azureADOptions.CurrentValue.ClientId;
        CurrentValue.Authority = azureADOptions.CurrentValue.Authority;
        CurrentValue.CallbackPath = azureADOptions.CurrentValue.CallbackPath;
    }

    public OpenIdConnectOptions Get(string name)
    {
        return CurrentValue;
    }

    public IDisposable OnChange(Action<OpenIdConnectOptions, string> listener)
    {
        throw new NotImplementedException();
    }
}

    public static class AzureAdAuthenticationBuilderExtensions
{      
    public static AuthenticationBuilder AddAzureADOpenIDAuthentication(this AuthenticationBuilder builder, IConfiguration configuration)
    {
        builder.Services.Configure<AzureAdOptions>(configuration.GetSection("AzureAd"));

        builder.Services.AddSingleton<IOptionsMonitor<OpenIdConnectOptions>, AzureADOpenIdConnectOptionsSetup>();

        builder.Services.AddAuthentication(auth =>
        {
            auth.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
            auth.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            auth.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
        })
        .AddOpenIdConnect();
        return builder;
    }

    public class AzureADOpenIdConnectOptionsSetup : IOptionsMonitor<OpenIdConnectOptions>
    {
        public OpenIdConnectOptions CurrentValue { get; set; }
        private IDataProtectionProvider _dataProtectionProvider;

        public AzureADOpenIdConnectOptionsSetup(IOptionsMonitor<AzureAdOptions> azureADOptions,IDataProtectionProvider dataProtectionProvider)
        {
            _dataProtectionProvider = dataProtectionProvider;
            CurrentValue = new OpenIdConnectOptions
            {
                ClientId = azureADOptions.CurrentValue.ClientId,
                Authority = $"{azureADOptions.CurrentValue.Instance}{azureADOptions.CurrentValue.TenantId}",
                CallbackPath = azureADOptions.CurrentValue.CallbackPath
            };
        }

        public OpenIdConnectOptions Get(string name)
        {
            OpenIdConnectPostConfigureOptions op = new OpenIdConnectPostConfigureOptions(_dataProtectionProvider);
            op.PostConfigure(name, CurrentValue);
            return CurrentValue;
        }

        public IDisposable OnChange(Action<OpenIdConnectOptions, string> listener)
        {
            throw new NotImplementedException();
        }
    }        
}

{

{

}
公共OpenIdConnectOptions获取（字符串名称）
{
返回当前值；
}
公共IDisposable OnChange（操作侦听器）
{

}
}

当我运行这段代码时，它两次命中构造函数和OpenIdConnectOptions，并通过构造函数级别的断点，检查设置是否正确地从azureADOptions传输到OpenIdConnectOptions CurrentValue。 尽管如此，我还是收到了一条错误消息（在我按下login之前，它意味着自己启动它）

InvalidOperationException：向OpenIdConnectOptions提供权限、元数据地址、配置或配置管理器

我不确定是否正确实现了OpenIdConnectOptions Get（字符串名）。

还有一个疑问是，我应该如何实现OnChange（Action listener）来监听appsettings.json的运行时更改。要返回

，需要初始化ConfigurationManager，并编写如下简单代码：

public class AzureADOpenIdConnectOptionsSetup : IOptionsMonitor<OpenIdConnectOptions>

    {
        CurrentValue = new OpenIdConnectOptions();

        CurrentValue.ClientId = azureADOptions.CurrentValue.ClientId;
        CurrentValue.Authority = azureADOptions.CurrentValue.Authority;
        CurrentValue.CallbackPath = azureADOptions.CurrentValue.CallbackPath;
    }

    public OpenIdConnectOptions Get(string name)
    {
        return CurrentValue;
    }
