c# - ASP.NET Core 2.0 - 必须提供 ArgumentException : Options. ClientId

Question

我有一个 .NET Core 1.1 应用程序，我希望升级到 .NET Core 2.0。更新目标框架和所有依赖项后，我发现我的身份验证设置无法编译。我已更新以说明已删除的属性和已弃用/已移动的方法调用。省略号用于表示为简洁起见而省略的代码。

每当我启动我的应用程序时，我现在都会收到以下错误

1.1 代码 - Startup.cs 的 public void Configure() 方法内部

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationScheme = "Cookies",
    ExpireTimeSpan = TimeSpan.FromHours(12),
    SlidingExpiration = false,
    CookiePath = CookiePath,
    CookieName = "MyCookie"
});

var openIdConnectionOptions = new OpenIdConnectOptions
{
    ClientId = Configuration["OpenIdSettings:ClientId"],
    ClientSecret = Configuration["OpenIdSettings:ClientSecret"],
    Authority = Configuration["OpenIdSettings:Authority"],
    MetadataAddress = $"{Configuration["OpenIdSettings:Authority"]}/.well-known/openid-configuration",
    GetClaimsFromUserInfoEndpoint = true,
    AuthenticationScheme = "oidc",
    SignInScheme = "Cookies",
    ResponseType = OpenIdConnectResponseType.IdToken,
    TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
    {
        // This sets the value of User.Identity.Name to users AD username
        NameClaimType = IdentityClaimTypes.WindowsAccountName,
        RoleClaimType = IdentityClaimTypes.Role,
        AuthenticationType = "Cookies",
        ValidateIssuer = false
    }
};

// Scopes needed by application
openIdConnectionOptions.Scope.Add("openid");
openIdConnectionOptions.Scope.Add("profile");
openIdConnectionOptions.Scope.Add("roles");

app.UseOpenIdConnectAuthentication(openIdConnectionOptions);

我正在阅读的所有内容都表明此过程已移至 ConfigureServices 方法。这是我的 Core 2.0 新代码

public void ConfigureServices(IServiceCollection services)
{
    ...

    services.AddAuthentication(options =>
    {
        options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
        options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
    }).AddCookie(options => new CookieAuthenticationOptions
    {
        //AuthenticationScheme = "Cookies", // Removed in 2.0
        ExpireTimeSpan = TimeSpan.FromHours(12),
        SlidingExpiration = false,
        Cookie = new CookieBuilder
        {
            Path = CookiePath,
            Name = "MyCookie"
        }
    }).AddOpenIdConnect(options => GetOpenIdConnectOptions());

    ...
}

public void Configure(IApplicationBuilder app)
{
    ...
    app.UseAuthentication();
    ...
}
private OpenIdConnectOptions GetOpenIdConnectOptions()
{
        var openIdConnectionOptions = new OpenIdConnectOptions
        {
            ClientId = Configuration["OpenIdSettings:ClientId"],
            ClientSecret = Configuration["OpenIdSettings:ClientSecret"],
            Authority = Configuration["OpenIdSettings:Authority"],
            MetadataAddress = $"{Configuration["OpenIdSettings:Authority"]}/.well-known/openid-configuration",
            GetClaimsFromUserInfoEndpoint = true,
            SignInScheme = "Cookies",
            ResponseType = OpenIdConnectResponseType.IdToken,

            TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
            {
                // This sets the value of User.Identity.Name to users AD username
                NameClaimType = IdentityClaimTypes.WindowsAccountName,
                RoleClaimType = IdentityClaimTypes.Role,
                AuthenticationType = "Cookies",
                ValidateIssuer = false
            }
        };

        // Scopes needed by application
        openIdConnectionOptions.Scope.Add("openid");
        openIdConnectionOptions.Scope.Add("profile");
        openIdConnectionOptions.Scope.Add("roles");

        return openIdConnectionOptions;
    }

我正在我的 GetOpenIdConnectOptions 中设置 ClientId(或者我认为是这样)，所以我不清楚错误指的是什么 ClientId。在此处输入代码

编辑:应用设置.json

"OpenIdSettings": {
  "Authority": "https://myopenidauthenticationendpointurl",
  "ClientId": "myappname",
  "CookiePath":  "mypath"
}

Answer 1

.AddOpenIdConnect(options => GetOpenIdConnectOptions());

您的 GetOpenIdConnectOptions() 助手返回一个新的 OpenIdConnectOptions 实例，而不是更新由 options = > ... 委托(delegate)。

修复您的方法以获取现有的 OpenIdConnectOptions 值，它应该可以工作:

services.AddAuthentication()
    .AddOpenIdConnect(options => SetOpenIdConnectOptions(options));

private void SetOpenIdConnectOptions(OpenIdConnectOptions options)
{
    options.ClientId = Configuration["OpenIdSettings:ClientId"];
    options.ClientSecret = Configuration["OpenIdSettings:ClientSecret"];
    options.Authority = Configuration["OpenIdSettings:Authority"];
    options.MetadataAddress = $"{Configuration["OpenIdSettings:Authority"]}/.well-known/openid-configuration";
    options.GetClaimsFromUserInfoEndpoint = true;
    options.SignInScheme = "Cookies";
    options.ResponseType = OpenIdConnectResponseType.IdToken;

    options.TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
    {
        // This sets the value of User.Identity.Name to users AD username
        NameClaimType = IdentityClaimTypes.WindowsAccountName,
        RoleClaimType = IdentityClaimTypes.Role,
        AuthenticationType = "Cookies",
        ValidateIssuer = false
    };

    // Scopes needed by application
    options.Scope.Add("openid");
    options.Scope.Add("profile");
    options.Scope.Add("roles");
}
