Google 身份验证异常 - 未配置身份验证处理程序来处理该方案：Cookies

Question

我在 .net 核心中使用 google 身份验证，但是当从 google 重定向时，它显示异常- InvalidOperationException：没有配置身份验证处理程序来处理该方案：Cookies

这是我的 startup.cs 设置

  app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            LoginPath = new PathString("/account/login"),
            AuthenticationScheme = "MyCookieMiddlewareInstance",
            AutomaticAuthenticate = true,
            AutomaticChallenge = true,
            AccessDeniedPath = new PathString("/Home/AccessDenied"),
        });

        app.UseGoogleAuthentication(new GoogleOptions
        {
            AuthenticationScheme = "Google",
            DisplayName = "Google",
            SignInScheme = "Cookies",
            ClientId = "ClientId ",
            ClientSecret = "ClientSecret ",
            Scope = { "email", "openid" },
            CallbackPath = "/home",
        });

请指出我哪里错了

Answer 1

您可以使用AddCookieAuthentication扩展方法注册ASP.NET Core提供的默认CookieAuthenticationHandler处理程序：

using Microsoft.AspNetCore.Authentication.Cookies;

public void ConfigureServices(IServiceCollection 服务) { services.AddCookieAuthentication(); ... }

更新：

身份验证中间件中有一个breaking change。现在 ASP.NET Core 只有一个 AddAuthentication() 扩展方法，所有配置都会抛出相应的 UseXXXAuthentication 扩展方法。举个简单的例子看看Security repo samples:

using Microsoft.AspNetCore.Authentication.Cookies;


public void ConfigureServices(IServiceCollection services)
{
    services.AddAuthentication();
}

public void Configure(IApplicationBuilder app)
{
     ...
     app.UseCookieAuthentication(new CookieAuthenticationOptions
     {
        AutomaticAuthenticate = true
     });
}
