Google身份验证例外 - 未配置身份验证处理程序来处理该方案：Cookie

Question

我在.net核心中使用谷歌身份验证但是当从谷歌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",
        });

请建议我错在哪里

Answer 1

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

using Microsoft.AspNetCore.Authentication.Cookies;

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

更新：

身份验证中间件中有breaking change。现在ASP.NET Core只有一个AddAuthentication()扩展方法，所有配置都抛出相应的UseXXXAuthentication扩展方法。有关简单示例，请查看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
     });
}
