我正在尝试将 LinkedIn 身份验证添加到我的 ASP.NET Core 2.0 应用程序，但收到以下错误：

没有配置身份验证处理程序来处理该方案：LinkedIn

以下是我在 in 中添加 LinkedIn/OAuth 身份验证的ConfigureServices方法Startup.cs：

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
   .AddCookie("internal_cookie", options => {
         options.AccessDeniedPath = "/Account/Forbidden/";
         options.LoginPath = "/Account/Login";
    })
   .AddCookie("external_cookie")
   .AddOAuth("LinkedIn", options => {

         options.SignInScheme = "external_cookie";
         options.ClientId = "1234567890";
         options.ClientSecret = "1234567890";
         options.CallbackPath = "/linkedin-callback";

         options.AuthorizationEndpoint = "https://www.linkedin.com/oauth/v2/authorization";
         options.TokenEndpoint = "https://www.linkedin.com/oauth/v2/accessToken";
         options.UserInformationEndpoint = "https://api.linkedin.com/v1/people/~:(id,first-name,last-name,email-address,picture-url,picture-urls::(original))";

         options.Scope.Add("r_basicprofile");
         options.Scope.Add("r_emailaddress");

         options.Events = new OAuthEvents
         {
             OnCreatingTicket = OnCreatingTicketLinkedInCallBack,
             OnTicketReceived = OnTicketReceivedCallback
         };
    })
    .AddFacebook(options =>
    {
          options.AppId = "1234567980";
          options.AppSecret = "1234567890";
          options.Events = new OAuthEvents
          {
             OnCreatingTicket = OnCreatingTicketFacebookCallback,
             OnTicketReceived = OnTicketReceivedCallback
          };
     })
     .AddGoogle(options =>
     {
           options.ClientId = "1234567890";
           options.ClientSecret = "1234567890";
           options.CallbackPath = "/google-callback";
           options.Events = new OAuthEvents
           {
              OnCreatingTicket = OnCreatingTicketGoogleCallback,
              OnTicketReceived = OnTicketReceivedCallback
           };
});

我的错误在哪里？

更新：进行建议的更正后，我现在收到以下错误：

没有配置 IAuthenticationSignInHandler 来处理方案的登录：social_login

您将与您的自定义 LinkedIn 处理程序注册关联的身份验证方案与OAuthHandler最终将调用以保留身份的登录方案（通常是 cookie 处理程序实例）混合在一起。

修复您的注册以指定LinkedIn为方案和social_login登录方案（假设您的 cookie 处理程序确实命名为social_login），它应该可以工作：

services.AddAuthentication()
    .AddCookie("social_login")
    .AddOAuth("LinkedIn", options =>
    {
        options.SignInScheme = "social_login";

        // ...
    });

SignInScheme注意：如果social_login是默认登录方案，您可以删除分配（即，如果您调用services.AddAuthentication("social_login")或services.AddAuthentication(options => options.DefaultSignInScheme = "social_login")：

services.AddAuthentication("social_login")
    .AddCookie("social_login")
    .AddOAuth("LinkedIn", options =>
    {
        // ...
    });
