Asp.net core mvc Asp.Net MVC vNext身份登录路由更改不起作用

我正在尝试设置登录、注销等的新路径

现在，当我使用app.UseIdentity时，它会自动路由到/Account/Login

当我尝试注释app.UseIdentity并添加

MapRoute(
    name: "Login",
    defaults: new { controller = "Security", action = "Login" },
    template: "Login/{returnUrl?}")

及

它不做任何事情，除了路由到我的主页，并显示一个空白页，我认为，因为它是未经授权的

正确的方法是什么？

刚刚通过查看Asp.Net源代码找到了答案：

请显示Startup.cs文件。我已经编辑过以显示答案

//app.UseIdentity();

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationScheme = "Cookies",
    LoginPath = new PathString("/Login"),
    LogoutPath = new PathString("/Logout")
});

public static class MyIdentityExtensions
{
    public static IApplicationBuilder UseMyIdentity(this IApplicationBuilder app)
    {
        if (app == null) {
            throw new ArgumentNullException(nameof(app));
        }

        var options = app.ApplicationServices.GetRequiredService<IOptions<IdentityOptions>>().Value;

        app.UseCookieAuthentication(options.Cookies.ExternalCookie);
        app.UseCookieAuthentication(options.Cookies.TwoFactorRememberMeCookie);
        app.UseCookieAuthentication(options.Cookies.TwoFactorUserIdCookie);

        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            LoginPath = new PathString("/Login"), // REPLACED THIS
            LogoutPath = new PathString("/Logout"), // ADDED THIS
            AuthenticationScheme = options.Cookies.ApplicationCookieAuthenticationScheme,
            AutomaticAuthenticate = true,
            AutomaticChallenge = true,
            Events = new CookieAuthenticationEvents
            {
                OnValidatePrincipal = SecurityStampValidator.ValidatePrincipalAsync
            }
        });

        return app;
    }
}

app.UseMyIdentity()
