无法将lambda表达式转换为"CookieAuthenticationOptions"类型，因为它不是委托类型 [英] Cannot convert lambda expression to type 'CookieAuthenticationOptions' because it is not a delegate type

问题描述

我正在使用asp.net core的1.0.1版本，并且正在使用表单中的身份验证.

I'm using 1.0.1 version of asp.net core and I'm using authentication in my form.

我使用UseCookieAuthentication并给出了错误

无法将lambda表达式转换为类型"CookieAuthenticationOptions"，因为 它不是委托类型

Cannot convert lambda expression to type 'CookieAuthenticationOptions' because it is not a delegate type

在Startup.cs中，配置方法.

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    app.UseApplicationInsightsRequestTelemetry();

    app.UseExceptionHandler("/Home/Error");

    app.UseApplicationInsightsExceptionTelemetry();

    app.UseStaticFiles();
    app.UseSession();

    app.UseCookieAuthentication(options =>
    {
        options.AutomaticAuthenticate = true;
        options.AutomaticChallenge = true;
        options.LoginPath = "/Home/Login";
    });

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=About}/{id?}"
        );
    });
}

推荐答案

您需要传递选项，而不是lambda:

You need to pass in the options, not a lambda:

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AutomaticAuthenticate = true,
    AutomaticChallenge = true,
    LoginPath = "/Home/Login"
});
