我正在使用asp 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 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" });
