dotnet core 使用传统Cookie

dotnet core 使用传统Cookie

---

先在添加Cookie中间件 app.UseCookiePolicy();

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseBrowserLink();
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }
            app.UseCookiePolicy();
            app.UseStaticFiles();
            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }

测试：

public class HomeController : Controller
{
        public IActionResult Index()
        {
            var tmt = HttpContext.Request.Cookies["asdf"];
            HttpContext.Response.Cookies.Append("asdf", "Value");
            return View();
        }
}
