Asp.net core使用session:
在新建Asp.net core应用程序后，要使用session中间件，在startup.cs中需执行三个步骤：
1.使用实现了IDistributedcache接口的服务来启用内存缓存。（例如使用内存缓存）
//该步骤需在addsession()调用前使用。
2.调用addsession方法
3.使用usesession回调（usesession需在useMvc()方法前调用）
具体代码如下：
public class Startup ???{ ???????public Startup(IConfiguration configuration) ???????{ ???????????Configuration = configuration; ???????} ???????public IConfiguration Configuration { get; } ???????// This method gets called by the runtime. Use this method to add services to the container. ???????public void ConfigureServices(IServiceCollection services) ???????{ ???????????services.AddDistributedMemoryCache(); ???????????services.AddSession(options => ???????????{ ???????????????options.Cookie.Name= ".AdventureWorks.Session"; ???????????????options.IdleTimeout = TimeSpan.FromSeconds(10);//设置session的过期时间 ???????????????options.Cookie.HttpOnly = true; ???????????} ???????????); ???????????services.AddMvc(); ???????} ???????// This method gets called by the runtime. Use this method to configure the HTTP request pipeline. ???????public void Configure(IApplicationBuilder app, IHostingEnvironment env) ???????{ ???????????if (env.IsDevelopment()) ???????????{ ???????????????app.UseDeveloperExceptionPage(); ???????????} ???????????app.UseSession(); ???????????app.UseMvc(); ???????}}Asp.net core如何使用Session
