Asp.net core如何使用Session

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）

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();//启用session之前必须先添加内存
                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;//设置在浏览器不能通过js获得该cookie的值
                }
                );
                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();
            }
