在Core2.1中启用Session
Startup.cs文件进行配置
ConfigureServices方法的配置
在 services.AddMvc(....);这句上面加上
services.AddSession(options =>
???????????{
???????????????options.IdleTimeout = TimeSpan.FromMinutes(30);
???????????});
这里面的30是指Session的生命周期为30分钟
???????// This method gets called by the runtime. Use this method to add services to the container. ???????public void ConfigureServices(IServiceCollection services) ???????{ ???????????services.Configure<CookiePolicyOptions>(options => ???????????{ ???????????????// This lambda determines whether user consent for non-essential cookies is needed for a given request. ???????????????options.CheckConsentNeeded = context => true; ???????????????options.MinimumSameSitePolicy = SameSiteMode.None; ???????????}); ???????????services.AddSession(options => ???????????{ ???????????????options.IdleTimeout = TimeSpan.FromMinutes(30); ???????????}); ???????????services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1); ???????}Configure方法中的配置
在 app.UseMvc(...);的上面加上
app.UseSession();
???????// 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(); ???????????} ???????????else ???????????{ ???????????????app.UseExceptionHandler("/Home/Error"); ???????????????app.UseHsts(); ???????????} ???????????app.UseHttpsRedirection(); ???????????app.UseStaticFiles(); ???????????app.UseCookiePolicy(); ???????????app.UseSession(); ???????????app.UseMvc(routes => ???????????{ ???????????????routes.MapRoute( ?????????????????name: "areas", ?????????????????template: "{area:exists}/{controller=Home}/{action=Index}/{id?}" ???????????????); ???????????????routes.MapRoute( ???????????????????name: "default", ???????????????????template: "{controller=Home}/{action=Index}/{id?}"); ???????????}); ???????}在使用Session的页面中添加using引用
using Microsoft.AspNetCore.Http;
Microsoft.AspNetCore.Http的方法
namespace Microsoft.AspNetCore.Http{ ???public static class SessionExtensions ???{ ???????public static byte[] Get(this ISession session, string key); ???????public static int? GetInt32(this ISession session, string key); ???????public static string GetString(this ISession session, string key); ???????public static void SetInt32(this ISession session, string key, int value); ???????public static void SetString(this ISession session, string key, string value); ???}}Get为获取值
HttpContext.Session.GetString("username");Set为设置
HttpContext.Session.SetString("username", "admin");.NetCore中Session的使用
