Asp.net core中使用session

时间:2023-02-03 21:25:58

1. NuGet包引用 Microsoft.AspNetCore.Session

2. Startup.cs中的相应方法加入些代码:  

       public void ConfigureServices(IServiceCollection services)    

     {            //添加session           

     services.AddDistributedMemoryCache();  

            services.AddSession();           

       services.AddMvc();     

    }

 

  public void Configure(IApplicationBuilder app, IHostingEnvironment env)       

  {         

        app.UseSession(); //必须加上这句才能用session      

      }

3.控制器中的使用;

using Microsoft.AspNetCore.Http;

 public IActionResult Show()
        {
            Request.HttpContext.Session.SetString("date",DateTime.Now.ToString());//设置session
            var tenantId = Request.HttpContext.Session.GetString("date");//获取session

        return View();
        }
