ASP.NET Core 1.0中的会话

本文介绍了ASP.NET Core 1.0中的会话的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试在我的ASP.NET Core 1.0(vNEXT)项目中使用Session.这就是我的代码的样子.

I am trying to use Session in my ASP.NET Core 1.0 (vNEXT) project. This is how my code looks like.

public class Startup { // For more information on how to configure your application, visit go.microsoft/fwlink/?LinkID=398940 public void ConfigureServices(IServiceCollection services) { //-- Enabled MVC Pattern services.AddMvc(); //-- Enable Session handling services.AddCachingServices(); services.AddSessionServices(); } public void Configure(IApplicationBuilder app) { //-- User MVC app.UseMvc(); //-- Use Session app.UseSession(); app.UseInMemorySession(); } }

但是现在我被困住了.我不知道如何在控制器或页面中的会话中设置或获取数据.我已经尝试过this.Context.Session.但是它没有被实例化，所以当我尝试访问该属性时会抛出一个invalidexception.

But now I am stuck. I don't know how to set or get data from the session in my controller or pages. I have tried the this.Context.Session. But it's not instanced, so an invalidexception is throw when i try to access that properties.

任何具有有关如何使其正常工作的代码示例的人.

Anybody that has an code example on how to get this working.

谢谢.

以下是屏幕转储，其中base.context.Session在我的控制器中是什么样的.

Here is a screendump how the base.context.Session looks like in my controller.

我没有SetString()和GetString()，只有Set()和TryGet()...方法...

And I don't have the SetString() and GetString(), only the Set() and TryGet()... methods...

这是我的project.json文件的样子.

This is how my project.json file looks like.

"version": "1.0.0-*", "dependencies": { "Microsoft.AspNet.Server.IIS": "1.0.0-beta3", "Microsoft.AspNet.Mvc": "6.0.0-beta3", "Microsoft.AspNet.Session": "1.0.0-beta3" },

推荐答案

将我的评论更改为答案:

Changing my comment to an answer:

在需要会话中间件之前添加会话中间件.否则，它将无法在请求管道中的正确位置使用.

Add the session middleware before anything that needs it. Otherwise it won't be available at the right point in the request pipeline.

实质上，中间件是按顺序运行的-用.UseXyz()添加的每个中间件组件都按顺序运行.因此，如果MVC在会话之前运行，则MVC无法从会话中间件看到会话获取.

The middleware is in essence run sequentially - each middleware component that you add with .UseXyz() is run in order. So if MVC runs before Session, then MVC can't see the session acquisition from the Session middleware.
