.NetCore Session.Redis （转载）

首先创建ASP.NET CORE Web项目，然后按如下顺序操作。

1.添加nuget程序包:

Microsoft.AspNetCore.Session;
Microsoft.AspNetCore.DataProtection.Redis;
Microsoft.Extensions.Caching.Redis.Core;
Microsoft.Extensions.Caching.Redis
Microsoft.AspNetCore.Http;     //使用Session时有扩展方法

2.在appsettings.json中添加Redis配置:

{
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "WebConfig": {
    "Redis": {
      "Connection": "127.0.0.1:6379,defaultdatabase=1",
      //"Connection": "127.0.0.1:6379,allowAdmin=true,password=123456,defaultdatabase=5",
      "InstanceName": "Core_Redis_Session_"
    },
    "SessionTimeOut": "30" //session过期时长，分钟
  },
  "AllowedHosts": "*"
}

3.在startup.cs类中，按如下例子添加代码:

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

    /*
        *  Microsoft.AspNetCore.Session;
        *  Microsoft.AspNetCore.DataProtection.Redis;
        *  Microsoft.Extensions.Caching.Redis.Core;
        *  Microsoft.Extensions.Caching.Redis
        *  Microsoft.AspNetCore.Http;     //使用Session时有扩展方法
        */

    #region 使用Redis保存Session
    var redisConn = Configuration["WebConfig:Redis:Connection"];
    var redisInstanceName = Configuration["WebConfig:Redis:InstanceName"];
    //Session 过期时长分钟
    var sessionOutTime = Configuration.GetValue<int>("WebConfig:SessionTimeOut", );

    //var redis = StackExchange.Redis.ConnectionMultiplexer.Connect(redisConn);
    //services.AddDataProtection().PersistKeysToRedis(redis, "DataProtection-Test-Keys");
    services.AddDistributedRedisCache(option =>
    {
        //redis 连接字符串
        option.Configuration = redisConn;
        //redis 实例名
        option.InstanceName = redisInstanceName;
    }
    );
    #endregion

    //添加Session并设置过期时长
    services.AddSession(options => { options.IdleTimeout = TimeSpan.FromMinutes(sessionOutTime); });

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseSession();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

4.在控制器HomeController中添加：

public class HomeController : Controller
{
    public IActionResult Index()
    {
        ViewData["UserName"] = this.HttpContext.Session.GetString("UserName");
        ViewData["PassWord"] = this.HttpContext.Session.GetString("PassWord");
        return View();
    }

    [HttpPost]
    public NoContentResult Add(string userName, string pwd)
    {
        this.HttpContext.Session.SetString("UserName", userName);

        this.HttpContext.Session.SetString("PassWord", pwd);

        return NoContent();
    }
}

5.在View/Index.cshtml添加如下代码:

<form method="post" action="../Home/Add">
    <div>
        <input name="username" id="username" type="text" value="@ViewData["UserName"]" />
        <input name="pwd" id="pwd" type="password" value="" />
        <input type="submit" value="更新" />
        <h1>提交用户名称为：@ViewData["UserName"]    密码：@ViewData["PassWord"]</h1>
        <a href="javascript:void(0);" onclick="window.location.reload();">刷新显示最新值</a>
    </div>
</form>
