.NetCore Session.Redis
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", 30); //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>
